Sergeu [11.5K]

Answer:

Mina took 2,986 steps on the third hour.

Step-by-step explanation:

With the information provided, you know that Mina took a total of 9,245 steps in three hours and as you know the quantity of steps she took on the first and second hour, you can subtract the steps she took on the first and second hour from the total amount of steps to determine the steps she took on the third hour:

9,245-2,387-3,872=2,986

According to this, the answer is that Mina took 2,986 steps on the third hour.

A side of a square is 8 3/2  inches. Using the area formula A = s2, determine the area of the square.
Sedaia [141]
We are given that:
side length = 8 3/2 inches = 9.5 inches
the rule for the area is: A = s^2

Substitute with the side length in the rule given to get the area as follows:
Area = s^2 = (9.5)^2 = 90.25 inch^2
