Answer:
x = 12 hrs to fill the pool
Step-by-step explanation: INCOMPLETE QUESTION
Missed information:
Time for two different sizes hoses to fill a small simming pool (let say that is 3 hours)
Time for one of the two hoses to fill a small simming pool ( lt say that is 4 hours)
With that information we can answer the question
If one of the hoses fill the pool in 4 hours, it will fill 1/4 of the pool in 1 hour
We dont know the other hose how long it take to fill the pool so let call that time x hours then in 1 hour it will fill 1/x of the pool
In 1 Hour the two hoses will fill 1/3 of the pool then
In one hour
1/4 + 1/x = 1/3 Solving for x
( x + 4 )/ 4x = 1/3
3x + 12 = 4x
- x = -12 x = 12 hours

Answer:
Step-by-step explanation:
The amount of water in the mix is 2/(5+2) = 2/7 of the volume of the mix. That amount is ...
(2/7)(21 liters) = 6 liters
Then the other 21-6 = 15 liters are antifreeze.
A) To make the mix 1 : 1, 15-6 = 9 liters of water need to be added.
__
B) To make the mix 1 : 2, The total amount of water needs to be brought to 30 liters. 15 more liters need to be added for a total of 24 added liters of water.
Answer:
the answer might be -23 I think but I would I advise to wait until another person answer this question
To get her output per hour, you will have to divide her output by the time she took to produce it (in hour)
So per hour she would produce:
9/2 ÷ 1/6 = 9/2 x 6 = 27
The answer is 27 widgets per hour
