Answer:
9 ft
Step-by-step explanation:
Let's begin with the formula for the volume of a square pyramid. If s is the base length, then the area of the base is s^2. The volume of the pyramid is then V = (1/3)(base area)(height). We know the volume and the base length (s), and want to find the height. Solving V = (1/3)(base area)(height)
for height, we get:
3V = (base area)(height), or
3V
---------------- = height
base area
Substituting 75 ft^3 for V and (5 ft)^2 for base area, we get:
3(75 ft^3) 9 ft
height = ------------------ = ----------------- = 9 ft
25 ft^2 1

Question:
Write an algebraic expression for how many miles Mr.Stein drove.
Answer:
(70 - y) miles
Step-by-step explanation:
Given
Distance to business meeting from office = 70 miles
Mr. Smith drove the first y miles
Let x = the remains distance driven by Mr. Stein
x + y = 70 ---- Make x the subject of formula
x = 70 - y
So, the expression is (70 - y) miles
