The mathematical relationship between temperature readings on Centigrade and Fah

Question

The mathematical relationship between temperature readings on Centigrade and Fahrenheit thermometers is expressed by the equation below. What is the equation to determine the Fahrenheit temperature given a Centigrade measurement? degree C = 5/9 (degree F-32) Calculate the Centigrade result when the Fahrenheit temperature is 75 degree F. If a car uses 10 gallons of gasoline in traveling 160 miles, how many gallons will be required in traveling 500 miles? One liter = 1.056 quarts and 4 quarts = 1 gallon. How many gallons of water are represented by 500 liters of water. A radio was bought for $200.00 and sold for $175. What was the percentage of loss on the transaction?

Explanation / Answer

27)

C = (5/9)(F-32)

(F-32) = (9/5)C

F = (9/5)C + 32

Answer: 9/5 C + 32

28)

C = (5/9)(F-32)

C = (5/9)(75-32)

C = (5/9)43

C = 23.9 oC

Answer: 23.9
