If the points lie on a straight line passing through the origin, it would support Enid's claim that the distance she jogs and the number of calories she burns are in a proportional relationship.

What is proportion ?

Proportion refers to the relationship or comparison between two or more quantities or values. It is typically expressed as a ratio or fraction that compares the part to the whole or the amount of one thing to the amount of another thing.

The two correct methods that Enid can use to test her claim are:

She could calculate the ratio change in calories burned to change in miles jogged for two data points and compare the results to the same ratio with two other data points.

This method involves calculating the ratio of the change in calories burned to the change in distance jogged for two pairs of data points, and then comparing the results to see if they are the same. If they are the same, it would support Enid's claim that the distance she jogs and the number of calories she burns are in a proportional relationship.

She could plot the data on a coordinate plane and see if a straight line starting at (0, 0) passes through all the data points.

This method involves graphing the data points on a coordinate plane and checking if they form a straight line that passes through the origin (0, 0).

Therefore, If the points lie on a straight line passing through the origin, it would support Enid's claim that the distance she jogs and the number of calories she burns are in a proportional relationship.

what is speed of a bullet?

Answers

The speed of the bullet is 1000 m/s when A 10 kg gun recoils with a speed of 0.1 m/s after it fires a 0.001 kg bullet.

As we know that here gun + bullet system is isolated from all other external force systems

so here the momentum of the system is always conserved

so we will say

m₁v₁i + m₂v₂i = m₁v₁f + m₂v₂f

here we know that

v₁i = v₂i = 0

m₁ = 10kg

m₂ = 0.001kg

v₁f = 0.1m/s

now we will have

3. You purchase a car using a $30,000 loan with a 6% simple interest rate.
(a) Suppose you pay the loan off after 6 years. How much interest do you pay on your loan? Show your work.
(b) Suppose you pay the loan off after 3 years. How much interest do you save by paying the loan off sooner? Show your work.

Answer:

Answers

(1) if the loan is paid off after 6 years, the interest paid on the loan is $10,800. (2) $5,400 in interest will be conserved if the debt is repaid in 3 years as opposed to 6 years.

What, using an illustration, is simple interest?

Simple Interest (S.I.) is a technique for figuring out how much interest will accrue on a specific initial sum of money at a certain rate of interest. For instance, if someone borrows Rs. 5000 at a cost of ten p.a. for 2 years, they will pay S.I. on the loaned money for those two years.

(a) Using the straightforward interest calculation, we can determine the amount of interest paid on the debt if it is repaid after six years:

I = Prt

where P represents the loan's capital, r represents the interest rate, and t represents the quantity of time (in years).

P is $30 000, r is 6%, and t is 6 years in this example. With these numbers entered into the algorithm, we obtain:

I = 30,000 * 0.06 * 6 = $10,800

Therefore, if the loan is paid off after 6 years, the interest paid on the loan is $10,800.

(b) To calculate the interest saved by paying off the loan after 3 years instead of 6 years, we can calculate the interest paid in both scenarios and then subtract the interest paid at 3 years from the interest paid at 6 years.

If the loan is paid off after 3 years, the total interest paid can be calculated using the same formula as before:

I = 30,000 * 0.06 * 3 = $5,400

By deducting the interest costs at 3 years from of the interest charged at 6 years, we can determine the amount of interest that would have been paid had the debt been repaid after 3 years:

Interest saved = Interest paid at 6 years - Interest paid at 3 years

= 10,800 - 5,400

= $5,400

Therefore, $5,400 in interest will be conserved if the debt is repaid in 3 years as opposed to 6 years.

f. What is the ratio of the area of Receiver B to the area of Net Area?
g. Are Receiver B and Net Area similar rectangles?
h. The area of Server A is increased by what percent to get the area of Net Area?

Answers

The percentage increase in the area of Server A to get the area of the Net Area is 460%.

What is area ?

Area is a measure of the amount of surface a two-dimensional shape or figure occupies. It is usually measured in square units, such as square meters (m²), square feet (ft²), or square centimeters (cm²).

a. To find the actual length of the court, we can use the given scale of 1 inch representing 8 feet. From the drawing, the length of the court is approximately 10.5 inches. Therefore, the actual length of the court is:

Actual length = 10.5 inches x 8 feet/inch = 84 feet

b. Receiver A has a length of approximately 2.5 inches and a width of approximately 1 inch. Therefore, the actual dimensions of Receiver A are:

Actual length = 2.5 inches x 8 feet/inch = 20 feet

Actual width = 1 inch x 8 feet/inch = 8 feet

c. The Net Area has a length of approximately 3.5 inches and a width of approximately 2 inches. Therefore, the actual dimensions of the Net Area are:

