Agroup of students recycles 7 2/3 pounds of glass and 9 3/4 pounds of paper. how many pounds of paper and glass did the kids recycle all together?

17 5/12 lb total

Step-by-step explanation:

Find the total weight of the materials recycled:

7 2/3 lb + 9 3/4 lb

Here the LCD is 12.  (Both 3 and 4 divide evenly into 12.)

Rewriting 7 2/3 lb + 9 3/4 lb with the LCD 12, we get:

7 8/12 lb + 9 9/12 lb, or 16 17/12 lb.

The fraction here must be reduced.  We get

17 5/12 lb total      (Recognize that 17/12 = 1 5/12.)

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
