Answer:

Step-by-step explanation:
The computation of the thickness of tire rubber for every lost 1,000 driven is shown below:
Data provided in the question
Inches of tread = 
In case of replaced = 
Based on the above information
Now in 40,000 miles, the ratio is

And for every 1,000 miles driven, the thickness is

hence, the thickness of tire rubber is 
0.18 is bigger because it is closer to 1 and 0.8 is closer to 0
Answer:
y = 4
Step-by-step explanation:
y = (1/2)x + 1
when x = 6
y = (1/2)(6) + 1
y = 3 + 1
y = 4
Answer:
23
Step-by-step explanation:
A+B+C = 180
62+95+Z = 180
157 + Z = 180
Z = 23
