What is unit conversion?

In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.

The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.

A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.

Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.

Given data ,

Let the total yards of tubing the plumber will use be A

Now , the equation is

Let the total inches of tubing used for each washing machine = 16 inches

And , from the unit conversion ,

16 inches = ( 16/36 ) yards

So , the number of washing machines = 18 machines

Now , the total yards of tubing the plumber will use A = number of washing machines x 0.444

On simplifying , we get

The total yards of tubing the plumber will use A = ( 16 / 36 ) x 18

The total yards of tubing the plumber will use A = 8 yards

Hence , the total yards is A = 8 yards

Answer 2
Answer: You would multiply 18 machines x 16" for a total of 288 inches. You would then divide by 36 because there are 36" (or 3 feet) in a yard. The answer is 8 yards of tubing.

Find the sum of the value of 8 in 387,562 and the value of 7 in 7,328,562

Answers

387,562
The 8 is in the ten thousands place, so it equals 80,000.

7,328,562
The 7 is in the millions place, to it equals 7,000,000.

The sum is the value of two numbers added together (the answer to an addition problem).

80,000 + 7,000,000 = 7,080,000

Mrs. Ferguson looked at another hotel. She waited a week before she decided to book nights at that hotel, and now the prices have increased. The original price was $1589. The price for the same room and same number of nights is now $2075. What is the percent increase? Round to the nearest percent. Show your work. Will you plaes explain this ?

Answers

To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. If your answer is a negative number then this is a percentage decrease.

2075-1589=486

486*100/1589=30.58%

Rounding it we get,
30.6%
=31%



What is the greatest common factor of 12x^3 - 9x^2?A) 3x

B) 6x

C) 3x^2

Answers

Answer:the answer is C 3x^2

Step-by-step explanation:

Final answer:

The greatest common factor of 12x^3 - 9x^2 is 3x^2.

Explanation:

The greatest common factor (GCF) of 12x^3 - 9x^2 can be found by factoring out the common factors of the terms. In this case, both terms have a common factor of 3x^2. By factoring out 3x^2, we get:

12x^3 - 9x^2 = 3x^2(4x - 3)

Therefore, the greatest common factor is 3x^2 (option C).

A school has 679 bottles of water for sports day.They buy another 8 packs of bottled water.
Each pack contains 6 bottles.
How many bottles of water do they have in total?

Answers

The school starts off with 679 bottles of water. 

They then buy 8 packs with 6 bottles in each: 
8 X 6 = 48

To calculate the total you must add the amount of bottles they originally had to the amount of purchased bottles:
679 + 48 = 727

The school therefore has 727 bottles of water in total. 

727 because first you need to find out the amount which is 4*6 then you need to add it together 679+48 check it over just in case

A submarine is 1,275.5 feet below sea level. It dives down 215.5 feet and then rises 125.5 feet. Finally, the sub dives down another 122.4 feet. Assume sea level is at an elevation of 0 feet.After its final dive, the submarine is at an elevation of________
feet.

Answers

Answer:

The elevation of submarine is −1487.5 feet that means the submarine is 1487.5 feet below the sea level.

Step-by-step explanation:

We are given the following information in the question:

A submarine is 1,275.5 feet below sea level.

It dives down 215.5 feet

It rises 125.5 feet.

Finally, the sub dives down another 122.4 feet.

We are given that the sea level is at an elevation of 0 feet.

Elevation of submarine is given by:

-1275.5-215.5+125.5-122.4 = -1487.5

The elevation of submarine is −1487.5 feet that means the submarine is 1487.5 feet below the sea level.

I believe that the correct answer would be 1,487.9 after its final dive.
