we know that
The volume of the triangular pyramid is equal to
where
B is the area of the triangular base
h is the height of the pyramid
In this problem we have
substitute in the formula
C. 17
Why:
Divide 100 by 6, round the answer and you should get 17
If Simone has 20 bills, then:
1/5 of 20 = 4 [hundreds]
1/4 of 20 = 5 [fifites]
1/10 of 20 = 2 [$20s]
4 * 100 + 5 * 50 + 2 * 20 = 400 + 250 + 40 = 690 [out of $780]
4 + 5 + 2 = 11 [out of 20 bills]
So now we can easily find out she had 9 bills of tens - because 20 - 11 = 9 or because (780 - 690) ÷ 10 = 90 ÷ 10 = 9.
