QuestionPierce 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 18 millimeters wide, and each key on the demonstration calculator is 3.6 centimeters wide. If the student calculators are 255 millimeters tall, how tall is the demonstration calculator? A. 0.036 meter B. 51 meters C. 0.51 meter D. 9.18 meters Reset Next

Studdy Solution
Use the scale factor to find the height of the demonstration calculator.
Height of demonstration calculator $= \text{Height of student calculator} \times \text{Scale factor}$
$= 255 \text{ mm} \times 2 = 510 \text{ mm}$
Convert the height from millimeters to meters:
$510 \text{ mm} = 0.51 \text{ meters}$
The height of the demonstration calculator is:
$\boxed{0.51 \text{ meters}}$
