Perth Mining Company operates two mines to extract gold and silver. The Saddle Mine yields 50 oz of gold and 2000 oz of silver each day. The Horseshoe Mine yields 75 oz of gold and 1000 oz of silver each day. The Company set a target at least 600 oz of gold and 20,000 oz of silver. The cost to operate the Saddle Mine costs $14,000 per day and the Horseshoe Mine cost $16,000 per day. How many days should each mine operate to meet the Company's target at a minimum cost? a. write the objective function. Identify variables.  b. write the system of inequalities describing the above constraints.  c. create a chart to identify the number to minimize cost, label each. also lost the minimum cost.

A toy factory creates miniature steel train engines and box cars. The fabrication department has 3,679 minutes available per week and the assembly and finishing department has 3,099 minutes available per week. Manufacturing one miniature steel train engine requires 8 minutes of fabrication and 5 minutes of assembling and finishing. Manufacturing one miniature steel box car requires 4 minutes of fabrication and 5 minutes of assembling and finishing. The profit on each miniature steel train engine is $8.00 and the profit on each miniature steel box car is $7.25. How many steel train engines and steel box cars should be produced each week to obtain the maximum profit? Find the maximum weekly profit. (Use x for box car and y for train engine.)

Find the volume of a solid generated by revolving, about the y-axis, the region bounded by v = 2e* , y = 0, x = 0, and x = 1. O The volume is 2 (ne – 1) cubic units. The volume is 2 (re – 1 ) cubic units. - The volume is 2re - T cubic units. The volume is 4 (ne – n ) cubic units.

An investor has $5000 to invest in three different accounts. One is low-risk,one is a medium-risk and the third is a high-risk investment. The low-risk account is expected to pay 5.2% interest, the medium-risk investment is expected to pay 6.7% interest and the high-risk investment is espected to pay10.3% interest. Due to her age, the investor is willing to invest twice as much money in the high-risk account as in the low-risk investment. How much money should be invested in each of the accounts to anticipate a return of 8% on the total investment.
