Estimates of the number of cells in the human body vary over an order of magnitude. Indeed, the precise number varies from one

Amiraneli [1.4K]

Answer:

a) 2.00 × 10¹⁰; b) 2.00 × 10¹³

Step-by-step explanation:

a) No. of cells in 1 cm³

$\text{No. of cells} =\text{1 cm}^{3} \times\left( \dfrac{\text{1 m}}{\text{100 cm}}\right )^{3} \times \left (\dfrac{1 \, \mu \text{m} }{10^{-6}\,\text{ m}}\right )^{3} \times \dfrac{\text{1 cell}}{\text{50 $\,\mu$m}^{3}} = \mathbf{2.00 \times 10^{10}} \textbf{ cells}$

b) No. of cells in 1 L

$\text{No. of cells} = \text{1 L} \times \dfrac{\text{1000 cm}^{3}}{\text{1 L}} \times \dfrac{2 \times 10^{10} \text{ cells}}{\text{1 cm}^{3}} = \mathbf{2.00 \times 10^{13}} \textbf{ cells}$

weeeeeb [17]

Answer:

Option 3rd is correct

No,

she should have added $6^2$ and $8^2$ and compared that to $10^2$

Step-by-step explanation:

In a right angle triangle, we use Pythagorean theorem.

Pythagorean theorem states that

the sum of the squares of two sides must equal the square of the third side(the side facing the right angle).

i.e, $\text{Hypotenuse side}^2=\text{sum of the square of two side}$

Given a triangle with side lengths 6, 10, and 8.

If we square all the given sides, we get;

$6^2 = 36$ ,

$8^2 = 64$

$10^2=100$

It can be seen that the sum of 36 and 64 is 100

⇒ $6^2+8^2 = 10^2$

which satisfies the Pythagorean theorem.

⇒ The triangle is right-angled with the side lengths 6 units and 8 units forming the right angle and the side length 10 units being the hypotenuse.

Therefore, her answer is incorrect, she should have added $6^2$ and $8^2$ and compared that to $10^2$
