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

Explanation:
We view the ramp as a right triangle. The hypotenuse is 4.2 and the vertical side .7, which is opposite the angle
θ
we seek.

I'm going to finish the problem but I'll note if we were actually building the ramp we don't need to know the angle; this sine is sufficient.

which I think is a pretty steep ramp for a wheelchair.
There will be another inverse sine that is the supplementary angle, around

, but we can rule that out as a value for a ramp wedge angle.

Like wat is it like i need was you need to show me your Question so i know what you talking about
Answer:
- 4 1/6 min or 4 min 10 sec
Step-by-step explanation:
<u>Filling rate is:</u>
- 15 ÷ 1 1/4 = 15 ÷ 5/4 = 15 × 4/5 = 12 l/min
<u>Total volume is 50 l, time required to fill is:</u>
- 50/12 = 4 2/12 = 4 1/6 min or 4 min 10 sec
