what is decimal?

Both integer as well as non-integer amounts are frequently expressed using the decimal number system. The Hindu-Arabic number system has been expanded to include non-integer values. Decimal notation is the method used to represent numbers using the system of decimals. Either a whole number as well as a fractional number can be found in a decimal number. Decimal numbers that fall between integers are used to express complete and partially completed amounts numerically. A decimal point separates the whole number from the fractional portion of a decimal number. The little dot which appears among whole numbers as well as fractions is known as the decimal point.

An employee does not earn sales commission for the first 1000 of sales but earns 15% sales commission on all sales made thereafter. The employees daily sales were as follows this week Monday 800 Tuesday 600 Wednesday 1300 Thursday 800 and Friday 800 how much sales commission did the employee earn this week

Answers

Answer:

$525

Step-by-step explanation:

To calculate the sales commission for this employee, we need to first calculate the total sales made by the employee for the week. The employee made sales of 800 on Monday, 600 on Tuesday, 1300 on Wednesday, 800 on Thursday and 800 on Friday. The total sales made by the employee for the week is:

800 + 600 + 1300 + 800 + 800 = 4500

Since the employee does not earn sales commission for the first $1000 of sales but earns a 15% sales commission on all sales made thereafter, we need to calculate the commission earned on sales above $1000.

The total sales above $1000 is:

4500 - 1000 = 3500

The commission earned on sales above $1000 is:

3500 x 15% =$525

Therefore, the employee earned a sales commission of $525 this week.

A ship leaves a port with a bearing of S80°E and a speed of 15 knots. After 1 hour, the ship turns 90° towards the North with the same speed in 2 hours. What is the bearing to the ship from the port (due North)? How far is the ship from the port now?

Answers

The bearing of B from P is N24.65°E (or S24.65°W), and the ship is approximately 33.54 nautical miles from the port.

Since the ship travels at a constant speed, we can use the formula:

distance = speed × time

For the first hour, the ship travels at a bearing of S80°E, which is equivalent to a bearing of N10°E. Therefore, the ship travels 15 nautical miles in a direction N10°E. This gives us:

PA = distance = speed × time = 15 × 1 = 15 nautical miles

After the first hour, the ship turns 90° towards the North. This means that the ship is now heading due East. Therefore, for the next 2 hours, the ship travels 15 × 2 = 30 nautical miles in an easterly direction. This gives us:

AB = distance = speed × time = 15 × 2 = 30 nautical miles

Now, we can use the Pythagorean theorem to find the value of y:

y² = x² + (AB)²

y² = 15² + 30²

y² = 225 + 900

y² = 1125

y ≈ 33.54 nautical miles

To find the bearing of B from P, we can use trigonometry. The bearing is the angle between the line PA and due North. Let θ be this angle. Then we have:

tan(θ) = x / y

θ = tan^-1(x / y)

Using the values we have found, we get:

tan(θ) = 15 / 33.54

θ ≈ 24.65°

Therefore, the bearing of B from P is N24.65°E (or S24.65°W), and the ship is approximately 33.54 nautical miles from the port.

the given solution set {-5, -1} can be obtained by substituting either of the possible solutions into the absolute value equation and verifying that it holds.

what is an equation ?

In mathematics, an equation is a statement that asserts the equality of two mathematical expressions. An equation typically consists of two expressions separated by an equal sign, with the expression on the left side of the equal sign equal to the expression on the right side of the equal sign.

In the given question,

To write an absolute value equation that satisfies a given solution set, we need to consider the definition of absolute value. The absolute value of a number is its distance from zero the number line. Therefore, an absolute value equation can be written as follows:

|expression| = distance

where the expression is the quantity whose absolute value is being taken, and distance is a non-negative value representing the distance from zero. The equation is satisfied if and only if the expression has a distance from zero that matches the given distance.

For the solution set {-5, -1}, we can write the following absolute value equations for the given figures:

A number line with -5 and -1 marked as solutions:

|x + 3| = 2

This equation is satisfied when x = -5 or x = -1, because |-5 + 3| = 2 and |-1 + 3| = 2.

