Question

there are about 2.5x10^10 red blood cells in an average adult. About how many adults would it take to have a total of 1 googol red blood cells

Answer 1

A googol is 10 raised to the power 100 i.e. 10¹⁰⁰

Number of RBCs in an average adult = 2.5x10¹⁰

Number of adults required for 1 googol red blood cells = 10¹⁰⁰ ÷ 2.5x10¹⁰

⇒  Number of adults required for 1 googol red blood cells = 10¹⁰¹ ÷ 25x10¹⁰

⇒  Number of adults required for 1 googol red blood cells = 100x10⁹⁹ ÷ 25x10¹⁰

⇒  Number of adults required for 1 googol red blood cells = 4x10⁸⁹

Hence, 4x10⁸⁹ adults are required to have a total of 1 googol red blood cells

Answer 2

Answer:

It take ${4\times 10^{89}$ adults to have a total of 1 googol red blood cells.

Step-by-step explanation:

Consider the provided information.

1 googol is $1\times 10^{100}$

It is given that there are about $2.5\times 10^{10}$ red blood cells in an average adult.

To find how many adults  would it take to have a total of 1 googol red blood cells divide the 1 googol with $2.5\times 10^{10}$ .

$\frac{1\times 10^{100}}{2.5\times 10^{10}}$

$\frac{1\times 10^{100-10}}{2.5}$

$\frac{1\times 10^{90}}{2.5}$

$\frac{10\times 10^{89}}{2.5}$

${4\times 10^{89}$

Hence it take ${4\times 10^{89}$ adults to have a total of 1 googol red blood cells.
