In mid-2016, the world's population was about 7.4 billion people. The land area of the state of California is about 163,696 square miles.
If in mid-2016, all the world's people were put into California, what would be the population density of California in people per square mile? Round your answer to the nearest thousand
X people per square mile

the population density of California is 45000 people per square mile

Step-by-step explanation:

The formula for determining population density is expressed as

Population density = number of people/land area

In mid-2016, the world's population was about 7.4 billion people. The land area of the state of California is about 163,696 square miles.

If in mid-2016, all the world's people were put into California, the population density of California would be

7.4 × 10^9/163696 = 45205.747

Rounding up to the nearest thousand people per square mile, it becomes

45000 people per square mile

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
