A precalculus course has 32 class meetings that last 1.75 hours each. How many minutes does the course meet in a semester. Express your answer in scientific notation.

Step-by-step explanation:

If one pre calculus class lasts 1.75hours

32 class meetings will last 32*1.75 = 56 hours

Hence the number of hours that the precalculus meets in the semester is 56 hours. In order to know the number of minutes the same class meet, we will convert 56 hours to minutes.

Since 1 hour = 60 minutes

56hours = (56*60) minutes

56hours = 3360 minutes

Expressing 3360 in scientific notation means expressing it in exponential form.

3360 = 3.36 * 10³ minutes

Hence the precalculus class meets for  3.36 * 10³ minutes in a semester.

answer: 5100 just subtract
