Joy is making a fruit salad. For every 2 cups of blueberries that Joy uses in the fruit salad, she uses 3 cups of strawberries.

Igoryamba

Joy will need to use 9 cups of strawberries for 6 cups of blueberries.

Step-by-step explanation:

Given,

Cups of blueberries used for 3 cups of strawberry = 2

Ratio of cups of blueberry to strawberry = 2:3

Joy wants to use 6 cups of blueberries.

Let,

x be the cups of strawberry for 6 cups of blueberries.

Ratio of cups of blueberries to strawberries = 6:x

Using proportion;

Ratio of cups of blueberry to strawberry :: Ratio of cups of blueberries to strawberries

$2:3::6:x$

Product of extreme = Product of mean

$2*x=3*6\\2x=18$

Dividing both sides by 2

$\frac{2x}{2}=\frac{18}{2}\\x=9$

Joy will need to use 9 cups of strawberries for 6 cups of blueberries.

Which numbers are a distance of 3.2 units from −4 on a number line? A number line with increments of .5 with a range of 0 to neg

yulyashka [42]

Answer: The numbers on a distance of 3.2 units from −4 on a number line are -7.2 and - 0.8 .

Step-by-step explanation:

The numbers on a number line are from - infinity to + infinity whose center is at 0.Om left sides of 0 , there are negative integers and on the right side there are positive integers.

So, The numbers on a distance of 3.2 units from −4 on a number line are

-4 - 3.2 and -4+3.2

= - (4+3.2) and - (4-3.2)

= -7.2 and - 0.8

Hence, the numbers on a distance of 3.2 units from −4 on a number line are -7.2 and - 0.8 .
