A local library claims it has 2.73x103 books. If there are 42 people in the building, how many books per capita are there?
Marizza181 [45]

Answer:

63 books per capita in the library

<em></em>

Step-by-step explanation:

Given

Books = 2.73 * 10^3

People = 43

Required

Determine the book per capita

To do this, we simply divide the number of books by number of person;

Average = \frac{Books}{People}

Average = \frac{2.73 * 10^3}{43}

Average = \frac{2.73 * 1000}{43}

Average = \frac{2730}{43}

Average = 63.488372093

Average = 63 (Approximated)

Hence;

<em>There are 63 books per capita in the library</em>

A meteor crater is 4100 feet in diameter. Approximate the distance around the crater. Use 3.14 for piπ
Novay_Z [31]
A crater shape should look like a circle. Then, the distance around the crater would be the area of the circle. To answer this question, you need to know how to calculate circle area. Since the diameter is 4100ft and radius is 1/2 of diameter, then the area should be:

Circle area= 2* 3.14 * radius= 2 *3.14 * 1/2 * 4100ft= 12874ft
