The flag pole is 20 feet tall with an 8 foot shadow.

The tree is X feet tall with a 12 foot shadow.

20/8 = X/12

Cross multiply:

20 * 12 / 8*X

240 = 8x

Divide both sides by 8:

x = 240/8

x = 30

The tree is 30 feet tall.

If 1800ml of a juice drink is 15% grape juice, how much grape juice should be added to make a drink that is 20% grape juice?
Svetach [21]

Answer:

  112.5 mL

Step-by-step explanation:

Let x represent the amount of grape juice to add. Then the total amount of grape juice in the mix is ...

  0.15(1800) +x = 0.20(1800+x)

  270 +x = 360 + 0.2x . . . . . . eliminate parentheses

  0.8x = 90 . . . . . . . . . . . . . . . subtract 270+0.2x

  x = 90/0.8 = 112.5 . . . . . . . . divide by the coefficient of x

112 mL of grape juice should be added to make a mix that is 20% grape juice.
