Answer:

#7.8^@"C"#

Explanation:

The Fahrenheit and Celsius temperature scales are connected by the equation

#color(blue)(ul(color(black)(t[""^@"C"] = 5/9 * (t[""^@"F"] - 32))))#

This tells you that in order to convert degrees Fahrenheit to degrees Celsius, you must

  • subtract #32# from the temperature in degrees Fahrenheit
  • multiply the result by #5/9#

In your case, you must convert #46^@"F"# to degrees Celsius, so simply plug this value into the equation and solve.

#t[""^@"C" ] = 5/9 * (46^@"F" - 32)#

#color(darkgreen)(ul(color(black)(t[""^@"C"] = 7.8^@"C")))#

The answer is rounded to two sig figs, the number os fig figs you have for the temperature in degrees Fahrenheit.