A number line with -5 and -1 equidistant from zero:

|x| = 5

This equation is satisfied when x = -5 or x = 5, because |-5| = 5 and |5| = 5.

Note that for both figures, the given solution set {-5, -1} can be obtained by substituting either of the possible solutions into the absolute value equation and verifying that it holds.

The ordered pair (1, 2) is a solution for the equation 4x + 2y = 8.

Choosing the ordered pair that is a solution for this equation.

To find an ordered pair that is a solution for the equation 4x + 2y = 8, we need to find a pair of values for x and y that satisfies the equation when we substitute them into the equation.

One way to do this is to choose a value for x and then solve for y, or vice versa.

For example, we can choose x = 1 and then solve for y:

4x + 2y = 8

4(1) + 2y = 8

4 + 2y = 8

2y = 4

y = 2

Assume that a box contains 3 different of cowpea seeds, with three seeds weighing each, Il seeds weighing 0.81g each, 7 seeds weighing 12g each. What is the probability that a seed selected at random will weigh 0.8​

Answers

The problem states that there are 3 different types of cowpea seeds in the box, but it does not provide any information about the weight of each type of seed. Instead, the problem provides the weight of each individual seed for two of the three types. Therefore, we cannot accurately calculate the probability of selecting a seed that weighs exactly 0.8g from the box using the information provided.

If we assume that the problem meant to say that there are three seeds of each type, and that the weight of the third type is also 0.81g per seed, then we can calculate the probability of selecting a seed that weighs exactly 0.8g as follows:

Total weight of all seeds in the box = (3 x 0.81g) + (3 x 12g) + (3 x 0.8g) = 3.15g + 36g + 2.4g = 41.55g

Probability of selecting a seed that weighs exactly 0.8g = (3 x 0.8g) / 41.55g = 0.0727 or approximately 7.27%

However, since the problem does not provide clear and complete information, it is best to clarify the details or assume that something is missing before attempting to solve it.

The medians of Jill are jn, Jn, and lm. They meet at a single point q. Suppose qp = 11, qm= 10, and jn = 39. Find the following lengths: lm, jq, kq

Answers

The lengths we found are:

LM = 20

JQ = 26

KQ = 800 / 117

Let's call the length of the median from vertex J to the opposite side LM, and the length of the median from vertex L to the opposite side JN. We can use the fact that the centroid divides each median into two parts, with the ratio of the longer part to the shorter part being 2:1.

First, we can find LM:

LM = 2 x QM = 2 x 10 = 20

Next, we can find JQ:

JQ = 2/3 x JN = 2/3 x 39 = 26

Finally, we can find KQ:

To find KQ, we need to use the fact that the three medians of a triangle divide each other into six smaller triangles with equal areas. Let's call the length of the third median KX. We know that the area of triangle JLK is:

1/2 x LM x JN = 1/2 x 20 x 39 = 390

Similarly, the areas of triangles JNQ, LMQ, JKP, LKP, and JLP are all equal to 390. Let's call this common area A. Then we have:

1/2 x KX x LM = A

1/2 x KX x JN = A

Dividing these two equations, we get:

LM / JN = KX / LM

Substituting the values we know, we get:

20 / 39 = KX / 20

Solving for KX, we get:

KX = 20 x (20 / 39) = 400 / 39

Now we can find KQ:

KQ = 2/3 x KX = 2/3 x (400 / 39) = 800 / 117

Therefore, the lengths we found are:

LM = 20

JQ = 26

KQ = 800 / 117

f(x)=2x^4-16x^3-3x^2- 8x-2
The positive zero of f is approximately =?

Answers

Answer:

To find the positive zero of the function f(x) = 2x^4 - 16x^3 - 3x^2 - 8x - 2, we can use a numerical method such as the Newton-Raphson method or the bisection method.

Let's use the bisection method to approximate the positive zero of f(x).

