Answer:
The average velocity is 19.44 m/s.
Step-by-step explanation:
The average velocity between two points can be calculated with the following formula:

The procedure is to calculate the difference for both distance and time, and dividing the two differences, we get the average velocity.
Answer:
k=1
Step-by-step explanation:
-2k+10=64k-56
66=66k
k=1
Answer:
4 seconds
Step-by-step explanation:
We can get the answer to this equation by solving for the variable (r).
7.4 - 9 - 2r = 18
We want to get r on one side, so we want to push everything else to the other side.
-2r = 18 - 7.4 + 9
-2r = 19.6
2r = -19.6
r = -9.8
Answer:
20 inches
Step-by-step explanation:
Since the cape is trapezoid shaped and has an area of 600 in², the area of a trapezoid is given by
A =1/2(a + b)h where a = length along the top of the cape = 24 in, b = length along the bottom of the cape = 36 in and h = height of the cape
So, h = 2A/(a + b)
= 2 × 600 in²/(24 in + 36 in)
= 1200 in²/60 in
= 20 in
So, the height of the cape is 20 inches
