Answer:
We should add 2.4 quarts of pure orange juice to 3.6 quarts 10% orange juice to make 6 quarts of 40% orange juice.
Explanation:
Let p represent number of quarts of pure orange juice and q represent number of quarts of 10% orange juice.
We have total quarts required = 6
So, p+q =6 --------------------equation 1
The orange content of 6 quarts = 40 % = 6 x 40/100 = 2.4 quarts.
Orange content in p pure juice = p quarts.
Orange content in q, 10% juice = q x 10/100 = 0.1 q quarts
So we have, p + 0.1 q = 2.4 --------------------equation 2
Equation 1 - Equation 2 gives
0.9 q = 6 -2.4
q = 3.6 quarts
p + 3.6 = 6
p = 2.4 quarts
So we should add 2.4 quarts of pure orange juice to 3.6 quarts 10% orange juice to make 6 quarts of 40% orange juice.
Answer: PQ = 18
Step-by-step explanation:
You would divide 21/14 to see what the size difference in the triangles is to get 1.5. 1.5x12=18
X - 6 1/3 < = 1 1/2 ....turn to improper fractions
x - 19/3 < = 3/2 ....add 19/3 to both sides
x < = 3/2 + 19/3 ...common denominator is 6
x < = 9/6 + 38/6
x < = 47/6 = 7 5/6....first answer choice
