Step-by-step explanation:
Step one:
we are given the equation for Addy And Rachel's earning as
-------------1
Step two:
Context creation
Say john earns $0.9 per paper he delivers, estimate how much he would earn to deliver 10 papers
let the amount earn be y and the number of papers delivered be x
the equation is
y=0.9x
for x=10
y=0.9(10)
y=$9
<u>We can see that John's unit rate is more than Addy's unit rate</u>
Answer:
I think it is 45.
Step-by-step explanation:
The formula for a finite geometric series is:
a₁ is the first term of the geometric series. From the given series we can see that the first term of the series is 16.
r is the common ratio of the series. r can be found by dividing a term by its previous term. so r for the given series will be:
r = 24/16 = 3/2
n is the number of terms in the series. We can use the general formula of a Geometric Series to find the number of terms in the given series:
We want to find at which number in the series is 81 located. Using the values, we get:
This means, there are 5 terms in the given series.
Using the values in the formula, we get:
This means, the sum of given geometric series is 211.
