1. Onion rings are made from slices of onions, coated with batter and deep fried until golden-brown. One batter recipe calls for  eggs. If x = 2, how many eggs are needed for this recipe?
2. The number of calories per serving of a certain brand of onion rings is the solution to the equation:
8(x - 31) = 7(x + 56).
What are the number of calories per serving? |
3. Onion rings vary in size. The five rings in the graphic at the top of the page have diameters of 3 inches, 3.2 inches, 2.8 inches, 3.5 inches and 2.9 inches. If it were possible to straighten out the rings, and lay them end to end, how long would this line of onion rings be, to the nearest tenth of an inch?
4. The amount of time, in minutes, it takes to deep fry five onion rings is the solution to the equation: 3x + 8 = 8x - 7.
How long, in minutes, does it take to deep fry five onion rings?
| 5. A two dimensional picture of a circular onion ring is shown at the right. The inner radius of the onion ring is x cm. and the thickness of the ring is 1 cm. Which of the numbered choices represents the area, in square centimeters, of the onion ring (the shaded region)? |
