The harringtons go to a restaurant for lunch and their bill is $86.20. after 6.5% tax and tip, they pay a total of $100. if the
harringtons were exceptionally with their service, decide if their tip reflected this. explain your reasoning.

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one. the length of all the smaller ones is the same and is stored in the variable small. similarly, the length of all the larger ones is the same and is stored in the variable large. write a single expression whose value is the total area of this room. do not use any method invocations.

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much

Fast! find the length of cu. the triangles are similar. show your work.
