Answer:
90° CCW
Step-by-step explanation:
The slope of BA is -1/3. The slope of BA' is 3, so the slopes are opposite reciprocals of one another. These segments are perpendicular, meaning the angle between them is 90°.
Point A' has been rotated 90° CCW about point B.
We first find the lines of the motion of each truck, then calculate its intercept.
Garbage truck:
m = (12 - 4) / (5 - 3)
m = 4
4 - y = 4(3 - x)
4x - y = 8
Dump truck:
m = (33 + 3) / (-4 - 5)
m = -4
33 - y = -4(-4 - x)
4x + y = 17
Adding the two equations to solve them, we get:
8x = 25
x = 25 / 8
y = 17 - 4(25/8)
y = 17 - 25/2
y = 9/2
The trucks' point of intersection is (25/8,9/2)
10. If it rained 7/10 of the days, 3/10 days did not receive rain.
90 days multiplied by 3/10 is 27.
It would not rain about 27 days in the 90 days.
11. x multiplied by 8 and a half equals 5.
(8 and 1/2)x = 5
x = .588235 which is about 6/10
12. C = 6/10 and D = 8/10 so the product would be 48/100 which is close to 5/10. This point is N.
