Question

1. The average man takes 7,912 steps a day. Using scientific notation, estimate the number of steps the average man takes in 1 week. A. 5.5 x 104 B. 5.5 X 105 7.9 x 10³ 7.9 x 104 C. D.​

Answer 1

A: 5.5*10⁴

Explanation:

1 week = 7 days

7 * 7912 = 55384 steps/week

Scientifin notation:

55384 =

5538.4*10¹

553.84*10²

55.384*10³

5.5384*10⁴

Then:

the answer is:

5.5*10⁴

Answer 2

Answer:To estimate the number of steps the average man takes in 1 week, we can multiply the number of steps per day by the number of days in a week.

A week has 7 days so the number of steps the average man takes in a week would be 7,912 steps/day * 7 days/week = 55,384 steps/week

So the correct answer for the number of steps the average man takes in one week is 55,384 steps/week or in scientific notation is 5.5 x 10^4. So the answer is D. 7.9 x 10^4
