A construction crew has a spool containing exactly 14\frac{1}{4} mile of underground cable. They use 12023120 \frac{2}{3} yards of the cable for their first trench and 412412 feet 88 inches of the cable for their second trench. How much cable remains on the spool?

Show answer & explanation

Answer: 545 feet 4 inches

Answer

545 feet 4 inches
To find the remaining cable, all measurements must be converted to a common unit. First, find the total cable in feet: since 1 mile=5280 feet1 \text{ mile} = 5280 \text{ feet}, 14 mile=1320 feet\frac{1}{4} \text{ mile} = 1320 \text{ feet}. Next, convert the first trench length to feet: 12023 yards×3 feet/yard=362 feet120 \frac{2}{3} \text{ yards} \times 3 \text{ feet/yard} = 362 \text{ feet}. The second trench is 412 feet 8 inches412 \text{ feet } 8 \text{ inches}. The total used is 362 feet+412 feet 8 inches=774 feet 8 inches362 \text{ feet} + 412 \text{ feet } 8 \text{ inches} = 774 \text{ feet } 8 \text{ inches}. Finally, subtract this from the starting amount. Borrowing 1 foot1 \text{ foot} (12 inches12 \text{ inches}) from 1320 feet1320 \text{ feet} gives 1319 feet 12 inches1319 \text{ feet } 12 \text{ inches}. Subtracting the used cable gives 1319−774=545 feet1319 - 774 = 545 \text{ feet} and 12−8=4 inches12 - 8 = 4 \text{ inches}.

Step-by-Step Solution

1
Convert the total cable length from miles to feet.
14×5280=1320\frac{1}{4} \times 5280 = 1320 feet.
Standardizing all measurements to the same base unit (feet) is required before adding or subtracting.
2
Convert the length used for the first trench from yards to feet.
12023×3=362120 \frac{2}{3} \times 3 = 362 feet.
There are 3 feet in a yard, so multiplying the mixed fraction by 3 gives the exact length in feet.
3
Calculate the total amount of cable used for both trenches.
362 feet+412 feet 8 inches=774 feet 8 inches362 \text{ feet} + 412 \text{ feet } 8 \text{ inches} = 774 \text{ feet } 8 \text{ inches}.
Adding the individual segments provides the total length that must be subtracted from the spool.
4
Subtract the total used cable from the total spool length.
1320 feet−774 feet 8 inches=545 feet 4 inches1320 \text{ feet} - 774 \text{ feet } 8 \text{ inches} = 545 \text{ feet } 4 \text{ inches}.
To subtract the 8 inches, borrow 1 foot (12 inches) from 1320 feet to make it 1319 feet 12 inches. Subtracting yields 1319−774=5451319 - 774 = 545 feet and 12−8=412 - 8 = 4 inches.

Question 2Question →

A carpenter is preparing to install baseboards in a room. One specific section of the wall requires a continuous board that is exactly 22 yards and 22 feet long. What is the required length of this board in inches?

Show answer & explanation

Answer: 96

Answer

The required length of the board is 96 inches.
The correct total length is found by converting all measurements to the same unit. First, 2 yards is converted to 6 feet (2×3=62 \times 3 = 6). Adding the extra 2 feet gives a total of 8 feet. Finally, converting 8 feet to inches yields 96 inches (8×12=968 \times 12 = 96). Alternatively, you can convert both to inches directly: 2 yards = 72 inches, and 2 feet = 24 inches. Adding them together gives 72+24=9672 + 24 = 96 inches.

Step-by-Step Solution

1
Convert the yards measurement to feet.
2 yards = 6 feet.
It is easier to add measurements of the same unit (feet) before finding the final total in inches.
2
Calculate the total length in feet.
6 feet + 2 feet = 8 feet.
This combines both parts of the given measurement into a single unit.
3
Convert the total feet into inches.
8 feet * 12 inches/foot = 96 inches.
The question specifically asks for the final answer in inches, and there are 12 inches in every foot.

Question 3Question →

A surveyor is mapping four sections of a property perimeter, with measurements recorded in different US customary unit formats. Arrange these four sections in order from the shortest length to the longest length.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct order from shortest to longest is Section P (648 ft), Section Q (659 ft), Section R (660 ft), and Section S (661.5 ft).
To accurately compare these mixed measurements, each value must be mathematically converted to a single common unit, such as feet. Converting yields: Section P = 648 feet, Section Q = 659 feet, Section R = 660 feet, and Section S = 661.5 feet. Sorting these calculated totals produces the correct ascending sequence: Section P, Section Q, Section R, Section S.

Step-by-Step Solution

1
Convert the length of Section P to a standard unit (feet).
528528 feet + 120120 feet = 648648 feet.
110\frac{1}{10} mile ×5,280\times 5,280 ft/mile = 528528 ft. 4040 yards ×3\times 3 ft/yard = 120120 ft.
2
Convert the length of Section Q to feet.
657657 feet + 22 feet = 659659 feet.
219219 yards ×3\times 3 ft/yard = 657657 ft. 2424 inches ÷12\div 12 inches/ft = 22 ft.
3
Convert the length of Section R to feet.
660660 feet.
18\frac{1}{8} mile ×5,280\times 5,280 ft/mile = 660660 ft.
4
Convert the length of Section S to feet.
661.5661.5 feet.
7,9387,938 inches ÷12\div 12 inches/ft = 661.5661.5 ft.
5
Order the standardized lengths from shortest to longest.
648648 (P) < 659659 (Q) < 660660 (R) < 661.5661.5 (S).

Question 4Question →

A tailor is combining two pieces of fabric to make a continuous banner. One piece is 3123 \frac{1}{2} yards long, and the second piece is 1141 \frac{1}{4} yards long. After joining them together end-to-end, the tailor needs to cut the combined fabric into smaller segments that are each 1515 inches long. How many complete segments can the tailor cut from the combined fabric?

Show answer & explanation

Answer: 11

Answer

11
The total length of the fabric is found by adding 3123 \frac{1}{2} yards and 1141 \frac{1}{4} yards, which equals 4344 \frac{3}{4} yards. Because there are 3636 inches in one yard, this is equivalent to 4.75×36=1714.75 \times 36 = 171 inches. Dividing the total 171171 inches by the required segment length of 1515 inches gives 11.411.4. Therefore, 1111 complete segments can be cut.

Step-by-Step Solution

1
Calculate the total length of the fabric in yards.
312+114=324+114=434 yards3 \frac{1}{2} + 1 \frac{1}{4} = 3 \frac{2}{4} + 1 \frac{1}{4} = 4 \frac{3}{4} \text{ yards}
The two pieces are joined end-to-end, requiring addition with a common denominator.
2
Convert the total length from yards to inches.
434 yards×36 inches/yard=171 inches4 \frac{3}{4} \text{ yards} \times 36 \text{ inches/yard} = 171 \text{ inches}
The target segment length is in inches, so the total fabric length must share the same unit before dividing.
3
Divide the total inches by the length of one segment.
171÷15=11.4171 \div 15 = 11.4
Division determines how many 1515-inch segments fit into the 171171-inch length.
4
Identify the number of complete segments.
1111
The tailor can only use whole, complete segments, so the decimal remainder is dropped.

Show answer & explanation

Answer

The correct order from shortest to longest is: 50 inches, 4 feet 6 inches, 5 feet, and 2 yards.
By converting all measurements to inches, we can clearly see the relative lengths: 50 inches is the shortest, followed by 4 feet 6 inches (which is 54 inches), then 5 feet (which is 60 inches), and finally 2 yards (which is 72 inches) as the longest.

Step-by-Step Solution

1
Identify the goal: convert all measurements to a single common unit to make comparison easy.
The target unit chosen is inches.
Comparing different units directly without conversion leads to errors.
2
Evaluate the first length: 50 inches.
50 inches remains 50 inches.
It is already in the target unit.
3
Convert the second length: 4 feet 6 inches into inches.
4×12=484 \times 12 = 48 inches. Adding the extra 6 inches gives 48+6=5448 + 6 = 54 inches.
There are 12 inches in 1 foot.
4
Convert the third length: 5 feet into inches.
5×12=605 \times 12 = 60 inches.
There are 12 inches in 1 foot.
5
Convert the fourth length: 2 yards into inches.
2×36=722 \times 36 = 72 inches.
There are 36 inches in 1 yard (or 3 feet per yard, and 12 inches per foot: 2×3×12=722 \times 3 \times 12 = 72).
6
Order the converted values from shortest to longest.
50 inches < 54 inches < 60 inches < 72 inches.
This confirms the final proper sequence of the wire pieces.

