a)
his income must be "x" which is the 100%, and we would know that 0.2% of that is 12.37.

b)
his income must be "x" which is the 100%, and we would know that 2% of that is 12.37.

btw he's not making much either way.
It takes 40 minutes more going up or 40/60 = 0.67 hours
more.
Let us say that:
t = the time required for him running down
t + 0.67 = time required for him running up
Since the distance of running up and down must be equal
therefore:
(3 miles / hr) * (t + 0.67) = (5 miles / h) * t
3 t + 2.01 = 5 t
2 t = 2.01
t = 1.005 hr
So the total length of the hike is:
length = 2 * (5 miles / hr) * (1.005 hr)
<span>length = 10.05 miles</span>
Answer:

Step-by-step explanation:
Let
h(t) ---> the height of an object in meters
t ----> the time in seconds
we have

For t=6 sec
substitute in the quadratic equation the value of t and solve for h


Day Sis you
1 -30 20
2 0 40
3 30 60
4 60 80
5 90 100
6 120 120
So day 6.
I think it is -2, if that helps
