Engr. Janry Garcia and Engr. Caroline Moncada is working on a project for a newly constructed 4-story building. The project is regarding CCTV installation. As project engineers, they need to assess and make an inventory of the primary materials to be installed in the building. The following primary materials give the merchandise with its corresponding price list. C=CCTV Camera worth P5000 each; W=Cable wires P100 per meter; S=Splitters worth P50 each and B=Balun and Connectors for P150. Each of the materials should be distributed depending on the number of units per floor. For the 1st floor: twice the number of CCTV cameras is needed, three times the length of cable wire is required, four times the number of splitters and five times the number of baluns and connectors less is necessary, which gives an acceptable loss of -60dB. For the 2nd floor: 6 times the number of CCTV cameras are required, seven times the length of cable wire is needed, eight times the number of splitters less and nine times the number of baluns and connectors is necessary resulting in a good gain of 96dB. For the 3rd floor: 10 times the number of CCTV cameras are needed, 11 times the length of cable wire is necessary, 12 times the number of splitters, and 13 times the number of baluns and connectors is required resulting in a good gain of 3120 dB. On the last floor: 14 times the number of CCTV cameras are needed, 15 times the length of cable wire is necessary, 16 times the number of splitters and 17 times the number of baluns and connectors less is required resulting in a good gain of 4160dB. Formulate the equations for each floor and solve the number of materials needed for the whole project using Gauss-Jordan Elimination. How much is the total cost of the project?
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
