I need help. I’m a little bit confused

the formula for y in terms of x is: y = (2x * inches) / 5 centimeters

To write a formula for y in terms of x, given the conversion 25 centimeters = 10 inches, we can use the concept of proportions.

We can set up a proportion between the given values:

x centimeters / y inches = 25 centimeters / 10 inches

To solve for y, we can cross-multiply:

x * 10 inches = y * 25 centimeters

Now, we isolate y by dividing both sides of the equation by 25 centimeters:

y = (x * 10 inches) / 25 centimeters

Simplifying further:

y = (2x * inches) / 5 centimeters

Therefore, the formula for y in terms of x is:

y = (2x * inches) / 5 centimeters

Answer:

(b)  33919

(c)  8 ¹/₃

Step-by-step explanation:

⇒ 317 × 107 = (300 + 10 + 7)(100 + 7)

                    = 300(100 + 7) + 10(100 + 7) + 7(100 + 7)

                    = 30000 + 2100 + 1000 + 70 + 700 + 49

                    = 30000 + 2000 + 100 + 1000 + 70 + 700 + 40 + 9

                    = 30000 + 2000 + 1000+ 700 + 100 + 70 + 40 + 9

                    = 30000 + 3000 + 800 + 110 + 9

                    = 30000 + 3000 + 800 + 100 + 10 + 9

                    = 30000 + 3000 + 900 + 10 + 9

The net profit margin for this shirt is 55%.

What is net profit?

Net profit is the amount of money your business earns after deducting all operating, interest and tax expenses over a period of time. To arrive at this value, you need to know the company's gross profit. If the value of net profit is negative, it is called net loss.

Net profit is another important parameter that determines the financial health of your business. It shows whether the company can earn more than it spends. Net profit helps you decide when and how to expand your business and when to cut costs.

It is important for a business owner to know the difference between profit and profitability. Profit is an absolute number equal to revenues minus expenses. Profitability, on the other hand, is a relative number (percentage) that equals the ratio of profit to revenue.

Profitability is a measure of efficiency and is useful in determining the success or failure of a business.

Given,

Revenue = $12

Cost of goods sold = $3

Operating expenses = 20% of revenue = 20/100 x $12 = $2.4

We know,

Net Profit = Revenue - Cost of goods sold - Operating expenses

\(Net \: Profit = 12 - 3 - 2.4\)

Hence, Net Profit = $6.6

Again,

Net Profit Margin = (Net Profit / Revenue) x 100%

Net Profit Margin \(= ( \frac{6.6}{ 12}) \times 100\%\)

SO, Net Profit Margin = 55%

Therefore, the net profit margin for this shirt is 55%.

So, it is clear that choice A is correct.

The surface area of the composite solid is S = 870 m²

Given data ,

Let the surface area of the composite solid be S

Now , the surface area of the rectangle = R

And , the surface area of triangular prism = T

Answer:

$75.14

Step-by-step explanation:

The new value of one share of LMNOP stock after 11.6% increment is $75.14

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

\(\dfrac{a}{100} \times b\)

For this case, we are given that:

Now, the 11.6% of initial price is:

\(\dfrac{85}{100} \times 11.6 = \$9.86\)

Thus, the final price of the stock in December =  $85 - $9.86 = $75.14

To find the possible code numbers, we can start by using the clues one by one and narrowing down the possibilities:

- The number is between 8,500 and 8,800, so we know the first digit is 8 and the second digit is either 5, 6, 7, or 8.

- When multiplied by 8, the result is a whole number, which means the number must be divisible by 8. The only possibilities in our range are 8,512, 8,528, 8,544, 8,560, 8,576, 8,592, 8,608, 8,624, 8,640, 8,656, 8,672, 8,688, 8,704, 8,720, 8,736, 8,752, 8,768, 8,784, and 8,800.

- The sum of all digits in the number is 26, which means we can eliminate some possibilities. For example, 8,512 has a digit sum of 16, so it's not a valid option. Similarly, 8,800 has a digit sum of 16, so it's also not a valid option. We can eliminate other possibilities that don't add up to 26 as well.

