20 POINTS!!!! FULL ANSWERS PLEASE Shannon is making a circle graph to show the type of weather for the past month. There are 12
sunny days, 8 cloudy days without rain, and 10 rainy days. When drawing the sector to show the number of cloudy days without rain, what angle measure should Shannon use? Justify your answer
1 answer:
Just to make it clear here is the graph. I was gone so long, it destroyed my answer.
Very briefly
8/30 * 360 = 96 which is the angle for the cloudy days.
12/30 * 360 = 144 which is the angle for the sunny days
10/30 * 360 = 120 which is the angle for the rainy days.
The graph shows how this would be plotted. It's not really well done, but it is there.

Answer:
- 0.25|h -1600| -400
- 1000
- 2200
Step-by-step explanation:
Once again, you can choose the correct equation by finding the one that gives d=0 for h=0. (Note that the problem statement requires the independent variable to be h, not x.)
Then you can use that equation to find h for d=-250:
-250 = 0.25|h -1600| -400
150 = 0.25|h -1600|
600 = |h -1600|
This resolves to two equations:
- -600 = h -1600 . . . ⇒ . . . h = 1000
- 600 = h -1600 . . . ⇒ . . . h = 2200

Or, you can realize the distance from the west end is 4 times the depth. At a depth of 250 ft, that distance is h=1000 ft. That is 600 ft from the center, so 1200 ft from the same depth on the other side of the crater, which is at h=2200 ft.
