Question

Xalatan should be stored in a temperature not to exceed 46 degrees Fahrenheit. What is this temperature in Centigrade?

Answer 1

`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.
