On April 7, 2011, an earthquake of magnitude 6.5 on the Richter scale struck Veracruz, Mexico. On August 23, 2011, an earthquake of magnitude 5.8 on the Richter scale shook the East Coast of the United States. (Round your answers to two decimal places.) (a) How did the power of the East Coast and Veracruz quakes compare? The Veracruz quake was times as powerful as the East Coast quake. (b) What would be the magnitude of a quake three times as powerful as the Veracruz quake?
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.
