Let the time taken for the first pipe to fill the pool be x hours
time taken for second pipe to fill the pool is (x+7) hours
time taken for both pipes to fill the pull =(x-9) hours
thus fraction of time taken for both will be written as:
1/(x-9)
thus total fraction for pipe 1 and 2 will be
1/x+1/(x+7)=1/(x-9)
solving for x we get:
x=-3 or x=21
but time is positive, then time taken by first pipe is 21 hours
time taken by both pipes will be 21-9=12 hours
Answer: 14 miles
Step-by-step explanation:
In the attached figure we can see the two segments the man drove, where the 
is the distance of a road that goes from the man's home directly to his work.
It should be noted that is also the hypotenuse of the righ triangle formed. Hence, we can use the Pithagorean theorem to find this distance:
Then:
To solve this problem you must apply the proccedure shown below:
1. You have that the forest fire covers 1600 acres at time t=0. the fire is growing at a rate of 9√t<span> acres per hour. Therefore, you have:
</span>
1600+∫(9√t)dt (from 0 to 16)
2. Then, when you solve it, you obtain:
1600+6t^3/2=1984
3. Therefore, as you can see, the answer is: 1984 acres.
First let's find the number of ham slices.
90-63 = 27
Then divide it by the total amount to get your percent.
27/90 = 3/10 = 30%
It is 30% ham. Hope this helps!
Answer:
m = 17h
Step-by-step explanation:
85/5 = 17 (she makes $17 per hour)
Therefore:
m = 17h
