What is Barb’s main argument in the provided communication?

  • Hannah should hire Dan

  • Dan is an excellent employee

  • Barb would like to promote Dan

  • Barb has no open positions in her department

Correct answer: Hannah should hire Dan

The author’s main argument is that Hannah should hire Dan, as stated in the following sentence: “While I do not wish to lose Dan, I will tell you that he is an excellent employee and you would be lucky to have him.” An argument is a set of reasons to make a case and it also represents the main purpose of the letter.

“Dan is an excellent employee” and “Barb would like to promote Dan” are statements used to support Barb’s argument. “Barb has no open positions in her department” is a claim that indirectly supports the main argument.

Convert 0.023 to a fraction.

  • 23/1,000

  • 23/100

  • 23/10

  • 23/100,000

Correct answer: 23/1,000

To convert a decimal into a fraction, there are a few considerations: a value greater than 1 and a value less than 1. In this case, 0.023 is less than 1.

Value less than 1

If a decimal value is less than one (0.023), simply use 23 as the numerator and the place value of the last decimal digit as the denominator (in this case thousandths). The decimal 0.023 would be written as 23/1,000.

Value more than 1

If the decimal value is more than one (for example, 2.36), move the decimal to the right until you have a whole number (in this case, 236). Keep track of how many decimal places you moved the decimal (two places). This whole number becomes the numerator. Then, your denominator becomes a 1 followed by the number of zeros that matches the number of places the decimal moved (100). The fraction representation of 2.36 is 236/100.

Write the following expression in words:

2x² - 3 = x + 12

  • Three less than twice the square of a number is twelve more than the number

  • Twice the square of a number is twelve more than the number

  • Twice the square of a number less than three is twelve more than the number

  • Three less than twice a number is twelve more than the number

Correct answer: 3 less than twice the square of a number is twelve more than the number

Start with the left side of the equation.

x² can be written as 'the square of a number.'

2x² can be written as 'twice the square of a number.'

2x² - 3 can be written as 'three less than twice the square of a number.'

Next, write out the right side of the equation.

x + 12 is written as 'twelve more than a number.

Therefore, the entire equation can be written as 'Three less than twice the square of a number is twelve more than the number.'

4 1/16 ÷ 3 1/8

Which of the following options correctly simplifies the above expression?

  • 1 3/10

  • 1 3/4

  • 1 1/4

  • 1 2/3

Correct answer: 1 3/10 

In order to simplify the expression, convert the mixed numbers to improper fractions.

4 1/16 = 65/16

3 1/8 = 25/8

In order to divide by a fraction, multiply it by its reciprocal.

65/16 ÷ 25/8 = 65/16 × 8/25

(65 × 8)/(16 × 25) = 520/400.

Reduce the fraction to its lowest terms.

520/400 ÷ 40/40 = 13/10

Convert the improper fraction to a mixed number.

13/10 = 1 3/10

150.

What might the organelles of a prokaryotic organism be compared to in a larger, more complex organism?

  • Organs

  • Nucleoid

  • Plasmids

  • Ribosomes

Correct answer: Organs

Organelles are features inside prokaryotic cells that serve functions similar to those of the organs of more complex creatures.

The nucleoid contains the cell's genes and genetic blueprint. Plasmids are tiny circular bits of DNA not associated with the nucleoid, and ribosomes use RNA messages to manufacture proteins for the cell.

The furniture in the dollhouse was designed on a 1:30 scale of the original furniture. If an original bed measured 5 feet by 8 feet, what are the measurements of the bed in the dollhouse?

  • 2 inches × 3.2 inches 

  • 5 inches × 8 inches 

  • 2.5 inches × 4 inches 

  • 15 inches × 24 inches 

Correct answer: 2 inches × 3.2 inches 

This question can be solved by setting it up as a proportion. First, convert the feet into inches.

1 foot = 12 inches

5 feet = 1 foot x 5 = 60 inches

8 feet = 1 foot x 8 = 96 inches

Then, solve each of the following proportions: 1/30 = x/60 and 1/30 = x/96.

1/30 = x/60

30x = 60

x = 2 inches

1/30 = x/96

30x = 96

x = 3.2 inches

Therefore, the dollhouse bed will measure 2” × 3.2”.

152.

Subtract 4/5 from 1/2.

  • -3/10

  • -2/5

  • 3/10

  • 3/5

Correct answer: -3/10

First convert the fractions to have common denominators.

1/2(5/5) - 4/5(2/2) = 5/10 - 8/10

Subtract.

5/10 - 8/10 = -3/10

153.

If hydrogen is in a compound, what would its oxidation number be?

  • +1

  • -2

  • -1

  • 0

Correct answer: +1

If hydrogen is in a compound, its oxidation number would be +1.

If oxygen is in a compound, its oxidation number would be -2. The oxidation number of an elemental atom is 0.

154.

A model car was designed on a 1:20 scale of the original car. If the original car had a length of 9 feet and a height of 4 feet, what are the measurements of the model car?

  • 5.4 inches × 2.4 inches

  • 4.5 inches × 2 inches

  • 18 inches × 8 inches

  • 9.2 inches × 4.2 inches

Correct answer: 5.4 inches × 2.4 inches

This question can be solved by setting it up as a proportion. First, convert the feet into inches:

1 foot = 12 inches

9 feet = 9 feet × 12 inches = 108 inches

4 feet = 4 feet × 12 inches = 48 inches

Then, solve each of the following proportions:

1/20 = x/108

  • 1/20 = x/108
  • 20x = 108
  • x = 5.4 inches

1/20 = x/48

  • 1/20 = x/48
  • 20x = 48
  • x = 2.4 inches

Therefore, the dimensions of the model car are 5.4 inches × 2.4 inches

Using context clues, what is the meaning of the word "cascaded" in this passage?

  • Plummeted

  • Trickled

  • Roared

  • Smoothed

Correct answer: Plummeted

The word cascaded means to plummet or fall quickly. Context clues such as "flowed heavily" and "waterfall" can help the reader determine the meaning of the word.

Trickled, roared, and smoothed are not words that describe how "cascaded" is used in the given text.

156.

To which body system does the colon belong?

  • Gastrointestinal system

  • Endocrine system

  • Neuromuscular system

  • Cardiovascular system

Correct answer: Gastrointestinal system

The gastrointestinal (digestive) system is responsible for breaking down food for absorption and distribution to the rest of the body. The gastrointestinal system begins at the mouth and ends at the anus. This system includes the stomach, small intestine, large intestine, liver, gallbladder, pancreas, colon, mouth, anus, and rectum.

In the final stage of the digestion process, waste from the small intestine is met with bacterial fermentation in the colon. This waste accumulates in the rectum and is ejected through the anus.

(2×2+1)/2 ÷ 1/2

2. Simplify 2×2 to 4

(4+1)/2 ÷ 1/2

3. Simplify 4+1 to 5

5/2 ÷ 1/2

What would a 15-kg object’s applied impulse be if it was moving at a speed of 10 m/s when its velocity changed to 20 m/s due to an impulse that was acted on it?

  • 150 kg*m/s

  • 200 kg*m/s

  • 300 kg*m/s

  • 100 kg*m/s

Correct answer: 150 kg*m/s

To find the impulse, or change in momentum, you will need to use the following equation:

The change in momentum = the object’s mass x the change in velocity.

Thus, 15 kg × (20 m/s – 10 m/s) = 150 kg*m/s.

Which of following options best represents the opinion of the author?

  • The football team should have won

  • The football team was beaten fairly

  • The game last week was close

A couple tipped their waitress 18% of their $62.43 check. What amount did the waitress receive as a tip?

  • $11.24

  • $9.36

  • $12.49

  • $10.61

Correct answer: $11.24

In order to solve this problem, convert 18% to a decimal.

18% = 18/100 = 0.18

Multiply the check total by the percentage and round to the nearest penny.

$62.43 × 0.18 = $11.2374 = $11.24
