Question 1__________ affects the production of refuse in that the more frequent the collection, the more waste isproduced.Question 2A landfill operation uses a tractor to compact the waste. The tractor weighs 10 tons and has two tracks,each 3 ft by 12 ft. Estimate the maximum compaction attainable in the landfill.Question 3Assume the cost is 50 cents per ton per mile to operate a garbage truck and 15 cents per ton per mile tooperate a transfer truck. A transfer station has a fixed cost of $12/ton. If the landfill is 50 miles from thetransfer station, is the garbage truck or transfer truck cheaper for traveling a 50 mile distance?Question 4In designing a truck route system for waste collection, locations are known as ___________.Question 5A sample of refuse is analyzed and found to contain 10% water (measured as weight loss onevaporation). The heating value (Btu) of the entire mixture is measured in a calorimeter and is found tobe 3000 Btu/lb. A 2.0 gram sample is placed in the calorimeter, and 0.38 grams of ash remains in thesample cup after combustion. What is the moisture- and ash-free heat value?Question 6A __________ is a method that is used to help in the reduction of waste by charging a fee for weighingevery can of waste.Question 7Communities that have converted from the manual system of garbage collection to the fully automatedsystem have saved at least __________ in collection costs.Question 8__________ are based on the concept of minimizing an objective function subject to a constraint. Question 9A local trash hauler charges customers based on the number of 55 gallon trash bags they set out eachweek. A family wants to limit their bill by putting out only one 55 gallon bag per week. If their trash has adensity of about 70 lb/yd3, about how much waste can the family generate each week in order to fill justone bag per week?Question 10Unbeknownst to health regulators, a family is using a shed in their backyard for their solid wastedisposal. The shed is 20 ft long by 15 ft wide by 10 ft high. If the family generates 16 pounds of uncompacted waste per day, at a density of 200 pounds per cubic yard, approximately how long will it taketo fill the shed with their un-compacted waste?Question 11Transfer Stations: In at least 200 words, define the concept of a transfer station and describe how it isused. How is the decision made on whether or not to build a transfer station? Use proper APA formatand citation
