Answer:
4.5 ft^3
Step-by-step explanation:
note to convert 18 in. to feet = 1.5 feet
divide the length value by 12
Answer:
20.4 ft
Step-by-step explanation:
Since they're similar triangles (same shape, but not necessarily the same size), then you can set them up as fractions to find the missing measure.
6/9.7 = ?/33
A quick way to do use this setup is to multiply 33 by 6, then divide by 9.7.
This gives you 20.4 ft
-5(r - 6) + 3(-8 + 8r) = -32
STEP 1: Simplify both sides of the equation.

STEP 2: Subtract 6 from both sides.

STEP 3: Divide both sides by 19.
19r/19 = -38/19
r = -2
