The earth is approximately circular in cross section, with a circumference at the equator of 24 comma 882 miles. suppose two ropes are used to create two concentric circles: one by wrapping a rope around the equator and another using a rope 48 ft longer than the first rope. how much space is between the two ropes?

1. find the radius of the equator. You know that the formula for the circumference is , then

mi.

2. If you are using a rope 48 ft=0.0091 mi longer than the first rope (then the circumference is 24882.0091), then you obtain another radius:

mi.

3. The difference between radii is 3,962.103359-3,962.101910=0.001449 mi (similarly 7.65 ft)

b) the dogs need to shift their focus to human scent.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
