In 2011, an earthquake with magnitude 9.0 on the Richter scale was recorded off the east coast of Japan. Hundreds of aftershocks came in the days that followed, some with the magnitudes as great as 7.4 on the Richter scale. In order to compare the relative intensities, I, of these two earthquakes, the following formula may be used: 10m 10" where m andn are the Richter scale values of each earthquake. Compared to the aftershocks, the earthquake off the east coast of Japan, to the nearest whole number, was times stronger.
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.
