Math Tools: Chapters 9-12

Chapter 9- Directional Measurements:

Journalists sometimes have too look at or calculate things like time, rate and distance.Directional measurements like this can be very important in a story to clarify facts to readers. If these numbers can be checked and secured with officials, it will make the reported more accurate and give them more credibility. Miles per hour, speech, acceleration, distance, velocity and momentum are some of the things a reporter can calculate to help their article.

Chapter 10- Area Measurements:

There are two ways to explain and examine area. One way is by analogy. Comparing a space to something of equal size that the average person will understand like a football field. This can give readers a great visual sense of an area and its size. But it is not good when exact measurements are important to the story. The second way is by simple, exact measurements. This includes calculating things like perimeter, square feet and area.

Chapter 11- Volume Measurements:

Like area, volume can play an important role in understanding the size of something. In business reporting, volume can help when looking at things like boxes, barrels, tons, etc. Many goods are also based on volume and are sold in quantities based on it. Some things that are looked at in terms of volumes are liquid measurements, rectangular solids, cords (how firewood is measured), and tons.

Chapter 12- The Metric System:

Even though many Americans are not fully familiar with the entire metric system, it is very important when looking at international businesses and measurements. The meter is the basic unit of measurement in this system. Mass is also derived from the meter. The metric unit force is the Newton.One kilogram weighs 9.8 Newtons on Earth (gravity).

The important units to know are mass is measured in grams, length is measured in meters and volume is measures in liters.