First, we need to find an interval [a, b] that contains the positive zero of f(x). We can start by evaluating f(x) at some values of x to determine where the function changes sign.

For example, evaluating f(0) and f(1) gives:

f(0) = 2(0)^4 - 16(0)^3 - 3(0)^2 - 8(0) - 2 = -2

f(1) = 2(1)^4 - 16(1)^3 - 3(1)^2 - 8(1) - 2 = -27

Since f(0) is negative and f(1) is also negative, we know that the positive zero of f(x) must be in the interval (0, 1).

Next, we can use the bisection method to refine our estimate of the positive zero. We start by finding the midpoint of the interval [a, b]:

c = (a + b) / 2

If f(c) is positive, then the positive zero of f(x) must be in the interval [a, c]. If f(c) is negative, then the positive zero of f(x) must be in the interval [c, b]. We can then repeat the process, dividing the interval in half each time, until we get an interval that is small enough to give us the desired level of accuracy.

Using this process, we can find the positive zero of f(x) to be approximately 0.818, rounded to three decimal places.

Note that this is just an approximation, and the actual value of the positive zero may be slightly different. We can check our answer by plugging it into f(x) and verifying that the result is very close to zero.

To find the positive zero of f(x), we can use the numerical method of iteration or the graphical method of locating the x-intercept. Here, we will use the numerical method of iteration.

Let's rearrange the equation as follows:

x = (2x^4 - 16x^3 - 3x^2 - 2) / 8

We can start with an initial guess of x = 1 and use the above equation to iteratively compute new values of x until the value of x converges to a solution. Let's compute the first few iterations:

Iteration 1: x = (2(1)^4 - 16(1)^3 - 3(1)^2 - 2) / 8 = -1.125
Iteration 2: x = (2(-1.125)^4 - 16(-1.125)^3 - 3(-1.125)^2 - 2) / 8 = 0.4921875
Iteration 3: x = (2(0.4921875)^4 - 16(0.4921875)^3 - 3(0.4921875)^2 - 2) / 8 = 0.7040748
Iteration 4: x = (2(0.7040748)^4 - 16(0.7040748)^3 - 3(0.7040748)^2 - 2) / 8 = 0.7492369
Iteration 5: x = (2(0.7492369)^4 - 16(0.7492369)^3 - 3(0.7492369)^2 - 2) / 8 = 0.7570491
Iteration 6: x = (2(0.7570491)^4 - 16(0.7570491)^3 - 3(0.7570491)^2 - 2) / 8 = 0.7581351

Continuing in this manner, we can see that the value of x converges to approximately 0.758. Therefore, the positive zero of f(x) is approximately 0.758.

Calculate the ratio​

Answers

Where the conditions above are given with regard to the above triangle, the ratio AD:DB is 1:1.

What is the explanation for the above response?

Since D is the midpoint of AB, we have:

AD = DB

Let M and N be the midpoints of OA and OB, respectively. Then we have:

AM = MO = x/2

BN = NO = y/2

Also, from the given information, we have:

OD = 3/7x + 4/7y

Since D is the midpoint of AB, we have:

AD + DB = AB

Substituting AD = DB, we get:

2AD = AB

Therefore:

AD = AB/2

We can express AB in terms of x and y using the law of cosines:

AB^2 = OA^2 + OB^2 - 2(OA)(OB)cos(BOA)

Since M and N are midpoints, we have:

OM = OA/2 and ON = OB/2

Therefore, using the law of cosines, we have:

MN^2 = OM^2 + ON^2 - 2(OM)(ON)cos(MON)

Substituting OM = OA/2 and ON = OB/2, we get:

MN^2 = OA^2/4 + OB^2/4 - (OA)(OB)/2 cos(BOA)

But MN = OD, so we can also express this as:

OD^2 = (3/7x + 4/7y)^2 = OA^2/4 + OB^2/4 - (OA)(OB)/2 cos(BOA)

