The time for the job for which the two company are the same is 16 
<h3>How to form the equation and find the cost?</h3>
A yard cleanup service charges a $345 fee plus $16.25 per hour. Therefore,
using linear equation,
y = mx + c
where
Therefore,
y = 345 + 16.25x
Another cleanup service charges a $213 fee plus $24.50 per hour. Therefore,
y = 213 + 24.50x
Hence, the time when both cost are the same is as follows;
213 + 24.50x =  345 + 16.25x
213 - 345 = 16.25x - 24.50x
-132 = -8.25x
x = 132 / 8.25
x = 16

Answer:
im not sure what you are asking
Step-by-step explanation:
 
        
             
        
        
        
45° is exactly 1/8 of a full circle (45/360 = 1/8) <span>
So the length of the arc would be 1/8 of a full circumference: 
C = 2π r 
C = 2π(8) 
C = 16π 
Take 1/8 of this: 
1/8C = (1/8)16π = 2π 
Answer: 
Exact answer --> 2π inches 
(Approx. answer --> 6.28 inches)</span>
