## Calculate Mean Cell Residence Time (MCRT) Days

**Mean Cell Residence Time-MCRT (Days) **self-paced WasteWater continuing education course is a learning exercise.

This $20.00 learning experience has Study Material which includes a $50.00 educational video available exclusively only to course enrollees for viewing.

The self-paced WasteWater continuing education course also explains basic wastewater mathematic solution components such as:

**-How to read a math word problem to identify the explicit question **

** ***Learn** **a word problem routine which makes explicit several features of word problems, including the numbers, the question, the equation, a model, and the “answer”.*

**-Learn to select the appropriate formula to solve the exact math problem**

** ***Learn** **that problem solving requires identifying an appropriate formula or procedure and determining what information you will need (and will not be needed) to answer the question.** *

**-Proficiency setting up the equation**

** ***Become proficient** **setting up equations, or writing equations, involves translating a problem from words into a mathematical statement. Determine what the question is asking.*

**-Selecting the “known” information**

** ***Understand** **the first step to effectively translating and solving word problems is to read the problem. Try first to see what information you have, which is “known” information.** *

**-Determining what is “unknown” from the word problem**

*Learn** to figure out what you still need, which is “unknown”. Pick variables to stand for the unknows, clearly labelling these variables with unknowns. And make sure you know just exactly what the problem is asking to be answered.*

**-Familiarity with the equation**

** ***Learn** to solve the problem and as you become more familiar learn to rearrange the equation for more problem solving.*

**-Using units of expression properly while solving the problem**

** ***Learn** **that a conversion factor is a factor used to convert one unit of measurement into another. A simple conversion factor can convert meters into centimeters, or a more complex one can convert miles per hour into meters per second. Since most calculations require measurements to be in certain units, you will find many uses for conversion factors. Always remember that a conversion factor must represent a fact; this fact can either be simple or more complex.*

**-Understand much more!**

** ***Taking this course will help with these achievements and much more**!*** **

*Invest one hour of your time to complete this course and you just might pass the next certification examination!*
