1 gal    3 qts    7 pts
1 gal    3 qts    3 pts

3 gal    8 qts    13 pts

1 pt = 0.5 qts...so 12 pts = 12* 0.5 = 6...so now we have :
3 gal   14 qts   1 pt

1 qt = 0.25 gal..so 12 qts = 12 * 0.25 = 3 gallons...so now we have :
6 gal   2 qts   1 pt <===

PLEASE HELP!!! I am struggling

The ball will be at height 19 feet first at 0.7 sec and then at 1.42 sec.

<u>Explanation:</u>

We need to find the time at which the ball will be at height 19 feet.

Equation:

h = 3 + 34t - 16t²

19 = 3 + 34t - 16t²

16 = -16t² + 34t

-16t² + 34t - 16 = 0

On solving the equation, we get

t1 = 0.7 s and t2 = 1.42s

Therefore, the ball will be at height 19 feet first at 0.7 sec and then at 1.42 sec.
