Question
3) Koby is mixing birdseed. He wants 2/5 of the mixture to be millet and 3/5 of the mixture to be sunflower seeds. If he has 24 pounds of millet, how many pounds of sunflower seeds does he need? 4) The ratio of commuter trains to all trains through the station is 10 to 13. On a given day, there are 21 non-commuter trains. How many commuter trains are there? 5) Becky is cutting wood. She is cutting a long board into two pieces with lengths in ratio 9 to 5. The longer piece is 54 inches. How long is the original board? 6) Becky is cutting another board that starts out at 88 inches. The ratio of the two pieces she gets is 5 to 6. How long is each piece? 7) The ratio of sodium to potassium in orange-peach-mango juice is 10 to 350. If there are 525 mg of potassium in the glass of juice, how much sodium is there? 8) Using the same ratio in problem 7, consider a glass of juice with a combined sodium plus potassium content of 900 mg. How much potassium does the glass contain? Directions: Answer the following questions by writing out one calculation including all relevant units words as in the baby example (which can be found in the big packet at the end of the demo in lesson #4). These are all calculator-active problems. 9) What is the length in feet of a sofa that measures 84 inches? 10) How many seconds are in one week? 11) How many feet are in 18 yards? 12) How many square meters are there in 15,400 square centimeters? (Note: 1 meter = 100 centimeters) Directions: Use dimensional analysis (including all units throughout your computation) to answer the following questions. 13) You work 40 hours per week and are paid $13.50 per hour. If you work all 52 weeks in a year, how much will you earn? 14) Water is flowing through a pipe at a rate of 15 cubic feet per hour. How fast is it flowing in cubic inches per minute? (Hint: Try writing cubic feet as feet x feet x feet) 15) A patient in the Emergency Center is diagnosed with atrial fibrillation with a rapid ventricular response. The doctor orders 0.25 milligrams of digoxin I.V. The vial reads "0.5 mg/mL". How many milliliters will you give the patient? 5
