$8.25x2=$16.50
$5x2=$10
$10+$16.50=$26.50
2x$20=$40
$40-$26.50=$13.50
The sum expressed in sigma notation is .
Solution:
Given series is 22 + 27 + 32 + 37 + 42 + 47.
Write it in the sequence form 22, 27, 32, 37, 42, 47.
First term of the sequence = 22
Common difference = 27 – 22 = 5
This is arithmetic sequence.
term of the arithmetic sequence is
In the given series number of terms is 6.
So n = 1 to 6.
Write n = 1 in the lower of the sigma and 6 in the top of the sigma.
The sum expressed in sigma notation is .
It will take more than 60 miles depending on how long the home plate is
Answer: 3:1
Step-by-step explanation:
From the question, we are informed that a gear ratio is the ratio of the teeth on the front sprocket and the teeth on the rear sprocket.
We are further told that the bike has 36 teeth on the front sprocket and 12 teeth on the rear sprocket.
Based on the explanation given in the question, the gear ratio for the bike would be the ratio of 36 to 12. This will be:
= 36:12
Since 12 is a common factor. It can be further reduced to 3:1.
Therefore, the gear ratio is 3:1
