1. There is an assignment due tomorrow for lesson 86 evens and a test #12 coming up on Friday. 2. The warmup problems include solving an equation for y, finding a percentage of another percentage, and calculating distance traveled at a rate using full and partial tank amounts. 3. The lesson discusses volume formulas for prisms, cylinders, cones and pyramids. Examples are given to find the volumes of different shapes using the appropriate formulas.

- 2. Lesson 86.notebook April 22, 2014 Lesson 86 WarmUp: 1) Solve for y: y - 7 = 2x - 3 2) Find 33 1/3% of 4/5 of $4.50 3) If a car can travel 192 miles when its gas tank is 75% full, then how far can it travel at that same mileage rate on a FULL tank of gas? Find the volume in #4-5: 4) A rectangular prism with measures: L = 8 in; W = 6 in; H = 10 in 5) A cylinder with measures: R = 4 cm; H = 9 cm
