e used. One milliliter of blood contains approximately 5 million red blood cells, and one pint is about 473 milliliters. Create and solve an equation that can be used to find approximately how many red blood cells are in a pint of blood. Use scientific notation for the first box of the equation. × 2.4 × 109 9.73 × 106 2.4 × 106 5 × 106 473 4.73 5 × 109 + ÷ – 9.73 × 109

5.0 x 10^6 X 473 = 2.4 x 10^9

There are 5 x 10^6 blood cells in a ml, and 473 ml in a pint. simply multiply both numbers together and put the answer in scientific notation (one digit before the decimal)

Answer : The correct answer is, 2.63\times 10^{11}

Step-by-step explanation :

Scientific notation : It is the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.  The numerical digit lies between 0.1.... to 9.9.....

For example :

5000 is written as 5.0\times 10^3

889.9 is written as 8.899\times 10^{-2}

In this examples, 5000 and 889.9 are written in the standard notation and 5.0\times 10^3  and 8.899\times 10^{-2}  are written in the scientific notation.

As we are given the following conversions:

1mL=5\times 10^6RBC

1\text{ Pint}=437mL

Now we have to calculate the number of RBC present in a pint of blood.

As, 1mL=5\times 10^6RBC

and, 1\text{ Pint}=437mL

So, 437mL=\frac{437mL}{1mL}\times 5\times 10^6RBC=2365\times 10^6RBC=2.4\times 10^9RBC

Hence, the correct answer is, 2.4\times 10^9RBC

Answer: exponential

Step-by-step explanation:

its exponential

count the squares in each one

first is 2 squares

second is 4 squares

third is 8 squares

this is going up exponentially because the first one would be 2^1 the second would be 2^2 and the third would be 2^3
