Each person will get 6/8. Hope this helped.
Answer:
B) 43.82 feet/sec
Step-by-step explanation:
Fill in the number and evaluate:
v = √(64×30) = √1920 ≈ 43.82 . . . . ft/s
_____
Of course, √(64h) can be simplified to 8√h. You know that √30 lies between 5 and 6, so the velocity lies between 8·5 = 40 and 8·6 = 48. There is only one answer choice in that range.

I'm answering in this format because the questions aren't numbered, so its hard to reference them consistently (so we're both on the same page).
All decimal values are approximate. I decided to round to 4 decimal places, but feel free to use another level of precision.
Negative 9 because 51 - 60 = 9
I believe the answer would be 10.39, since the square root of 75 is 8.66 and the square root of 3 is 1.73. Adding them both would give you 10.39. Hope this helped!
