The ratio of two numbers is 7 to 5. The sum of the numbers is 24. What are the numbers?

Kipish [7]

Answer:

14 and 10

Step-by-step explanation:

The ratio of the 2 numbers = 7x : 5x

The sum of the 2 numbers is 24, hence

7x + 5x = 24

12x = 24 ( divide both sides by 12 )

x = 2

7x = 7 × 2 = 14

5x = 5 × 2 = 10

Thus the numbers are 14 and 10

A new park was designed to contain two circular gardens. Garden A has a diameter of 50 m, and garden B has a diameter of 70 m. T

Nastasia [14]

Answer:

$5,811.95\ m^2$ of fabric.

Step-by-step explanation:

-The amount of fabric needed is equivalent to the area of the two gardens.

-We calculate the combined areas as:

$A=A_s+A_b\\\\=\pi r^2+\pi R^2\\\\=\pi(25^2+35^2)\\\\=1850\pi \ m^2\\\\=5811.95\ m^2$

Hence, 5811.95 sq meters of fabric will be needed to cover the area of both gardens.
