<span>Anna learns in her science class that the human eye blinks an average of 4,200,000 times a year. What is this number expressed in scientific notation?</span>
Answer:
8/3ft
Step-by-step explanation:
To find how high she would bounce, we need to first understand that her height of each jump would be multiplied by 2/3 given that each bounce afterwards is two thirds as high as the bounce before.
We can then set the equation:
6 x 2/3 x 2/3
=6 x (2/3)^2
=8/3
Therefore the answer is 8/3 ft.
Hope it helps!
