Assume that an average cell has a diameter of

emmasim [6.3K]

Given that the volume of a cell is 50 cubic micrometers. It says to find the number of cells present in 1 cubic centimeter.

So we need to first convert the units of volume of a cell, then we can find the total number of cells in 1 cubic centimeter.

We know 1 meter = 100 centimeters = 1000000 micrometers

So 1 centimeter = 10000 micrometers

Taking Cubic powers on both sides :-

1 cubic centimeters = 10¹² cubic micrometers

1 cubic micrometers = 10⁻¹² cubic centimeters

50 cubic micrometers = 50 × 10⁻¹² = 5 × 10⁻¹¹ cubic centimeters

So volume of one cell = 5 × 10⁻¹¹ cubic centimeters

Number of cells = $\frac{Total\;\; volume}{Volume\;\; of\;\; one\;\; cell} = \frac{1\;cm^{3}}{5 * 10^{-11}\;cm^{3}} = \frac{10^{11}}{5}$ = 2 × 10¹⁰ cells.

So, total number of cells = 2 × 10¹⁰ cells.

Divide: –65.86 ÷ (–7.4)

Rina8888 [55]

Answer:

8.9

Step-by-step explanation:

The answer is 8.9 because two negatives divided by each other equals a positive. In this case, there are two negatives so you know the answer will be a positive. In the end when you divided –65.86 ÷ (–7.4), you get 8.9!

Hope this helps, have a good day. c;

(You can also type it into your calculator if you have one, and you should hopefully get the same answer.)
