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).(1 point)
To find out how many 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 day, multiplied 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
So the total number of blinks in a year = 15 x 24 x 365 = 131,400
In scientific notation, this can be written as 1.314 × 10^5.
To find the number of times an average person blinks in a year, we need to multiply the number of times they blink in an hour by the number of hours in a day, and then by the number of days in a year.
Given that an average person blinks 15 times per hour, we can calculate it step-by-step:
Number of times an average person blinks in an hour = 15 times
Number of hours in a day = 24 hours
Number of days in a year = 365 days
To calculate the total number of blinks in a year, we multiply these values:
15 times/hour * 24 hours/day * 365 days/year
Now, let's calculate it:
15 * 24 * 365 = 131,400
The average person blinks approximately 131,400 times in a year.
Expressed in scientific notation, this would be written as 1.314 × 10^5.
To calculate 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 day and the number of days in a year.
Given:
Blinks per hour = 15
Days in a year = 365
Hours in a day = 24
We can calculate the number of blinks in a year as follows:
Blinks per year = Blinks per hour × Hours in a day × Days in a year
Substituting the given values into the formula:
Blinks per year = 15 × 24 × 365
Evaluating the expression:
Blinks per year = 131,400
To write this answer in scientific notation, we express it as a number between 1 and 10 multiplied by a power of 10.
The number 131,400 can be rewritten as 1.314 × 10^5.
So, an average person blinks approximately 1.314 × 10^5 times in a year.
