Gary eats 2 hamburgers a day. If each hamburger weighs 6 ounces, how many pounds of hamburger does Gary eat per week?

  • 5 pounds, 4 ounces

  • 84 pounds

  • 4 pounds, 5 ounces

  • 5 pounds, 2 ounces

  • 3 pounds, 12 ounces

Correct answer: 5 pounds, 4 ounces

First, calculate the total number of ounces of hamburger that Gary consumes per week. Each day, he eats 12 ounces of hamburger (2 * 6). Multiply 12 by 7 to get his weekly total of 84 ounces.

Now, convert ounces to pounds. There are 16 ounces to 1 pound. 84 divided by 16 is 5, with a remainder of 4.

The reader wants to know what the definition of eclipse is. Where can the reader look to determine the definition the quickest?

  • Glossary

  • Index

  • Appendix

  • Bibliography

  • 7 - Eclipses

Correct answer: Glossary

The glossary of a textbook is where you can find a list of difficult or specialized words with their definitions; thus, the glossary would be the quickest method to determine what the definition of eclipse is.

143.

All of the following are examples of secondary sources except:

  • Manuscripts

  • Encyclopedias

  • Dissertations

  • Textbooks

  • A book of photographs from a historical era

Correct answer: Manuscripts

Manuscripts are examples of primary sources, which are documents that were created during the time under study. They may be able to offer insight or an inside view into a particular time or event.

The remaining answer options are incorrect because they are examples of secondary sources, which are sources that compile, analyze, or comment on primary sources. Encyclopedias, dissertations, and textbooks are all examples of secondary sources. Though the original photographs from a historical era would be considered primary sources, a book of those same photographs is considered to be a secondary source.

144.

If the value of y is between -0.60 and 0.01, which of the following could be the value of y?

  • -0.1

  • -0.75

  • 0.11

  • -0.65

  • 0.21

Correct answer: -0.1

-0.10 is between -0.60 and 0.01. -0.75 and -0.65 are smaller than -0.60, and 0.11 and 0.21 are greater than 0.01.

145.

What percentage of the number of people represented in the graph own dogs?

  • 23.5%

  • 8.0%

  • 28.5%

  • 33.9%

  • 25.0%

Correct answer: 23.5%

1. Determine the total number of people represented.

4 + 8 + 11 + 6 + 5 = 34

2. Determine the number of dog owners in proportion to the total number of people.

Dog owners = 8 people

8/34 = fraction of people who own dogs

3. Divide to find the percentage.

8/34 = 23.5%

Select the underlined portion that must be revised to produce a correct sentence.

Charlotte and Amanda decided that the best course of action would to immediately call their parents.

  • Would to

  • Decided that

  • Best course of action

  • Their

  • No error

Correct answer: Would to

In this sentence, the word "be" is required after "would." The correct version of the sentence reads, "Charlotte and Amanda decided that the best course of action would be to immediately call their parents." 

The remaining answer options are correct and do not need to be changed.

147.

The sentence below contains four portions that are identified with quotation marks. Read the sentence and determine which portion contains an error in diction, usage, idiom, or grammar.

Neither the wife “or” the husband “remembered” “that” yesterday “was” their wedding anniversary.

  • Or

  • Remembered

  • That

  • Was

  • No error

Correct answer: Or

This sentence contains an error with the correlative conjunction “Neither … or.” When “neither” is used in the sentence, it should be paired with “nor,” not “or.”

The verbs in the sentence are written in the correct tense, and the use of the pronoun “that” is idiomatically correct.

148.

Karen sells hamburgers for $2.50 and hot dogs for $1.00. In the month of July, Karen sold 300 hamburgers and 300 hot dogs. Karen uses the following expression to calculate July's revenue:

($2.50 * 300) + ($1.00 * 300)

Which of the following expressions could Karen have also used?

  • 300 * ($2.50 + $1.00)

  • (600 * $2.50) + $1.00

  • 600 * $3.50

  • (300 + 300) * ($2.50 + $1.00)

  • 600 / ($2.50 + $1.00)

Correct answer: 300 * ($2.50 + $1.00)

If you solve the expression given to you, you have $750.00 + $300.00 = $1,050.00. Therefore, the correct answer needs to produce a value of $1,050.00.

The expression 300 * ($2.50 + $1.00) = $1,050.00. This yields the same value as the given expression, so it is the correct answer.

149.

x * x * x * x * x = ?

  • x5

  • 5x

  • x/5

  • 0

  • 2x

Correct answer: x5

Any time a variable is multiplied by itself, the variable remains the same but the exponent represents how many times a variable is a factor. Since x is multiplied by itself 5 times, the answer is x5.

Using the table of data, place the following students' scores in order, from highest to lowest.

