0.505 means 505 * 0.001, or 505 * 1/1000. This is equivalent to 505/1000, or 101/200.
The answer to this question is 3/8
Answer:
Average rate of change = 0.29 million per year
Step-by-step explanation:
Average rate of change in the population from year 1970 to year 1900 is given by the formula,
Average rate of change = 
= 
= 
= 0.29 million per year
Therefore, average rate of change in the population from 1970 to 1990 will be 0.29 million per year.
Answer:
Below.
Step-by-step explanation:
a. 5 * 1000 = 5,000 micrometers
b. 5000 / 1000 = 5 kg
c. 4.23 * 10^12 = 4,230,000,000,000 picograms
d. 1.9 ^ 10^9 = 1,900.000,000 nanoseconds.
e. 2.3 million.
The inequality is 4 ≥ x/2.1, and the answer is 8.4 ≥ x (or x ≤ 8.4).
To solve this, we multiply both sides by 2.1:
4*2.1 ≥ x
8.4 ≥ x.
