Final answer:
The absolute value of 57°F is 57, as the absolute value represents the distance of a number from zero on the number line without considering direction.
Step-by-step explanation:
The student asked about the absolute value of the temperature in Indianapolis, Indiana, which was 57°F. In mathematics, the absolute value of a number is its distance from zero on the number line, regardless of direction. Therefore, the absolute value of 57 is just 57, written as |57| = 57.
The absolute value is always a non-negative number, so even if the temperature were below zero, its absolute value would still be presented without the negative sign.
