The answer is =
4/45
(Decimal: 0.088889)
The equation is in the format
where a is the initial value (when t=0), b is the rate of change between terms, and t is the amount of time.
Our initial value is 100. We find the rate of change by first finding the percent of change:
amount of change/original amount
= 20/100 = 0.2
This is a percent decrease, so we will subtract it from 1:
1-0.2 = 0.8
This goes in for b.
Answer:
3(r-1)(3r-2)(3r+2)
Step-by-step explanation:
So, 3 goes into 8 2 times and 2 will be left over so you would put:
2 2/8 or 2 1/4
