Answer:
Part a) ![160\ gallons](https://tex.z-dn.net/?f=160%5C%20gallons)
Part b) ![480\ gallons](https://tex.z-dn.net/?f=480%5C%20gallons)
Step-by-step explanation:
Part a) How many gallons of water will be in the pool after 20 minutes?
we know that
Using proportion
![\frac{40}{5}\frac{gallons}{minutes}=\frac{x}{20}\frac{gallons}{minutes} \\ \\x=40*20/5\\ \\x=160\ gallons](https://tex.z-dn.net/?f=%5Cfrac%7B40%7D%7B5%7D%5Cfrac%7Bgallons%7D%7Bminutes%7D%3D%5Cfrac%7Bx%7D%7B20%7D%5Cfrac%7Bgallons%7D%7Bminutes%7D%20%5C%5C%20%5C%5Cx%3D40%2A20%2F5%5C%5C%20%5C%5Cx%3D160%5C%20gallons)
Part b) How many gallons of water will be in the pool after 1 hour
we know that
1 hour = 60 minutes
Using proportion
![\frac{40}{5}\frac{gallons}{minutes}=\frac{x}{60}\frac{gallons}{minutes} \\ \\x=40*60/5\\ \\x=480\ gallons](https://tex.z-dn.net/?f=%5Cfrac%7B40%7D%7B5%7D%5Cfrac%7Bgallons%7D%7Bminutes%7D%3D%5Cfrac%7Bx%7D%7B60%7D%5Cfrac%7Bgallons%7D%7Bminutes%7D%20%5C%5C%20%5C%5Cx%3D40%2A60%2F5%5C%5C%20%5C%5Cx%3D480%5C%20gallons)
so if you take away 1/4 from 3/4 you will get 2/4
3/4 - 1/4 = 2/4 or 1/2
so the male elephant weights 1/2 a ton more than the female

Srry If Im wrng but Hope this helped :)
This is a typical mixture problem where using a table is the best thing.
pints juice % juice = total % juice
juice A x .70 = .70x
juice B 60-x .95 = .95(60-x)
total 60 .75 = 60(.75)
The last row gives you a total that you need to use, so do that multiplication to get 45. You now to need to add the last columns together for rows 1 and 2 and set them equal to 45: .7x +.95(60-x) = 45. When you do that math, you'll get that x = 48. This means that you need 48 pints of juice A and 60-48 pints of juice B, which is 12 pints.
