Noelle goes east at N mph.
Karina travels west at N + 9
then their velocity between them is (N + N + 9)
After 8 hours they travel 8(2N + 9) = 232
(2N + 9) = 29
2N = 20
N = 10 mph for Noelle
N+9=19 mph for Karina
P would equal -3/7
Hope it helps!
Answer:
1, 8, 27?
Wasn't sure if you were asking for the cube numbers instead?
Answer:
it has decreased the most in-between day 11 and day 6 because the graph has a little bit of a steeper drop. So there is less snow those days.
Step-by-step explanation:
Derek would have planted the tree 7 years ago. You subtract 36 from 44.75 and get 8.75. This is how much the tree grew since he planted it. Then, you'll divide 8.75 by 1.25 (1 1/4) which tells you how many years it has been since he planted the tree. The final answer is 7 years. Hope this helps!
