A rectangle swimming pool is 8 feet deep. One side of the pool is 4.5 times longer than the other. The amount of water needed fo
wel

The side lengths of the pool 10 ft and 45 ft.

<u>SOLUTION: </u>

Given, a rectangle swimming pool is 8 feet deep.  

One side of the pool is 4.5 times longer than the other.  

Let the length of pool be n feet, the width will be 4.5n feet

The amount of water needed for the swimming pool is 3600 cubic ft

We have to find the dimensions of the pool. Now, we know that,  

\begin{array}{l}{\text {volume of pool}=\text {depth} \times \text {length } \times \text {width}} \\\\ {\rightarrow 3600 \text { cubic } f t=8 \text { feet } \times \text { n feet } \times(4.5 n) \text { feet }} \\\\ {\rightarrow 8 n \times 4.5 n=3600} \\\\ {\rightarrow 36 n^{2}=3600} \\\\ {\rightarrow n^{2}=100}\end{array}

On taking square root on both sides we get,

\begin{array}{l}{\rightarrow\sqrt{n^{2}}=\sqrt{100}} \\\\ {\rightarrow n=10 \mathrm{ft}}\end{array}

So, the width will be 4.5 n=4.5 \times 10=45 \mathrm{ft}

Sophie [7]

Answer:

Step-by-step explanation:

You need two facts

  • The smallest angle is opposite the smallest side
  • The name is the letter not making up the line.

RP is the smallest side

Q is the smallest angle

PQ is the next smallest side

R is the next smallest angle

QR is the largest side

P is the greatest angle

<Q  <R   <P is the correct order from smallest to largest

That's the second one from the top.

My name is Ann [436]

First find the area of the triangle at the end.

Area of a triangle is 1/2 x base x height.

The triangle is a right triangle with a base of 4 and height of 3


area = 1/2 x 4 x 3 = 6 square cm


Now to find the volume multiply the area of the triangle by the length of the prism.


volume = 6 square cm x 11 cm = 66 cubic cm.


answer: 66 cm^3
