Answer 1

Let's do the calculations:

An average person blinks 15 times per hour.

1 day = 24 hours

Blinks per day = 15 blinks/hour × 24 hours/day = 360 blinks/day

1 year = 365 days

Blinks per year = 360 blinks/day × 365 days/year

Now, let's calculate:

360 blinks/day × 365 days/year = 131,400 blinks/year

To write this in scientific notation, we need to express it as a number between 1 and 10 multiplied by a power of 10.

131,400 = 1.314 × 10^5

This is because 131,400 can be rewritten as 1.314 × 100,000, and 100,000 is 10 to the power of 5.

The correct answer is:

1.314 × 10^5
1.314 times 10 superscript 5 baseline
