All sides of a cube are the same.
So to calculate the volume, you only need to know the measure of one side.
The formula for the volume of a cube is the length of the edge to the power of 3.
The measure of the known edge is 9, so the formula for volume would be 9^3.
9^3 is 9 • 9 • 9, which is 9 times 9 times 9.
9 • 9 = 81
81 • 9 = 729
The volume of this cube is 729 cubic feet.
There must be a typo in the answer choices because 729 cubic feet is the answer for the volume of the cube, even though it's not listed.
Answer:
x = 13
Step-by-step explanation:
ΔRST≈ΔYSZ
therefore:
RT/ST = YZ/SZ
(3x-7)/40 = (2x+2)/35
cross-multiply:
40(2x+2) = 35(3x-7)
80x+80 = 105x-245
80 = 25x-245
325 = 25x
325/25 = x
x = 13
Answer:
b=−5x+y
Step-by-step explanation:
Let's solve for b.
y=5x+b
Step 1: Flip the equation.
b+5x=y
Step 2: Add -5x to both sides.
b+5x+−5x=y+−5x
b=−5x+y
Answer:
6^5 * 9^5
Step-by-step explanation:
( 6*9) ^5
We know that ( ab) ^c = a^ c* b^c
6^5 * 9^5
