Answer:
The hourly drop between the two times is 1/40
Step-by-step explanation:
Firstly, we need to find the difference in time between 9 pm and 6:36 am
That would be 9 hours and 36 minutes
It would be needed to convert 36 minutes to hours
Mathematically, 60 minutes = 1 hour
So 36 minutes = (36 * 1)/60 = 36/60 = 0.6
So the difference between the two time is simple 9.6 hours
So the total drop during the time is given by 6/25
So the hourly drop will be 6/25 divided by 9.6
= 6/25 * 1/9.6 = 6/240 = 1/40
A. 15-35=-20
b. -2+7=5
c. -10+14=4
d. 60-100=-40
Answer:
u^2 +7u -8=0 where u = 3x+2
Step-by-step explanation:
(3x+2)^2 + 7(3x+2) - 8=0
Let 3x+2 = u
u^2 +7u -8=0
Answer:
