Given:

Consider the population of California = 3.9\times 10^7

Consider the population of Maine = 1.3\times 10^6

To find:

The difference between the population of California and Maine.

Solution:

We have,

Population of California = 3.9\times 10^7

Population of Maine = 1.3\times 10^6

Difference between the population of California and Maine is

\text{Difference}=3.9\times 10^7-1.3\times 10^6

\text{Difference}=3.9\times 10^7-(0.13\times 10)\times 10^6

\text{Difference}=3.9\times 10^7-0.13\times 10^7

\text{Difference}=(3.9-0.13)\times 10^7

\text{Difference}=3.77\times 10^7

Therefore, the correct option is D.

1. C

2. B

3. B

Step-by-step explanation:

Vertical angles are the angles opposite each other when two lines cross, thus angles with measures (x+77)° and 126° are vertical angles.

Vertical angles are congruent.

Hence,

x+77=126\\ \\x=126-77\\ \\x=49^{\circ}