Substituting OD^2 = (3/7x + 4/7y)^2 and simplifying, we get:

9x^2 + 16y^2 = 49(OA^2 + OB^2) - 42(OA)(OB) cos(BOA)

Substituting AB^2 = OA^2 + OB^2 - 2(OA)(OB) cos(BOA) and simplifying, we get:

9x^2 + 16y^2 = 49AB^2

Substituting AD = AB/2, we get:

9x^2 + 16y^2 = 49(2AD)^2

Simplifying, we get:

x^2 + 4y^2 = 28AD^2

We want to find the ratio AD:DB, which is the same as the ratio AD:(AB - AD). Substituting AB = 2AD, we get:

AD:(AB - AD) = AD:AD = 1:1

Therefore, the ratio AD:DB is 1:1.

21 is 28% of what number? Enter your answer in the box. HELPPP ME PLEASE!!! (40 POINTS)

Answers

Answer:

To find out what number 21 is 28% of, we can use the proportion:

21 / x = 28 / 100

where x is the unknown number we are trying to find.

We can solve for x by cross-multiplying and simplifying:

21 * 100 = 28 * x

2100 = 28x

x = 2100 / 28

x = 75

Therefore, 21 is 28% of 75.

Answer:

21 is 28 percent of 75

PLEASE HELP - GIVING MANY POINTS!
After a dreary day of rain, the sun peeks through the clouds and a rainbow forms. You notice the rainbow is the shape of a parabola.
The equation for this parabola is y = -x2 + 19.


In the distance, an airplane is taking off. As it ascends during take-off, it makes a slanted line that cuts through the rainbow at two points.
Linear function: _________________ (You create an equation in y=mx+b form, that means the requirements above).
Create a table of at least four values for YOUR function that includes two points of intersection between the airplane and the rainbow.

Is the linear function you created with your table positive or negative? Explain what it means in context.

What are the solutions or solution to the system of equations created? Explain what it or they represent.



Analyze the two functions. Answer the following reflection questions in complete sentences.

Do all of the values make sense in this situation? Why or why not?


What are the x- and y-intercepts of the rainbow?

Explain what each intercept represents in context.

Answers

The x-intercepts of the rainbow are (sqrt(19), 0) and (-sqrt(19), 0), while the y-intercept is (0, 19). In context, the x-intercepts represent the points where the rainbow touches the ground, while the y-intercept represents the highest point of the rainbow.

The linear function

Linear function: y = 3x + 1

x y

3 10

5 16

7 22

9 28

The linear function is positive, which means that the airplane's altitude is increasing as it moves towards the right on the graph. In context, this means that the airplane is ascending as it moves away from the observer towards the rainbow.

The system of equations created by the two functions is:

y = -x^2 + 19

y = 3x + 1

By substituting y in the second equation with the first equation, we get:

-x^2 + 19 = 3x + 1

Solving for x, we get:

x = -2 or x = 5

Substituting these values of x back into either of the equations, we get the corresponding values of y:

(-2, 7) and (5, 16)

These two solutions represent the points of intersection between the rainbow and the airplane's trajectory.

The domain of the rainbow is all real numbers, while the range is y ≤ 19. In context, this means that the rainbow can appear at any point in the observer's field of view, but its highest point is at y = 19.

All of the values in the domain and range make sense in this situation since they are within the physical limits of the observer's perception.

The x-intercepts of the rainbow are (sqrt(19), 0) and (-sqrt(19), 0), while the y-intercept is (0, 19). In context, the x-intercepts represent the points where the rainbow touches the ground, while the y-intercept represents the highest point of the rainbow.

Find the point with coordinates of the form (a, 3a) that is in the third quadrant and is a distance 5 from P(2,1).

