Answer:
First Question: <u>63 coins are not nickels.</u>
Second Question: <u>63+n=91</u>
Step-by-step explanation:
For your first question: 29+21=50 and 50+13=63. 63 coins are not nickels.
For your second question: You can do 29+21+13+n=91, I just simplified and said 63+n=91. You can choose.
Hope that this helps! Good luck with what you're working on!
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.
Given points (0, 1) and (-7, 5):
Let (x1, y1) = (0, 1)
(x2, y2) = (-7, 5)
First, solve for the slope of the line using the formula:
m = (y2 - y1)/(x2 - x1)
m = (5 - 1) / (-7 - 0)
m = 4/-7 = -4/7
Now that we have our slope, m = -4/7, we can plug this in, along with one of the given points, (0, 1), into the point-slope form:
y - y1 = m(x - x1)
y - 1 = -4/7(x - 0) ← This is the point-slope form

Answer:
22 (4th option)
Step-by-step explanation:
The side lengths are useless.
Pay attention to the angles.
<QRP=68 degrees.
Vertical angles make it so <SRT=68
180-90(right angle)-68=22 degrees
