andrezito [222]

The population of California = $2.52 \times 10^7$ people.

Land area of California = $4.05 \times 10^5km^2$ .

We have to determine the average number of people per square kilometer.

Average number of people per square kilometer =

Land area of California $\div$ Population of California

= $4.05 \times 10^5 \div 2.52 \times 10^7$

= $1.6 \times 10^{-2}$

Therefore, the average number of people per square kilometer is $1.6 \times 10^{-2}$ .

How to evaluate 11+y

s344n2d4d5 [400]

Good morning ☕️

Step-by-step explanation:

11+y is an expression that contains a variable ‘y’

then its value depends on ’y’

examples :

if y = 0 → 11+y = 11+0 = 11

if y = 1 → 11+y = 11+1 = 12

if y = 2 → 11+y = 11+2 = 13

and so on.
