Debbie drew a scale drawing of a hotel. she used the scale 1 inch = 3 feet. if a room in the hotel is 4 inches in the drawing, how wide is the actual room?

The scale Debbie used was 1 inch = 3 feet. That means that every inch Debbie draws represents 3 feet.

Debbie drew a room that was 4 inches (wide, I'm assuming). That means you need to multiply 3 feet by 4 (for every inch that she drew):


The width of the room is 12 feet.

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
