Michelle wishes to build a square pool in her backyard. She has saved enough to build a pool with the area of 150 square feet. W
frozen [14]
When it comes to finding the area of spaces, you must determine its shape. In this case, the shape of the pool is a square. From there, we will use the formula to find the area of a square.

Area = (side)^2

Since the square of the square's side is its total area, then if vice versa, we have to find the square root of the area to find the length. Thus,

Length = √150 = 5√6 = 12.25 ft

What is the point-slope form given the following slope and a point on the line? m = 3/7 , (7, -4)
GarryVolchara [31]

Answer:

The equation is y = (3/7)x - 7.

Step-by-step explanation:

Given that the point slope form of an equation is y = mx + b where m represents the gradient and b is the y-intercept. Then, you have to substitute the following values into the equation :

y = mx + b

let \: m =  \frac{3}{7} ,x = 7,y =  - 4

- 4 =  \frac{3}{7} (7) + b

- 4 = 3 + b

- 4 - 3 = b

b =  - 7

If Eli showed a 8.9% ROI on his $8000.00 investment, how much was his return on his investment
telo118 [61]
8.9% is equal to 0.089 because a percent is over a 100. So, you can just multiply the ROI by the investment to get:

0.089(8000) = 712

Your answer is: $712.
