0% of 36: 0

100% of 36: 36

25% of 36: 9

75% of 36: 27

Step-by-step explanation:

0% of any number is 0.

100% is the same number.

To find 25% you can divide by 4.

To find 75% you can divide by 4 and multiple by 3.

25% = 1/4

75% = 3/4

I hope this is helpful :)

Okay so i’m thing that the number that is gray means that, that is the measure of the whole angle. If I am correct then that means all you have to do is subtract the angle given from the whole angle to get x. Here is what I mean.

1. (117° - 94° = 23°) so x = 23°

2. These are vertical angles, which means that they will equal each other. So x = 148°.

3. (174° - 68° = 106°) so, x = 106°

4. (50° - 32° = 18°) so, x = 18°

5. Okay so since this is a straight line, it the bottom half does not matter. The straight line equals 180°. So here is you equation.
(125° + x° + 30° = 180°. So let us add 125 & 30, which would get us 155°. Now let us subtract 155° from 180°, and that would get us, 25°. So x = 25°.

6. Once again these are vertical angles, meaning the will equal each other. So x = 113°.

7. So since x and 30° are on a straight line, x, 30° and the middle angle should equal 180°: Since the middle angle is vertical to 105°, the middle angle equals 105°. So now your equation is. 30° + 105° + x° = 180°. Now let us add 30° and 105° which would give us 135°. Now let us subtract 135° from 180° and that would give us, 45°, so therefore, x = 45°.

8. All you have to do is add all three angles. So your equation is:
(30° + 15° + 89°)
This will give you 134°. Therefore, x = 134°.

9. Once again these are vertical angles so x = 162°.

10. Okay so here your equation will be x = 90° + 29°. Imma tell you why.

Now the angle with the box in it, is obviously 90°. x is vertical from the whole angle on 90° and 29°, which means what? THEY SHOULD EQUAL EACH OTHER. So 90° + 29° = 119°. So
x = 119°.

Answer:

y = 0,4x -1 or y = 2/5 x -1

Step-by-step explanation:

you can use the slope formula

m = y2-y1 / x2-x1

m = -1 - (-3) / 0 - (-5) = 2/5

Answer:

y = 2/5x - 1

Step-by-step explanation:

Points on the graph: ( -5, -3) and (0, -1)

Slope:

m=(y2-y1)/(x2-x1)

m=(-1+3)/(0+5)

m = 2/5

Slope-intercept:

y - y1 = m(x - x1)

y + 3 = 2/5(x + 5)

y + 3 = 2/5x + 2

y = 2/5x - 1

Martin Luther King dreams that the people of this world will not judge others by the color of their skin, but by the content of their character. He claims that the world will not be able to shatter the Shackles of prejudice, half-truths, and downright ignorance while judging others by their skin color or culture, therefore we should let go of this rotten habit and view others through a clean sheet. The best way to assure we don't fall into this habit is by believing that Culture does not make people, people make culture, Chimamanda Adichie explains during her TED talk. She claims that this is also how a single story gets created. Show people as one thing, as only one thing, over and over again, and that is what they become. In Adichies TED talk, she explains how the news and storys force a single story. The story of Adichie and her roommate proves this claim. Adichie described how her roommate had felt sorry for her even before she met her. Her roommate has been shown the single story of catastrophe and pity and not the happy sides of Africa. She had seen the news and war photos of Africa, thinking that that's all that ever took place in Africa. Adichie explains how you can prevent this by simply asking questions. If you don't understand, ask questions. If you're uncomfortable about asking questions, say you are uncomfortable about asking questions and then ask anyway., Adichie says. By asking questions you can get around both prejudice and single stories, so ask away! There are 15 boys and 18 girls in seventh grade. Find the ratio of boys to girls in seventh grade.
