Pepsi [2]3 years ago

The ratio A/r² would represent \pi which is the circumference of a circle divided by its diameter.

You can see this because the area of a circle is \pir² and if you divided that by the radius squared, you are given pi which is the circumference of a circle divided by its diameter.

153 is 0.9% of what number? Tell which equivalent ratios you used to find the solution
Naddik [55]
0.9% / 100% = 0.009
= 9/1000

equivalent ratio:
9/1000 = 153/x

cross multiply
9x = 153,000
x = 153,000/9
x = 17,000

153/17,000 = 0.009

sveticcg [70]

Answer:

28.5 feet

Step-by-step explanation:

A water tower casts a shadow that is 24 foot long. A 9.5 foot tall tree casts a shadow that is 8 foot long. What is the height of the water tower?

The formula is given as:

Height of the tower/Shadow of the tower = Height of the tree/Shadow of the tree

Let the Height of the tower = x

Hence:

x/24 = 9.5/8

Cross Multiply

8x = 24 × 9.5

x = 24 × 9.5/8

x = 28.5 feet

Therefore, the height of the water tower is 28.5 feet
