First, let x be the amount of 20% acid solution in liters. With this, 60 - x is the amount of 50% solution. The acid balance before and after mixing becomes,
(0.2)(x) + (0.5)(60 - x) = (0.40)(60)
The value of x is 20. Therefore, Gabe needs 20 liters of 20% acid solution and 40 liters of 50% acid solution.
It's 50 because 3 is half of 6
Answer:
120 ft
Step-by-step explanation:
A slope of 12/100 means for every 12 units of distance you move horizontally you descend by 100 of the same units vertically. Assuming now that the slope does not change, i.e it remains constant throughout your trip; descending by 1000 ft should mean you have moved horizontally by 120 ft so that the slope is maintained.
x/1000 = 12/100
x = 120 ft
