Alright so the sin of anything is <em>opposite/hypotenuse.

</em>we can keep this in mind and use the information we have...
<em>
</em>Opposite of <NOM = 3
<em>
</em>To find the hypotenuse we will use the pythagorean theorem...
<em>
</em><em>a</em>²+<em>b</em>²=<em>c</em>²
3²+<em>4</em>²=<em /><em>c</em>²
<em>9+16=c</em>²
<em>25=c</em>²
√<em>25=</em>√<em>c</em>²
<em>c=5
</em>
Knowing that the hypotenuse is 5, we can use the sin formula and find that...

sin(<NOM)= 3/5
I hope this helps!

The number of men and women participating in the Winter Olympic Games has been steadily increasing in recent years. In the 19th
Montano1993 [528]

Using a system of equations, it is found that the correct option is:

A) 1389x+1660y=787x+1121y.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, considering the amounts in each olympics(1389 men and 787 women participated on the 19th, 1660 men and 1121 women in the 22th), the system is:

A) 1389x+1660y=787x+1121y.

calculate how much 1% salt solution must be mixed with how much 5% salt solution to make 100 milliliters of 2% salt solution. yo
Setler79 [48]
Let x be the amount (the volume in milliliters) of the 5% solution to be mixed.

Then the volume of the 1% solution is 100-x milliliters.


Then your "concentration" equation is

%280.01%2A%28100-x%29+%2B+0.05%2Ax%29%2F100 = 0.02,


or, equivalently,

100-x + 5*x = 200,

which implies

4x = 100 ----> x = 100%2Fx = 25.


Answer: 25 milliliters of the 5% solution must be mised with 100-25 = 75 milliliters of the 1% solution.

HELP PLEASE. 3(2x+3)=15​
pantera1 [17]

If you are  solving for X then we have to do a few process

What you would want most is to remove the parentheses, so to do that i would use distributive property

3*2x is 6x and 3*3 is 9  so our new equation will look like

6x+9=15 if you don't understand please tell me

now we must bring the 9 over

If you bring the 9 over than it would become negative

6x=15-9

so 6x=6

and now you can solve the answer is x=1
