Answer:
4
Step-by-step explanation:
Each walk-in is $5, so 20 divided by 5 is 4. 4 classes.
What? That doesn't make sence! Any way if you mean 1997 to 2014 how many years.
40 cm.
let the length of the first part be 3x, second part be 4x, third part be 5x.
where x is a positive length in cm.
why 3x,4x and 5x ?
so that the ratio of lengths of the 3 parts be 3:4:5.
total length of the stick = 3x + 4x + 5x = 12x=96cm
so x=96/12 = 8cm
therefore the largest part of the stick (5x)= 5*8 =40cm