- The digit in the hundreds place is ¾ the digit in the thousands place. This narrows down the possibilities even further. The thousands digit must be divisible by 4 and greater than or equal to 2. That means the thousands digit can only be 2, 4, 6, or 8. We can use this information to eliminate some more possibilities.

- The digit in the hundredths place is 200% of the digit in the tenths place. This means the tenths digit cannot be 0 or 5, because otherwise the hundredths digit would be 0. That leaves us with the possibilities 1, 2, 3, 4, 6, 7, 8, and 9.

- There are no zeros in the decimal places, so we can eliminate 8,560 and 8,640.

- Putting all of this information together, we can narrow down the possibilities to 8,576, 8,608, 8,672, and 8,688.

To make it so there is only one possible code number, we can add one more clue:

- The number is not divisible by 9.

This eliminates 8,640 and 8,688, leaving us with the only possible code number:

Code number: 8,576

We used all of the given clues to eliminate possibilities and narrow down the valid options. Adding the additional clue that the number is not divisible by 9 made it so there was only one possible code number.

Just like any conversion of units, we just set up the starting amount and multiply it by the correct ratio:

    5 days (1 year/ 365 days) = 5/365 years = 0.014 years

You just need to make sure you choose the right ratio. In this case, I know that 1 year is 365 days, and I'm trying to cancel the days unit, therefore I put the year in the numerator and the days in the denominator.

Step-by-step explanation:

The number of digits that are there is 25 digits.

Let the sum of the numbers be x.

Also, let the number of digits there be y

So, we get that:

Average of numbers originally = x / y

Now,

(x + 25) / y = x / y + 1

(x + 25) / y = (x + y) / y

x + 25 = x + y

y = 25

Step-by-step explanation:

the area of a rectangle is

length × width = 300 ft²

length = width + 5

(width + 5) × width = 300

width² + 5×width = 300

width² + 5×width - 300 = 0

the general solution to such a quadratic equation is

width = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = 5

c = -300

width = (-5 ± sqrt(5² - 4×1×-300))/(2×1) =

= (-5 ± sqrt(25 + 1200))/2 =

width1 = (-5 + 35)/2 = 30/2 = 15 ft

width2 = (-5 - 35)/2 = -40/2 = -20 ft

negative lengths for an actual object don't make sense, so width = 15 ft is our solution.

Step-by-step explanation:

Pythagorean theorem:

\(a^2+b^2 = c^2\). where a and b are the sides and c is the hypotehnus (the side in front of the 90 degree angle)

\(22^2 + b^2 = 25^2\\484 + b^2 = 625\\b^2 = 625-484\\b^2 = 141\\b = \sqrt{141} \\b = 11.9\)

Answer:

11.9

Step-by-step explanation:

This is a right triangle so I can solve this with the pythagorean theorem.

Set up the equation 22²+x²=25² x would be the third side

Simplify, 484+x²=625

Subtract from both sides 484-484+x²=625-484

x²=141

Find the square root of 141 to get x

The square root of 141 is approximately 11.9 rounded to the nearest tenth.

The net present value (NPV) for a 25-year project with an initial investment of $5,000 and a cash inflow of $2,000 per year, assuming that the firm has an opportunity cost of 15%, is $9,474.23.

NPV is a method used to determine the present value of cash flows that occur at different times.

The net present value (NPV) calculation considers both the inflows and outflows of cash in each year of the project. The NPV is then calculated by discounting each year's cash flows back to their present value using a discount rate that reflects the firm's cost of capital or opportunity cost.

A 25-year project with an initial investment of $5,000 and a cash inflow of $2,000 per year has a total cash inflow of $50,000 ($2,000 × 25).

Summary: Thus, the net present value (NPV) for a 25-year project with an initial investment of $5,000 and a cash inflow of $2,000 per year, assuming that the firm has an opportunity cost of 15%, is $9,474.23.
