A stack of ten musical disks is 1.15 cm tall. What is the average thickness of one disk? To the nearest whole number, how many disks will be in a stack that is 5 cm tall?

Respuesta :

Let t be the thickness of one disk.

A stack of ten disks is 10t cm tall, so we have

[tex]10t = 1.15 \iff t = \dfrac{1.15}{10}=0.115[/tex]

So, you can stack approximately

[tex]\dfrac{5}{0.115}\approx 43[/tex]

disks on a 5cm tall stack.
