Questions and Answers
  • 1. 

    If a = 1.9 and b = 0.6, what is a/b (round to 2 decimal places)?

    • A.

      0.32

    • B.

      2.5

    • C.

      3.17

    • D.

      1.3

    Correct Answer
    C. 3.17
    Explanation
    To find the value of a/b, we divide the value of a (1.9) by the value of b (0.6). Dividing 1.9 by 0.6 gives us approximately 3.17 when rounded to 2 decimal places. Therefore, the correct answer is 3.17.

    Rate this question:

  • 2. 

    How much is 1/4 of the sum of 260 and 64?

    • A.

      324

    • B.

      16

    • C.

      65

    • D.

      81

    Correct Answer
    D. 81
    Explanation
    To find 1/4 of the sum of 260 and 64, we first need to calculate the sum which is 324. Then, we divide this sum by 4 to find the 1/4 value. Therefore, 1/4 of 324 is 81.

    Rate this question:

  • 3. 

    Which number is evenly divisible by 7?

    • A.

      674

    • B.

      672

    • C.

      673

    • D.

      671

    Correct Answer
    B. 672
    Explanation
    672 is evenly divisible by 7 because it can be divided by 7 without leaving a remainder.

    Rate this question:

  • 4. 

    What is 2/3 of 192?

    • A.

      108

    • B.

      118

    • C.

      138

    • D.

      128

    Correct Answer
    D. 128
    Explanation
    To find 2/3 of 192, we can multiply 192 by 2 and then divide the result by 3. This gives us (192 * 2) / 3 = 384 / 3 = 128. Therefore, the correct answer is 128.

    Rate this question:

  • 5. 

    How many feet are in 2/3 of a mile?

    • A.

      1,760 Feet

    • B.

      8,520 Feet

    • C.

      5,280 Feet

    • D.

      3,520 Feet

    Correct Answer
    D. 3,520 Feet
    Explanation
    There are 5,280 feet in a mile. To find 2/3 of a mile, we can multiply 5,280 by 2 and then divide by 3. This gives us 3,520 feet, which is the correct answer.

    Rate this question:

  • 6. 

    In how many different ways can the cars of a three-car train be arranged?

    • A.

      6

    • B.

      10

    • C.

      30

    • D.

      20

    Correct Answer
    A. 6
    Explanation
    To calculate the number of different ways the cars of a three-car train can be arranged, you can use the concept of permutations. In this case, you want to arrange three distinct cars, so you would use a permutation of 3 objects taken 3 at a time.

    The formula for permutations is:

    [P(n, r) = frac{n!}{(n - r)!}]

    where:
    - (P(n, r)) is the number of permutations of (n) objects taken (r) at a time.
    - (n!) is the factorial of (n), which is the product of all positive integers from 1 to (n).
    - ((n - r)!) is the factorial of (n - r).

    For your three-car train, you have three cars, so (n = 3), and you want to arrange all three, so (r = 3).

    Using the permutation formula:

    [P(3, 3) = frac{3!}{(3 - 3)!} = frac{3!}{0!} = frac{6}{1} = 6]

    There are 6 different ways to arrange the cars of the three-car train.

    Rate this question:

  • 7. 

    What's the width of a cube whose height is 10 inches?

    • A.

      20 Inches

    • B.

      10 Inches

    • C.

      100 Inches

    • D.

      5 Inches

    Correct Answer
    B. 10 Inches
    Explanation
    The width of a cube is equal to its height, so if the height of the cube is 10 inches, then the width would also be 10 inches.

    Rate this question:

  • 8. 

    How would you write 4^3 (4 to the 3rd power) without an exponent?

    • A.

      16

    • B.

      64

    • C.

      12

    • D.

      43

    Correct Answer
    B. 64
    Explanation
    To write 4^3 without an exponent, we need to multiply 4 by itself three times. This can be written as 4 × 4 × 4, which equals 64.

    Rate this question:

  • 9. 

    Which of the examples below shows the "Multiplicative Inverse"?

    • A.

      2 + (-2) = 0

    • B.

      2 x (1/2) = 1

    • C.

      2 + 0 = 2

    • D.

      2 x 0 = 0

    Correct Answer
    B. 2 x (1/2) = 1
    Explanation
    The example 2 x (1/2) = 1 shows the "Multiplicative Inverse" because when a number is multiplied by its multiplicative inverse, the result is always 1. In this case, 2 is multiplied by the multiplicative inverse of 2, which is 1/2, resulting in 1.

    Rate this question:

  • 10. 

    What is the prime factorization of 100?

    • A.

      10 x 10

    • B.

      2 x 2 x 5 x 5

    • C.

      2 x 2 x 25

    • D.

      2 x 5

    Correct Answer
    B. 2 x 2 x 5 x 5
    Explanation
    The prime factorization of 100 is 2 x 2 x 5 x 5 because it can be expressed as a product of prime numbers. The number 100 can be divided by 2, resulting in 50. Then, 50 can be divided by 2 again, resulting in 25. Finally, 25 can be divided by 5, resulting in 5. Therefore, the prime factorization of 100 is 2 x 2 x 5 x 5.
