Answer:
y=25h-2000
Step-by-step explanation:
you would need to subtract the 2000 in order to know when you made a profit from buying the piano. and then the 25h is the amount of hours teaching.
Step-by-step explanation:
4+5/6*3/10
29/6*3/10
=87/60
=29/20
=1 9/20
Answer:
t = 9.58 s
Step-by-step explanation:
Given that,
The height from where the cell phone is dropped, h = 450 feet
We need to find the time for the cell phone to reach the ground. Let the time be t. Using second equation of kinematics to find it.
u is initial velocity, u = 0
a = g
So,
So, it will take 9.58 seconds to reach the ground.
I think the answer is the second one. The formula is suppose to be constant/the same for when finding the whole area of the whole shape.
