1. The amount of Kelly's paycheck varies directly with the number of hours
she works. Kelly receives $139.80 for 12 hours of work.

(a) Write a direct variation equation that relates the amount of Kelly's paycheck, y, to the number of hours, x,
that Kelly works.

(b) Use the equation to find the amount of Kelly's paycheck when she works 40 hours.

Answers

Answer 1

Answer:

Step-by-step explanation:

y = kx ; k = [tex]\frac{y}{x}[/tex]

~~~~~~~~~~

(a). 139.8 = k × 12

k = 139.8 ÷ 12 = 11.65 ⇒ Kelly earns $11.65 per hour

y = 11.65x

(b). y = 11.65 × 40 = 466

Kelly's paycheck when she works 40 hours is $466.00

Answers

Answer:

174

Step-by-step explanation:

(10)+(24)+10+123+7

=174

Answer:

174

Step-by-step explanation:

5⋅2+4⋅6+10+123+(8)−1

Multiply 5 and 2 to get 10. Multiply 4 and 6 = 24.

10+24+10+123+8−1

Add 10 and 24 =34.

34+10+123+8−1

Add 34 and 10 =44.

44+123+8−1

Add 44 and 123 =167.

167+8−1

Add 167 and 8 =175.

175−1

Subtract 1 from 175 = 174.

Answers

Answer: 6
Pam can fill 6 bottles of apple juice.

The number of bottles she can fill if, Pam makes 5 liters of apple juice. She saves 0.5 liters of apples for dinner and puts the rest in bottles is 6.

What is multiplication?

One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.

Given:

Pam makes 5 liters of apple juice. She saves 0.5 liters of apples for dinner and puts the rest in bottles,

If each bottle holds 0.75 liters,

Calculate the amount of juice left as shown below,

The amount of juice left = 5 - 0.5

The amount of juice left = 4.5 liter,

Calculate the number of bottles as shown below,

The number of bottles = The amount of juice left / juice held by each bottle

The number of bottle = 4.5 / 0.75

The number of bottles = 6

Mr. aba builds a circular patio with a diameter of 12 feet he covers the patio with paving stones the cost of the paving stones is $10.50 per square foot to the nearest dollar how much do the paving stones cost?

Answers

1.) Find the area of the circle:
• Formula: A=pi•r^2

- To find the area of a circle, we need to have the radius, and since the diameter is 2x the length of the radius, the radius is 1/2 of the diameter.

Finding the radius: r=d/2

r=12/2

r = 6.

- Now that we know that r=6, we can substitute it into the formula:
• A=pi•r^2

A=pi•(6)^2

A=113.097

- The area of the circle is 113.097ft.^2. We know that a square foot is $10.50. So, we have 113.097 square feet at $10.50/sq. foot. This means that we will add $10.50 113.097 times. Therefore:

113.097 • 10.50 = 1,187.518

So, total, it will cost $1,187.518

The cost of a baguette and a cup of hot chocolate is $1.45. The cost of 2 baguettes and a cup of hot chocolate is $2.10. What is the cost of one cup of hot chocolate?

Answers

Answer:

It is $0.8

Step-by-step explanation:

First find out the value of one baguette.

They just added one more baguette. So the amount left after subtracting them both will be the cost of 1 baguette.

2.10 - 1.45 = 0.65

Now, subtract the 1st cost with the cost of 1 baguette.

1.45 - 0.65 = $0.8

For each 16 unit increase in x, you get a 6 unit increase in y.

So, you can approach this with the idea of slope (change in y over change in x) to have a slope of 6/16 or 3/8.

y = 3/8 x

This checks out with all of those values.

The system is inconsistent because the slopes are the same and the lines are different.

A linear equation is of the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Given the following system of equations:

y = 6x + 2     (1)

y = 6x + 1      (2)

We can see that both equations have the same slope of 6 but have different y intercepts.

Hence the system is inconsistent because the slopes are the same and the lines are different.
