Sarah has 11 feet of red fabric and 25 feet of blue fabric. How many yards of fabric does she have altogether?
Sarah has
yards of fabric.

12 yards of fabric

Explanation:

11+25=36 feet of fabric. However, the question up is asking for the answer in yard and we know one yard is three feet. So convert 36 feet to yards. Ask yourself, how many times can theee go into 36? 36/3=12. Therefore, the answer is 12 yards.

12 yards

Explanation:
To solve this problem we must first add the length of the red fabric and the blue fabric together.

11 feet of red fabric + 25 feet of blue fabric =
36 feet of red and blue fabric total

Now that we have found how many feet of fabric Sarah has in total, we must find how many yards it equals.

1 foot = 0.333... yards
30 feet = 10 yards
36 feet = 12 yards

Therefore, Sarah has 12 yards of fabric.

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.
