  13. 11. If , what is the value of ? Substitute p+3 as your x in the function f(x). Substitute p as your x in the function f(x). Answer: B. 15

  14. 12. How many prime numbers are between 1 and 15? between = 1 and 15 are not included Moreover, 1 is NEITHER prime nor composite. And 15 is composite. 2 3 4 5 6 7 8 9 10 11 12 13 14 Answer: D. 6

  15. 13. If a 4-meter tree casts a shadow that is 12-m long, how tall is an electric post that casts a shadow 36-m long? Ratio & Proportion ? 4 12 36

  16. 14.

  17. 15. Three circles are tangent externally to each other and have radii of 2 inches, 3 inches, and 4 inches, respectively. How many inches is the perimeter of the triangle formed by joining the centers of the three circles? Answer: D. 18

  18. 16. A sphere’s radius is increased by 50%. The volume will then be increased by how many times the original? Increasing by 50% means the new radius is 1.5times the original.

  19. 17. Solve for x: Quadratic Equation: Put all terms on one side of the equation. Check if the expression is factorable. Think of two factors of +12 whose sum is -8. Answer: D. +6 and +2

  20. 18. What is the domain of the function ? Set of all possible X values such that h(x) will be a real no. h(x) is a rational function. Recall: Rational Functions: watch out for the denominator. Denominator cannot be equal to zero. For h(x) above, what values of x will make the denominator zero? Therefore, domain is ALL REAL NOS.

  21. 19. Uncle gave to his children their allowance in the ratio 2:3:7. If the largest share is P840, how much is the smallest share? Partitive proportion 2 : 3 : 7 ? ___ : ___ : 840 Answer: C. 240

  22. 20. The sum of the ages of Ged, Billy and Karla is 90. If Ged is twice as old as Billy and Billy is thrice as old as Karla, how old is Ged? Ged’s age: 6 times of Karla’s age. 6(9) = 54. Answer: D. 54

  24. 22. Liezel’s percent score in her physics test was 80%. She counted her mistakes to be 9. What is the total number of items in the test? 9 mistakes = 20% of the total number of items Answer: C. 45

  25. 23. In some circuits, the voltage E can be calculated by the formula , where I = current in amperes, R = resistance in ohms, r is a constant, and n is the number of elements connected to the circuit. Express n in terms of the other variables.

  26. Solution 2: Solution 1: Answer is correct, but not in the choices. Answer: D.

  27. 24. Simplify

  28. 25. In the figure below, segment KJ bisects angle J. The measure of angle K is 40° and the measure of angle L is 20°. What is the measure of angle N? (a) 50° (d) 80° (b) 60 ° (e) 85° (c) 70°

  29. “measure of angle K = 40” • Angle MJK = 50 • Angle KJL = 50 also, because “KJ bisects angle J” • “Angle N is 20” Angle L = 180 –( 20 + 100)

  44. Trigonometry >In a right triangle, the side opposite the 30 degrees is ½ the hypotenuse. Answer: HYPOTENUSE = 2(70ft) =140ft E. 140 ft # 38

  45. Defined Operations the symbol is used to do the ff. operations 1) get the reciprocals 2) add them ANSWER: 2 + 3 = 5 (choice D) # 39

  46. Fractions >read the problem carefully. NS: ¾ of the remainder = ¾ of ½ = 3/8 # 40

  47. Exponential Equation P(n)= Po * 2n P(7) = 250* 27 =32,000 # 41

  48. 1st + 2nd + 3rd + 4th + 5th + X = 85 6 5(84) + X = 85 6 X= 90% # 42
