  18. independent practiceExample 5 Solve the formula for the indicated variable.

  19. Checking for understanding… Directions for Partner A - Check to see if your partner understands how to obtain the correct answer. Ask for assistance from your partner or the teacher if you are confused how to achieve the correct answer.

  20. independent practiceExample 6 A forager honeybee spends three weeks becoming accustomed to the immediate surroundings of its hive and spends the rest of its life collecting pollen and nectar. The total number of miles T a forager honeybee flies in its lifetime L (in days) can be modeled by the equation below, where m is the number of miles it flies each day.

  21. independent practiceExample 6 Part A Solve the equation for L.

  22. independent practiceExample 6 Part B A forager honeybee’s flight muscles last only 500 miles; after that he dies. Some forager honeybees fly about 55 miles per day. Approximately how many days do these bees live?

  23. Checking for understanding… Directions for Partner B – Turn to your partner and describe the process you used to obtain the answer. Are your final answers the same?

  24. independent practiceExample 6 Part A Solve the equation for L.

  25. independent practiceExample 6 Part B Approximately 30 days

  26. Practice with your partnerExample 7 Part A Write down the formulas for the area and circumference of a circle.
