Name the number property illustrated by this equation: 4.78+(2.5+12.66)=4.78+(12.66+2.5) pleaese show your work or explain

This is the commutative property of addition

This property is the idea of adding any two numbers in any order you want. For example: 2+3 = 3+2 = 5

In this problem, we have 2.5+12.66 the same as 12.66+2.5

Ithink it’s b because it say 3 plastic rings and all the balls

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
