Which of the following is a monomial ? *(d) a + b + c + d.(b) a + 6(a) 4x²(c) a + 6 + c​

Answers

A monomial is an algebraic expression that consists of only one term. Examples of monomials include 4x², a + 6, and a + b + c + d.

In the given example, (a) 4x² is a monomial because it consists of only one term, 4x². (b) a + 6 is also a monomial because it consists of only one term, a + 6. (c) a + 6 + c is not a monomial because it consists of more than one term, namely a + 6 and c. (d) a + b + c + d is also not a monomial because it consists of more than one term, namely a, b, c, and d.

To calculate the value of a monomial, we must first determine its degree. The degree of a monomial is the sum of the exponents of its variables. For example, the degree of 4x² is 2 because it consists of only one variable, x, with an exponent of 2.

Once the degree of a monomial is determined, its value can be calculated by substituting the values of its variables. For example, if x = 3, then 4x² = 4(3)² = 36.

In summary, a monomial is an algebraic expression that consists of only one term. Its degree is the sum of the exponents of its variables. To calculate its value, substitute the values of its variables into the expression.

Answers

Answer:

2+2%2%5+51%895%+8+81%9+61%+5%+8+%15+%

Answer:

(- 8, - 6 )

Step-by-step explanation:

y = 2x + 10 → (1)

y = x + 2 → (2)

substitute y = 2x + 10 into (2)

2x + 10 = x + 2 ( subtract x from both sides )

x + 10 = 2 ( subtract 10 from both sides )

x = - 8

substitute x = - 8 into either of the 2 equations and evaluate for y

substituting into (2)

y = - 8 + 2 = - 6

solution is (- 8, - 6 )

what is trigonometric ratios ?

The values of all trigonometric functions depending on the side ratio of a right-angled triangle are known as trigonometric ratios. The ratios of a right-angled triangle's sides to any acute angle are the angle's trigonometric ratios.

given

one side = 16

angle = 69°

one angle = 90° as right angle triangle

another angle = 69°+ 90° + x = 180°

= 155° + x = 180°

x = 25°

a / sin69° = 16 / sin25°

a = 35. 38

A moving company want to buy a new type of truck and need to know the volume of the torage compartment before they can decide if they hould purchae the truck. What’ i the volume of the torage compartment

Answers

The volume of the storage compartment is 1246 cube ft.

In the given question, we have to find the volume of the storage compartment.

The diagram of the question is given below.

If we see the diagram it forms two recatangle with the lengths given below.

As we know that the volume of the cuboid is

V = LBH

where, L = length, B = breadth, H = Height

Now finding the volume of the cuboid A.

So V(A) = 10*8*15

V(A) = 1200 cube ft

Now finding the volume of the cuboid B.

So V(B) = 2*8*3

V(B) = 48 cube ft

Now the volume of the storage compartment is the sum of the volume of cuboid A and volume of the cuboid B, then we subtract 2 ft because we count the 2 ft of height two times.

The volume of storage compartment = volume of the cuboid A + volume of the cuboid B - 2 ft

The volume of storage compartment = 1200 + 48 - 2

The volume of storage compartment = 1248 - 2

The volume of storage compartment = 1246 cube ft

Debbie's bank offers an online bill pay service. For this, the bank charges $2.25

per month plus $0.10 per bill paid using the service. How many bills does she pay

each month if the charges are always between $3.50 and $5.00? (Note: She is not

allowed to pay part of a bill.)


please write as an inequality and show work

Answers

We know that the bank charges $2.25 per month plus $0.10 per bill paid using the service. Let x be the number of bills paid using the service.

The total cost of the service is:

Cost = 2.25 + 0.10x

We also know that the charges are always between $3.50 and $5.00. So we can write this as an inequality:

3.50 <= Cost <= 5.00

To find the number of bills, we can substitute the expression for cost into the inequality:

3.50 <= 2.25 + 0.10x <= 5.00

We can solve this inequality by isolating x on one side:

0.10x >= 1.25

x >= 12.5

So the number of bills paid using the service is greater than or equal to 12.5.

She could pay exactly 12 bills, 13 bills, 14 bills and so on.

The solution is x >= 12.5

Let's call the number of bills paid per month as "x"

We know that the total cost is:

$2.25 (fixed monthly fee) + $0.10x (cost per bill paid)

We also know that the total cost is between $3.50 and $5.00

Therefore, $3.50 <= $2.25 + $0.10x <= $5.00

To solve for x, we can first isolate x by subtracting $2.25 from both sides of the inequality:

$1.25 <= $0.10x <= $2.50

Now we can divide both sides of the inequality by $0.10 to get:

12.5 <= x <= 25

It means that the number of bills paid per month using the service is between 12 and 25 bills, Debbie can pay at least 12 bills and at most 25 bills.

Answers

The expression that that represents the cost of the dinner plus tip is d(23/100+1)

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power. In other words, none of the exponents can be greater than 1.

Some of the examples of linear equations are 2x – 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, 3x – y + z = 3

The cost of the dinner = d

the cost of the tip is 23% of the cost of the dinner = 23/100 × d = 23d/100

Therefore the total cost of the dinner and the tip = 23d/100 + d

by bringing d out

2.) There were 145 pounds of flour at the bakery at the start of the day. The bakery uses 111 pounds of flour by the end of the day. What percent of flour did they use?​

Answers

The bakery used 76.55 % of the flour by the end of the day.

How to calculate Percentage?

The percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.

To find the percent of flour used by the bakery, we need to divide the amount of flour used by the total amount of flour and then multiply by 100 to convert the decimal to a percentage.

We can use the formula:

percent used = (the amount used / total amount) x 100

In this case:

percent used = (111 / 145) x 100 = 76.55 %

Hence, The bakery used 76.55 % of the flour by the end of the day.

Answers

Answer:

x = 5, -5, 3, -3

Step-by-step explanation:

First, substitute u = x^2 into the equation, and we have

u^2 - 34u + 225 = 0

u = x^2

Factor u^2 −34u +225 using the AC method, and we get

( u - 25) ( u - 9) = 0

We know If any individual factor on the left side of the equation is equal to

0, the entire expression will be equal to 0, so

u - 25 = 0

u - 9 = 0

Next, we set u - 25 equal to 0  and solve for u, and we get

u = 25

Then set u - 9 equal to 0 and solve for u, and we get

u = 9

The final solution is all the values that make (u−25)(u−9) = 0  true.

u =25,9

Substitute the real value of u=x^2 back into the solved equation.

x^2 = 25

(x^2)^1 = 9

x^2 = 25

x = 5, -5

Now we solve the second equation

(x^2)^1 = 9

x = 3, -3

So, the answers are: 5, -5, 3, -3

How do you change the base of an exponential function?

Answers

To change the base of an exponential function, we can use the formula:

log_b(a) = log_c(a) / log_c(b).

To change the base of an exponential function, you can use the property that logarithms with different bases are related by the following equation:

log_b(a) = log_e(a) / log_e(b)

Where log_b(a) is the logarithm of a to the base b and log_c(a) is the logarithm of a to the base e.

For example: To change log_3(7) to log_e(x)/log_e(y), we can use the property that logarithms with different bases are related by the following equation:

logb(a) = logc(a) / logc(b)

So log_3(7) = log_e(7) / log_e(3)

To find x and y we can use the logarithm properties and the definition of logarithm:

x = 7

log_e(y) = log_e(3)