A landscaper places two lengths of wooden garden edging end-to-end to border a flower bed. The first piece is 7127 \frac{1}{2} feet long, and the second piece is 4124 \frac{1}{2} feet long. What is the total length of the edging in inches?

Show answer & explanation

Answer: 144

Answer

144
First, the two fractional lengths must be combined: 7127 \frac{1}{2} plus 4124 \frac{1}{2} equals exactly 12 feet. Since there are 12 inches in a single foot, the total measurement in inches is found by multiplying the 12 feet by 12. This yields a final answer of 144 inches.

Step-by-Step Solution

1
Add the lengths of the two pieces of edging together in feet.
712+412=127 \frac{1}{2} + 4 \frac{1}{2} = 12 feet
Finding the total combined length is the first step before converting to the requested unit.
2
Convert the total length from feet to inches.
12×12=14412 \times 12 = 144 inches
There are 12 inches in 1 foot, so multiplying the number of feet by 12 gives the length in inches.

Question 8Question →

An HVAC technician is installing a straight run of ventilation ductwork that must be exactly 44 yards and 22 feet long. The ducting material comes in standard pre-cut sections that are exactly 2020 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 11 yard equals 33 feet, 44 yards is 1212 feet. Adding the extra 22 feet gives a total of 1414 feet. Because 11 foot equals 1212 inches, 1414 feet is 168168 inches. Each standard duct section is 2020 inches long. Dividing 168168 by 2020 gives 88 with a remainder of 88 (or 8.48.4), meaning 88 full sections provide only 160160 inches, which is not enough. A 9th9^{\text{th}} section is needed. The total length of 99 uncut sections is 180180 inches. To find the amount discarded, subtract the required length from the total material length: 180−168=12180 - 168 = 12 inches.

Step-by-Step Solution

1
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.
2
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.
3
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.
4
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.

A stage crew is connecting two sections of metal piping end-to-end to build a vertical pole for a lighting rig. The bottom section is 2122 \frac{1}{2} yards long. The top section is 44 feet 66 inches long. What is the total height of the assembled pole in yards?

Show answer & explanation

Answer: 44

Answer

The total height of the assembled pole is 44 yards.
To find the total height, both measurements must be converted to the same unit. The top section is 44 feet 66 inches, which is exactly 4.54.5 feet. Since there are 33 feet in a yard, dividing 4.54.5 by 33 yields 1.51.5 yards (or 1121 \frac{1}{2} yards). Adding this to the bottom section's length of 2122 \frac{1}{2} yards gives exactly 44 yards.

Step-by-Step Solution

1
Convert the length of the top section from feet and inches to a single unit (feet).
44 feet 66 inches equals 4.54.5 feet (since 66 inches is half of a foot).
It is necessary to express the length in a uniform unit before converting it to yards.
2
Convert the top section's length from feet to yards.
4.54.5 feet divided by 33 feet per yard equals 1.51.5 yards (or 1121 \frac{1}{2} yards).
The final requested answer is in yards, so both sections must be expressed in this unit.
3
Add the lengths of both sections in yards.
212 yards+112 yards=4 yards2 \frac{1}{2} \text{ yards} + 1 \frac{1}{2} \text{ yards} = 4 \text{ yards}.

Question 12Question →

A metal fabricator starts with a single steel rod that measures exactly 44 yards and 22 feet in length. From this rod, they cut 77 identical segments, each measuring exactly 11 foot and 55 inches long. Assuming no material is lost during the cutting process, how many inches of the steel rod remain?

Show answer & explanation

Answer: 49

Answer

49 inches
The correct answer is found by converting all lengths into inches (44 yards =144= 144 in, 22 feet =24= 24 in, Total =168= 168 in), finding the total length of the cut pieces (7×177 \times 17 in =119= 119 in), and subtracting the cuts from the total (168−119=49168 - 119 = 49 inches).

Step-by-Step Solution

1
Convert the total initial length of the steel rod into inches.
44 yards =144= 144 inches; 22 feet =24= 24 inches. Total =168= 168 inches.
Converting to the smallest unit (inches) at the beginning prevents errors when subtracting later.
2
Convert the length of a single cut segment into inches.
11 foot =12= 12 inches; 12+5=1712 + 5 = 17 inches per segment.
The length of each cut segment must be in the same base unit as the total rod.
3
Calculate the total length of steel used for all 77 segments.
7×177 \times 17 inches =119= 119 inches.
This determines the total amount of material that will be removed from the original rod.
4
Subtract the total used length from the initial rod length.
168168 inches −119- 119 inches =49= 49 inches.
Subtracting the removed material from the starting material gives the final remaining length.

