The sum and difference between nine-tenths and seven-eighths is 71/40 and 1/40, calculated by addition and subtraction.

As per the fact, representing the words in numbers. So, nine tenths will be represented as: 9/10

Seven eighths: 7/8

Calculating the sum and difference as follows -

Sum = 9/10 + 7/8

Taking LCM we get 40

Sum = 9×4 + 7×5/40

Performing multiplication on Right Hand Side of the equation

Sum = 36 + 35/40

Sum = 71/40

Difference = 9/10 - 7/8

Difference = (9×4) - (7×5)/40

Performing multiplication on Right Hand Side of the equation

Difference = 36 - 35/40

Difference = 1/40

Hence, sum is 71/40 and difference is 1/40.

Step-by-step explanation:

OK so your gonna add 6 and 11 then multiply it by 3, the height. then your gonna divide by 2

Answer:

-5(7a+ 6)

Explanation:

Given the expression:

-35a - 30

-35a = -5 * 7 * a

-30 = -5 * 6

You can see from the factors that -5 is common to both

Hence -5 is the GCF

Factoring out -5 from the expression will give;

-5(7a+ 6)

This gives the correct factor

A NORMAL distribution is a symmetrical probability distribution with a bell-shaped curve. It is also called a Gaussian distribution or a normal curve. This distribution is often used in statistics to represent a large number of natural phenomena, such as the distribution of height, weight, or IQ scores in a population.

The first deviation of a NORMAL distribution includes 68.2% of the data. This means that if we were to take a random sample of data from a normally distributed population, about 68.2% of the data would be within one standard deviation of the mean.

The second deviation includes 95.4% of the data. This means that about 95.4% of the data would be within two standard deviations of the mean.

The third deviation includes 99.7% of the data. This means that about 99.7% of the data would be within three standard deviations of the mean.

It is important to note that while these percentages hold true for a NORMAL distribution, they may not apply to other types of distributions.

The question is an illustration of proportion and percentages

The percentage of young adults, age 18-25 were not current alcohol users is 34.92%

The attached graph represents the proportion of those that are surveyed.

From the graph, we have:

\(\mathbf{Total = 18.6 + 27.2 + 20.8 + 11.3}\)

\(\mathbf{Total = 77.9}\)

The number of young adults 18 - 25 that are not current alcohol users are:

\(\mathbf{Young\ adults = 27.2}\)

So, the percentage of this group is:

\(\mathbf{\% Young\ adults = \frac{Young\ adults}{Total} \times 100\%} }\)

This gives

\(\mathbf{\% Young\ adults = \frac{27.2}{77.9} \times 100\%} }\)

\(\mathbf{\% Young\ adults = 0.3492 \times 100\% }\)

Multiply

\(\mathbf{\% Young\ adults = 34.92 \% }\)

Hence, the percentage of young adults, age 18-25 were not current alcohol users is 34.92%

Answer:

(1/2)(32 ft/sec^2)((7 sec)^2)

= (16 ft/sec^2)(49 sec^2)

= 784 feet

Height = 112 feet.

To find the height of the window, we can use the following kinematic equation for motion with constant acceleration:

y = yo + voyt + ½at²

Here, y is the final height of the ball above the ground, yo is the initial height of the ball (which is the height of the window in this case), voy is the initial velocity of the ball (which is 0 because the ball is dropped from rest), t is the time taken for the ball to hit the ground (which is 7 seconds), and a is the acceleration due to gravity (which is 32 ft/s²).

Substituting the values, we have:y = yo + 0 + ½(32)(7)

Simplifying the expression, we get:y = yo + 112

Thus, the height of the window (in feet) is given by:y = 112 feet

To remove the single quotation marks ('') at the beginning and end of a string and remove the item at index 12, you can use Python's string manipulation methods and list slicing. First, you can use the strip() method to remove the surrounding single quotation marks. Then, you can convert the string into a list using the list() function, remove the item at index 12 using list slicing, and finally convert the list back into a string using the join() method.

To remove the single quotation marks at the beginning and end of a string, you can use the strip() method. This method removes any leading and trailing characters specified in the argument. In this case, you can pass the single quotation mark ('') as the argument to strip().

Here's an example:

string = "'example string'"

stripped_string = string.strip("'")

After executing this code, the value of stripped_string will be 'example string' without the surrounding single quotation marks.

To remove the item at index 12 from the string, you need to convert it into a list. You can use the list() function for this conversion. Then, you can use list slicing to remove the item at index 12 by excluding it from the list. Finally, you can convert the modified list back into a string using the join() method.

Here's an example:

string_list = list(stripped_string)

string_list.pop(12)

result_string = ''.join(string_list)

After executing this code, the value of result_string will be the modified string with the item at index 12 removed.

The market rate of return on the Dayton Rapur stock is approximately 4.59%.

To calculate the market rate of return on the Dayton Rapur stock, we need to use the dividend discount model (DDM). The DDM calculates the present value of expected future dividends and divides it by the current stock price.

