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
The answer you will get is 8 because your going to do 6+10 which equal 16 then divide 16 divide by 2 which gives you 8
I mean it helps so not really but its 5 !! hope this helps
Answer:
1 : 656250
Step-by-step explanation:
It is given that we need to dissolve 8 tablets of active ingredient B, each containing 3 mg, in 15,750 mL.
Tablets = 8
Weight of each tablet = 3 mg
Total wight of tablets = 8 × 3 = 24 mg
Total volume = 15,750 mL.
1 mL = 1000 mg
Total volume = 15,750000 mg
We need to find the ratio strength (w/v).
Therefore, the ratio strength (w/v) is 1 : 656250.
You want to undo the (-9 1/2), so you will add 9 1/2 to each side
