Answer:
t + 3:45 = 11:20 am
Step-by-step explanation:
A rocket is scheduled to launch from a command center in 3.75 hours.
The launch time is 11:20 am.
We need to know the time before 3.75 hours of 11:20 am.
3.75 hours = 3 hours (0.75 × 60) = 45 minutes
Let the current time be 't'
Now the equation will be
t + 3:45 = 11:20 am
t = 11:20 - 3:45
t = 7 : 35 am
Before 3.75 hours of 11:20 am it will be 7:35 am.
The equation would be 3.75+t=11.2 so:
3.75+t=11.2
3.75+t-3.75=11.2-3.75
t=7.45, which is 7:35.

Answer:
The height of the hovercraft at the time of takeoff is 33 meters.
Step-by-step explanation:
Height of hovercraft x seconds after takeoff = h(x) = -(x - 11)(x + 3)
Height after takeoff is = h(0) = -(0 - 11)(0 + 3) = -(-11)(3) = 33
So the correct answer is 33 meters. The height of the hover craft at the time of the takeoff is 33 metres.
Answer: 33 meters.
