Approximate the height of each of the three portions 13-18 age group 25 hours 19-24 age group 5 hours 25-30 age group 10 hours The ratio in question is 25 15 or 5 3. 11. The correct answer is C . The ring s height is equal to its radius. To determine Quantity A the surface area of the outside of the ring multiply the ring s circumference 2pr by its height r SA 2pr r 2pr2 To determine Quantity B twice the ring s circular area multiply 2 by the base s area 2pr2. As you can see the two quantities are equal. 12. The correct answer is C . The average arithmetic mean of any two numbers is half their sum. Regardless of the values of x and y Quantity A will always equal Quantity B x - 1 y 1 x y 2 2 13. The correct answer is B . There are six possible sequences and so Quantity A .
