15% of the toddlers in a preschool class drink water with their lunch. how many toddlers are in the class if 3 toddlers drink water with their lunch? (a) draw a model for the situation (if you prefer to use a 100-grid model or ratio table model, that’s fine too! ) and label the “part,” “whole,” and “percent.”

The ratio pv to nrt is plotted against pressure for ch4 at 0°c and 200°c. why does the curve for 0°c drop below the horizontal line for an ideal gas whereas the curve for 200°c does not?

Which of those sequences is a geometric sequence

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.
