Rate of change is used to mathematically describe the percentage change in value over a defined period of time. (I looked that up)
So the rate of change is the slope and slope is the ratio of change between any 2 points on a line.
Slope measures the steepness of a line.
Slope is the ratio of the vertical change, called the rise, to the horizontal change called the run between any 2 points on the line.
Slope is written as a fraction in simplest form. 5/10=1/2
Variable for slope: M.
Reply for any more questions, also sorry for a slow response. I thought a lot.
Answer:
1
Step-by-step explanation:
the tenths place is the number right behind the decimal so it be 9
look next door if its 5 or more round next door, 4 or less kill the rest
ex) .8937 rounded to the 10ths = .9
Answer is C 41/20 inches
Monday 3/10
Tuesday twice as Monday: 3/10 * 2 = 6/10
Wednesday: 1/4
Thursday: 1/2
Friday: 2/5
Total: Monday + Tuesday + Wednesday+Thursday + Friday
= 3/10 + 6/10 + 1/4 + 1/2 + 2/5
= 6/20 + 12/20 + 5/20 +10/20 +8/20
=41/20
8.5 * x = 5
5 / 8.5
Approximately 10/17
