Question

A scientist work out that a human blinks approximatly 8 x 10⁶ times per year. Use this value to calculate approximatly how much times a human blinks in three years. Give your answer in standard form.

Answer 1

To calculate the number of blinks in three years, multiply the yearly blinks (8 x 10⁶) by three, resulting in 24 x 10⁶ blinks, which is 2.4 x 10⁷ blinks in standard form.

Step-by-step explanation:

The question asks us to calculate approximately how many times a human blinks in three years, given that they blink approximately 8 x 10⁶ times per year. To find the number of blinks in three years, we multiply the number of blinks in one year by three:

1. Multiply the given amount of blinks per year by 3 to account for three years: 8 x 10⁶ blinks/year x 3 years.
2. Perform the multiplication: (8 x 3) x 10⁶.
3. The result is 24 x 10⁶ blinks.

So, in standard form, a human blinks approximately 2.4 x 10⁷ times in three years.
