Answer:
x = 12 hours
Step-by-step explanation:
If one pipe fills store pool in 12 hours in 1 hour will fill 1/12 of the pool
If one pipe fills a store pool in 6 hours in 1 hour will fill 1/6 of the pool
Let call " x " number of hours needed by the third pipe to fills the pool
then in 1 hour will fill 1/x
The three pipes working together in 1 hour will fill
1/12 + 1/6 + 1/x
Now we know that the three pipes take 3 hours to fill the pool then in 1 hour three pipes will fill 1/3 of the pool, therefore
1/12 + 1/6 + 1/x = 1/3
( x + 2*x + 12) /12*x = 1/3 ⇒ ( 3*x +12 )/ 12*x = 1/3
9*x + 36 = 12*x
- 3*x = - 36
x = 36/3
x = 12 hours
Not skewed, I can tell dawgggg ooooohhhhh and I’m wasted
Answer:
36 miles per hour if you were trying to multiply it.
Step-by-step explanation:
Answer: It will take 8 years.
Step-by-step explanation:
Equation for interest compounded continuously:
, A = accumulated amount , P=Principal value , r =rate of interest , t= time.
Given: P= $8,310 , r = 2% , A= $9,751.88
Taking natural log on both sides
Hence, it will take 8 years.
