# Salt mixing problem algebra

The main issue with these problems is to correctly define conventions and then remember to keep those conventions. The water is removed from the original. Percent Mixture Problem 3 How to solve percent mixture problem using one variable? We will need to examine both situations and set up an IVP for each. Six years ago, he was five times as old as his son was at that time. What is the percent concentration of pure apple juice in the resulting mixture?

## Draining tank differential equation

Note that at this time the velocity would be zero. The age of the son is: Solution a. How old is her daughter now? The table shows the relationship between their past and present ages. So, the IVP for each of these situations are. In other words, eventually all the insects must die. Problem 4: Father and Son's Ages A father is four times as old as his son. Notice the conventions that we set up for this problem. In this case, the differential equation for both of the situations is identical. We could have just as easily converted the original IVP to weeks as the time frame, in which case there would have been a net change of —56 per week instead of the —8 per day that we are currently using in the original differential equation. Let x be the age of John now. How many years will the father be three times as old as his son?

Okay back to the differential equation that ignores all the outside factors. We recommend using a table to organize your information for mixture problems.

## Mixing problems differential equations overflow

The main issue with these problems is to correctly define conventions and then remember to keep those conventions. Peter is twice as old as John was when Peter was as old as John is now. We recommend using a table to organize your information for mixture problems. Try the given examples, or type in your own problem and check your answer with the step-by-step explanations. We could very easily change this problem so that it required two different differential equations. Notice the conventions that we set up for this problem. Let x be the present age of John. Problem 3: Mother and Daughter's Ages A mother is 41 years old, and in seven years she will be four times as old as her daughter. Show Solution So, this is basically the same situation as in the previous example. Applying the initial condition gives the following. For population problems all the ways for a population to enter the region are included in the entering rate. In other words, eventually all the insects must die.
