Answer:
B. 15 ft^3
Step-by-step explanation:
The volume of a pyramid is given by the formula ...
V = (1/3)Bh
where B represents the area of the base, and h represents the height.
The base is apparently a rectangle, so its area is the product of its length and width:
B = L·W = (4.5 ft)(4 ft) = 18 ft^2
Then the volume is ...
V = (1/3)(18 ft^2)(2.5 ft) = 15 ft^3
15 cubic feet of sand will be needed to fill the base.
Answer:
the answer would be 38 :)
Step-by-step explanation:
24÷3=8
(8)+3+3 to the 3rd power
3×3×3=27
8+3=12 ->12+27=38
hopefully this helps :)
9 3/4 is a mixed number, and to find a percent it has to be a percent of what. 9 3/4 as a percent alone is 975% if that's what they want.
Answer:
x=7
Step-by-step explanation:
To set up for this answer, we need to set it up as an equation: 2x+12=5x-9.
get the xs on one side and the whole numbers on the other.
that leaves you with 21=3x.
divide by 3 on both sides to get the answer of x=7
