Write and solve a proportion to find the height of the building. i need on finding the height with an understandable confused

Write and solve an equation of ratios:

9 ft          22 ft

=

h               99 ft

This is appropriate because h is greater than 9 ft.

cross-multiplying, we get 

9(99) ft^2 = 22*h*ft

Then h =40.5 ft (which is the height of the building)

Remark

Keep the objects on one side of the proportion and the shadows on the other side. The length of the shadows should be right across from the height of the of the object it represents.

Formula

Sub and Solve

Let the height of the building = x

x/99 = 9/22 Cross multiply.

22x = 9 * 99

22x = 891 Divide by 22

x = 891/22

x = 40.5

The height of the building is 40.5 feet <<<< Answer

11 feet 6 inches and 8 feet 6 inches

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
