PLEASE PLEASE HELP

The average human body cell is about 5.1 x 10^-4 cm in diameter. The diameter of a plant cell is 8 x 10^-3 cm.
What is the combined diameter of the body cell and plant cell?

Answer:

[tex]0.00851=8.51\times 10^{-3}[/tex] cm.

Step-by-step explanation:

We have been given that the average human body cell is about [tex]5.1\times10^{-4}[/tex] cm in diameter. The diameter of a plant cell is [tex]8\times10^{-3}[/tex] cm.

To find the combined diameter of the body cell and plant cell, we will add both diameters.

First of all let us convert our given diameters in standard notation.

[tex]5.1\times10^{-4}=0.00051[/tex]

[tex]8\times10^{-3}=0.008[/tex]

[tex]\text{The combined diameter of body cell and plant cell}=0.00051+0.008[/tex]

[tex]\text{The combined diameter of body cell and plant cell}=0.00851[/tex]

Let us convert our answer in scientific notation.

[tex]\text{The combined diameter of body cell and plant cell}=8.51\times 10^{-3}[/tex]

Therefore, the combined diameter of the body cell and plant cell is [tex]0.00851=8.51\times 10^{-3}[/tex] cm.
