The Nueva Ecija Feeds Inc. Produces specially blended feed supplements. It has an order of no more than 400 pounds of the mixture. This consists of two ingredients: P, a source of Protein and C, a carbohydrate source. The first ingredient P, costs P6 a pound. The second ingredient C, costs P16 a pound. The mixture cannot be more than 150 pounds P, and it must have at least 200 pounds C. The company’s problem is to determine how much of each ingredient to use to minimize cost, but satisfy the requirements.
Here is a copy of the previous problem: A university math department offers courses in College Algebra, Finite Mathematics, and Applied Calculus. Each section of College Algebra is worth 3 credits and has a capacity of 35 students.Each section of Finite Math is worth 4 credits and has a capacity of 30 students.Each section of Applied Calculus is worth 4 credits and has a capacity of 25 students. Last semester, the department offered a total of 96 credits and all the classes were filled to capacity. Seven hundred ninety students were enrolled, and no student took more than one of the three courses. The department offered half as many sections of Applied Calculus as Finite Math. Set up a system of equations for this problem wherec represents the number of sections of College Algebra offered,f represents the number of sections of Finite Math offered, anda represents the number of sections of Applied Calculus offered. You do not need to solve the system.The other equation of the system…
This is not the correct solution. Is there another solution avaliable for this problem?
I don't know how to accurately answer this question. I have followed the steps and have gotten 3 different answers each time. I am not sure which step I am missing or messing up on. I don't know if I am using the wrong formula but I would appreciate as much help as possible by guiding me through each step. Thank you so much.
Can you please help me with these two questions?
The town councils of Cambridge, Bridgwater and Bath each placed an order with a tree nursery. Cambridge ordered 4 lime trees, 20 plane trees and 12 rowan trees, and the total cost was £1296. Bridgwater ordered 10 lime trees, 6 plane trees and 32 rowan trees, and the total cost was £1746. Bath ordered 8 lime trees, 14 plane trees and 16 rowan trees, and the total cost was £1498.By modelling the problem as a system of three linear simultaneousequations, use matrices to find the cost per tree of each type of tree.

While working on the multiplication problem 38 x 25, Maria says this: “Four times 25 is 100, so 40 times 25 is 1000. Now take away 2, so the answer is 998.” Is Maria’s method correct or not? If it is correct, write equations that incorporate Maria’s work and that show why it’s correct. If Maria’s reasoning is not correct, explain why. Work with portions that are right to correct Maria’s work, and write a string of equations that corresponds to your corrected method for calculating 38 x 25. In either case, write your equations in the following form:
A tutoring service provides tutoring for a fee. When the tutoring service charges $11/hour, there is a demand for 28 tutors per week. When the hourly rate rises to $17/hour, the demand drops to 16 tutors per week. On the other hand, at $11/hour, the service is able to support only 28 tutors per week, whereas at the rate of $17/hour, it is able to provide 58 tutors per week. Find the price per hour at which the number of tutors demanded and the number of tutors supplied will be equal.
So I decide to go to Cinnaholic once day and I buy two cinnamon rolls. I notice that these cinnamon rolls do not appear to be the same size, so naturally I eat the smaller one first and then eat the bigger one. As I am sitting on my couch stuffed from those delicious rolls, I start to think, "I wonder if Cinnaholic makes their cinnamon rolls to the size they claim them to be." Of course I have to go and purchase several rolls, weigh them (in ounces), and eat them. 30 pounds later, I have collected all of my data and tabulated it below: Cinnamon Roll Weight 5.6, 6.3, 6.1, 6.1, 5.9, 5.8, 6.0, 6.0, 6.1, 6.3, 6.3, 6.3, 6.4, 5.8, 5.7. Cinnaholic claims that their Cinnabon rolls are made to weigh 6.1 ounces on average. The mean is 6.0467 Standard deviation: 0.2475
