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

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
