A specialized water purification system takes $3$ hours and $20$ minutes to process one complete cycle. If an engineering detachment runs the system continuously for exactly $2.5$ days, how many complete cycles will the system finish?

Cevabı ve açıklamayı göster

Cevap: 18

Cevap

18

The correct answer is found by establishing a common unit of time (minutes) for both the total duration and the cycle length. First, converting the

2.5

days of total operation into hours gives

60

hours, which equals

3600

minutes. Next, converting the

3

hour and

20

minute cycle duration into minutes yields

200

minutes. Finally, dividing the total available time (

3600

minutes) by the cycle time (

200

minutes) results in exactly

18

complete cycles.

Cevap: 20

Cevap

20

To convert a weight from pounds to kilograms given that 1 kilogram equals 2.2 pounds, you must divide the total pounds by 2.2. Setting up the equation: 44 / 2.2 yields exactly 20. Thus, the shipment weighs 20 kilograms.

Adım Adım Çözüm

1

Identify the given value and the unit conversion factor.

Given weight: 44 pounds. Conversion factor: 1 kilogram = 2.2 pounds.

This establishes the mathematical relationship needed to convert the weight from the US customary system to the metric system.

2

Set up the appropriate calculation to convert pounds to kilograms.

Divide 44 by 2.2 (44 / 2.2).

Since 1 kilogram is heavier than 1 pound (it equals 2.2 pounds), there will be fewer kilograms than pounds. Therefore, division is the correct operation.

3

Perform the division.

44 / 2.2 = 20.

To divide by a decimal, shift the decimal point one place to the right for both numbers, making it 440 / 22, which exactly equals 20.

Anahtar Kavram

Cevap: 135

Cevap

135

To find the correct answer, three phases are required. First, use the perimeter formula (

P = 2L + 2W

) to find the drawing width:

14 = 2(4.5) + 2W \rightarrow W = 2.5

inches. Next, find the unit scale by dividing

12

yards by

\frac{2}{3}

inch, yielding

18

yards per inch. Multiplying the

2.5

-inch drawing width by

18

gives an actual width of

45

yards. Finally, convert yards to feet by multiplying by

3

, resulting in

135

feet.

Adım Adım Çözüm

1

Determine the width of the park on the scale drawing.

The width on the drawing is

2.5

inches.

The formula for the perimeter of a rectangle is

P = 2L + 2W

. Substituting the given values,

14 = 2(4\frac{1}{2}) + 2W

, which simplifies to

14 = 9 + 2W

. Solving for

W

gives

2W = 5

, so

W = 2.5

.

2

Calculate the unit scale rate.

1

inch on the drawing represents

18

yards in reality.

To find the value of

1

inch, divide the actual distance by the drawing distance:

12 \div \frac{2}{3} = 12 \times \frac{3}{2} = 18

yards per inch.

3

Calculate the actual width of the park in yards.

The actual width is

45

yards.

Multiply the drawing width by the unit scale rate: $2.5 \text{ inches} \times 18 \text{ yards/inch} = 45 \text{ yards}.

4

Convert the actual width from yards to feet.

The final actual width is

135

feet.

There are

3

feet in

1

yard. Multiply the width in yards by

To find the completion time, you must add the total duration to the start time. First, convert 345 minutes into hours and minutes by dividing by 60, which gives 5 hours with a remainder of 45 minutes. Next, add 5 hours and 45 minutes to the launch time of 21:40. Adding the hours gives 26:40. Adding the 45 minutes gives 26:85. Since 85 minutes is equivalent to 1 hour and 25 minutes, this shifts the time to 27:25. Finally, subtract 24:00 to account for crossing midnight, resulting in the correct time of 03:25.

Adım Adım Çözüm

1

Convert the total flight duration from minutes to hours and minutes.

345 minutes ÷ 60 = 5 hours with a remainder of 45 minutes.

Converting to hours and minutes makes it easier to add to the given start time.

2

Add the flight hours to the launch time.

21:40 + 5 hours = 26:40.

This finds the hour of completion before adjusting for the 24-hour clock.

3

Add the remaining flight minutes to the result from Step 2.

26:40 + 45 minutes = 26:85.

This incorporates the remaining minutes of the flight time.

4

Format the resulting time into a standard 24-hour clock format.

26:85 becomes 27:25 (since 85 minutes is 1 hour and 25 minutes). 27:25 on a 24-hour clock is calculated as 27:25 - 24:00 = 03:25.

The correct answer accurately calculates the total final mixture as 196 gallons (56 * 3.5). Using the 3:4 ratio, the coolant represents 3/7 of the total, meaning 84 gallons of coolant are needed. Converting 84 gallons to pints gives 672 pints. The inventory of 20 gallons, 1 quart, and 1 pint equals exactly 163 pints (160 + 2 + 1). Subtracting the 163 pints in inventory from the 672 pints needed leaves a deficit of 509 pints.

Adım Adım Çözüm

1

Calculate the total volume of the final mixture required for all vehicles.

56 vehicles * 3.5 gallons/vehicle = 196 gallons of final mixture.

Determines the total capacity needed before finding the specific amount of concentrated coolant.

2

Determine the volume of concentrated coolant needed.

196 gallons * (3 parts coolant / 7 total parts) = 84 gallons of concentrated coolant.

Applies the part-to-whole ratio (3 parts coolant + 4 parts water = 7 total parts) to find the coolant portion.

3

Convert the required amount of coolant into pints.

84 gallons * 8 pints/gallon = 672 pints.

Prepares the required amount in the target unit (pints) requested by the question. (1 gallon = 4 quarts, 1 quart = 2 pints).

4

Convert the current inventory of coolant into pints.

(20 gallons * 8) + (1 quart * 2) + 1 pint = 160 + 2 + 1 = 163 pints.

Standardizes the inventory volume to pints so it can be subtracted from the total required.

5

Subtract the inventory from the total needed to find the additional amount required.

672 pints - 163 pints = 509 pints.

Finds the exact deficit that must be requisitioned.

Cevabı ve açıklamayı göster

Cevap: 2160

Cevap

2160

The correct answer is found by first determining the unit scale factor. Since 3/8 inch represents 15 miles, dividing 15 by 3/8 reveals that 1 inch represents 40 miles. Multiplying the map dimensions (1.5 inches and 2.25 inches) by 40 gives the actual dimensions of 60 miles and 90 miles. The actual area is the product of these dimensions, or 5,400 square miles. Multiplying the area by 400 trees per square mile yields 2,160,000 total trees. Finally, dividing by 1,000 gives the answer in thousands: 2,160.

Adım Adım Çözüm

1

Calculate the unit scale (miles per inch).

\frac{3}{8}\text{ inch} = 15\text{ miles} \Rightarrow 1\text{ inch} = 15 \times \frac{8}{3} = 40\text{ miles}

Finding the value of 1 inch makes it much easier to convert the mixed-fraction map dimensions.

2

Convert the map width to actual miles.

,

\frac{1}{4} \text{ mile} = 1320 \text{ feet}

. Next, convert the first trench length to feet:

120 \frac{2}{3} \text{ yards} \times 3 \text{ feet/yard} = 362 \text{ feet}

. The second trench is

412 \text{ feet } 8 \text{ inches}

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.

120 \frac{2}{3} \times 3 = 362

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 \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 \text{ feet} - 774 \text{ feet } 8 \text{ inches} = 545 \text{ feet } 4 \text{ inches}

A chemical processing plant uses a rectangular holding tank measuring $4$ feet long, $3$ feet wide, and $2$ feet deep. The tank is currently filled to exactly $25\%$ of its total capacity with an industrial solvent. The plant manager needs to transfer all of this solvent into small safety bottles that each hold $15$ fluid ounces. Given that $1$ cubic foot holds exactly $7.5$ gallons, and $1$ gallon contains $128$ fluid ounces, what is the maximum number of completely full safety bottles that can be filled from the tank?

A carpenter is preparing to install baseboards in a room. One specific section of the wall requires a continuous board that is exactly $2$ yards and $2$ feet long. What is the required length of this board in inches?

Cevabı ve açıklamayı göster

Cevap: 96

Cevap

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 \times 3 = 6

). Adding the extra 2 feet gives a total of 8 feet. Finally, converting 8 feet to inches yields 96 inches (

8 \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 = 96

inches.

Cevabı ve açıklamayı göster

Cevap

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.

To find the finish time, the total duration of

5.4

hours must first be converted into hours and minutes. The

0.4

Adım Adım Çözüm

1

Convert the decimal portion of the scan duration into minutes.

0.4 \text{ hours} \times 60 \text{ minutes/hour} = 24 \text{ minutes}

. The total duration is

5

hours and

24

minutes.

Time is measured in base-60, so fractional hours must be multiplied by 60 to find the equivalent minutes.

2

Add the whole hours to the starting time.

22:45 + 5 \text{ hours} = 27:45

. Subtracting

24

hours for the crossover into the next day gives

03:45

.

This establishes the hour portion of the finish time on the following day.

A tailor is combining two pieces of fabric to make a continuous banner. One piece is $3 \frac{1}{2}$ yards long, and the second piece is $1 \frac{1}{4}$ yards long. After joining them together end-to-end, the tailor needs to cut the combined fabric into smaller segments that are each $15$ inches long. How many complete segments can the tailor cut from the combined fabric?

11

The total length of the fabric is found by adding

3 \frac{1}{2}

yards and

1 \frac{1}{4}

yards, which equals

4 \frac{3}{4}

yards. Because there are

36

inches in one yard, this is equivalent to

4.75 \times 36 = 171

inches. Dividing the total

171

inches by the required segment length of

15

inches gives

11.4

. Therefore,

11

complete segments can be cut.

Adım Adım Çözüm

1

Calculate the total length of the fabric in yards.

3 \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.

4 \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 \div 15 = 11.4

Division determines how many

15

-inch segments fit into the

171

-inch length.

4

Identify the number of complete segments.

2560

Cevabı ve açıklamayı göster

Cevap: 2560

Cevap

2560

The correct answer is found by first converting the 1.8 tons to 3,600 pounds. Next, subtract the 1,200 pounds used for the bulk containers to get 2,400 pounds remaining. Convert this remainder to ounces by multiplying by 16, yielding 38,400 ounces. Finally, dividing by the 15-ounce packet size results in exactly 2,560 packets.

Adım Adım Çözüm

1

Convert the total weight of the shipment from tons to pounds.

1.8 \times 2000 = 3600

pounds

Standardizing the initial weight into pounds is required because the bulk containers are measured in pounds.

2

Calculate the total weight placed into the bulk storage containers.

24 \times 50 = 1200

pounds

This establishes how much of the shipment has already been allocated.

3

Subtract the bulk storage weight from the total weight to find the remaining pounds.

3600 - 1200 = 2400

pounds

This isolates the remaining weight that will be used for the individual meal packets.

4

Convert the remaining weight from pounds to ounces.

2400 \times 16 = 38400

ounces

The meal packets are measured in ounces, so the remaining bulk weight must match these units before dividing.

5

Divide the remaining ounces by the size of each meal packet.

38400 \div 15 = 2560

packets

This final division determines the exact number of packets that can be completely filled.
