Answer:
180 cm
Step-by-step explanation:
Number of trials per team = 3
Distance per trial for team D's car is the same for each trial, let distance = x
Distance per trial for team C's car is 1cm farther than team D's distance and the same for each trial, hence, distance = x + 1 per trial
Total distance traveled by C = 543 cm
This means :
(x + 1) + (x + 1) + (x + 1) = 543
3x + 3 = 543
3x = 543 - 3
3x = 540
x = 540 / 3
x = 180
Hence, distance traveled per trial for team D's car = x = 180 cm
It's B
Slope is negative, the other must be positive due to m1 x m2 = - 1
m1 = -2/5
The diagram shows a gradient of -2/5. So, the
reciprocal of this valve to make - 1 is 5/2 (which is the - 2/5 flipped upside down, but positive)
-2/5 x 5/2 = - 10/10 (or - 1)
Thus, the perpendicular line to this has a gradient of 5/2.
Hope this helps!
