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 15 milliliters wide, and each key on the demonstration calculator is 4.5 centimeters wide. If the student calculators are 250 millimeters tall, how tall is the demonstration calculator?

x= 149. 24+7=31. 180-31=149

your welcome

the correct answer is x/3+10≥32

hope this !

80 the answer is 80

step-by-step explanation:

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
