Final answer:
The question pertains to Mathematics and involves understanding scale drawings where a specific unit of measure on the drawing represents a larger unit of measure in reality. A scale factor is used to determine the scaled and actual sizes. A unit scale as a ratio helps to convert measurements from a drawing to real-life size and vice versa.
Step-by-step explanation:
The subject of this question is Mathematics, specifically focusing on the concept of scale drawings and the scale factor. Scale drawings are used to represent real-life sizes in a more manageable way, typically for purposes like architecture, engineering, or in this case, illustrating a crime scene. The scale of a drawing indicates the proportion by which real-life measurements are reduced to fit on paper.
For example, if we have a scale where 1 inch on the drawing represents 10 feet in real life, and we want to find out how much real distance is represented by inches in a different drawing, we start with the unit scale. Given that a scale of 1 inch equals to 10 feet, if a drawing measures 10 inches by 14 inches, the actual dimensions of the building would be 100 feet by 140 feet, as each inch represents 10 feet in reality.
In review problems, the same principles are applied. For instance, if Haley made a scale model of her school building and the scale was 1 inch equals 6 feet, to find out the height of the building on her scale model which is 30 actual feet tall, you would divide 30 feet by 6 feet per inch to get a result of 5 inches. This is because the scale factor tells us how many times smaller the drawing is than the actual object.
