In a recent year, the population of California was about 2.52 x 10^7 people. Its land area is about 4.05 x 10^5 km^2. What was t

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

It is represented in scientific notation as Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

Identify an equation that models the situation and find its solution. Kane planned to build a 53-centimeter-tall model of a buil

alex41 [277]

Answer:

The increment in the model is 106cm

Step-by-step explanation:

Given

$Initial\ Height = 53cm$

$Final\ Height = 159cm$

Required

Determine the increment

To do this, we simply subtract the initial height of the building from the final height

$Increment = Final\ Height - Initial\ Height$

$Increment = 159cm - 53cm$

$Increment = 106cm$

<em>Hence, the increment in the model is 106cm</em>
