In 2014, the estimated population of the world was 7,261,087,766 people. when this number is written in expanded form using exponents, one power of 10 would not be represented. which power of 10? why?

we are given

In 2014, the estimated population of the world was 7,261,087,766 people

we know that

7,261,087,766 lies between 7,300,000,000 and 7,200,000,000

but it is more closer to 7,300,000,000

so, we will consider this for scientific form

we can also write as

scientific form is

..............Answer

The power of 10 which is not represented would be because it is multiplied by 0.    

Step-by-step explanation:

Given : In 2014, the estimated population of the world was 7,261,087,766 people.

To find : When this number is written in expanded form using exponents,one power of 10 would not be represented.which power of 10? Why?

Solution :

First we write the number expanded form using exponents,

Number 7,261,087,766

If we multiply zero the number get vanished,

So, The power of 10 which is not represented would be because it is multiplied by 0.

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

other answer is correct. i had used the radius of the radius somehow. a website:
