Answer:

4.04 x 10^0 people/km^2 (x 10^0 is fairly redundant but if the answer is required in standard form then include it)

Step-by-step explanation:

Population Density = Population/Area

= 3.11 x 10^7 / 7.69 x 10^6

= 31,100,000 / 7,690,000

= 3110 / 769

= 4.04

= 4.04 x 10^0

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.

Answer: $20\ cm$

Step-by-step explanation:

The first step to solve the exercise is to make the conversion from meters to centimeters.

Since $1\ m=100\ cm$ , then the dimensions of the wood board in centimeters are:

$Lenght=100\ cm\\\\Width=60\ cm$

Now, you must find the Greatest Common Factor (GCF). The steps are:

- Descompose 100 and 60 into their prime factors:

$100=2*2*5*5=2^2*5^2\\60=2*2*3*5=2^2*3*5$

- Multiply the commons with the lowest exponents:

$GCF=2^2*5\\\\GCF=4*5\\\\GCF=20$

Therefore, the side lenght of each square must be:

$s=20\ cm$