Actual length = 3.5 inches x 8 feet/inch = 28 feet

Actual width = 2 inches x 8 feet/inch = 16 feet

d. To find the percentage of the area of Server B to the area of Server A, we need to calculate the area of each server. From the drawing, Server A has an area of approximately 2.5 inches x 0.5 inches = 1.25 square inches, and Server B has an area of approximately 1 inch x 1 inch = 1 square inch. Therefore, the percentage of the area of Server B to the area of Server A is:

(Area of Server B / Area of Server A) x 100%

= (1 square inch / 1.25 square inches) x 100%

= 80%

e. The perimeter of Receiver B is approximately (1 inch + 2.5 inches + 1 inch + 2.5 inches) = 7 inches, and the perimeter of the Net Area is approximately (3.5 inches + 2 inches + 3.5 inches + 2 inches) = 11 inches. Therefore, the ratio of the perimeter of Receiver B to the perimeter of Net Area is:

Perimeter of Receiver B / Perimeter of Net Area

= 7 inches / 11 inches

= 7/11

f. The area of Receiver B is approximately 2.5 inches x 2.5 inches = 6.25 square inches, and the area of the Net Area is approximately 3.5 inches x 2 inches = 7 square inches. Therefore, the ratio of the area of Receiver B to the area of Net Area is:

Area of Receiver B / Area of Net Area

= 6.25 square inches / 7 square inches

= 0.893

g. Receiver B and Net Area are not similar rectangles, as they have different dimensions.

h. To find the percentage increase in the area of Server A to get the area of the Net Area, we can calculate the area of Server A and the Net Area, and then find the percentage increase. From the drawing, Server A has an area of approximately 1.25 square inches, and the Net Area has an area of approximately 7 square inches. Therefore, the percentage increase in the area of Server A to get the area of the Net Area is:

[(Area of Net Area - Area of Server A) / Area of Server A] x 100%

= [(7 square inches - 1.25 square inches) / 1.25 square inches] x 100%

= 460%

Therefore, The percentage increase in the area of Server A to get the area of the Net Area is 460%.

What is an equation of the line that passes through the points (-4, -2) and (-6, -5)?

Answers

Answer:

Step-by-step explanation:

To find the equation of a line that passes through two given points, we can use the point-slope form of the equation of a line. The point-slope form is:

y - y1 = m(x - x1)

where m is the slope of the line, (x1, y1) is a point on the line, and (x, y) are the coordinates of any other point on the line.

To use this formula, we first need to find the slope of the line that passes through the two given points (-4, -2) and (-6, -5). The slope, denoted by m, is given by the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) = (-4, -2) and (x2, y2) = (-6, -5). Substituting these values, we get:

m = (-5 - (-2)) / (-6 - (-4))

= (-5 + 2) / (-6 + 4)

= -3 / -2

= 3/2

So, the slope of the line is 3/2.

Now, we can choose either of the two given points and use it with the slope to write the equation of the line. Let's use the first point, (-4, -2). Substituting the values of x1, y1, and m in the point-slope formula, we get:

y - (-2) = (3/2)(x - (-4))

Simplifying the right side of the equation, we get:

y + 2 = (3/2)(x + 4)

Expanding the right side, we get:

y + 2 = (3/2)x + 6

Subtracting 2 from both sides, we get:

y = (3/2)x + 4

So, the equation of the line that passes through the points (-4, -2) and (-6, -5) is:

y = (3/2)x + 4

Answers

Answer: 13

Step-by-step explanation:

the Price of each rose will be $6.

What is ratio?

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given,  Masha buys three roses she will have 7 dollars left.

Let's assume the cost of one rose is "x" dollars.

From the first piece of information, we know that if Masha buys three roses, she will have 7 dollars left.

This can be expressed as:

3x + 7 = Masha's initial amount of money

From the second piece of information, we know that Masha needs to borrow 11 dollars to buy nine roses.

This means that the cost of nine roses is:

9x - 11 = Masha's initial amount of money

Since we know that both expressions represent Masha's initial amount of money, we can set them equal to each other:

3x + 7 = 9x - 11

Subtracting 3x from both sides, we get:

7 = 6x - 11

6x = 18

x =3

Therefore, the Price of each rose will be $6.

Answers

Answer:

The correct answer is B. 60 and 64. When y is directly proportional to x, it means that the ratio of y to x remains constant. In this case, when x=6, y=36, which means that the ratio of y to x is 36/6. Since the ratio is constant, we can use that ratio to find the values of y when x=8 and x=10. When x=8, y = (36/6)x8 = 60 and when x=10, y = (36/6)x10 = 64.

