Answer:
Class A :
Class B :
Step-by-step explanation:
Class A :
Let the amount of Salt in the solution be represented by y as, it is supposed to be the independent variable.
Similarly let the amount of Water in the solution be x
As we are given that for Class A , The ratio of salt content to water content is 3 to 5
Hence
Multiplying both sides by x we get
Class B :
Let the amount of Salt in the solution be represented by y as, it is supposed to be the independent variable.
Similarly let the amount of Water in the solution be x
As we are given that for Class A , The ratio of salt content to water content is 2 to 4
Hence
multiplying both sides by x we get
Original Population = 1236000
Growth Rate = 1.3% per year
Since the population grows at an exponential rate, we can say that the growth of the population is an exponential growth.
Using the formula of exponential growth
population after 10 years = Original population (1-1.3%)^10
= 1236000 {1+(1.3/100)}^10
= 1236000 (1+0.013)^10
= 1236000 × 1.013^10
= 1236000 × 1.13787
= 1406407.32
