Answer: 33 gallons
Step-by-step explanation:
We initially have 130 gallons of a acid solution and we need to change it to a acid solution, and for that it is necessary to evaporate gallons of water.
So, this situation can be mathemtically expressed as follows:
Then:
Isolating :
Hence, we need to evaporate 33 gallons of water.
Answer:
20,158 cases
Step-by-step explanation:
Let represent year 2010.
We have been given that since 2010, when 102390 Cases were reported, each year the number of new flu cases decrease to 85% of the prior year.
Since the flu cases decrease to 85% of the prior year, so the flu cases for every next year will be 85% of last year and decay rate is 15%.
We can represent this information in an exponential decay function as:
To find number of cases in 2020, we will substitute in our decay function as:
Therefore, 20,158 cases will be reported in 2020.
