Wreck It Ralph is planning to build a mega ramp for Princess Penelope's candy race track. Using the Pythagorean Theorem, what would the hypotenuse of the ramp be if the adjacent side (a) is 8 feet and the opposite side (b) is 6 feet.
Pythagorean Theorem: a^2 + b^2 = c^2 8^2 + 6^2 = c^2 (8x8) + (6x6) = c^2 64 + 36 = c^2 100 = c^2 The square root of 100 is 10; c = 10. So, the hypotenuse of the mega ramp will be 10.
Mario is making a rectangular, picture frame for a photo of Princess Peach. The photo is 8 inches by 10 inches. If the wood for the frame cost 50 cents an inch, how much will the wood for the frame cost? A. $9.00 B. $18.00 C. $15.00 D. $40.00
Step 1: Find out how much you need for the frame by using the perimeter formula for a rectangle: P = 2(L+W) (P is Perimeter / L is Length / W is Width) P = 2(8 + 10) P = 2(18) P = 36 inches total of wood needed for the frame Step 2: Now that you have the perimeter of your frame and know that it is 50 cents per inch. You can multiply $0.50 by 36 inches of wood needed. $0.50 x 36 inches = $18.00 Answer: B
