1. How many gallons of bolognaise sauce can be made using 4.75 pounds of ground chuck if the original recipe yields 1 gallon and calls for 2.5 pounds of ground chuck? 2. A restaurant with an on-site garden uses leftover coffee grounds as a medium for growing mushrooms. If 5 1/2 pounds of coffee grounds grow enough mushroom spores to yield 3 pounds of mushrooms, how many pounds of coffee grounds are needed to yield 20 pounds of mushrooms? ( show as a mixed number.)

3. A chili recipe calls for 12 ounces of finely diced onions and normally yields 2 gallons. If the recipe is scaled to make 2 quarts, how many ounces finely diced onions are required?

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
