Answer:

t = 1 second

Step-by-step explanation:

Given:   h = 16 ft

This movement is vertical free fall without initial velocity V₀ = 0

We will accept value of g= 10 m/s², but we must convert meters in the ft.

We know that 1 meter = 3.28 ft =>  10 meters = 32.8 ft

According to this g= 32.8 ft/s²

The formula for calculating height is:

h = g · t²/ 2  => t² = 2 h/ g  =>  t = √2 h / g

t = √ 2 · 16 / 32.8 = √ 32/32.8 = √ 0.98 = 0.99 ≈ 1 second

t = 1 second

God with you!!!

Tom [10]

Answer:

5n

Step-by-step explanation:

Think about it:

If Tommy has 4 friends (n = 4), then he will have to give 5 pencils to each person. The total number of pencils is 5 * n or 5 * 4 = 20.

Similarly, if Tommy has 0 friends (I can relate), then he will have to give 5 pencils to each of his imaginary friends. The total number of pencils he has to give out to his real friends is 5 * n or 5 * 0 = 0.

If a bag contains 4 red marbles, 7 green marbles, 9 yellow marbles, and 2 black marbles. If you randomly draw a marble from the
Soloha48 [4]

I think that it would be B). 1/2

The reason I think that is because if you add all the marbles up you get 22. Then if you add the red and the green marbles you get 11. 11 is half of 22 making it a 50% chance. 1/2 is the same as 50% or a half.
