According to Geohive.com, the population of China in the year 2016 was estimated to be 1, 382,000,000 people. Write the population in standard scientific notation. b) The diameter of a very fine grain of sand is 6.25 times 10^-8 meters. Write the length in inches in standard decimal notation. c) The per capita debt (debt per person) in 2012 for Massachusetts was $1.45 times 10^4. The population of Massachusetts that year was 6.65 times 10^6 people. What is the total debt? Write the answer in scientific notation.Explanation / Answer
a) The population of China
= 1,382,000,000
The population in standard scientific notation
= 1.382 * 109
b) The diameter of grain of sand
= 6.25 * 10-8 m
The length in decimal notation
= 0.0000000625 m
c) Per capita debt = $1.45 * 104
Population = 6.65 * 106
=> Total debt = Per capita debt * Population
=> Total debt = $1.45 * 104 * 6.65 * 106
=> Total debt = $9.6425 * 1010
