Question 3861Question →

The inspector noticed that the contractor had miscalculated the total weight of the cargo. In this sentence, what does the word miscalculated mean?

Estimated far in advance

Calculated incorrectly

Determined with exact precision

Combined multiple calculations

Show answer & explanation

Answer: Calculated incorrectly

Answer

Calculated incorrectly

The correct definition is 'Calculated incorrectly' because the common prefix 'mis-' attaches to verbs and nouns to signify wrongness or error. Combining 'mis-' with 'calculated' yields the meaning of making an arithmetic or judgment error.

Step-by-Step Solution

Isolate the prefix and the base word in 'miscalculated'

The prefix is 'mis-' and the base word is 'calculated'

Breaking the word into its morphological components helps reveal its structural meaning.

Apply the meaning of the common prefix 'mis-' to the base word

'mis-' means wrongly, badly, or mistakenly; therefore, 'miscalculated' means calculated wrongly or incorrectly

Prefixes modify the root word's core definition in predictable ways.

Key Concept

The prefix 'mis-' conveys the meaning of wrongly, badly, or mistakenly when attached to a base word.

Question 3863Question →

A maintenance crew purchases $8$ gallons of epoxy paint for a warehouse floor. They need to pour the paint into smaller trays that each hold exactly $2$ quarts. How many trays can they fill completely?

Show answer & explanation

Answer: 16

Answer

16 trays

First, find the total number of quarts available. Because there are 4 quarts in 1 gallon, 8 gallons is equal to 32 quarts. Next, divide the 32 total quarts by the 2-quart capacity of each tray. This yields exactly 16 filled trays.

Step-by-Step Solution

Convert the total paint volume from gallons to quarts.

32 quarts

The trays are measured in quarts, so the total paint volume must be converted to the same unit. (8 gallons × 4 quarts/gallon = 32 quarts)

Divide the total number of quarts by the capacity of a single tray.

16 trays

This determines how many 2-quart portions can be distributed from the 32 quarts of paint. (32 quarts ÷ 2 quarts/tray = 16 trays)

Key Concept

Converting between standard US customary volume units (gallons to quarts) and dividing by a unit capacity.

Question 3864Question →

An HVAC technician is installing a straight run of ventilation ductwork that must be exactly $4$ yards and $2$ feet long. The ducting material comes in standard pre-cut sections that are exactly $20$ inches long. The technician connects these sections end-to-end. Once the connected sections exceed the required length, the excess material is cut off from the final section so the ductwork matches the exact required length. How many inches of material will be cut off and discarded from the final section?

Show answer & explanation

Answer: 12

Answer

12 inches

First, convert the total required length into inches. Since

1

yard equals

3

feet,

4

yards is

12

feet. Adding the extra

2

feet gives a total of

14

feet. Because

1

foot equals

12

inches,

14

feet is

168

inches. Each standard duct section is

20

inches long. Dividing

168

20

gives

8

with a remainder of

8

(or

8.4

), meaning

8

full sections provide only

160

inches, which is not enough. A

9^{\text{th}}

section is needed. The total length of

9

uncut sections is

180

inches. To find the amount discarded, subtract the required length from the total material length:

180 - 168 = 12

inches.

Step-by-Step Solution

Convert the required measurement from yards and feet into a single unit of inches.

168 inches

Standardizing the units makes it possible to compare the required length directly with the 20-inch section length.

Determine the number of 20-inch sections needed by dividing the total required length by the length of one section.

8.4 sections, which rounds up to 9 sections.

The technician must use whole sections and cut the final one, so we must round up to the next whole number.

Calculate the total length of the 9 full sections before any cutting.

180 inches

This represents the total raw material used before the final piece is trimmed to fit.

Subtract the exact required length from the total raw material length.

12 inches

The difference between the total material length and the required length is the excess that must be cut off and discarded.

Question 3865Question →

Rather than writing the glowing letter of support the student had requested, the academic advisor submitted a qualified endorsement that frankly outlined the applicant's struggles with independent laboratory research.

Which of the following choices best expresses the meaning of the underlined word in this specific context?

Conditional

Competent

Unreserved

Derogatory

Show answer & explanation

Answer: Conditional

Answer

Conditional

The sentence contrasts the 'glowing letter' the student wanted with the actual endorsement given, which frankly outlined the student's 'struggles'. In this context, 'qualified' does not mean certified or competent; rather, it means limited, restricted, or modified by specific reservations. Therefore, 'Conditional' is the exact synonym.

Step-by-Step Solution

Analyze the contrast established in the first half of the sentence.

The phrase 'Rather than writing the glowing letter' indicates that the advisor's actual endorsement was NOT fully supportive.

Contrast clues like 'Rather than' signal that the target word will represent a departure from the preceding idea.

Evaluate the specific details provided about the endorsement.

The endorsement 'frankly outlined the applicant's struggles', meaning it contained reservations, critiques, or restrictions.

These contextual details define the exact tonal nature of the advisor's response.

Select the option that matches a restricted or reserved statement.

The word 'Conditional' perfectly captures a statement made with restrictions or reservations.

In advanced vocabulary contexts, 'qualified' means limited or modified in some way, making 'Conditional' the correct synonym.

Question 3867Question →

A cylindrical farm silo is built to store corn. The interior of the silo has a radius of $7\text{ feet}$ and a height of $20\text{ feet}$ . Using $\frac{22}{7}$ for $\pi$ , what is the total volume of the silo in cubic feet?

Show answer & explanation

Answer: 3080

Answer

The total volume of the silo is 3080 cubic feet.

The correct answer is calculated by applying the volume formula for a cylinder,

V = \pi r^2 h

. Substituting

7

for the radius and

20

for the height, along with

\frac{22}{7}

for

\pi

, results in

3080\text{ cubic feet}

Step-by-Step Solution

Recall the volume formula

V = \pi r^2 h

This is the standard formula required to find the volume of any cylinder.

Substitute the given values

V = \frac{22}{7} \times (7)^2 \times 20

We plug in

r = 7

h = 20

, and

\pi = \frac{22}{7}

as provided in the question.

Square the radius

V = \frac{22}{7} \times 49 \times 20

Following the order of operations, exponents must be calculated before multiplication.

Multiply and simplify

V = 22 \times 7 \times 20 = 3080

Simplifying the fraction

\frac{22}{7} \times 49

leaves

22 \times 7 = 154

. Multiplying

Question 3877Question →

A machinist is fabricating a circular metal part with a diameter of $12$ inches. To allow for bolts, four identical circular holes, each with a radius of $2$ inches, are cut out of the part. What is the area of the remaining metal in square inches? (Use $\pi = 3.14$ )

Show answer & explanation

Answer: 62.8

Answer

62.8

The remaining area is found by subtracting the total area of the four smaller circular holes from the area of the large circular part. The large part has a radius of 6 inches (half of the 12-inch diameter), giving an area of 113.04 square inches. Each of the four holes has a radius of 2 inches, yielding an area of 12.56 square inches per hole, or 50.24 square inches total. Subtracting 50.24 from 113.04 leaves 62.8 square inches.

Step-by-Step Solution

Find the radius of the large circular part.

Radius = 12 / 2 = 6 inches.

The area formula for a circle requires the radius, but the diameter was given.

Calculate the total area of the large circular part.

Area = 3.14 * 6^2 = 113.04 square inches.

This represents the total amount of metal before any holes are cut.

Calculate the area of one small bolt hole.

Area = 3.14 * 2^2 = 12.56 square inches.

Each hole is a smaller circle removed from the part.

Find the total area of all four bolt holes.

Total hole area = 12.56 * 4 = 50.24 square inches.

There are four identical holes that need to be accounted for.

Subtract the total hole area from the large part's area.

Remaining area = 113.04 - 50.24 = 62.8 square inches.

Subtracting the removed material gives the final remaining area of the metal part.

an outdated or antiquated viewpoint

a strong feeling of intense dislike or hostility

a state of total indifference or emotional numbness

a deep sense of affection and mutual understanding

Show answer & explanation

Answer: a strong feeling of intense dislike or hostility

Answer

a strong feeling of intense dislike or hostility

The word 'antipathy' derives from the Greek prefix 'anti-' (against) and root 'pathos' (feeling), denoting a settled aversion, hostility, or intense dislike.

Step-by-Step Solution

Analyze the morphological structure of the target word 'antipathy'

The word breaks down into the Greek prefix 'anti-' (meaning 'against' or 'opposite') and the Greek base morpheme 'pathos' / '-pathy' (meaning 'feeling', 'emotion', or 'suffering').

Etymological segmentation reveals the foundational meaning of the compound word.

Synthesize the morphemes and evaluate the contextual clues

Combining 'against' and 'feeling' yields 'a feeling against' or strong aversion. The context of delegates harboring persistent tension despite years of working together reinforces a state of mutual hostility.

Morphological analysis combined with context confirms that 'antipathy' means deep-seated hatred, aversion, or hostility.
