You have 40 sheep, and can get a 2/3 of a bushel of wool from each. You want to buy 1100 bricks from the kiln to enclose a sheepfold to protect your flock. The kiln operator charges a shekel of copper for each 5 bricks. The trader from Anatolia wants as much wool as possible, and will give you 7 shekels of copper for each bushel. So obviously you want to sell your wool to the trader, and then buy the bricks. Write this out as an algebraic problem. Give names for all of the quantities, such as sheep, shekels, etc. But can you buy the 1100 bricks you need? How many bushels of wool extra would you have beyond what you need for the bricks, or how many are you missing? How many sheep does that represent?
An automotive researcher wanted to estimate the difference in distance required to come to a complete stop while traveling 40 miles per hour on wet versus dry pavement. Because car type plays a role, the researcher used eight different cars with the same driver and the same tires. The braking distance (in feet) on both wet and dry pavement is shown in the table. Test to determine whether it takes longer to brake on wet pavement than dry. Car number 1 2 3 4 5 6 7 8 Wet braking distance 106.9 100.9 108.8 111.8 105.0 105.6 110.6 107.9 Dry braking distance 71.8 68.8 74.1 73.4 75.9 75.2 75.7 81.0
You go to the doctor and he gives you 15 milligrams of radioactive dye. After 24 minutes, 5.5 milligrams of dye remain in your system. To leave the doctor's office, you must pass through a radiation detector without sounding the alarm. If the detector will sound the alarm if more than 2 milligrams of the dye are in your system, how long will your visit to the doctor take, assuming you were given the dye as soon as you arrived? Give your answer to the nearest minute. You will spend minutes at the doctor's office.
