the 20x(8+2) is just two times greater as its 200 instead of 100 which is the other answer
My graphing calculator says g(4) = f(2).
The 4th selection, x=4, is appropriate.
Answer:
64.6 km/h
Step-by-step explanation:
18:14 = 18h 14'
1h = 60'
18h = 17h + 60'
18h14' = 17h + 60' ´14' = 17h 74'
then:
17h 74'
-17h 22'
= 0h 52'
the train travelled 56km at 52 minutes
56km/52minutes
1 hour = 60 minutes
52 minutes = 52/60 = 0.86667 hours
then:
56km/52minutes = 56km/0.86667hours
= 64.615 km/hours
Percent means per 100
multiply .015 x 100 (move decimal point 2 places to the right(
answer is 1,5%
hope this helps
