Part 1: Using the Library, web resources, and/or other materials, find a record-breaking temperature (in degrees Celsius) for a town or city in a country other than the United States. Include the name of the town and country along with the temperature, and what record was broken. Give the formula for converting degrees Celsius to degrees Fahrenheit. Using the formula, show how to convert the measurement to degrees Fahrenheit.

Part 2: The equation C=mx+b can be used to model the monthly cost, C, of a cell phone plan where b is the flat monthly cost, m represents the cost in dollars per minute and x is the number of minutes used in the month. Choose a flat monthly rate and cost per minute and insert the values you have chosen for m and b into the equation. Then use this equation to find the total monthly cost, C, if 68 minutes are used.

Part 1: Pick your city and temperature and use the formula below.

In the formulas below, / represents division, * represents multiplication, - subtraction, + addition and = is equal.
Tc = (5/9)*(Tf-32); Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit

For example, suppose you have a Fahrenheit temperature of 98.6 degrees and you wanted to convert it into degrees on the Celsius scale. Using the above formula, you would first subtract 32 from the Fahrenheit temperature and get 66.6 as a result. Then you multiply 66.6 by five-ninths and get the converted value of 37 degrees Celsius.

Below is the formula to convert a Celsius scale temperature into degrees on the Fahrenheit scale.

Tf = (9/5)*Tc+32; Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit

Part 2: Just insert the values for m and b that you want and then solve for C when x = 68.

You can do the calculations.

Part 2: The equation C=mx+b can be used to model the monthly cost, C, of a cell phone plan where b is the flat monthly cost, m represents the cost in dollars per minute and x is the number of minutes used in the month. Choose a flat monthly rate and cost per minute and insert the values you have chosen for m and b into the equation. Then use this equation to find the total monthly cost, C, if 67 minutes are used (or as if there were 67 minutes of overage).

Part 1:

To find a record-breaking temperature in a town or city outside the United States, you can use various resources like library books, online weather archives, or climate databases. One reliable source of information is the World Meteorological Organization (WMO) which maintains climate records globally.

Let's assume we want to find the record-breaking temperature in the town of Cloncurry, Australia. According to the WMO, Cloncurry holds the highest temperature recorded in Australia.

The record temperature in Cloncurry, Australia is 53.1 degrees Celsius (127.6 degrees Fahrenheit). This record was set on January 16, 1889.

To convert degrees Celsius to degrees Fahrenheit, you can use the following formula:

°F = (°C × 9/5) + 32

Let's calculate the equivalent temperature in degrees Fahrenheit for the record-breaking temperature in Cloncurry:

°F = (53.1 × 9/5) + 32
°F = (95.58) + 32
°F ≈ 127.6

Therefore, the record-breaking temperature in Cloncurry, Australia, was 53.1 degrees Celsius (127.6 degrees Fahrenheit).

Part 2:

In order to find the total monthly cost, C, using the equation C = mx + b, we need to choose values for the flat monthly cost, b, and the cost per minute, m.

Let's assume the flat monthly cost is $30 and the cost per minute is $0.50. We can substitute these values into the equation as follows:

C = (0.50 * 68) + 30
C = 34 + 30
C = $64

Therefore, if 68 minutes are used, the total monthly cost of the cell phone plan would be $64.
