In bioligy class cher is viewing cells with a microscope. cell h measures 8.76x10^-3 microns in diameter and cell v measures 2.1

3241004551 [841]

Answer:

Larger cell 400 times bigger cell than the smaller cell

Step-by-step explanation:

Given:

diameter of the cell h = $8.76\times10^{-3}$

diameter of the cell v = $2.19 \times10^{-5}$

To Find:

How many tines larger is the bigger cell than the smaller cell?

Solution:

The cell h with diameter $8.76\times 10^{-3}$ is larger and the cell v with diameter $2.19 \times 10^{-5}$ is small. To find the number of times it is larger, we can divide the larger cell diameter by smaller cell diameter

=> $\frac{8.76\times 10^{-3}}{2.19 \times 10^{-5}}$

=> $\frac{8.76\times 10^ {-3} \times 10^{5}}{2.19 }$

=> $\frac{8.76\times 10^ {(-3+5)}}{2.19 }$

=> $\frac{8.76\times 10^2}{2.19 }$

=> $\frac{876}{2.19}$

=> 400

Larger cell is the bigger cell than the smaller cell by 400 times