First, let's calculate the expected dividend for the next year. The annual dividend is $2.17 per share, and it increases by 2.56% annually. So the expected dividend for the next year is:

Expected Dividend = Annual Dividend * (1 + Annual Dividend Growth Rate)

Expected Dividend = $2.17 * (1 + 0.0256)

Expected Dividend = $2.23

Now, we can calculate the market rate of return using the DDM:

Market Rate of Return = Expected Dividend / Stock Price

Market Rate of Return = $2.23 / $48.49

Market Rate of Return ≈ 0.0459

Finally, we convert this to a percentage:

Market Rate of Return ≈ 0.0459 * 100 ≈ 4.59%

Therefore, the market rate of return on the Dayton Rapur stock is approximately 4.59%.

Answer:

The shortest path to take is \(20\sqrt{3}\ cm\) or \(34.64\ cm\)

Step-by-step explanation:

This question requires an attachment (See attachment 1 for question)

Given

Cube Dimension: 20cm * 20cm

Required

Shortest path from A to B

For proper explanation, I'll support my answer with an additional attachment (See attachment 2)

The shortest path from A to B is Line labeled 2

But first, the length of line labeled 1 has to be calculated;

This is done as follows;

Since, the cube is 20 cm by 20 cm

\(Line1^2 = 20^2 + 20^2\) (Pythagoras Theorem)

\(Line1^2 = 2(20^2)\)

Take square root of both sides

\(Line1 = \sqrt{2(20)^2}\)

Split square root

\(Line1 = \sqrt{2} * \sqrt{20^2}\)

\(Line1 = \sqrt{2} * 20\)

\(Line1 = 20\sqrt{20}\)

Next is to calculate the length of Line labeled 2

\(Line2^2 = Line1^2 + 20^2\) (Pythagoras Theorem)

Substitute \(Line1 = 20\sqrt{20}\)

\(Line2^2 = (20\sqrt{2})^2 + 20^2\)

Expand the expression

\(Line2^2 = (20\sqrt{2})*(20\sqrt{2}) + 20 * 20\)

\(Line2^2 = 400*2 + 400\)

Factorize

\(Line2^2 = 400(2+1)\)

\(Line2^2 = 400(3)\)

Take square root of both sides

\(Line2 = \sqrt{400(3)}\)

Split square root

\(Line2 = \sqrt{400} * \sqrt{3}\)

\(Line2 = 20 * \sqrt{3}\)

\(Line2 = 20 \sqrt{3}\)

The answer can be left in this form of solve further as follows;

\(Line2 = 20 * 1.73205080757\)

\(Line2 = 34.6410161514\)

\(Line2 = 34.64 cm\) (Approximated)

Hence, the shortest path to take is \(20\sqrt{3}\ cm\) or \(34.64\ cm\)

Answer:

44.72 cm

Step-by-step explanation:

1. This was marked correct by RSM

2. Unfold the cube, so that points A and B and on points diagonal from each other on a 40 cm x 20 cm rectangle. Now draw a line connecting points A to B. That is the hypotenuse of both triangles. Now according to the pythagorean theorem, the hypotenuse is √2000, which is equal to 5√20.

3. The answer is 44.72 cm

A regular polygon with angles that all measure 162 degrees has 20 sides.

Let's first consider a formula to find the measure of an interior angle of a regular polygon. We can use the formula:

Interior angle = (n-2) x 180 / n,

where n is the number of sides of the polygon.

If all angles of the polygon measure 162 degrees, then we can set up an equation:

(n-2) x 180 / n = 162

Multiplying both sides by n, we get:

(n-2) x 180 = 162n

Expanding the left side, we get:

180n - 360 = 162n

Subtracting 162n from both sides, we get:

18n - 360 = 0

Adding 360 to both sides, we get:

18n = 360

Dividing both sides by 18, we get:

n = 20

The cube has an edge length of x inches, and the protective coating has a thickness of 1 inch.The amount of coating needed for the cube with a protective coating 1 inch thick is 6L² square inches.

The total dimensions of the cube including the coating is (x + 2) inches.

So, the volume of the cube plus the coating can be calculated by using the formula:

V = (x + 2)³ - x³

  = (x³ + 6x² + 12x + 8) - x³

   = 6x² + 12x + 8 cubic inches

Therefore, a production manager should order 6x² + 12x + 8 cubic inches of coating for such cubes.

To calculate the amount of coating needed for a cube with a protective coating of 1 inch thick, we need to find the surface area of the cube and then multiply it by the thickness of the coating.

The surface area of a cube can be calculated using the formula:

Surface Area = 6 * (edge length)²

Let's assume the edge length of the cube is represented by "L" inches.

The surface area of the cube is:

Surface Area = 6 * (L)²

                     = 6L² square inches

To find the amount of coating needed, we multiply the surface area by the thickness of the coating:

Coating needed = Surface Area * Thickness

                          = 6L² * 1 inch

Therefore, the amount of coating needed for the cube with a protective coating 1 inch thick is 6L² square inches.
