The amount of water needed to fill the swimming pool completely is 864 cubic meters.

Given that each of the four sides of a swimming pool measures 12 m the pool is 6 m deep.

"Volume" is a mathematical quantity that indicates the amount of three-dimensional space occupied by an object or surrounding surface. Volume units are cubic units like m³, cm³, in³, etc.

As we know, the swimming pool is in cubic shape.

So, we will find the volume of cube using the formula V=l×b×h.

Here, l=12m, b=12m and h=m.

Now, we want to substitute the values in the formula, we get

V=12m×12m×6m

V=864m³

Hence, the amount of water needed to fill completely the swimming pool whose each of the four sides of a swimming pool measures 12 m the pool is 6 m deep is 864 cubic meters.

If the student has already read 2525 of the pages, how long will it take them to read the rest of the book? _____ minutes Your a
Alja [10]

The number of pages the student can read in a minute is an illustration of rates.

The time left to complete the whole book is 90 minutes

From the complete question, the student's rate is:

\mathbf{Rate = 50\ pages/hr}

The number of pages is:

\mathbf{Total = 100\ pages}

First, we calculate the time to read the whole book

\mathbf{Total\ Time = \frac{Total\ pages}{Rate}}

\mathbf{Total\ Time = \frac{100\ pages}{50\ pages/ hr}}

\mathbf{Total\ Time = 2\ hours}

The number of the student has read is:

\mathbf{Pages = 25}

Next, we calculate the time spent on the 25 pages

\mathbf{Time\ Spent = \frac{Pages}{Rate}}

\mathbf{Time\ Spent = \frac{25\ pages}{50\ pages/hr}}

\mathbf{Time\ Spent = 0.5\ hr}

Convert to minutes

\mathbf{Time\ Spent = 30\ minutes}

So, the time left is:

\mathbf{Time\ Left = Total\ Time - Time\ Spent}

This gives

\mathbf{Time\ Left = 2\ hours- 30\ minutes}

\mathbf{Time\ Left = 1\ hour, 30\ minutes}

Convert to minutes

\mathbf{Time\ Left = 90\ minutes}

Hence, the time left is 90 minutes

Given the function h(x), determine the functions which correctly decompose h(x) into component functions f(x) and g(x) so that h

\text{Hi there! :)}

\large\boxed{g(x) = 7x + 2\text{ , } f(x) = \sqrt{x}  - 10}

\text{h(x) = f(g(x)), so determine what g(x) was substituted into f(x):}\\\\\text{Given the equation } h(x) = \sqrt{7x +2}- 10:\\\\\text{In the part of the equation with a variable, we see that "7x + 2" is in a square root:}

\text{Therefore, we can say that g(x) = 7x + 2:}\\\\\text{If h(x) = f(7x + 2), then f(x) must be:}\\\\f(x) = \sqrt{x} - 10

\text{The respective functions would be:}\\\\g(x) = 7x + 2\\\\f(x) = \sqrt{x}  - 10

the surface area of a sphere is 1,017.36 square inches.what is the volume of the sphere? use 3.14 for pi
emmasim [6.3K]

Answer:

<em>Area = 254.34 inches ³</em>

Step-by-step explanation:

The formula to find the surface area of a sphere is:

SA = 4\pi r^{2}

To find the volume of the sphere, we first need to figure out the radius (r) of the sphere. We can accomplish this by reversing the formula that was used to find the surface area. (1017.36 in^{2})

SA = 4\pi r^{2}

1017.36 = 4\pi r^{2}

Divide both sides by pi (3.14).

1017.36 = 4\pi r^{2}

324 = 4 r^{2}

Divide both sides by 4.

324 = 4 r^{2}

81 = r^{2}\\

Find the square root of both sides.

81 = r^{2}\\

\sqrt{81} = r

<em>radius = 9</em>

<em />

Insert the value of the radius into the formula for finding the volume of a sphere. (A=\pi r^{2})

(A=\pi r^{2})

A=\pi (9)^{2}

A=\pi (81)

A = 254.34

<em>Area = 254.34 inches ³</em>

<em />

~Hope this helps!~