The population of a country is growing by 1. 5% per year. A census taken in 1999 showed a population of 9,800,000. Assume the country's population growth remains constant. What will the population be in 2009?

Answers

Population growth is usually an exponential equation. By forming and solving an exponential equation the population in 2009 will be 11,373,300.08

The exponential equation for population growth is,

P = P₀ ( 1+r)ⁿ

P₀ is the initial population, r is the rate and n is the time.

Here r = 1.5% = 1.5/100 = 0.015

n is 10 years and P₀ is 9800000

Substituting the values in equation,

P = 9800000 ( 1+0.015)¹⁰

     = 9800000 × 1.160 = 11,373,300.08

So with the growth rate of 1.5% over 10 years, the population will grow and reach 11,373,300.08.

Answers

Using Poisson distribution, the probability mass function is approximately 4.2%

What is the probability that a randomly selected car passing through the toll booth during the morning commute has 4 occupants

To solve the problem, we can use the Poisson distribution since we are interested in the probability of a certain number of events (in this case, cars with 4 occupants) occurring in a given time period (morning commute).

The Poisson probability mass function is given by:

P(X = k) = (e^(-λ) * λ^k) / k!

where X is the random variable (number of cars with 4 occupants), λ is the mean (average) number of occurrences in the given time period (morning commute), and k is the number of occurrences we are interested in (k = 4 in this case).

Since the average number of non-driver passengers per car is 0.52, we can assume that the average number of total occupants (including the driver) is 1.52. Therefore, the mean (average) number of cars with 4 occupants in a given time period can be calculated as:

λ = (1.52)^4 * e^(-1.52) / 4!

Using a calculator, we get λ ≈ 0.0331.

Now we can plug in the values of λ and k into the Poisson probability mass function:

P(X = 4) = (e^(-0.0331) * (0.0331)^4) / 4!

Using a calculator, we get P(X = 4) ≈ 0.042

Therefore, the probability that a randomly selected car passing through the toll booth during the morning commute has 4 occupants (the driver and 3 passengers) is approximately 0.042 or 4.2%.

Peggy has 8 quarters and 2 nickels

Let's call q the number of quarters and n the number of nickels.

If Peggy has four times as many quarters as nickels, we can write the following equation:

q = 4n

Then, each quarter has a value of 0.25 dollars and each nickel has a value of 0.05 dollars, so

0.25q + 0.05n = 2.10

Because she had $2.10. Now, we can replace the first equation on the second one

0.25(4n) + 0.05n = 2.10

1n + 0.05n = 2.10

Finally, we can multiply both sides by 100, so

100n + 0.05(100)n + 2.10(100)

100n + 5n = 210

Therefore, the equation that can be used to solve the problem is

5n + 100n = 210

Now, we can solve the equation for n

105n = 210

105n/105 = 210/105

n = 2

Then, q is equal to

q = 4n

q = 4(2)

q = 8

Similarly, the Euclidean distance between two points, (x1, y1, z1) and (x2, y2, z2), in a three-dimensional space is given by the formula:

d = √[[tex](x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2][/tex]

The distance between two points can be positive or zero, but it cannot be negative. Distance is an important concept in many areas of mathematics and science, such as geometry, physics, and engineering. It is also used in real-life applications, such as navigation, transportation, and sports.

There are other measures of distance used in different contexts, such as Manhattan distance or taxicab distance, which measure the distance between two points by the sum of the absolute differences of their coordinates, rather than the square of the differences as in Euclidean distance. Additionally, distance can be defined in different ways for objects other than points, such as for the distance between two lines or two planes in geometry.

To determine the distance the submarine needs to travel to get to the destination, we need to calculate the vertical distance between the submarine and the destination point.

The vertical distance is the difference between the destination point and the submarine's current position:

Distance = Destination Point - Submarine's Position

Distance = (-10.5 ft) - (4.5 ft)

Distance = -15 ft

Therefore, the distance the submarine needs to travel to get to the destination is 15 feet.

The speed of sound in air is about 1225 kilometers per hour. The speed of sound in seawater is about 1520 meters per second. Does sound travel faster in air or in seawater? How many times faster?

Answers

The speed of sound in seawater is around 4.46 times faster than speed of sound in air.

Conversion of units:

Unit conversion is the process of converting the measurement of a given quantity between different units, often by multiplicative conversion factors that modify the value of the measured quantity without altering

its effects.

Speed of Sound:

Speed of sound, the rate at which sound waves move through various substances. Modern estimates of the speed of sound, specifically for dry air at a temperature of 0 °C (32 °F), are 331.29 metres (1,086.9 feet) per second.

Now in the given question ,

speed of sound in air is 1225 km/hr.

speed of sound in sea water = 1520 m/s.

