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.
A general contractor is needing to put together a price to build this concrete parking lot.
(first picture)
Using the dimensions given, find the volume of concrete for the parking lot. Concrete is poured to a depth of 6 inches in parking lots.
Diagram marked for measuring:
(second picture)
NOTE: At the bottom of this diagram, you can see there are two sectors, and one rectangle. Remember to add the volume of this area to the volume of the larger rectangular parking lot that it’s connected to.
Using the diagram marked for measuring,
a = 126 feet, b = 18 feet, c = 28.6 feet and d = 92.5 feet. Remember the depth of the concrete will be 6 inches (or .5 feet). Find the total volume of concrete in this parking lot. Use 3.14 for pi and round your final answer to nearest tenth.