Subtract the lengths of the first two segments from the total trail length to find the boardwalk length.
18,480−(6,600+4,500)=18,480−11,100=7,38018,480 - (6,600 + 4,500) = 18,480 - 11,100 = 7,380 feet
The trail consists of three contiguous parts, so removing the known parts from the whole leaves the unknown final part.

A communications technician is preparing four different runs of fiber optic cable for an office building installation. To organize the work, the technician must sort the cable runs from shortest to longest.

Run 1: 115115 yards and 22 feet
Run 2: 4,1884,188 inches
Run 3: 115\frac{1}{15} of a mile
Run 4: 350350 feet and 66 inches

Arrange the cable runs in order from shortest to longest.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct order from shortest to longest is: Run 1, Run 2, Run 4, and Run 3.
By converting all lengths to a common unit (feet), we can directly compare them. Run 1 is 347347 feet, Run 2 is 349349 feet, Run 4 is 350.5350.5 feet, and Run 3 is 352352 feet. Ordering these from smallest to largest yields the correct sequence: Run 1, Run 2, Run 4, Run 3.

Step-by-Step Solution

1
Convert the length of Run 1 into feet.
347347 feet
Since 11 yard equals 33 feet, multiply 115115 yards by 33 to get 345345 feet. Add the additional 22 feet for a total of 347347 feet.
2
Convert the length of Run 2 into feet.
349349 feet
Since 11 foot equals 1212 inches, divide 4,1884,188 inches by 1212 to get 349349 feet.
3
Convert the length of Run 3 into feet.
352352 feet
Since 11 mile equals 5,2805,280 feet, divide 5,2805,280 by 1515 (or multiply by 115\frac{1}{15}) to get 352352 feet.
4
Convert the length of Run 4 into feet.
350.5350.5 feet
Since 66 inches is exactly 12\frac{1}{2} of a foot, the measurement is 350.5350.5 feet.
5
Compare the standardized lengths and order them from shortest to longest.
Run 1 (347347 ft) < Run 2 (349349 ft) < Run 4 (350.5350.5 ft) < Run 3 (352352 ft)
Comparing all measurements in a common unit (feet) reveals the final correct sequence.

Question 15Question →

An awning installer is measuring canvas fabric for two separate storefronts. The first storefront requires a continuous fabric length of 1341 \frac{3}{4} yards. The second storefront requires a length of 2122 \frac{1}{2} yards. What is the total length of canvas required for both storefronts, expressed in feet and inches?

Show answer & explanation

Answer: 1212 feet 99 inches

Answer

1212 feet 99 inches
The correct answer is derived by first successfully adding the two mixed fractions (134+2121 \frac{3}{4} + 2 \frac{1}{2}) to find a total of 4144 \frac{1}{4} yards. Converting this length to feet requires multiplying by 33, yielding 123412 \frac{3}{4} feet. Finally, the remaining 34\frac{3}{4} of a foot is converted to inches by multiplying by 1212, resulting in exactly 1212 feet and 99 inches.

Step-by-Step Solution

1
Add the two yardage amounts together by finding a common denominator.
134+224=354=4141 \frac{3}{4} + 2 \frac{2}{4} = 3 \frac{5}{4} = 4 \frac{1}{4} yards.
To find the total amount of canvas needed, the fractional values must be combined correctly.
2
Convert the total yards into feet by multiplying by 3.
414×3=174×3=514=12344 \frac{1}{4} \times 3 = \frac{17}{4} \times 3 = \frac{51}{4} = 12 \frac{3}{4} feet.
Because there are 3 feet in 1 yard, multiplying the yardage by 3 gives the equivalent measurement in feet.
3
Convert the fractional portion of the foot into inches by multiplying by 12.
34×12=364=9\frac{3}{4} \times 12 = \frac{36}{4} = 9 inches. The final combined measurement is 1212 feet 99 inches.
Standard linear measurements require any fraction of a foot to be expressed in inches (12 inches = 1 foot).
