Final answer:
Bobby used a scale drawing technique with a scale factor of 1:3 for his pizza restaurant drawing. This method applies a consistent ratio to shrink or enlarge objects in a drawing in proportion to their actual size.
Step-by-step explanation:
Bobby used a scale factor to create a scale drawing of a pizza restaurant. If the real kitchen is 27 meters long and its representation in the drawing is 9 meters long, then Bobby used a scale factor of 1:3 (since 27m divided by 9m equals 3). Essentially, every 1 meter in the drawing represents 3 meters in real life.
To apply a similar principle to the examples given for practice:
- With a scale factor of 1/150, the distance from Anna's room to the kitchen in her diagram would be 15 meters divided by 150, which equals 0.1 meters, or 10 centimeters.
- Using a scale factor of 1/200 to find the dimensions of an actual floor, you would multiply the drawing measurements by 200.
- If Jonah uses a scale of 0.5 centimeter equaling 4 millimeters, then a 16-millimeter spider would be represented by 2 centimeters in his drawing (because 16mm divided by 4mm equals 4, and then that multiplied by 0.5cm).
