There is a 30/100 of a liter of orange juice in one container and 5/10 of pineapple juice in another container. if mrs. smith combines the two juices, how much orange-pineapple juice will she have?

8/10
or 80/100
you have to multiply 5/10 by 10

Arhombus is a quadrilateral.

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.
