Answer:
Step-by-step explanation:
h(t) = -16t² + 14400
0= -16t² + 14400
(1/-16)×-14400=-16t²(1/-16)
900=t²
30=t
So if 6 out of 40 are incorrect, 40-6= 36 must be correct.
In order to gain percentage you do proportions.
36/40 = x/100.
Multiply 36 times 100 then divide by 40, which is 90.
The answer is 90%.
90% of the questions he got were correct.
