Answer:
40
Step-by-step explanation:
32/4=8
8 is 2x 4 so multiply 5x2=10
now multiply 10x4
Linda should use ...
15 gallons of 80% juice
5 gallons of 60% juice
_____
Let g represent the number of gallons of 80% juice needed. Then (20-g) is the number of gallons of 60% juice Linda will use. The amount of juice in the mixture can be written as
0.80g +0.60(20 -g) = 0.75×20
0.20g = 20(0.75 -0.60) = 20×0.15
g = 20×0.15/0.20 = 15
The amount of 80% juice needed is 15 gallons, so 5 gallons of 60% juice are needed.
The square root of 36/100 is c. -6/10 and 6/10
You can get this by using a calculator.
