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 …
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 experime…

Chapter 7.2, Problem 129E

The way that we perceive the temperature on a cold day depends on both air temperature and wind speed. The windchill is what the air temperature would have to be with no wind to achieve the same chilling effect on the skin. In 2002, the National Weather Service issued new windchill temperatures, shown in the table below. (One reason for this new windchill index is that the wind speed is now calculated at 5 feet, the average height of the human body’s face, rather than 33 feet, the height of the standard anemometer, an instrument that calculates wind speed.)

Chapter 7.2, Problem 129E, The way that we perceive the temperature on a cold day depends on both air temperature and wind

The windchill temperatures shown in the table can be calculated using

C = 35.74 + 0.6215 t − 35.74 v 4 25 + 0.4275 t v 4 25 ,

in which C is the windchill, in degrees Fahrenheit, t is the air temperature, in degrees Fahrenheit, and U is the wind speed, in miles per hour. Use the formula to solve Exercises 129–132.

a. Rewrite the equation for calculating windchill temperatures using rational exponents.

b. Use the form of the equation in part (a) and a calculator to find the windchill temperature, to the nearest degree, when the air temperature is 25°F and the wind speed is 30 miles per hour.
