• Question 151:

  The suburb of Hewitt has a private subdivision that has a pool in the shape of a quadrilateral.

  If the subdivision wants to put a lifeguard on each side of the pool, how many lifeguards will be needed?

  A. eight

  B. six

  C. four

  D. three

  Correct Answer: C

  Explanation:

  Since a quadrilateral is a four-sided figure, the subdivision will need four lifeguards. A quadrilateral, by

  definition, has four sides.

  Whether the sides are parallel – a parallelogram – or if all four sides are equal and all four angles are right

  angles – a square – there are still four sides, and, therefore, four lifeguards.

• Question 152:

  What is the product of (z + 2) (2z - 3)?

  A. 3z - 6

  B. z + 4z - 3

  C. z2 + 4z - 6

  D. 2z2 + z - 6

  Correct Answer: D

  Explanation:

  An easy way to perform the multiplication is to do four separate multiplications. Then the procedure looks

  like ordinary multiplication in arithmetic.

  Multiply (2z-3) by 2

  Multiply (2z-3) by z

  Add the partial products as you do in arithmetic.

  

• Question 153:

  If b - 3 = 7, then b is equal to __________.

  A. 10

  B. 4

  C. 21

  D. 8

  Correct Answer: A

  Explanation: This equation means "some number, decreased by 3, is equal to 7." b - 3 = 7 To arrive at a true statement for b, we want to eliminate - 3 on the left side of the equation. We do this by adding 3 to both sides of the equation, undoing the subtraction on the left side. When we add 3 to both sides, we are keeping the statement an equation. (b - 3) + 3 = 7 + 3 By simplifying both sides, we isolate b and thus find the solution. b = 10

• Question 154:

  √-9 is an example of a(an) __________.

  A. real number

  B. imaginary number

  C. irrational number

  D. sloping number

  Correct Answer: B

  Explanation:

  The square root of a negative number doesn't exist as far as real numbers are concerned. In mathematics,

  this is called an imaginary number.

• Question 155:

  What is the prime factorization of 100?

  A. 2 x 50

  B. 22 x 52

  C. 4 x 25

  D. 252

  Correct Answer: B

  Explanation:

  100 = 4 x 25 = (2 x 2) x (5 x 5) = 22 x 52.

• Question 156:

  The sum of the measures of the angles of a parallelogram is __________.

  A. 360 degrees

  B. 540 degrees

  C. 180 degrees

  D. 720 degrees

  Correct Answer: A

  Explanation:

  All quadrilaterals have angles that total 360 degrees.

• Question 157:

  

  The figure above is a(an) __________.

  A. parallelogram

  B. obtuse triangle

  C. trapezoid

  D. rectangle

  Correct Answer: C

  Explanation:

  Trapezoid is a convex quadrilateral with at least one pair of parallel sides.

• Question 158:

  What's the volume of a box measuring 12- inches long by 8-inches deep by 10-inches high?

  A. 960 cubic inches

  B. 128 cubic inches

  C. 42 cubic inches

  D. 288 cubic inches

  Correct Answer: A

  Explanation:

  Volume equals length times width times height (V = lwh). 12 x 8 x 10 = 960 cubic inches.

• Question 159:

  If 2 + x ≥ 15, what's the value of x?

  A. x < 13

  B. x > 13

  C. x ≥ 13

  D. x ≤ 13

  Correct Answer: C

  Explanation:

  Solving this equation doesn't require multiplying or dividing by a negative number, so the inequity sign

  remains the same.

• Question 160:

  If a circle has a radius of 15 feet, what is its circumference most nearly?

  A. 24 feet

  B. 72 feet

  C. 94 feet

  D. 36 feet

  Correct Answer: C

  Explanation:

  Circumference equals π times diameter, and diameter is equal to two times the radius.

  Or C= πd, and d = 2r. C = π30.

  If you round π to 3.14, the answer is about 94.2 or about 94 feet.
