Find how many quarts of 5% butterfat milk and 2% butterfat milk should be mixed to yield 30 quarts of 3% butterfat milk

10 quarts of 5% with 20 quarts of 2% buttermilk

Step-by-step explanation:

x + y = 30  where x = volume of 5% and y = volume of 3%

0.05x + 0.02x = 0.03(x + y)

0.02x - 0.01y = 0   Multiply   through by 100

2x - y = 0

Add the above equation to the first equation:-

3x =  30

x = 10

so y = 30-10 = 20

step-by-step explanation:

infinity is the answer

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