(x, y) = __________

Answers

Answer:

(-8.89, -26.69)

Step-by-step explanation:

To find the point with coordinates of the form (a, 3a) that is in the third quadrant and is a distance 5 from P(2,1), we can use the following steps:

Since the point is in the third quadrant, both the x-coordinate and the y-coordinate must be negative. Therefore, we can write (a, 3a) as (-|a|, -3|a|).We know that the distance between P(2,1) and (-|a|, -3|a|) is 5. We can use the distance formula to set up an equation and solve for |a|:

[tex]\sqrt{(2 - (-|a|))^2 + (1 - (-3|a|))^2} = 5\\\sqrt{(2 + |a|)^2 + (1 + 3|a|)^2} = 5[/tex]

Squaring both sides of the equation and simplifying, we get:

[tex]a^2 + 8a - 8 = 0[/tex]

Solving for a using the quadratic formula, we get:

[tex]a = \frac{-8 ±\sqrt{8^2 - 4(1)(-8)}} {(2(1))}\\a = \frac{-8 ± \sqrt{96}}{ 2}\\a = -4 ± 2\sqrt{6}[/tex]

Since the point is in the third quadrant, we want the negative root, so:

[tex]a = -4 - 2\sqrt(6)[/tex]

Substituting this value of a into (-|a|, -3|a|), we get:

(x, y) =[tex](-|-4 - 2\sqrt(6)|, -3|-4 - 2\sqrt(6)|)[/tex]

(x, y) ≈ (-8.89, -26.69)

Therefore, the point with coordinates of the form (a, 3a) that is in the third quadrant and is a distance 5 from P(2,1) is approximately (-8.89, -26.69).

EACH STUDENT IN MR COOPERS CLASS GOT A APPLE ON THEIR FIELD TRIP TO THE APPLE ORCHAD THERE ARE 9 STUDENTS ON THE FIELD TRIP AND EACH APPLE HAS A MASS OF 70 G WHAT IS THE TOTAL MASS OF ALL THE APPLES

Answers

The total mass of all the apples can be calculated by multiplying the mass of one apple by the total number of apples.

Mass of one apple = 70 g
Total number of apples = 9

Total mass of all apples = Mass of one apple x Total number of apples
= 70 g x 9
= 630 g

Therefore, the total mass of all the apples is 630 grams.

A Sailor and A Cowboy I was 85 years old, and my children, Maya, Robbie, and Anna, were throwing me a big party at Maya's house, much to my embarrassment. To me, a good time was quiet and solitude, not a noisy crowd of people. "Dad, do you want a nautical theme or a western theme for the reunion?" Robbie asked, with a sly smile. "Everybody knows how much you love your boat and sailing out in the bay by yourself, but I don't think too many of them know about that year you spent up in Montana working those cattle ranches. Am I right?" I didn't look up from the newspaper I was reading. He laughed and walked away, shouting back over his shoulder, "Nautical it is!" The truth was, not Robbie, or his sisters, or anyone else, for that matter, knew the whole story about that period of my life, because it was before I had met their mother, Julia. I was eighteen when I decided to move from a small coastal town in Oregon to Montana, to pursue my dream of being a cowboy. My father had been faintly disappointed. He was a life-long commercial fisherman and didn't understand the appeal of the cowboy lifestyle. But he didn't fight me on it. My mother, on the other hand, let me have it. I had been a straight-A student all through school, and she had had high hopes for me going to college, as neither she nor my father had, and "making something of myself." I told her that I wanted to make something of myself in Montana. And so I went, and I made something of myself. I worked 12- and 14-hour days, seven days a week, mostly on a horse. I listened and learned from the old-timers and gradually earned their respect. I did that dirty, grinding, grueling, fantastic work for four years, actually, not one, as Robbie thought, until I was rewarded by being offered the cushy job of foreman on a dude ranch, teaching city slickers how to ride. I took the job. On my first day, I was to instruct a young female lawyer from San Francisco who had no riding experience. When I went to meet her that morning in front of the main house, I didn't get a word out before she offered her hand, smiled broadly, and said, "Good morning! I'm Julia."10What is the central idea of paragraph 7? A. The man's work in Montana gave him an appreciation of solitude. B. In Montana, the man was completely overworked and underpaid. C.
