Manufacturing The Digital Star Company makes two different models of computer tablets, which are assembled on two different assembly lines. Line 1 can assemble 30 units of the Star model and 40 units of the Prostar model per hour, and Line 2 can assemble 150 units of the Star model and 40 units of the Prostar model per hour. The company needs to produce at least 270 units of the Star model and 200 units of the Prostar model to fill an order.
(a) Write the inequalities that describe the production constraints on the number of each type of tablet needed to fill the order.
(b) Graph the region determined by these constraint inequalities.

- Suppose the coal and steel industries form a closed economy. Every $1 produced by the coal industry requires $0.30 of coal and $0.70 of steel. Every $1 produced by steel requires $0.80 of coal and $0.20 of steel. Find the annual production (output) of coal and steel if the total annual production is $20 million.arrow_forwardEvertight, a leading manufacturer of quality nails, produces 1-, 2-, 3-, 4-, and 5-inch nails for various uses. In the production process, if there is an over- run or the nails are slightly defective, they are placed in a common bin. Yesterday, 651 of the 1-inch nails, 243 of the 2-inch nails, 41 of the 3-inch nails, 451 of the 4-inch nails, and 333 of the 5-inch nails were placed in the bin. (a) What is the probability of reaching into the bin and getting a 4-inch nail? (b) What is the probability of getting a 5-inch nail? (d) If an application requires a nail that is 3 inches or 4 inches, what is the probability of getting a nail from the common bin that will satisfy this requirement?

The artists plan to produce ink drawings and watercolors. They have volunteered to spend 120 hours of preparation time, and 60 hours of packaging time. It takes 0.3 hours to prepare each ink drawing, and 0.5 hours to prepare each watercolor. It takes 0.2 hours to package each of the cards. Let a represent the number of ink drawings. Let y represent the number of watercolors. Which set of inequalities represents this situation?arrow_forwardRVW (Restored Volkswagens) buys 15 used VW's at each of two car auctions each week held at different locations. It then transports the cars to repair shops it contracts with. When they are restored to RVW's specifications, RVW sells 10 each to three different used car lots. There are various costs associated with the average purchase and transportation prices from each auction to each repair shop. Also there are transportation costs from the repair shops to the used car lots. RVW is concerned with minimizing its total cost given the costs in the table below. a.
