Write each rate as a unit rate. $2 for 5 cans of soup.
Len [333]
If you would like to write each rate as a unit rate, you can do this using the following steps:

$2 ... 5 cans of a soup
$1 ... x cans of a soup = ? 

2 * x = 5 * 1
2 * x = 5
x = 5 / 2
x = 2.5 cans of a soup per $1

$2 ... 5 cans of a soup
$x = ? ... 1 can of a soup

2 * 1 = 5 * x
2 = 5 * x
x = 2 / 5 
x = $0.4 per 1 can of a soup

6. Answer:

72.84

Step-by-step explanation:

To find the perimeter of the rectangle, just add the sides together except the one connected to the semicircle

12 + 15 + 15 = 42

The diameter of the semi circle is 12

πr + d = 6 * π + 12 ≈ 30.84

Add them together

42 + 30.85 = 72.84

7. Answer:

78.54

(78.5)

Step-by-step explanation:

The shape is a circle

Radius is 5

Diameter is 10  (diameter is always double of the radius)

π * r^2 = π * 25 cm^2 = 78.54 cm^2

8. Answer:

50.27

Step-by-step explanation:

The shape is a circle

Radius is 4

Diameter is 8  (diameter is always double of the radius)

π * r^2 = π * 16 ft^2 = 50.27 ft^2

(16 = 8 * 2)
