WILL MARK BRAINLIST!!​
nignag [31]

Answer:

24 units

Step-by-step explanation:

Look at the coordinate plane. First start with the bottom side (LN). The line goes from -3 to 9. This means that the line is 12 units long. Now, look at the other sides. MN goes from 3 to 9, therefore, the line is 6 units long. Lastly, look at ML— -3 to 3, therefore, the line is 6 units long. Add them all up, (12+6+6) and it equals 24 units.

The population of a country was estimated to be 1.114 x 10^8. On this day, the population of the world was 3.853 x 10^9.
Lelechka [254]

Step-by-step explanation:

To find how many people lived outside of the country we subtract:

3.853 × 10^{9} - 1.114  × 10^{8}  = 3.7146 ×

To find the percentage of people living inside the country, we divide:\frac{1.114 x10^{8}}{3.853 x10^{9}} =2.8913x10^{-2} percent or 2.89%.  Which is extremely small.
