### Calculating Areas and Perimeters

Jamie, a contestant on "America's got gumbo" cooking show, wants to prepare a chocolate pyramid dessert. If Jamie chooses a pyramid mold with a volume of 1/8 cubed feet and a height of 0.5 feet, what would be its base area?

A. 4.

B. 0.25.

C. 1.333

D. 0.75

E. N.

Explanation
The correct answer is (D) - 0.75

The formula for calculating a pyramid's volume is:
Volume of a pyramid = 1/3*base area*height = (base area*height)/3

Isolate the 'base area' in the formula:
1. Multiply both sides of the formula by 3:
3*Volume of a pyramid = 3*1/3*base area*height
3*Volume of a pyramid = base area*height
2. Divide both sides of the formula by 'height':
3*Volume of a pyramid/height = base area*height/height
3*Volume of a pyramid/height = base area
=> Base area = 3*volume of the pyramid / height

Insert the given data:
Pyramid's volume = 1/8 cubed feet
Pyramid's height = 0.5 feet
Base area = (3*1/8) / (1/2) / re-arrange the equation (*see solving tip)
=> Base area = (3*1/8)*(2/1) = (3/8)*(2/1) = (3*2) / (8*1) = (3*2) / 8 = 6/8 = 3/4 = 0.75
=> Base area = 0.75

Solving tip: When dividing one fraction by another fraction, it is the same as multiplying the first fraction by the inverse second fraction:

(a/b) / (c/d) = (a/b) * (d/c)
In this question, we applied it as follows:
(3*1/8) / (1/2) = (3/8) / (1/2) = (3/8) * (2/1) = (3*2) / (8*1)

A triangle with a base of 60 inches and a height of 15 inches is placed on a surface. If the triangle covers half of the surface, how much of it will be covered by another triangle, with a base of 50 inches and height of 12 inches?
A. 1.5.

B. 2/3.

C. 0.75.

D. 1/3.

E.  N.

Explanation

The correct answer is (D) - 1/3

The formula for calculating the area of a triangle is:
Area of a triangle = 1/2(base*height)

First, calculate the area of the first triangle:
Triangle's base = 60 inches
Triangle's height = 15 inches
Area of the first triangle = 1/2(60*15) = 1/2(60*10 + 60*5) = 1/2(600 + 300) = (1/2)*900 = 900/2 = 450 square inches

According to the question the first triangle whose area calculated above, covers half the surface. Therefore, 450 square inches is half the whole area's surface:
450 = (1/2)*whole area surface
Therefore, to find the whole area surface multiply both sides of the equation by 2:
2*450 = 2*(1/2)*whole area surface
The whole area surface = 900 square inches
To find how much of the whole surface's area will be covered by a triangle whose base = 50 inches and height = 12 inches, first, calculate this second triangle's area:
Area of the second triangle = 1/2(50*12) = 1/2(50*10 + 50*2) = 1/2(500 + 100) = (1/2)*600 = 600/2 = 300 square inches

Finally, calculate how much is the second triangle's area (300 square inches) from the whole surface's area (900 square inches):
300/900 = 3/9 = 1/3

The second triangle covers 1/3 of the surface.

The purpose of these questions is to evaluate your ability to solve geometric problems, based on the provided information. For more Calculating Areas and Perimeters questions, go to the following page.

### Deductive Reasoning

4. RULE

Child Abuse – The crime of child abuse is committed when:

Any recent act or failure to act on the part of a parent or caretaker which results in death of, serious physical or emotional harm to, sexual abuse of, or exploitation of their child; or
An act or failure to act on the part of a parent or caretaker which presents an imminent risk of serious harm to his or her child.

Which of the following best constitutes a case of child abuse?

A. Rachel's babysitter enjoys making Rachel cry by convincing her that her parents hate her.

B. Melllissa spanked Donny

Rachel's babysitter is "a […] caretaker" of Rachel's, and what she is doing clearly "results in [serious] emotional harm." Therefore, the scenario satisfies clause (a) of the definition of the crime. Since satisfying one clause suffices (notice the "or" between the clauses), Rachel's babysitter is committing child abuse.

