Answer:
350 mL
Step-by-step explanation:
Let q represent the quantity (in mL) needed of the 70% solution. Then the total amount of mixture will be q+50 milliliters. The total amount of alcohol in the mixture will be ...
0.70q +0.30(50) = 0.65(50 +q)
.05q = 17.5 . . . . . . subtract (0.65q +1.50)
q = 350 . . . . . . . . . divide by 0.05
You will need 350 mL of the 70% solution.
Base b = 4.4 m
Height h = 250cm = 2.5 m
So area A = 1/2 * b * h = 1/2 * 4.4 * 2.5
= 5.5 m^2
Pretty sure your answer would be 50,000.
If 20 min = 1 day
1 week = + 10 mins
= 30 mins
6 weeks = 60 mins
1 hour 30 mins = 7 weeks
