Hillview Elementary School has 3 sixth-grade classes of 22 students each. On a Friday, the entire 6th grade went on a field trip to the science museum. Some of the 6th graders were absent that day. If s represents the number of 6th grade students who were absent on that Friday, which of the following expressions shows how many 6th graders went to the science museum?

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
