Answer 1

Answer:

A. Total area of Alaska is considerable larger than total area of Connecticut.

B. Population of California is considerably larger that population of Alaska.

Step-by-step explanation:

A. What is the difference in total area of Alaska and Connecticut?

According to the US government, total areas of Alaska and Connecticut are 663,268 square miles ($6.633\times 10^{5}$ square miles) and 5,567 square miles ($5.567\times 10^{3}$ square miles), respectively.

The difference between both quantities is:

$x = 6.633\times 10^{5}\,mi^{2}-5.567\times 10^{3}\,mi^{2}$

$x = 6.577\times 10^{5}\,mi^{2}$

Which means that total area of Alaska is considerable larger than total area of Connecticut.

B. What is the difference in total population of California and Alaska?

According to the US government, total populations of California and Alaska are 39,512,223 people ($3.951\times 10^{7}$ people) and 710,249 people ($7.103\times 10^{5}$ people), respectively.

The difference between both quantities is:

$x = 3.951\times 10^{7}\,people - 7.103\times 10^{5}\,people$

$x = 3.880\times 10^{7}\,people$

Which means that population of California is considerably larger that population of Alaska.
