Answer: 806.72 full rotations.

Step-by-step explanation: There are 5,280 ft in a mile (a good thing to have memorized) multiply that by 12 to find inches. 5280*12 = 63360. Then we divide this by the circumference of the circle. C = 2πr. The radius is half the diameter so C = dπ. 25π = 78.54. Then we divide 63360/78.54 = 806.72 rotations.

Borrow 1 from the whole number to rewrite 8 10/24.

koban [17]

Answer:

A. $7\frac{34}{24}$

Step-by-step explanation:

We are given the expression, $8\frac{10}{24}$

On re-writing the expression after borrowing 1, we have,

$8\frac{10}{24}$ = $7(\frac{10}{24}+1)$

i.e. $8\frac{10}{24}$ = $7(\frac{10}{24}+\frac{24}{24})$

i.e. $8\frac{10}{24}$ = $7\frac{34}{24}$

Thus, the equivalent expression after borrowing 1 from the given expression is $7\frac{34}{24}$ .

Hence, option A is correct.
