Answer:
5 months
Step-by-step explanation:
120 * 10m = 150 * 4m
subtract 4m to 10m
120 * 6m = 150
subtract 120 to 150
6m = 30
divide 6 to 30
30 / 6 = 5
5 months
Lets pretend the humidity is 100, we would do
100 - 100 * .0225
and do it 7 more times with the new numbers.
The final answer would be 83.35 humidity. The total change is then 16.65%
To factor completely 18b - 32, we factor out the common factor of the two terms and divide each of term by the common factor.
18b - 32 = 2(18b/2 - 32/2) = 2(9b - 16)
The answer is 4,851,000because you would need to multiply all numbers
