Answer:
2.2 ft ( to 1 dec. place )
Step-by-step explanation:
The arc length is calculated as
arc = circumference × fraction of circle
= 2πr × 
= 2π × 7 × 
= 14π ×
= 
≈ 2.2 ft
Shared ratio is 5 : 8
Total parts
5+8 = 13
If we want to get a single part, it has to be divided by 13.
390 / 13 = 30
therefore,
5 : 8
1*5 : 1*8
30*5 : 30*8
150 : 240

Step-by-step explanation:
The system of equations that Sam can use is given by:
A 13b + 4t =327.50, 6b + 2t = 142.96
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable b: Cost of a bush.
- Variable t: Cost of a tree.
The first order was for 13 bushes and 4 trees, and totaled $327.50, hence:
13b + 4t = 327.50.
The second order was for 6 bushes and 2 trees, and totaled $142.96, hence:
6b + 2t = 142.96.
Which means that option A is correct.
