There are 3 red marbles for every 8 blue marbles in a huge jar of marbles. If there are 27 total red marbles in the jar, how many blue marbles would you expect in the
jar?

The hypotenuse of a 45 -45 -90 triangle measure 7 square root 2 units

2x - 20 = 32 20 - 3x = 8 6x - 8 = 16 -13 - 3x = -10

The figures below are made out of circles, semicircles, quarter circles, and a square. 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).
