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.

HELP When 2((Three-fifths x + 2 and three-fourths y minus one-fourth x minus 1 and one-half y + 3)) is simplified, what is the r
lesya692 [45]

Answer:

<h2> StartFraction 7 over 10 EndFraction x + 2 and one-half y + 6</h2>

Step-by-step explanation:

Given the expression 2(\frac{3x}{5}+2\frac{3y}{4}-\frac{x}{4}-1 \frac{1}{2}y+3)

To simplify the expression, we need to first collect the like terms of the functions in parentheses as shown;

= 2(\frac{3x}{5}-\frac{x}{4}-1 \frac{1}{2}y+2\frac{3}{4}y+3)\\= 2(\frac{3x}{5}-\frac{x}{4}- \frac{3}{2}y+\frac{11}{4}y+3)\\

Then we find the LCM of the resulting function

= 2(\frac{3x}{5}-\frac{x}{4}- \frac{3}{2}y+\frac{11}{4}y+3)\\= 2(\frac{12x-5x}{20} - (\frac{6y-11y}{4})+3)\\= 2(\frac{7x}{20}- (\frac{-5y}{4})+3 )\\= 2(\frac{7x}{20}+ \frac{5y}{4}+3 )\\= \frac{7x}{10} + \frac{5y}{2} +6\\=  \frac{7x}{10} + 2\frac{1}{2}y+6\\

The final expression gives the required answer
