Chapter 1: Problem 62

Celsius and Fahrenheit Temperatures In the met- ric system of weights and measures, temperature is measured in degrees Celsius (" \(^{\circ}\) C) instead of degrees Fahrenheit \(\left(^{\circ} \mathrm{F}\right) .\) To convert between the two systems, we use the equations $$ C=\frac{5}{9}(F-32) \quad \text { and } \quad F=\frac{9}{5} C+32 $$ In each exercise, convert to the other system. Round answers to the nearest tenth of a degree if necessary. $$200^{\circ} \mathrm{C}$$

Celsius to Fahrenheit Conversion
Converting temperatures from Celsius to Fahrenheit is a common task in science and everyday life. The formula to switch from Celsius to Fahrenheit is straightforward: \( F = \frac{9}{5} C + 32 \).
This means you take your Celsius temperature, multiply it by 9/5, and then add 32 to convert it to Fahrenheit.

Let's break it down with an example:
Suppose you have a temperature of 200掳C and you need to find out how much that is in Fahrenheit:
\( F = \frac{9}{5} \times 200 + 32 \)
First, multiply 200 by 9/5, which equals 360.
Next, add 32 to 360.
So, \( F = 360 + 32 = 392 \).
Hence, 200掳C is equal to 392掳F. Remember to always follow the order of operations: first the multiplication, then the addition.
Fahrenheit to Celsius Conversion
Converting from Fahrenheit to Celsius is like flipping the previous formula. The conversion formula here is \( C = \frac{5}{9}(F - 32) \).
It starts with subtracting 32 from the Fahrenheit temperature and then multiplying by 5/9.

Let's use an example to clarify:
Suppose you have a temperature of 392掳F and need to find out how much it is in Celsius:
\( C = \frac{5}{9}(392 - 32) \)
First, subtract 32 from 392, which equals 360.
Then, multiply 360 by 5/9.
So, \( C = \frac{5}{9} \times 360 = 200 \).
Therefore, 392掳F is equal to 200掳C. Conversion in this manner requires careful attention to the order: subtraction first, then multiplication.
Metric System
The Metric System is a decimal-based system of measurement used around the world, particularly in scientific contexts. It includes units like meters for distance, grams for weight, and degrees Celsius for temperature.

Advantages of the metric system include:
  • Simplicity: Conversions within the metric system are seamless because they are all base-10.
  • Universality: It's used globally, making scientific communication clearer.
  • Consistency: Units are standardized, reducing confusion in measurements.

For temperature, the Celsius scale is used in the metric system. Water freezes at 0掳C and boils at 100掳C.
In contrast, the Fahrenheit scale, which is part of the Imperial system, has water freezing at 32掳F and boiling at 212掳F.
Understanding how to convert between Celsius and Fahrenheit thus becomes essential for working across different measurement systems.

When humans breathe, carbon dioxide is emitted. In one study, the emission rates of carbon dioxide by college students were measured during both lectures and exams. The average individual rate \(R_{L}\) (in grams per hour) during a lecture class satisfied the inequality $$\left|R_{L}-26.75\right| \leq 1.42,$$ whereas during an exam the rate \(R_{E}\) satisfied the inequality $$\left|R_{E}-38.75\right| \leq 2.17.$$ Use this information in Exercises. The class had 225 students. If \(T_{L}\) and \(T_{E}\) represent the total amounts of carbon dioxide in grams emitted during a one-hour lecture and exam, respectively, write inequalities that model the ranges for \(T_{L}\) and \(T_{E}\).

Solve each equation or inequality. $$|3 x+2| \leq 0$$

Complex numbers are used to describe current I, voltage \(E,\) and impedance \(Z\) (the opposition to current). These three quantities are related by the equation \(E=I Z, \quad\) which is known as Ohm's Law. Thus, if any two of these quantities are known, the third can be found. In each exercise, solve the equation \(E=I Z\) for the remaining value. $$I=10+4 i, E=88+128 i$$

A charter bus company charges a fare of \(\$ 40\) per person, plus \(\$ 2\) per person for each unsold seat on the bus. If the bus holds 100 passengers and \(x\) represents the number of unsold seats, how many passengers must ride the bus to produce revenue of \(\$ 5950 ?\) ( Note: Because of the company's commitment to efficient fuel use, the charter will not run unless filled to at least half-capacity.)