Answer (B) is incorrect because Melissa is not causing "serious physical harm."

Answer (C) is incorrect because there is no "imminent risk" to Andrews's child.

Answer (D) is incorrect because Sean is neither a parent nor a caretaker of his younger brother.

### Inductive Reasoning

During which period in 2015 did both Arson incidents and Electrical Fire incidents have steadily decreased?

A. April-June.

B. March-May.

C. February-April.

D. January-March.

Explanation

Both the blue and red lines' slope decrease from February to March and from March to April, therefore, Arson and Electric Fire incidents are steadily decreasing from February to April.

Tip:
When you are asked about upward trends or downward trends of a line chart, there is no need to extract the numerical data from the chart, because we can infer the trends by looking at the slope.

Deductive Reasoning questions are designed to assess your ability to apply general rules to specific situations and come to logical conclusions. Inductive Reasoning questions will require you to identify a rule or concept which fits a given situation.

### Written Communication - Information Presentation

6. The following notes represent part of a working outline for a report for funding to launch a new Measles Vaccine campaign.

NOTES:

• Highly contagious.
• Measles cases have decreased by 99.9% in the US.
• Still endemic in places around the world.
• All Americans are encouraged to be vaccinated against measles.
• In 2013, 27 cases of measles were reported, the highest amount of cases in 20 years.
• Unvaccinated communities are at high risk if they interact with someone who has been exposed to measles.

QUESTION: Which one of the following choices most clearly and accurately expresses the facts presented in the notes?

A. There is a need for a new Measles Vaccine campaign because measles is highly contagious, and in 2013 more cases were reported than in the past 20 years.

B. Unvaccinated communities are at high risk of contracting measles because it is still endemic in the US.

C. In 2013, there were more cases reported than in the past 20 years. With measles being highly contagious, Americans need to be encouraged to be vaccinated, so they do not die from this deadly disease.

D. Responding to the spreading endemic of measles worldwide, Americans no longer need to be vaccinated, as someone who has been exposed is already immune to the disease.

Explanation
Answer A: Correct. The answer provided correct information that was in the notes. Measles is highly contagious and there were more cases reported in the past 20 years.

Answer B: This answer is incorrect because it provides false information, the notes states that measles are endemic in places around the world; it does not say it is endemic in the US.

Answer C: This answer is incorrect because it provides additional information that could be inferred, but was not stated in the notes. The notes do not state that people "will die from this deadly disease." When writing these reports you must stick to the facts: who, what and where.

Answer D: This answer is incorrect because it provides contradictory information for the purpose of the question. These are notes to launch a new Measles Vaccine campaign, so by saying "Americans no longer need to be vaccinated" contradicts the purpose of the report. In addition it provides information not in the notes, "as someone who has been exposed is already immune to the disease."

Information presentation questions are designed to assess your ability to choose the sentence that best expresses the ideas in the sentences provided.

Answer D is wrong because Eve Rd is one way.

### Understanding Information

12. Keeping safe in a shop
There have been significant fires in retail premises in displays of white spirit and similar products. The plastic containers readily melt in the fire, spilling their contents, fueling very rapid fire growth.

To minimize this risk, you need to ensure that the stock is kept to the minimum necessary for business needs, especially in areas to which the public have access. Storage areas should be carefully chosen, so that they are away from sources of ignition and heating in the building. This will also enable your staff to readily see any incidents, such as spillages and leaks.

Your staff should be trained in what do in an emergency and the necessary equipment and arrangements need to be put in place to enable them to do this safely.

Which of the following reasons mentioned in the article may lead to a fire developing?

A. Allowing your staff to smoke.

B. Having untrained staff.

C. Having a fire-proof suit.

D. Having dangerous chemicals near a source of ignition.

Explanation
The correct answer is (D), as dangerous chemicals are the only topic mentioned as possibly being a cause of fire.
