Each of the points on the graph represents the position of a rider on The Screamer. Select the correct diagram and description to match

• 
• (a): Above ground just past the highest point; (b): Just below ground; (c): Back to the starting point.

• (a): Below ground just past the highest point; (b): Just above ground; (c): Back to the starting point.

• (a): Above ground just before the highest point; (b): Just below ground; (c): At the lowest point.

While trying to measure the height of a tree, Julie noticed that a 3.5-foot post had a 4.25-foot shadow. If the tree’s shadow is 100 feet long, how tall is the tree?

• ≈ 82.4 feet

• ≈ 121.4 feet

• ≈ 96.8 feet

• ≈ 37.9 feet

Maria Elena is collecting college pennants. She has five fewer pennants from Washington campuses than from California campuses and twice as many pennants from California campuses as from Pennsylvania campuses. She has 40 pennants in her collection. Write a system of equations to find the number of Pennants from each state

• C + W + P = 40, W = C − 5, C = 2P; 18 from California, 13 from Washington, and 9 from Pennsylvania

• C + W + P = 40, W = C + 5, C = 2P; 15 from California, 16 from Washington, and 9 from Pennsylvania

• C + W + P = 40, W = C − 5, 2C = P; 18 from California, 8 from Washington, and 14 from Pennsylvania

• C + W + P = 40, W = C − 5, C = 2P; 18 from California, 9 from Washington, and 13 from Pennsylvania
