A.) if 4oz is drank every 4 hours, and there are 24 hours in a day, then there are 6 times during each day that the baby drinks formula. Knowing this, multiply 6 and 4 to get 24oz of formula each day
b.) if 1 can = 91fl oz, and, let's say 30 days in a month, then 24 multiplied by 30 will gives us how much is drank each month which is equal to 720fl oz. Divide 720 by 91 to get approximately 8 cans for one month.
c.) Go back to sub-problem a to find that the new amount per day is now equal to 16oz (6oz/4hrs ... 24/6 = 4 ... 4*4 = 16). Now take 30 and multiply it by 16 to get 480fl oz. Divide 480 by 91 to get approximately 5 cans for one month.
<span>Let x=amount of time it takes both pipes draining together to empty the pool
First pipe empties at the rate of 540,000/150=3600 liters/min
Second pipe empties at the rate of 540,000/225=2400 liters/min
Together, both pipes empties at the rate of 3600+2400=6000 liters/min, so our equation to solve is:
6000*x=540000 </span>
Answer:
Step-by-step explanation:
The answer is c the third one
This is the commutative property
Answer:
It will take 18 minutes to fill the trough using both pumps.
Step-by-step explanation:
Given that:
Time taken by pump A = half hour = 30 minutes
Time taken by pump B = three quarters of an hour
One quarter = 
One hour = 60 minutes
Three quarters of an hour = 
= 45 minutes
Let,
x be the time taken by both pumps to fill the trough.
Hence,
It will take 18 minutes to fill the trough using both pumps.
