A right square pyramid has a slant height of 25 feet, and the length of a side of the base is 14 feet. What is the height of the

Tanzania [10]

Answer: $24\ ft$

Step-by-step explanation:

Given

The slant height of the square pyramid is $l=25\ ft$

The length of the side of the base is $a=14\ ft$

for the square pyramid, height is given by

$\Rightarrow h=\sqrt{l^2-r^2}\quad \quad [\text{where r=}\frac{a}{2}]\\\Rightarrow h=\sqrt{25^2-7^2}\\\Rightarrow h=\sqrt{625-49}\\\Rightarrow h=\sqrt{576}\\\Rightarrow h=24\ ft$

Thus, the height of the prism is $24\ ft$

How much interest would be earned on $3,700 in one year if it is invested at 4%?

malfutka [58]

I'd say $148 because you convert the percent into a decimal so
4%= 0.04

Then you multiply $3,700•0.04 = $148

So I'd say the interest earned on $3,700 in one year would be $148
