Estimate the number of breaths taken by a human being during an average lifetime. (we estimate an average respiration rate of about 10 breaths per minute and a typical life span of 70 years.) 106 breaths 108 breaths 1010 breaths 1012 breaths 1014 breaths

In this question, we have to estimate the number of breaths taken by a human being during an average life time .

And average respiratory rate of about 10 breaths per minute . And average age of a human being is 70 years .

In 1 minute, number of breaths are 10 breaths .

So in 1 day,number of breaths are

And for one year, it is

And in 7 years, it is

i think this could be a possible answer (1 / 84) -1

good luck! : d

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
