Question

"Every second your body replaces about 2.5 million red blood cells - how many red blood cells get replaced in 30 seconds? Write your answers in both standard form and ordinary form."

Answer 1

In 30 seconds, your body replaces about 75 million red blood cells. This can be written in standard form as 7.5 x 10^7 and in ordinary form as 75,000,000 red blood cells.

Step-by-step explanation:

The human body undergoes a remarkable renewal process, replenishing approximately 75 million red blood cells within a mere 30-second interval.

To calculate this turnover, one multiplies the rate of red blood cell replacement per second, which is 2.5 million, by the duration in seconds, in this case, 30.

Thus, the computation results in 2.5 million x 30, equating to a staggering 75 million red blood cells replaced within the specified timeframe.

Represented in standard form, this quantity is expressed as 7.5 x 10^7 red blood cells, emphasizing the efficiency and scale of this biological phenomenon.

In ordinary form, this numerical value translates to 75,000,000 red blood cells, highlighting the magnitude of the body's continuous and intricate process of red blood cell regeneration in a remarkably short span.
