Answer:
50 minutes
Step-by-step explanation:
10 / 0.2 = 50
It takes 5 minutes for the snail to travel 1 inch, multiply that by 10 and we get 50 minutes.
Yes.
8/20 = 6/15 = 4/10 = 2/5

Answer:
Step-by-step explanation:
For these we always want to see how much each term is decreasing by, this will tell us what kind of series it is.
-40, -47, -54, -61
Each time it DECREASES by -7, so it is an arithmetic sequence
The explicit form is found with two parts. the start and how much each term changes by. The start is -40 and the change is -7, so the explicit formula is -40 - 7(n-1). This is assuming the first term is a_1. If you are starting with a_0 instead you want to make (n-1) be n. so if a_0 = -40 then you have -40 - 7n but if -40 = a_1 then you have -40 - 7(n-1)
the next one has a "common difference" of 30. so now if -8 is a_0 you have -8 + 30n but if -8 is a_1 then you have -8 + 30(n-1)
If the Eagles start with 48 yards left then gain 31, you would subtract 31 from 48. So 48-31=17. So they had 17 yards to go. On the next four plays the lose yards, so add up all the yards lost in those four plays. 3+5+7+4 which equals 19. So they were 17 yards away but then they lost 19 yards so you would add 17 and 19, which gives you 36. So therefore the ball is 36 yards away from the goal line after those five plays.
