Question 2 - Brianna spends 7 3/5 hours in school each day. Her lunch period is 30
minutes long, and she spends a total of 42 minutes switching rooms between classes.
The rest of her day is spent in 6 classes that are all the same length. How long is each
class?

64 minutes

Step-by-step explanation:

7⅗ hours = 7⅗ × 60 min

= 38/5 × 60

= 456 minutes

456 - 30 - 42 = 384 minutes for 6 classes

384/6 = 64 minutes per class

yes. we do proportions in probabilities.

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
