Answer:
Step-by-step explanation:
If I have 90 pounds shared between A, B, and C, then in a mathematical equation,
A + B + C = 90
However, we have way too many unknowns.
We are told that the ratio of A to B is 1 to 2, or
and cross multiplying,
2A = B or ![A=\frac{1}{2}B](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7DB)
We are also told that the ratio of B to C is 4 to 3, or
and cross multiplying,
3B = 4C or ![C=\frac{3}{4}B](https://tex.z-dn.net/?f=C%3D%5Cfrac%7B3%7D%7B4%7DB)
Now we have everything in terms of B, so we will rewrite it like that:
, and
and
9B = 360 so
B = 40. If B is 40 and A is half of B, then A is 20.

Answer:
9
Step-by-step explanation:
V=pi (r squared) (h/3)
75pi = 25pi (h/3)
Divide both sides by 25 pi
3= h/3
Multiply both sides by 3
h=9
