Question

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 1

`0.00851=8.51* 10^(-3)` cm.

Explanation:

We have been given that the average human body cell is about
`5.1*10^(-4)` cm in diameter. The diameter of a plant cell is
`8*10^(-3)` 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.

`5.1*10^(-4)=0.00051`

`8*10^(-3)=0.008`

`\text{The combined diameter of body cell and plant cell}=0.00051+0.008`

`\text{The combined diameter of body cell and plant cell}=0.00851`

Let us convert our answer in scientific notation.

`\text{The combined diameter of body cell and plant cell}=8.51* 10^(-3)`

Therefore, the combined diameter of the body cell and plant cell is
`0.00851=8.51* 10^(-3)` cm.
