To find out how tall the demonstration calculator is, we first need to find the scale factor between the student calculators and the demonstration calculator.
The width of the keys on the student calculator is 14 millimeters, and the width of the keys on the demonstration calculator is 5.6 centimeters = 56 millimeters.
So, the scale factor is: 56 / 14 = 4.
Now, if the student calculators are 249 millimeters tall, we can find the height of the demonstration calculator by multiplying 249 by the scale factor:
249 * 4 = 996
Therefore, the demonstration calculator is 996 millimeters tall.
Pierce works at a tutoring center on the weekends. At the center, they have a large calculator to use for demonstration purposes that is a scale model of calculators available for the students to use.
Each key on the student calculators is 14 millimeters wide, and each key on the demonstration calculator is 5.6 centimeters wide. If the student calculators are 249 millimeters tall, how tall is the demonstration calculator?
