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.
To solve this problem, draw the situation for a better comprehension:
As we can see, the situation describes a right triangle and we can use pythagorean theorem to solve it.
To do this, use the corresponding units.
For inches:
![\begin{gathered} h=\sqrt[]{84^2-48^2} \\ h=\sqrt[]{7056-2304} \\ h=\sqrt[]{4752} \\ h=68.9 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20h%3D%5Csqrt%5B%5D%7B84%5E2-48%5E2%7D%20%5C%5C%20h%3D%5Csqrt%5B%5D%7B7056-2304%7D%20%5C%5C%20h%3D%5Csqrt%5B%5D%7B4752%7D%20%5C%5C%20h%3D68.9%20%5Cend%7Bgathered%7D)
The suspect is 68.9 inches high.
Convert this height to feet:

The suspect is 5.74 feet high.
Answer:
Elimination
x = 2
y = -2
Step-by-step explanation:
Elimination
2x + 4y = -4
2x - y = 6
Subtract the second equation from the first
5y = -10
Divide both sides by 5
y = -2
---------------------
Substitute for y = -2 in the second equation
2x - -2 = 6
2x + 2 = 6
subtract 2 from both sides
2x = 4
Divide both sides by 2
x = 2

Answer:
MKL = 36°
Step-by-step explanation:
(3x + 6) + (6x + 12) = 54°
3x + 6x + 6 + 12 = 54
9x + 18 = 54
9x = 54 - 18
9x = 36
x = 36/9
x = 4
MKL = 6x + 12
MKL = 6(4) + 12
MKL = 24 + 12
MKL = 36°
