ASVAB-SECTION-6 Online Practice Questions and Answers

Correct Answer: B

Correct Answer: C

Explanation:

Two angles that form a straight line add up to 180 degrees. If Angle 4 is 100 degrees than Angle 1 must be

80 degrees.

Correct Answer: A

Explanation:

The square root of 49 is 7; the square root of 64 is 8. 7 ÷ 8 = 7⁄8.

Correct Answer: B

Explanation:

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

Correct Answer: C

Explanation:

To solve the equation x2 = 3x + 10, turn it into an equation equal to 0, find the two factors of the new

equation, and then set each factor equal to 0, to solve for x.

Step 1: Move all expressions to one side of the equal sign. Change the signs of terms that are moved. x2 - 3x - 10 = 0 Step 2: Find the two factors that you would multiply to produce this polynomial. Do this one expression at a time. What gives you x2? The answer is x times x. Therefore, place an x at the beginning of each factor. (x)(x) Next find the two numbers you would multiply to get 10. The numbers could be 10 and 1, or 5 and 2, but remember that the two numbers also have to produce 3, the middle term in the polynomial. The difference between 5 and 2 is 3. Therefore 5 and 2 are the numbers that complete the factors (x - 5)(x + 2) Now decide the signs that belong in each factor. The appearance of -10 in the polynomial means that 5 and 2 have different signs. The -3x in the polynomial indicates that 5 (the larger number) has the minus sign, and that 2 has a plus sign. Thus (x - 5)(x + 2) Step 3: Set each factor equal to zero and solve the equations. x - 5 = 0x + 2 = 0 x = 5 x = -2

Correct Answer: A

Explanation:

Multiply 0.0375 by 4% (or 0.04).

0.0375 x 0.04 = 0.001500 = 0.0015

Note that the product has as many decimal places as there are in the multiplicand and multiplier combined,

but the two final zeros may be dropped since they are to the right of the decimal point and at the end.

Correct Answer: C

Explanation:

2.5 x 33= 2.5 (3 x 3 x 3) = 2.5 x 27 = 67.50.

Correct Answer: B

Explanation:

A prime number is a number that can be divided evenly by itself or by one, but not by any other number.

Choices 27, 8 and 4 can all be divided evenly by other numbers.

Correct Answer: A

Explanation:

If two exponents have the same base, you can multiply them by keeping the base and adding the

exponents together.

Correct Answer: A

Explanation:

202= 400, and 302= 900, so the range of 20 to 30 is correct.