To compare the speed of sound we have to make them in same unit form.

So , we will change speed of sound in air in m/s.

speed of sound in air = 1225 km/hr

                                     [tex]=\frac{1225*1000}{60*60} m/s\\\\=\frac{12250}{36} m/s\\\\=340.28m/s[/tex]

So , it can be clearly seen that speed of sound in air is less than speed of sound in  seawater.

Also , the speed of sound in seawater is around 4.46 times faster than speed of sound in air.

A man got 80 tons of apples from his farms and sold it at Rs 1800/40kg. calculate the Ushr he has to pay

Answers

The man has to pay Rs 9,000 as Ushr for 80 tons of apples

What is Multiplication?

Multiplication is a basic arithmetic operation that involves combining equal groups or adding the same number repeatedly. It is represented using the multiplication symbol × or the asterisk *.

To calculate the Ushr, we first need to convert the weight of the apples from tons to kilograms, since the price is given in rupees per 40 kg:

80 tons = 80,000 kg

Next, we need to find out how many 40-kg units are in 80,000 kg:

80,000 kg / 40 kg = 2,000 units

Therefore, the man sold his apples in 2,000 units of 40 kg each. To find the total revenue frm the sale, we need to multiply the price per unit by the number of units:

2,000 units x Rs 1800/40kg = Rs 90,000

The Ushr is typically calculated as one-tenth of the total revenue, so in this case:

Ushr = 1/10 x Rs 90,000 = Rs 9,000

Therefore, the man has to pay Rs 9,000 as Ushr.

p − 266 = 399; p = 665 pages
p over 266 equals 2; p = 532 pages
p + 266 = 399; p = 133 pages
133p = 266; p = 2 pages

5√180 +4√/18 - √50.
Simply

Answers

Answer:

30√5 + 7√2

Step-by-step explanation:

To simplify this expression, we can first use the fact that the square root of a product is equal to the product of the square roots. We can also simplify any perfect squares under the square root sign.

5√180 + 4√18 - √50

= 5√(36 × 5) + 4√(9 × 2) - √(25 × 2)

= 5√36 × √5 + 4√9 × √2 - √25 × √2

= 5 × 6√5 + 4 × 3√2 - 5√2

= 30√5 + 12√2 - 5√2

= 30√5 + 7√2

Therefore, the simplified form of the expression is [30√5 + 7√2.]

The area of a rectangular room is 750 square feet. The width of the room is 5 feet less than the length of the room. Which equations can be used to solve for y, the length of the room? Select three options.

y(y + 5) = 750

y2 – 5y = 750

750 – y(y – 5) = 0

y(y – 5) + 750 = 0

(y + 25)(y – 30) = 0

Answers

Answer:

y^2 - 5y = 750

Step-by-step explanation:

If length = y

then width = y - 5

Area = length x width

= y(y-5) = 750

Or, y^2 - 5y = 750

This equation can be further solved as follows:

y^2 - 5y - 750 = 0

Or, y^2 - 30y + 25y - 750 = 0

Or, y(y - 30) + 25(y - 30) = 0

Or, (y + 25)(y-30) = 0

So, there are two possibilities:

If (y + 25) = 0

then y = -25

but value of length cannot be negative,

Let us look at second possibility

If (y - 30) = 0

then y = 30

So, length = 30 feet

Check Answer:

Length = 30 feet

so, width = 30 - 5 = 25 feet

so, area  = 30 x 25 = 750 square feet

Henry deposited his savings in the neighborhood bank. The bank paid an interest of 8% compounded quarterly. How much had Henry deposited if he received $13,299. 23 after 5 years? Round your answer to the nearest dollar

Answers

Henry had deposited approximately $8,000.32 if he received $13,299.23 after 5 years. Rounded to the nearest dollar, the answer is $8,000.To solve this problem, we can use the formula for compound interest:

[tex]$$ A = P \left(1 + \frac{r}{n}\right)^{nt} $$[/tex]

where A is the amount after t years, P is the principal (the amount deposited), r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

In this case, we have:

A = $13,299.23

r = 0.08 (8%)

n = 4 (quarterly compounding)

t = 5 years

We can rearrange the formula to solve for P:

[tex]P = \frac{A}{(1 + \frac{r}{n})^(nt) }[/tex]

Plugging in the values, we get:

[tex]P = \frac{ $13,299.23}{(1 + \frac{0.08}{4} ) ^ {(4*5)} }[/tex]

P ≈ $8,000.32

Therefore, Henry had deposited approximately $8,000.32 if he received $13,299.23 after 5 years. Rounded to the nearest dollar, the answer is $8,000.
