Answer:
a) To earn C he needs at least 68 and less than 98
b) No, he couldn't make it.
Step-by-step explanation:
I. His avg value is (382 + x)/6
I pick a random number and that gave
(68 => to reach 75) and (98 => to reach 80)
So that makes he needs at least 68 and less than 98
II. The reason why he cannot make it is
if 100 is 100%
= (100 + 382)/6
= 80.33 That's impossible to reach 90
Hope that help :)

Answer:
5 seconds
Step-by-step explanation:
H= -16t2 + 400
Hit ground
H=0
0 = -16t2 + 400
0 = -16 ( t2 - 25)
-16
t2 -25 = 0
(t + 5)(t - 5) = 0
t + 5 = 0
- 5 -5
t = -5
t - 5 = 0
+ 5 +5
t = -5
t = 5
5 seconds to hit the ground
