Each word problem on this page are to be done one each night. It is allowed to work ahead of schedule, but some of the topics covered by the homework will be taught throughout the week, so do not feel defeated if you are unable to solve the problem correctly before the skill is taught. Just attempt the problem again after the concept is covered in class and you have your notes to help you. Remember PERSEVERANCE is the key this year! Remember to answer each question COMPLETELY! You can model your work through pictures, numbers, number line, etc.) Then you must write words to explain your answer. I want to see your thought process and know how you got to your answer. (Use a separate sheet and staple it to this page so you have more room to work!!!)Jana is doing an experiment. She is on a dock that is 10 feet above the surface of the water. Jana drops the weighted end of a fishing line 35 feet below the surface of the water. She reels out the line 29 feet, and then reels it back in 7 feet. What is the final distance between Jana and the end of the fishing line?Kirsten and Gigi are riding in hot air balloons. They start 500 feet above the ground. Kirsten’s balloon rises 225 feet, falls 105 feet, and then rises 445 feet. Every time Kirsten’s balloon travels up or down, Gigi’s balloon travels 15 feet farther in the same direction. Then both balloons stop moving so a photographer on the ground can take a picture. Find Kirsten’s final position relative to the ground.Is Kirsten or Gigi closer to the ground when the photographer takes the picture?Explain your answer by modeling or drawing a picture and then writing a summary of how you got your answer.You have $220 in your savings account. You take $35 from your account each week for four weeks. How much is left in your account at the end of the four weeks? How did you get your answer?The surface temperature of a deep, spring-fed lake is 70°F. The lake temperature drops 2°F for each yard below the lake surface until a depth of 6 yards is reached. From 6 yards to 15 yards deep, the temperature is constant. From 15 yards down to the spring source, the temperature increases 3°F per foot until the spring source is reached at 20 yards below the surface. What is the temperature at 10 yards below the surface? What is the temperature at 50 feet below the surface? Write an expression for finding the lake temperature at the spring source. ................
