Answer:
h = 21.6 m
Step-by-step explanation:
*I'm assuming that you need the height. If not, let me know and I'll edit my answer...
The formula for volume of a pyramid is
V = (1/3)Bh where B is the area of the base, and h is the height
We are given V = 8820, and the base is a square with area of 35² = 1225, plug those in and find the height...
8820 = (1/3)(1225)h
26460 = 1225h (multiply both sides by 3 to get rid of the fraction)
26460/1225 = h (divide both sides by 1225 to isolate h)
21.6 = h
Answer:
$50
Step-by-step explanation:
Let x represent the cost of the cell phone.
Since the TV cost 5 times as much as the cell phone, its cost can be represented by 5x.
Since the computer cost 2.5 times as much as the TV, its cost can be represented by 12.5x.
Create an equation to represent the situation, and solve for x:
x + 5x + 12.5x = 925
18.5x = 925
x = 50
So, the cell phone cost $50
