Answer:

z = $\frac{50}{3}$

Step-by-step explanation:

The ratio of corresponding sides are equal, that is

$\frac{z}{10}$ = $\frac{20}{12}$ ( cross- multiply )

12z = 200 ( divide both sides by 12 )

z = $\frac{200}{12}$ = $\frac{50}{3}$

kobusy [5.1K]

Answer:

14.25 hours

Step-by-step explanation:

Four tires = 3/4 of an hour

=> 1 car = 3/4 of an hour

=> 19 cars = ?

=> If 1 = 3/4

=> 19 = 3/4 x 19

=> 57/4

=> 14.25 hours

So, it would take 14.25 hours for 19 car's tires to be changed.

Jack was planting a tree. He was to dig a hole that was 3 feet deep for every 5 feet of tree height. How deep should he dig the hole for a tree that is 17feet high.

Calculations

$\frac{DEEP}{HIEGHT}$

Cross multiplication

$\frac{3 DEEP}{5 HIEGHT}$ = $\frac{x}{13}$

5x = 2 x 13

Divide by 5 to isolate x

$\frac{5x}{5}$ = $\frac{51}{5}$

x = 10.2

Answer = 10.2
