Sample Practice Test Questions

Word Knowledge
Walter's trove of vintage baseball cards was worth thousands of dollars.
cache
Valuable collection.
Arithmetic Reasoning

What is (z5)4?

z20

To raise a term with an exponent to another exponent, retain the base and multiply the exponents:

(z5)4
z(5 * 4)
z20

Word Knowledge
The extenuating circumstance of Calvin's illness caused the teacher to excuse his lateness.
mitigating
Partially excusing.
Mechanical Comprehension

The measure of how much of the power put into a machine is turned into movement or force is called:

efficiency

The efficiency of a machine describes how much of the power put into the machine is turned into movement or force. A 100% efficient machine would turn all of the input power into output movement or force. However, no machine is 100% efficient due to friction, heat, wear and other imperfections that consume input power without delivering any output.

Electronics Information

A capacitor is often used for which of the following purposes?

to maintain power in a circuit when the primary power source is disconnected

Capacitors store electricity and are used in circuits as temporary batteries. Capacitors are charged by DC current (AC current passes through a capacitor) and that stored charge can later be dissipated into the circuit as needed. Capacitors are often used to maintain power within a system when it is disconnected from its primary power source or to smooth out or filter voltage within a circuit.

Mechanical Comprehension

Friction between two or more solid objects that are not moving relative to each other is called:

static friction

Static friction is friction between two or more solid objects that are not moving relative to each other. An example is the friction that prevents a box on a sloped surface from sliding farther down the surface.

General Science

When compared to eukaryotic cells, prokaryotic cells are:

less complex

Cells are classified into one of two groups based on whether or not they have a nucleus. Eukaryotic cells have a nucleus, prokaryotic cells do not have a nucleus and therefore have a less complex structure than eukaryotic cells.

Word Knowledge
Epistolary most nearly means:
written
Contained or carried on in letters.
Word Knowledge
Gary believed the black foreboding sky was an inauspicious sign.
ominous
Not favorable.
Math Knowledge

Solve for b:
9b - 9 < \( \frac{b}{5} \)

b < 1\(\frac{1}{44}\)

To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the < sign and the answer on the other.

9b - 9 < \( \frac{b}{5} \)
5 x (9b - 9) < b
(5 x 9b) + (5 x -9) < b
45b - 45 < b
45b - 45 - b < 0
45b - b < 45
44b < 45
b < \( \frac{45}{44} \)
b < 1\(\frac{1}{44}\)
