ASVAB-SECTION-6 Online Practice Questions and Answers

Correct Answer: D

Correct Answer: C

Correct Answer: D

Explanation: Step 1: Subtract 2 from each side of the equation in order to eliminate -2 from the left side. (You are undoing the addition.) 3x + 2 - 2 = -13 - 2 3x = -15 Step 2: Now divide each side by 3 to find x. (You are undoing the multiplication.) 3x/3 = -15/3 x = -5

Correct Answer: D

Explanation:

If the circle passes through all four vertices of the rectangle, its diameter will be a diagonal of the rectangle.

Since a rectangle's angles are right angles, the diagonal for n is a right triangle with two sides of the

rectangle. Let x = the length of the diagonal. By the Pythagorean Theorem, in a right triangle the square of

the length of the hypotenuse is equal to the sum of the squares of the legs.

x2 = 82 + 62

x2 = 64 + 36

x2 = 100

x2 = 100

means that x times x=100.

Therefore, x = 10 feet.

But 10 is a diameter of the circle. A radius of a circle is one-half the diameter. Hence, the radius is 5 feet.

Correct Answer: C

Explanation:

Circumference equals π x diameter, and diameter is equal to two times the radius. Or C = π x d, and d =

2r. C = π x 24.

If you round π to 3.14, the answer is about 75.36 or about 75 feet.

Correct Answer: D

Explanation:

Angles measuring more than 90 degrees are obtuse angles.

Correct Answer: B

Explanation:

(y2)3 is the same as (y2)(y2)(y2).

Multiply exponents with the same base by keeping the base and adding the exponents: (y2) (y2) (y2) = y6.

Correct Answer: A

Explanation:

Isolate x by dividing each side of the equation by –5:

-5x ÷ -5 = 25 ÷ -5

x = -5

Correct Answer: C

Explanation:

The area of a circle equals π times the radius squared. The radius is 1⁄2 the diameter.

A = πr2. A = π62= π36.

If π is approximately 3.14, the area of the circle is approximately 3.14 x 36 or 113 feet.

Correct Answer: A

Explanation:

The x access is intersected at the point where the y-coordinate is 0 (y= 0). Substitute 0 for the y variable in

the equation.

3x + 7y = 21 = 3x + 7(0) = 21 = 3x = 21.

Therefore, x = 7. The point's coordinates are (7, 0).
