First we need to find the square footage of her ceiling, since it's a square just multiply the side by the side: 44•44=1936. Now divide the square feet by how many feet each can can paint: 1936/242=8. Jenny would need exactly 8 cans of paint to paint her ceiling :)
Answer:
A.) b- 9.5 = 26.5
Step-by-step explanation:
because the equation is basically saying that (the og length) - 9.5( the one he cut out) = 26.5 ( which is the remaining wood)
Answer:
x = 65
Step-by-step explanation:
To solve the equation, we write it in radical form:
![5\, \sqrt[3]{x-1} = 20](https://tex.z-dn.net/?f=5%5C%2C%20%5Csqrt%5B3%5D%7Bx-1%7D%20%3D%2020)
Then, we divide both sides by 5 to isolate the root:
![\sqrt[3]{x-1} = \frac{20}{5} \\\sqrt[3]{x-1} =4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx-1%7D%20%3D%20%5Cfrac%7B20%7D%7B5%7D%20%5C%5C%5Csqrt%5B3%5D%7Bx-1%7D%20%3D4)
and next, we raise both sides of the equation to the power 3 so as to free the expression in x from the root:
now we add 1 to both sides to isolate x:
x = 65
When the adding is inside the parentheses it is a horizontal shift to the left.
This affects the x - axis.
So, we take our x coordinate, 4, and subtract 3.
4 - 3 = 1
So, the new point is:
( 1, -8)
