**Problem Statement:**Three species of bacteria are fed three foods, I, II, and III. A bacterium of the first species consumes 1.2 units each of food I and II, and 2.5 units of food III each day. A bacterium of the second species consumes 1.1 units of food I, 2.3 units of food II, and 3.6 units of food III each day. A bacterium of the third species consumes 8.4 units of I, 2.7 units of II, and 5.3 units of III each day. If 16,500 units of food I, 27,000 units of food II, and 45,000 units of food III are supplied each day, how many of each species can be maintained in this environment?---**Solution Format:**There should be about [BOX] bacteria of the first species, about [BOX] bacteria of the second species, and about [BOX] bacteria of the third species. (Round to the nearest integer as needed.)

A group of scientists studied the effect of a chemical on various strains of bacteria. Bacteria A started with 12000 cells and decreased at a constant rate of 3000 cells per hour after the chemical was applied. Strain B started with 4000 cells and decreased at a constant rate of 2000 cells per hour after the chemical was applied. When will the strains have the same number of cells?

A mining company owns two mines. These mines produce an ore that can be graded into two classes: regular grade and low grade. The company must produce at least 410 tons of regular-grade and 530 tons of low-grade ore per week. The first mine produces 6 tons of regular-grade and 16 tons of low-grade ore per hour. The second mine produces 20 tons of regular-grade and 10 tons of low-grade ore per hour. The operating cost of the first mine is $9000 per hour, and the operating cost of the second mine is $30,500 per hour. The first mine can be operated no more than 55 hours a week, and the second mine can be operated no more than 29 hours a week. How many hours per week should each mine be operated to minimize the cost? First Mine: __ hours Second Mine:__ hours
Consider the following approach: At an animal shelter, three types of food are provided for three species of freshwater turtles. Each turtle of species 1 consumes an average of 1 unit of food A, 1 of B and 2 of C per week. Species 2 consumes 1 unit of food A, 4 of B and 5 of C. Species 3 requires 2 units of food A 1 of B and 5 of C. It is known that the shelter can supply weekly 99 units of food A, 181 units B and 320 units of C. If we assume that the turtles consume all the food, indicate the number of turtles of each species that the shelter can maintain. a. Establishes the system of linear equations that models the approach b. Solve the system of linear equations using the Gauss-Jordan method

Internet Audience At the end of a certain year, the four companies with the largest number of home Internet users in the United States were Microsoft, Time Warner, Yahoo, and Google, with a combined audience of 284 million users. Taking x to be the Microsoft audience in millions, y the Time Warner audience in millions, z the Yahoo audience in millions, and u the Google audience in millions, it was observed that zu = x + y = and xy + zu = 44. How large was the audience of each of the four companies at the end of that year? Microsoft Time Warner Yahoo Google 3(x - y) + 8 50 + z + u
A nutritionist is performing an experiment on student volunteers. She wants to feed one of the volunteers a daily diet that consists of a combination of three commercial diet foods: MiniCal, LiquiFast, SlimQuick. For the experiment, it is important that the volunteer consume a total of exactly 500 of potassium, 75g of protein, and 1150 IU of vitamin D every day. The amounts of these nutrients in one ounce of eacl diet food are given in the table. How many ounces of each food should the volunteer eat every day to satisfy the nutrient requirements exactly? MiniCal (1 ounce) LiquiFast (1 ounce) SlimQuick (1 ounce) Potassium (mg) 50 75 10 Protein (g) 10 3 vitamin D (IU) 90 100 50 Solve the system algebraically or use the rref in your graphing calculator to find the amount of ounces of each food needed to satisfy the nutrient requirements.
A freshly brewed shot of espresso has three distinct components: the heart, body, and crema. The separation of these three components typically lasts only 10 to 20 seconds. To use the espresso shot in making a latte, a cappuccino, or another drink, the shot must be poured into the beverage during the separation of the heart, body, and crema. If the shot is used after the separation occurs, the drink becomes excessively bitter and acidic, ruining the final drink. Thus, a longer separation time allows the drink-maker more time to pour the shot and ensure that the beverage will meet expectations. An employee at a coffee shop hypothesized that the harder the espresso grounds were tamped down into the portafilter before brewing, the longer the separation time would be. An experiment using 24 observations was conducted to test this relationship. The independent variable Tamp measures the distance, in inches, between the espresso grounds and the top of the portafilter (i.e., the harder the…
A dietitian in a hospital is to arrange a special diet composed of three basic foods. The diet is to include exactly 340 units of calcium, 180 units of iron, and 400 units of vitamin A The number of units per ounce of each special ingredient for each of the foods is indicated in the table. Construct a Units per Ounce Food A Food B Food C Calcium 30 10 20 Iron 10 10 20 Vitamin A mathematical model to complete parts (A) through (C) below. Use Gauss-Jordan elimination to solve the model and then interpret the solution. 30 30 Construct a mathematical model for this situation. Let the first, second, and third equations represent calcium, iron, and vitamin A, respectively.
