Answer:
One of my favorite examples is in starting a fire. You can't just hold a match to a log and expect it to work, even though the log and small twigs are the same material and have the same burning point. A cluster of small twigs and splinters bunched up together has a huge surface area compared to a log.

Answer:
14.29% probability that Marlon's friend will think of the number 9
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem, we have that:
There are 7 numbers from 5 to 11(5,6,7,8,9,10,11)
9 is one of them
So
14.29% probability that Marlon's friend will think of the number 9
Answer:
True
Step-by-step explanation:
Answer:
(k + 9)(k - 8)
Step-by-step explanation:
Given
k² + k - 72
Consider the factors of the constant term ( - 72) which sum to give the coefficient of the k- term ( + 1)
The factors are + 9 and - 8, since
9 × - 8 = - 72 and 9 + 8 = + 1, hence
k² + k - 72 = (k + 9)(k - 8)
