Answer:
8.94
Step-by-step explanation:
5 - (-3) = 8
3 - (-1) = 4
a²+b² =c²
4² + 8² = c²
c = 8.94
134,000x 0.08= 10,720= the money you get every year from interest
1,000,000/10,720= 93.28... or 93 years
<span>12/25=x/88
12(88)=25(x)
1056=25x divide both sides by 25
x=42.24</span>
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
