Answer:
0.4%.
Step-by-step explanation:
Given that,
The length of a bolt is 4.75 inches and a machinist makes a bolt that is 4.769 inches long.
We need to find the percent error of the bolt’s length. The percentage error in the any value is given by :
So, the percentage error of the bolt's length is 0.4%.

Answer: The point (-10,-20) becomes (-8,-16) & point (15,25) becomes (12,20).
Step-by-step explanation:
When a point (x,y) is dilated by a scale factor k from the origin, then the new points become
The given rule of dilation : (x,y) →(0.8x, 0.8y)
The first point is (-10,-20), so its image will be
So, the point (-10,-20) becomes (-8,-16).
The second point is (15,25), so its image will be
So, the point (15,25) becomes (12,20).
Hence, the point (-10,-20) becomes (-8,-16) & point (15,25) becomes (12,20).

Answer:
About 2.17 feet.
Step-by-step explanation:
Let <em>d</em> represent the diameter of the tire.
Then the circumference of the tire will be:
So, the tire will travel dπ miles after one rotation.
After 775 rotations, the total miles traveled should be 5280 feet. Thus:
Solve for <em>d:</em>

Approximate:
The circumference of the tire should be about 2.17 feet.
