The size of a cell is typically found by capturing an image under a microscope then
using software to measure its diameter. Two cells are measured using this method:
Cell M: 7.65 x 10-3 centimeters
Cell N: 9.1 x 10-4 centimeters
What's the difference between the diameters of the two cells? Express your answer
using scientific notation.

Answer:

The difference is 6.74 * 10^-3 centimeters

Step-by-step explanation:

Firstly, we need to write the numbers as they would occur normally

we have this as;

7.65 * 10^-3 = 0.00765

9.1 * 10^-4 = 0.00091

So by subtracting, we have it that we subtract the value of the diameter of the cell N from that of the cell M since it is a bigger number

we have this as;

0.00765 - 0.00091 = 0.00674 and in scientific form is 6.74 * 10^-3 centimeters

The relationship between the length and weight of certain sea turtles can be approximated by the equation L = 0,55 W,
where L is the length in feet and W is the weight in pounds. If a sea turtle is 2.5 feet long, which is closest to its weight?

This past winter, 643 flamingos migrated to Gordon Lake. A researcher states that the number of flamingos migrating to the lake is decreasing by 12 birds every year. Which of the following represents the number of flamingos, n, that will migrate to the lake t winters from last winter if the researcher’s trend continues? A. t = 643 - 12n B. n = 643 - 12t C. t = 12 - 643n D. n = 12 - 643t
