Brian is a farmer keeping chickens. Each day, he collects 140 eggs. How many trays of eggs does he collect in 6 days, given that one tray carries 30 eggs?

  • 28

  • 84

  • 840

  • 48

Correct answer: 28

Let's find how many total eggs Brian collects in 6 days, since we know he collects 140 eggs each day.

6 × 140 = 840 eggs

Now divide by 30, since there are 30 eggs per tray.

840/30 = 28 trays

What is the best definition of the italicized word in the sentence below?

Even though she had been grounded the day before, Terra's mother gave her a reprieve so she could attend her senior prom.

  • Pardon

  • Excoriation

  • Continuation

  • Layover

Correct answer: Pardon

A reprieve is a temporary pardon from punishment, as Terra's mother temporarily postponed Terra's punishment so that she could attend the prom. Therefore, pardon is the best answer.

Excoriation is the act of scratching or removing the skin or outer layer of something. Continuation is the act of carrying something over for a period of time and is an antonym of reprieve. Layover is a period of rest before continuing on a journey.

126.

What do machine screws use to prevent a nut from loosening?

  • Lock washer

  • Gasket

  • Hex nut

  • Thread tape

Correct answer: Lock washer

Lock washers have the ability to prevent nuts from loosening. When the nut is tightened on the machine screw, the lock washer becomes compressed under the nut and keeps the nut from loosening.

Gaskets are used to prevent leakage between two surfaces. Hex nuts are hexagonal-shaped nuts and are not used to keep other nuts from loosening. Thread tape allows two pieces to be screwed deeper together but is not typically used to keep nuts from loosening.

127.

Which of the following is a sedimentary rock?

  • Coal

  • Granite

  • Obsidian

  • Slate

Correct answer: Coal

Coal is formed when pressure and heat are applied to dead plants, forcing out oxygen and causing chemical and physical changes. The plant debris usually gathers in a swamp environment.

Granite and obsidian are igneous rocks, which form from the hardening of magma. Slate is a metamorphic rock formed when rock material is altered through temperature, pressure, or chemical processes.

A store offers a 10% discount on two pairs of soccer shoes when any 5 pairs are bought. A soccer club manager bought 20 pairs. If the cost of one pair of shoes is $60, find the total amount paid for the shoes.

  • $1,152

  • $2,280

  • $1,188

  • $1,170

Correct answer: $1,152

Remember that for every 5 pairs of shoes, 2 are given a 10% discount.

Let's find out how many pairs are discounted when the soccer club manager buys 20 pairs.

20/5 = 4 × 2 = 8 pairs are sold at a 10% discount

After the 10% discount, 100% - 10% = 90% of the price is paid.

Now we know that 12 pairs are bought at full price ($60), and 8 pairs are bought at 90% of the price.

(12 × $60) + 8(0.90 × $60) = $720 + $432 = $1,152

129.

Read the passage and then answer the following question.

Which of the following options best explains why Andy dug a tunnel?

  • To escape prison

  • To hide his money

  • To bury his victims

  • To keep his mind occupied

Correct answer: To escape prison

Sentence 2 states that Andy dug a secret tunnel that allowed him and Red to regain their freedom. You can determine that the purpose for digging the tunnel was to escape from prison.

The remaining answer options are incorrect. There are no references in the passage to the fact that Andy had to hide his money, bury his victims, or keep his mind occupied.

134.

A line on the coordinate grid has a slope of 3. One of the points on the line is (0, -3). What is the correct equation of this line?

  • y = 3x - 3

  • y = 1/3x + 3

  • y = 3x

  • y = 1/3x - 3

Correct answer: y = 3x - 3

Use the slope-intercept equation for a line, y = mx + b, where m equals the slope of the line and b is the y-intercept, where the line intersects the y-axis.

Since the slope, m, equals 3, then y = 3x + b.

Since a point on the line is (0, -3), we know that the y-intercept is -3.

Therefore, y = 3x - 3.

135.

If a wedge moves 2.5 inches every time it moves and the load moves 1.25 inch, what is the mechanical advantage of the wedge?

  • 2

  • 1.25

  • 3.75

  • 3.13

Correct answer: 2

Mechanical advantage is a measure of the force amplification achieved by, in this case, using a wedge. In order to find the mechanical advantage of a wedge, use the following formula: MA = Effort Distance ÷ Load Distance.

MA = 2.5 ÷ 1.25

MA = 2

Read the passage and then answer the following question.

According to the passage, what causes an anthropogenic climate change?

  • Humans

  • Tornadoes

  • Hurricanes

  • The sun

Correct answer: Humans

The answer to this question can be found directly in the passage’s content. The definition of anthropogenic is found in Sentence 4, which indicates that anthropogenic is a term used to mean exclusively human-caused.

The passage does not mention that tornadoes, hurricanes, or the sun causes an anthropogenic climate change, so all of these answers are incorrect.

If x = 12 and y = 6, what is the value of 7x(x + y)?

  • 1512

  • 1204

  • 982

  • 1476

Correct answer: 1512

Since we know the values of x and y, insert them into the equation.

7x(x + y)

x = 12, so insert the value of x.

7(12)(12 + y)

y = 6, so insert the value of y.

7(12)(12 + 6)

Solve.

7(12)(18) = 1512

140.

In a home, what is always used to control the hot side of the circuit?

  • Switch

  • Fuse

  • Ground wire

  • Conduit

Correct answer: Switch

Homes always use switches to control a circuit’s hot side, or the side that supplies the circuit’s current. Switches are made out of plastic, which is a poor conductor of electricity and heat, to protect the user.

The steel sheath on electrical wiring is known as a conduit, and the ground wire is used as an alternative path for the current in case of malfunction. Fuses are used to break the circuit in case too large a current flows through it.
