They are drawn as accurately as possible EXCEPT when it is stated in a specific problem that its figure is not drawn to scale. All figures lie in a plane unless otherwise indicated. All numbers used are real numbers. :RA :Q5 a 1. 1 - - = b 1 - a b - a (a) ----- (b) ----- b b (c) 1 - a (d) b - a (e) It cannot be determined from the information given. :RCB :Q6 1 4 - 6 2. ---- = 1 2 -- 12 (a) 2 (b) 2 1/2 (c) 4 (d) 1/4 (e) 1/2 :RCA :Q5 3.

You are to compare the two quantities and choose the correct answer A if the quantity in A is greater; B if the quantity in B is greater; C if the two quantities are equal; D if the relationship cannot be determined from the information given. :RA Notes: 1. In certain questions, information concerning one or both of the quantities to be compared is centered. 2. In a given question, a symbol that appears in both columns represents the same thing in Column A as it does in Column B. 3. Letters k, n, and a stand for real numbers. :RA :Q9 Column A Column B a 8. - = c b = c b a b :RCA :Q9 Column A Column B ___ 9. \/729 27 :RCC :Q9 Column A Column B 10. ky = 40 k + y 20 :RCD :Q9 Column A Column B 11. 2rPI = 30 r 6 :RCB :SB :SP140080168126112126140080 :SH1717B C :SH1022A :SH18183y + 15 :SH13145y + 7 :SH13258y - 5 :SF :Q9 Column A Column B 12. <A = <B = <C y 4 :RCC :SD :Q9 :SB :SP140080168126112126140080 :SH1717B C :SH1022A :SH18183y + 15 :SH13145y + 7 :SH13258y - 5 :SF Column A Column B 13. <A = <B = <C perimeter 60 :RCA :SD :Q9 Column A Column B ___ / 1 14. / --- 1 \/ 289 :RCB :Q9 :SB :SP091063133063091128155128 :SP155128091063091063091063 :SH161840^ k^ :SH0918y^ :SF Column A Column B 15. k y :RCD :SD :Q9 :SB :SP091063133063091128155128 :SP155128091063091063091063 :SH161840^ k^ :SH0918y^ :SF Column A Column B 16. 40 y^ :RCC :SD :Q9 :SB :SP159127112127112080159127 :SH1717B b A :SH1417a :SH1017C :SH1222c :SH1920AB PERPENDICULAR BC :SF Column A Column B 2 2 2 17. a + b c :RCC :SD :Q9 :SB :SP159127112127112080159127 :SH1717B b A :SH1417a :SH1017C :SH1222c :SH1920AB PERPENDICULAR BC :SF Column A Column B 18. <CAB <CBA :RCB :SD :Q9 Column A Column B 3 19. 1/4 (1/4) :RCA :Q9 Column A Column B 20. 9y = 189 y/3 8 :RCB :Q9 Column A Column B 4 2 21. 5 = 10 (A) A 9 :RCB :Q9 Column A Column B 22. y < 6 6 5 y 6y :RCB :Q9 Column A Column B ____ 2 23. \/.004 .02 :RCA :Q9 Column A Column B 0.8 24. 0.4 --- 2 :RCC :Q9 Column A Column B 3 25.
