Suppose an average person blinks 15 times per hour. How many times does an average person blink in a year? Write the answer in scientific notation (Hint: 1 year = 365 days, 1 day = 24 hours).
To find the number of times an average person blinks in a year, we can multiply the number of blinks per hour by the number of hours in a day and then by the number of days in a year.
Number of blinks per hour = 15
Number of hours in a day = 24
Number of days in a year = 365
Total blinks in a year = 15 blinks/hour * 24 hours/day * 365 days/year
= 131,400 blinks/year
Writing this in scientific notation, we move the decimal point 4 places to the left:
= 1.314 × 10^5 blinks/year

To find the number of times an average person blinks in a year, we need to calculate the number of blinks in an hour and then multiply it by the number of hours in a year.
Given that an average person blinks 15 times per hour, we can calculate the number of blinks in a year as follows:
15 blinks/hour × 24 hours/day × 365 days/year
= (15 × 24 × 365) blinks/year
= 131,400 blinks/year
In scientific notation, this is written as:
1.314 × 10^5 blinks/year
To find the number of times an average person blinks in a year, we need to multiply the number of blinks per hour by the number of hours in a year.
Given that an average person blinks 15 times per hour, we can calculate the number of blinks in a year as follows:
Number of blinks per year = Number of blinks per hour × Number of hours in a year
Number of hours in a year = 365 days × 24 hours/day (since there are 365 days in a year and 24 hours in a day)
Let's calculate it:
Number of blinks per year = 15 blinks/hour × 365 days × 24 hours/day
= 15 × 365 × 24 blinks/year
= 131,400 blinks/year
To write the answer in scientific notation, we represent it in the form of A × 10^B, where A is a number between 1 and 10, and B is the exponent.
In this case, the answer is 1.314 × 10^5 blinks/year.
Therefore, an average person blinks approximately 1.314 × 10^5 times in a year.
