Answer:
12√2 cm
Step-by-step explanation:
We know that a 45-45-90 triangle has legs of <em>x</em> and a hypotenuse of x√2. Since we are given <em>x</em> as 12, we have:
x = 12
x√12 = 12√2

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.
