Question

The temperature of a liquid in an experiment changes by -10.4 degrees F from the beginning of the experiment to the first check. After making some adjustments, the scientist checks the temperature again later and finds that it is 17.7 degrees F, which is 1/3 what it was at the time of the first check. What was the initial temperature of the liquid? Enter answer as a decimal.

Answer 1

Step-by-step explanation:

17.7° = 1/3 of first check.

the temperature at the first check was therefore

3×17.7 = 53.1° F

and the temperature at the first check was 10.4° less than the initial temperature.

so, the initial temperature was 53.1 + 10.4 = 63.5° F
