Answer:
Step-by-step explanation:
original price = 20
Answer:
A. 4.8°
Step-by-step explanation:
We have that,
The horizontal distance for the ramp = 12 feet.
Maximum height of the ramp = 1 feet.
So, we get that the value of the angle 'x' made by the ramp with the ground is given by,

i.e. 
i.e. 
i.e. 
i.e. x = 4.8°
Thus, the maximum angle made by the ramp with the ground is 4.8°.
Answer:
C. x<27 and x>-3
Step-by-step explanation:
[x-12]<15
-15<x-12<15
-15+12<×<15+12
-3<×<27
x>-3 and x<27
The bike is now $500. The price goes down by 20% each year.
500(0.20) = 100
The bike decreases by $100 each year.
After 5 years at $100 less per year, the bike will be $0.00.
Step-by-step explanation:
5v - 5 < 5
Add 5 on both sides
5v - 5 + 5 < 5 + 5
5v < 10
Divide by 5 on both sides
V < 2
