Answer:
11.7 days
Step-by-step explanation:
Given that:
Filling rate = 8 quarts per hour
150 barrels picked up per trip
One barrel = 15 quarts of waste water
Barrel picked up per trip = 150 barrels
Number of quarts per barrel = 15 quarts
Total quantity of waste water = (150 * 15) = 2250 quarts
Filling rate = 8 quarts per hour
Time taken = quantity / rate
Time taken in days = 2250 quarts /(8*24) = 11.72
11.7 days
Answer:
The percentage when both quantities gets mix = 65 %
Step-by-step explanation:
Given as :
The quantity of base = 50 gallons
Now 20% of 50 gallons =
× 50
I.e 20% of 50 gallons = 10 gallons
Again
The quantity of heavy batch = 150 gallons
Now 80% of 150 gallons =
× 150
I.e 80% of 150 gallons = 120 gallons
Now, Total new quantity = 10 gallons + 120 gallons = 130 gallons
And initial total quantity was = 50 gallons + 150 gallons = 200 gallons
∴ percentage when mix both of them =
× 100
I.e percentage when mix both of them = 65 %
Hence The percentage when both quantities gets mix = 65 % answer
