Answer:
20 quarts of 6% butterfat milk and 40 quarts of 3% butterfat milk is used to make 60 quarts of 4% butterfat milk.
Step-by-step explanation:
We are given the following in the question:
Let x quarts of 6% butterfat milk be used and y quarts of 3% butterfat milk be used to make 60 quarts of 4% butterfat milk.
Thus, we can write the equation:

Total amount of 3% butterfat milk = 60
Thus, we can write the equation:

Solving the two equation, we get,

Thus, 20 quarts of 6% butterfat milk and 40 quarts of 3% butterfat milk is used to make 60 quarts of 4% butterfat milk.
Let x be her initial distance from the building, then tan 37 = 130/x
x = 130/tan 37 = 130/0.7536 = 172.5 feet
Let y be her distance from the building after moving forward, then
tan 40 = 130/y
y = 130/tan 40 = 130/0.8391 = 154.9
After moving forward, she is 172.5 - 154.9 = 17.6 ft closer.
Answer:
16 nickels and 20 dimes
Step-by-step explanation:
16x5=80
20x10=200
80+200=280
280 cents = $2.80
there are 5 1/5 in an hour
so multiply 1/2 by 5
1/2 = 0.5
0.5 *5 = 2.5 miles in 1 hour
