<span>So we want to know how many students out of 144 practice martial arts every day if we know that 7/12 practice every day. So lets multiply the numerator and the denumerator with 12. We will get (12*7)/(12*12)=84/144. And we got our answer: 84 out of 144 students practice every day.</span>

Answer:

84 students out of 144 students practice everyday.

Step-by-step explanation:

Marissa is researching information martial art students, she found that 7 out of 12 martial artist practice everyday.

First we will find the percentage of the sample research.

\frac{7}{12} × 100

= 58.33%

There are 144 martial arts students, so we calculate 58.33% of total students.

\frac{58.33}{100} × 144

= 0.5833 × 144 = 83.995 ≈ 84 students.

84 students out of 144 students practice everyday.

Answer:

Each interior angle of a pentagon equals 108 degrees.

Therefore Angle U = 108 degrees.

The angle of the square is 90 degrees.

Therefore, Angle x = 360 - 108 -90 degrees = 162 degrees!

I beg of you to please some-one help..I can't figure this out and it's driving me nuts- I will give Brainlist!

Answer:

<em>A = 70</em>

Step-by-step explanation:

<em>CB </em>is equal to <em>EZ </em>and <em>E </em>equals 35, and <em>E </em>and <em>C </em>are the same, therefore, both <em>E </em>equals 35. Since there's 180 degrees in a triangle, and <em>ABY </em>equals 105, you have to subtract 180 - 105 to get the other angle. When you do that, you get that <em>B </em>equals 75. You have to add <em>E </em>and <em>B</em> (35 + 75), since that's in the same triangle as <em>A. </em>When you do that, you get 110. Subtract 180 - 110 to get <em>A, </em>which is 70.
