I have 2 questions.
#1. how do we figure fahrenheit to celsius temperature?
#2 where did the word coxswain originate?
Thankyou.
ClassBrain Response:
Here's your answer to question #1:
To convert temperature from Fahrenheit to Celsius use this formula:
Tc=(5/9)x(Tf32)
Tc=temperature in degrees Celsius
Tf=temperature in degrees Fahrenheit
So for example, if you were trying to figure out what 82º Fahrenheit would be in ºCelsius, you would write the equation like this:
Tc=(5/9)x(8232)
So how do you know which part of the equation to solve first?
You would perform the order of operations using the infamous acronym P.E.M.D.A.S. (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction). Solve the problem in this order.
Tc=(0.5555556)x(50)
Tc=27.77778
Tc=27.78ºC
To convert from Celsius to Fahrenheit, use this equation:
Tf=(9/5)xTc+32
Tc=temperature in degrees Celsius
Tf=temperature in degrees Fahrenheit
So, if you were to take 25º Celcius and convert it to ºFahrenheit, the equation would look like this:
Tf=(9/5)x25+32
Tf=(1.8)x25+32
Tf= 45+32=77ºF
Now, to answer your second question:
The word "coxswain" is a Middle English nautical term that means, a person who usually steers a ship's boat and has charge of its crew. Coxswain comes from the word cokswaynne.
Here's the history:
Cok + Swaynne = cockboat + swain
A cockboat is a small rowboat especially one used to ferry supplies from ship to shore. The word "cockboat" comes from the words cok and boot. Cok is also Middle English, but even that word comes from the word coque. The word Coque is AngloNorman. Other translations of the word are caudica, caudex, and caudic, which means tree trunk. (Probably what the boat was originally fashioned from.) Boot simply means boat.
A swain is a country lad, especially a young shepherd. It could also mean beau. Swain is Middle English as well, but comes from the Old Norse word, sveinn.
