Answer 1

Answer:

Part A A. 400 sq ft.

Part B A. 509 sq ft

Step-by-step explanation:

Part A

Area of square = side squared

Since all the sides of the square are congruent and the perimeter is 80, then the length of each side is 80/4 = 20

A = 20^2 = 400 sq ft

Part B

C = πd

80 =

80/π = d

r = d/2 = 80/2π = 40/π

A = πr^2 = π(40/π)^2

= 1600π/π^2 = 1600/π = 1600/3.14 = 509 sq ft

Answer:

y = 27/6

Step-by-step explanation:

3/2x - 6 = -9/2x + 21

12/2x = 27

6x = 27

Since both are y, you know the values are equal to each other.
3/2x - 6 = -9/2x + 21
3/2x = -9/2x + 27
Get rid of fraction (multiply by 2)
3x = -9x + 54
12x = 54, x = 4.5
Plug 4.5 into any equation as x
y = 3/2(4.5) - 6
y = 6.75 - 6 = 0.75

Solution: y = 0.75 or 3/4

Use the following situation for questions #1-10.
Ashley has two jobs: mowing lawns and babysitting. She earns $10 per hour mowing lawns
(x) and $8 per hour babysitting (y). She wants to earn at least $160 per week.
4. What is the x-intercept for the inequality? Show your work!

Answers

Answer:

We have the variables:

x = hours that she mows lawns per week.

y = hours that she babysits per week.

She earns $10 per hour mowing lawns and $8 per hour babysitting.

Then she earns a total of:

x*$10 + y*$8

We also know that she wants to earn at least $160 per week.

Then we have the inequality:

Total weekly earnings ≥ $160

This can be written as:

x*$10 + y*$8 ≥ $160

Now we want to find the x-intercept of the inequality.

The x-intercept is the possible y-values when x = 0 (the x-axis)

Then we just need to set x = 0 and find the possible solutions for y.

0*$10 + y*$8 ≥ $160

y ≥ $160/$8 = 20

y ≥ 20

The x-intercept of the inequality is the set of all the points (0, y) such that:

y ≥ 20
