A computer aided drafting (CAD) instructor at a community college wants to use his rapid prototype machine to produce demo items for a seminar on engineering technology. He plans to bring two different types, a Golden Ruler and a Fibonacci Gauge. He will bring at least 20 of each. he has 45 cubic inches of filler and 95 cubic inches of material available to make the demos, but only has 86 hours of free time to run the machine. he is able to save time by running the demos in batches. Use the information in the table to determine how many of each demo item he needs to bring while minimizing the total cost. Set up but do not solve.

Demo Type	Material (in³/batch)	Filler (in³/batch)	Batch Time (hrs)	Batch size	Batch cost ($)
Golden Ruler	10	3	7	8	22
Fibonacci Gauge	7.5	5	8.5	10	20

Expert Solution

Answer: det a number of Golden Ruler batches, Y = number of fibonacci hauges, our job is to minimize total cost, 2= 22x+2y Under the constraints 10x +7.54 <45 (Material) 3x + 5y {as (filler) 7x+8.54 286 hours) x>, and y=2 (He needs at least 3 batches to produce a mininum of 20 Golden Ruless, at least 2 batches of fibonacci Ganges, also to meet the minimum of 20). 402 + 754 $ 45 84 1120, 26,667) 3 x + 2 y = 95 hot + Body = 86 A 124,0) -30 -20 o 10 20 30 yo tot

An instructor in a college biology course wants to test a new method for learning Punnett squares. He begins by pairing students with similar entrance exam scores (ACT scores). Then he randomly selects one student from each pair to receive a new curriculum on Punnett squares, while the other student receives the traditional curriculum. At the end of the semester, he administers a genetics quiz with multiple Punnett square problems and records the number of errors. There are 24 students...

[Parker County Community College (PCCC) is trying to determine whether to use no insulation or to use insulation that is either 1 inch thick or 2 inches thick on its steam pipes. The heat loss from the pipes without insulation is expected to cost $1.50 per year per foot of pipe. A 1-inch thick insulated covering will eliminate 89 percent of the loss and will cost $0.40 per foot.A 2-inch thick insulated covering will eliminate 92 percent of the loss...
