We notice it diviides by 3 each time or multiplies by 1/3
common ratio is 1/3
first term is 648
so next 3 terms are 8, 8/3, and 8/9
rule is an=648(1/3)^(n-1)
Answer:
r = 1
Step-by-step explanation:
In this question, we have to solve for the vallue of "r". We will use the distributive property shown below to ease our process.
Distributive Property:
a(b+c) = ab + ac
Now, lets solve this:

As we have seen the value of r is "1"
Answer:
1.61428571429
Step-by-step explanation:
That would be about 1.62. You do 3 5/7-2 1/10. That would equal to 1.61428571429.
We want to find miles per hour.
Speed is distance over time.
So take 10 miles (distance) / 3 hours (time)
This is the same as 10/3.
10/3 = 3 and 1/3
Therefore, the girl is going 3 and 1/3 miles per hour.
