One canned juice drink is 25% orange juice; another is 10% orange juice. How many liters of each should be mixed together in
order to get 15L that is 21% orange juice?
1 answer:
11 liters of 25% orange juice, 4 liters of 10% orange juice:
1' let x to be 25% orange juice and y be 10% orange juice
2' .25x+.10y=(15).21
3' x+y=15
4' 2.5x+y=31.5 divide all sides by 10
5' -x-y=-15 multiply all sides by -1
6' 1.5x=16.5
7' x=11
8' y=15-11=4
so 11 and 4 are the answers.

Volume of cylinder = πR².H
Volume Sphere: =4/3πR³
Volume of cylinder = Volume Sphere (given), then:
πR².H = 4/3πR³
Simplify==> R².H = (4/3)R³==> H = (4/3)R===> R=3H/4
