Write and solve a proportion to answer the question. 36 is 0.9% of what number w? =0.9100

pickupchik [31]

Answer:

Step-by-step explanation:

The question can be written out like this:

36 = 0.009x

Multiply both sides by 1,000:

9x = 36,000

Divide both sides by 9:

x = 4,000

a recipe uses 1 1/4 cups of milk to make 10 servings. if the same amount of milk is used for each serving, how many servings can

Anestetic [448]

Answer:

128 servings can be made using 1 gallon of milk.

Step-by-step explanation:

Given that:

$1\frac{1}{4}$ cups of milk make 10 servings

$1\frac{1}{4}$ can also be written as 1.25

Ratio of cups of milk to servings = 1.25 : 10

1 gallon = 16 cups

Let,

x be the number of servings made from 1 gallon

Ratio of cups of milk to servings = 16 : x

This is a direct proportion

1.25 : 10 :: 16 : x

Product of mean = Product of extreme

10*16 = 1.25x

160 = 1.25x

1.25x=160

Dividing both sides by 1.25

$\frac{1.25x}{1.25}=\frac{160}{1.25}\\x=128$

Hence,

128 servings can be made using 1 gallon of milk.

I assume you are calculating the total area to be painted.
Then 3 x 8.3 x 7.5 = 186.75 sq. ft.
