The population of the united states is 3 × 10^8 people, and the population of the world is 6.9 × 10^9 people. how many times larger is the world population? write your answer in standard notation.

put the united states population over the world population you will get a simplified fraction to the ratio between them which is 1/23   easily you can multiply 23 by the USA population to get the world population so it is more than USA population 23 times  

3*10^8 / 6.9*10^9 = 1/23

then   23  *  3*10^8  = 6.9*10^9  

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
