(Lots of points)PLEASE HELP ME Due today at 8:59 in Texas
IceJOKER [234]

Answer:

6.) So 8 of 24 hours is 1/3. So the percent of his time used was <u><em>33.33333 . . %</em></u> (etc)

7.) The easiest way to figure out a percentage is dividing it. So if it was 30 hit out of 75 people, then divide 30 by 75. So <u><em>40%</em></u> of them got hit.

Hope that helps

Write the equation of the line with an x-intercept at (0,2) and perpendicular to 3x+4y=12.
juin [17]

First you normalize 3x+4y=12 into y = -3/4 x + 3 (dividing by 4).

Then you observe that the slope of the line is -3/4 (it's always the factor with the x). A perpendicular line has the reciprocal slope. Reciprocal means inverted and negated. So -3/4 becomes +4/3.

The equation will thus look like y = 4/3 x + b. To find b, we fill in the given x intercept (0,2), (we get 2 = 4/3 * 0 + b). With x=0, b must be 2.

So the equation is: y = 4/3 x + 2

Greeley [361]

Answer:

12\dfrac{1}{8}\ feet

Step-by-step explanation:

Sonya drops a marble while standing on a deck 7 \dfrac{7}{8} feet above the ground.

The marble falls 4 \dfrac{1}{4} feet from Sonya's hand to the deck, and then rolls and falls to the ground.

So, the ball falls 4 \dfrac{1}{4} feet from Sonya's hand to the deck  and 7 \dfrac{7}{8} from the deck to the ground, in total

4\dfrac{1}{4}+7\dfrac{7}{8}=4\dfrac{2}{8}+7\dfrac{7}{8}=(4+7)+\dfrac{2+7}{8}=11+\dfrac{9}{8}=11+1\dfrac{1}{8}=12\dfrac{1}{8}\ feet
