Answer:

It will take 4.4 hours to fill the swimming pool when two pumps are opened.

Step-by-step explanation:

Given:

One pump can fill a swimming pool in 8 hours and another pump can fill it in 10 hours.

First we need to calculate, in 1 hour how much water a pump pour into the swimming pool.

In 1 hour, the first pump can pour water into the swimming pool = \frac{1}{8}

In 1 hour, the second pump can pour water into the swimming pool = \frac{1}{10}

Let "t" be the time taken to fill the pool when two both the pups are opened.

\frac{1}{8} + \frac{1}{10} = \frac{1}{t}

Now we have to solve for t. We have to take LCD of 8 and 10.

The Least common denominator (LCD) of 8 and 10 is 40.

\frac{5}{40} + \frac{4}{40} = \frac{1}{t}

\frac{5 + 4}{40} = \frac{1}{t}

\frac{9}{40} = \frac{1}{t}

Now we have to cross multiply and solve for t

9t = 40

Dividing both sides by 9, we get

t = 4.444

Which is approximately, t = 4.4 hours.

Therefore, it will take 4.4 hours to fill the swimming pool when two pumps are opened.

larisa86 [58]

the parallel line is 2x+5y+15=0.

Step-by-step explanation:

ok I hope it will work

soo,

Solution

given,

given parallel line 2x+5y=15

which goes through the point (-10,1)

now,

let 2x+5y=15 be equation no.1

then the line which is parallel to the equation 1st

2 x+5y+k = 0 let it be equation no.2

now the equation no.2 passes through the point (-10,1)

or, 2x+5y+k =0

or, 2*-10+5*1+k= 0

or, -20+5+k= 0

or, -15+k= 0

or, k= 15

putting the value of k in equation no.2 we get,

or, 2x+5y+k=0

or, 2x+5y+15=0

which is a required line.