  • Holly, Blaine, Clay, Ashton

  • Blaine, Clay, Ashton, Holly

  • Clay, Ashton, Holly, Blaine

  • Ashton, Holly, Blaine, Clay

Correct answer: Holly, Blaine, Clay, Ashton

From the second column, you can rank three students based upon the information given: Holly, Blaine, and Clay. Ashton's percentile is not given, but because he had more incorrect answers (8) than Clay (7), his score must be lower than Blaine's.

View the supporting details to answer the following question.

Which vehicle saw the largest percent increase in sales from 2008 to 2009?

  • Sport Coupe

  • SUV

  • Truck

  • Crossover

Correct answer: Sport Coupe

Calculate the percent increase using the percent change formula (difference / original). The total for the Sport Coupe in 2008 is 500 and 550 in 2009.

The percent change fraction is 50/500, thus giving you the largest percent increase at 10.0%.

152.

Lori was having a bake sale. She was selling chocolate chip cookies for $0.50, peanut butter cookies for $0.75, and banana bread for $1.25. If Lori sold 15 chocolate chip cookies, 20 peanut butter cookies, and 5 banana breads, how much money did she make?

  • $28.75

  • $28.00

  • $40.00

  • $18.50

  • $22.50

Correct answer: $28.75

In order to find the amount of money that Lori made, you will need to multiply the number sold of each kind of item by that item's individual price.

Next, add those figures to obtain a total:

15($0.50) + 20($0.75) + 5($1.25) = $28.75

153.

Read the passage, then answer the following question.

Which of the following best describes the main point of the passage?

  • Hepatitis C is a deadly virus that baby boomers should be tested for

  • Hepatitis C is the leading cause of liver transplants

  • Americans born between 1945 and 1965 are known as baby boomers

  • Baby boomers are at risk for Hepatitis C because they shared intravenous needles

  • Hepatitis C kills 15,000 Americans each year

Correct answer: Hepatitis C is a deadly virus that baby boomers should be tested for

In the passage, the author discusses the effects and how individuals could have been infected with Hepatitis C, but states the importance of baby boomers being tested for the virus.

The first sentence and last sentence of the passage provides the answer: "According to recent studies, baby boomers should be tested for the hepatitis C virus...The study indicates that routine blood tests will address the largely preventable consequences of the disease."

154.

At a certain high school, 7 out of every 10 students will end up going to college. If there are 310 students, how many are expected to go to college?

  • 217

  • 70

  • 31

  • 210

  • 163

Correct answer: 217

This is a proportion question. You are given the relationship: 7 students go to college / 10 total students.

If you set this to equal your unknown relationship, you will have the following equation: 7 students go to college / 10 total students = x students go to college / 310 students.

If you cross multiply, you get 10x = 2,170.

x = 217

155.

Read the passage, then answer the following question.

This passage would most likely appear in:

  • A magazine article

  • An editorial

  • A doctoral thesis

  • A technology journal

  • A computer science textbook

Correct answer: A magazine article

The information is not too complex; therefore, a doctoral thesis, a technology journal, and a computer science textbook should be eliminated. Very little opinion is stated, if any, so eliminate an editorial. 

Since the information is described as recent, it would most likely appear in a magazine article.

156.

Choose the option that best expresses the intended meaning of the quoted portion of the original sentence; this answer should use proper grammar, diction, sentence construction, and punctuation.

During the hurricane, volunteers placed sandbags along the “river, and they thereby blocked it from flooding the roads.”

  • River, thereby blocking it from flooding the roads.

  • River, and they thereby blocked it from flooding the roads.

  • River, by which all water was therefore blocked from the roads.

  • River and therefore blocking the roads from all the flood water.

  • River, and by which all flood water was now blocked from the roads.

Correct answer: River, thereby blocking it from flooding the roads.

The error with the original sentence is wordiness. The option “river, thereby blocking it from flooding the roads” is the shortest and clearest option. 

The conjunction “thereby” is more precise than “therefore” when being used to refer to an event.

157.

If the value of x is between 0.082 and 0.108, which of the following could be the value of x?

  • 0.095

  • 0.109

  • 0.117

  • 0.210

  • 0.079

Correct answer: 0.095

First, eliminate any answer choice that is not greater than 0.082. This will eliminate answer choice 0.079.

Next, eliminate any choice that is not less than 0.108. This will eliminate answer choices 0.109, 0.117, and 0.210.

The remaining answer choice, 0.095, is the correct answer.

158.

Read the passage, then answer the following question.

Which of the following sentences represents an opinion of the author rather than a fact?

  • 12

  • 2

  • 5

  • 6

  • 10

Correct answer: 12

The statement “one that we should all give a try” represents the feelings of the author, and would be difficult to prove. 

All other statements are facts.

159.
