Answer:

\frac{3}{4} miles per hour.

Step-by-step explanation:

The jogging path used by Selma is a loop measuring \frac{3}{4} of a mile.

On a certain Monday, Selma completed the loop in an hour.

Thus, by applying the common denominator technique, Selma's running rate in miles per hour will be

\frac{3}{4} \div 1 = \frac{3}{4} \div \frac{4}{4} = \frac{3}{4} miles per hour.

The unit for this measurement is mph, or miles per hour. (Answer)

The shoe store manager borrowed $17,000.00 from the bank to purchase 1000 pairs of shoes. The bank charges a simple interest rat
babunello [11817]

Answer:

2550

Step-by-step explanation:

1) The initial amount borrowed is 17,000.

2) The interest rate is set at 5%.

3) Therefore, to calculate interest: 0.05 * 17000 equals 850.

4) Since the repayment takes 3 years, multiply by 3: 850 * 3 equals 2550.

5) Thus, the total interest that the shoe store is obligated to pay is 2550.
