A farmer wants to enclose a rectangle shaped field the size of 6000 ft^2 on his farm adjacent to a river. His plan is to divide the field into 4 sections. He does not need a fence along the river. His neighbor will pay half the price of the fence bordering the 2 properties. The farmer wants a strong fence on the south side that costs $10 a foot, and a cheap fence for the rest that cost $8 a foot. Find the dimensions of the field that minimize the cost of building the fence. Picture of the fence is below.
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.
