Use the trigonometric function.

\sin30^o=\dfrac{x}{20}\\\\\sin30^o=\dfrac{1}{2}\\\\\dfrac{x}{20}=\dfrac{1}{2}\ \ \ |\cdot20\\\\x=10

\sin60^o=\dfrac{y}{20}\\\\\sin60^o=\dfrac{\sqrt3}{2}\\\\\dfrac{y}{20}=\dfrac{\sqrt3}{2}\ \ \ \ |\cdot20\\\\y=10\sqrt3

I really don’t understand what the questions asking? How do I solve this
Eddi Din [679]

Answer:

$17.85

Step-by-step explanation:

Let the dollar amount per shirt be represented by s.

Let the dollar amount per pants be represented by p.

You have the following system:

3s+2p=104.81

2s+1p=61.33

If I multiply the bottom equation by -2, I can set the system up for elimination since the equations are already and the same form and I will have 2p and -2p in the same column there.  2p+(-2p)=0

Multiplying equation 2 by -2:

3s+2p=104.81

-4s-2p=-122.66

-----------------------Add the equations:

-1s      =-17.85

Multiply both sides by -1:

s=17.85

So one shirt cost $17.85

A movie theater uses a cone-shaped container to serve popcorn. The cone has a height of 12 inches and a volume of 16 π in2. What
zimovet [89]

Volume can be defined as the <u><em>capacity of a given container or a certain object.</em></u>

The radius of the cone is 2 inches.

From the question, we are given the following parameters:

<em>The height of the cone = 12 inches</em>

<em>The volume of the cone =  16 π in³</em>

The formula to find the<u> radius of the cone </u>is given as:

√3V/πh

= √ 3 x 16π / π x 12

= 2 inches

Therefore, the radius of the cone is 2 inches.

<h3><u>Question:</u></h3>

Jody is buying a scrap book and designed paper she has 40 dollars and needs at least 18.25 to buy a scrap book each seet of paper cost 0.34 how may sheets of paper can she buy

<h3><u>Answer:</u></h3>

Jody can buy 63 sheets of paper

<h3><u>Solution:</u></h3>

Jody has 40 dollars

Thus, she can spend less than or equal to 40 dollars

She needs at least 18.25 to buy a scrap book

Each seet of paper cost 0.34

Let "s" be the number of sheets of paper

Then,

18.25+0.34s\leq 40\\\\Subtract\ 18.25\ from\ both\ sides\\\\0.34s \leq 40-18.25\\\\0.34s\leq 21.75\\\\Divide\ both\ sides\ by\ 0.34\\\\s\leq 63.9

Thus Jody can buy 63 sheets of paper
