Answer:

About 6 hours.

Step-by-step explanation:

The cylinder has a diameter of 10 meters and a depth of 1.4 meters.

First, we can find the volume of the cylinder, given by the formula:

V=\pi r^2h

Where r is the radius and h is the height (or depth, in this case).

Since our diameter is 10, our radius is 5.

Therefore, the volume of the cylinder will be (using 3.14 as π):

V=(3.14)(5)^2(1.4)=109.9\text{ meters} ^3

Since water is pumped at a rate of 18 cubic meters per hour, it will take then:

109.9/18=6.10\overline{5}\approx 6\text{ hours}

So, it will take about 6 hours for the water to completely fill the pool.

What is equivalent to 7^13/7^7
Deffense [45]

The equivalent expression to 7^13/7^7 would be 7^6.

<h3>What are equivalent expressions?</h3>

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.

To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.

We have given an expression as  7^13/7^7

The equivalent expression;

\dfrac{7^{13}}{7^7} \\\\7^{13-7}\\\\7^6

Hence, The equivalent expression to 7^13/7^7 would be 7^6.

Which expreion are equivalent to
Makovka662 [10]

The expression equivalent to the expression -90 - 60w is -30(3 + 2w),  (-9 - 6w)10 and  -20(4.5 + 3w)

We need to find the expressions that are equivalent to given expression

We solve the expression and check,

A) -30(3 + 2w)

-90 - 60w

Yes it is equivalent.

B) (-9 - 6w)10

-90 - 60w

Yes it is equivalent.

C) -3(30 - 20w)

-90 + 60w

No it is not equivalent.

D)(6 + 4w)15

90 + 60w

No it is not equivalent.

E) -20(4.5 + 3w)

-90 - 60w

Yes it is equivalent.

Therefore, The expression equivalent to the expression -90 - 60w is -30(3 + 2w),  (-9 - 6w)10 and  -20(4.5 + 3w)
