Mike owed 3,000 shares of Merck of Corporation and received a quarterly dividend check for 1,140 what was annual dividend for one share of Merck?

Answers

Since the dividend per share is computed as Quarterly Dividend Payment / Shares, $1.52 is the yearly dividend for each share of Merck.

What is an example of a dividend?

One of the four crucial steps in the division process is the dividend. It is necessary to divide the entire into several equal sections. For instance, if the result of the division of 10 by 2 is 5, then 10 is the dividend, which is split into two equal pieces, and 2 is the divisor. The result of the division is 5, the quotient, and the remainder is 0.

According to the given information:

Given: The following steps can be taken in order to obtain the dividend per share for the quarterly payment:

Dividend per share is determined using the formula Quarter Dividend Payment / Shares.

The dividend equals $0.38 per share when $1,140 is divided by 3,000 shares.

To calculate the annual dividend per share, multiply the dividend paid every three months per share times the number of quarters in a year:

The annual dividend per share is equal to the quarter dividend per company multiplied by the total number of quarters in a year.

The annual dividend per share is calculated as $0.38 multiplied by four quarters, or $1.52 per share.

Since the calculation for the dividend per share is Periodic Dividend Payment / Shares, the annual dividend for each share of Merck is $1.52.

Answers

The value of X=8 when the bases have lengths of 2x+4 and 8x-50

A trapezoid is a quadrilateral with exactly one pair of parallel sides. The parallel sides are called the bases of the trapezoid. The nonparallel sides are referred to as the legs of the trapezoid.

A median of a trapezoid is the segment that joins the midpoints of the nonparallel sides (legs). The median is also parallel to the two bases, and it is the average length of the two bases.

The formula to find the median is

median=a+b/2

where a and b are the lengths of the bases or parallel sides.

we have the values of a=2x+5 b=8x-50 m=17 now substitute the values in the above formula and we get x value:

The customer service department of a company found that the relationship between the number of minutes a customer spends on hold when telephoning and the customer's level of satisfaction on a 10-point scale can be approximated by the equation y=10−0.1x
, where x
is the number of minutes on hold and y
is the level of satisfaction. What does 0.1 represent in the equation?

Answers

In the equation y = 10 - 0.1x, the coefficient 0.1 represents the slope of the line.

Define slope

it represents the rate of change of y with respect to x, which is the amount by which y changes for every unit increase in x.

In this case, the slope is negative (-0.1), which means that as the number of minutes on hold (x) increases by 1 unit, the level of satisfaction (y) decreases by 0.1 units.

In other words, the longer a customer spends on hold, the lower their level of satisfaction is likely to be. The slope is a key parameter in the equation and provides valuable information about the relationship between the two variables.

What is area ?

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

Here, we have,

Since the rectangle has a length of 4 meters and a width of 9 meters we need to find the area of rectangle

Area of rectangle  = length × width

Area of rectangle = 4 m × 9 m

Area of rectangle = 36 m^2

Since the  triangle has a base of 6 meters (9 meters - 3 meters o) and a height of 3 meters we need to find the Area of triangle

Area of triangle  = (1/2) × base × height

Area of triangle  = (1/2) × 6 m × 3 m

Area of triangle  = 9 m^2

Now let find the total area of the composite figure

Total area = Area  of rectangle + Area of triangle

Total area = 36 m^2 + 9 m^2

Total area = 45 m^2

Therefore the total area of the figure is 45 square meters.

The solution to the questions are:

The width, labelled x in the figure is 87.5 metersThe length, labelled 350-2 x in the figure, is 175 metersThe largest area that can be enclosed is 15312.5 square meters

How to determine the width and the length of the rectangle?

From the question, we have the following parameters that can be used in our computation:

Length = 350 - 2x

Width = x

The area of a rectangle is the product of its dimensions

So, we have

Area = Length x Width

Substitute the known values in the above equation, so, we have the following representation

A = (350 - 2x) * x

Evaluate

A = 350x - 2x²

Differentiate and set to 0

350 - 4x = 0

So, we have

4x = 350

Divide by 4

x = 87.5

Recall that

Length = 350 - 2x

So, we have

Length = 350 - 2 x 87.5

Evaluate

Length = 175

The area is then calculated as

Area = Length x Width

So, we have

Area = 175 x 87.5

Evaluate

Area = 15312.5 square meters

Hence, the area is 15312.5 square meters

For the question of total area of the cuboid is 200cm^.
I understand where we divide 150 by 4.
But why do I need to multiply by 5, when there are 6 faces.

Answers

You need to multiply by 5 instead of 6 because each pair of opposite faces on a cuboid has the same area, so by considering one face from each pair, you ensure that you don't count any face twice.

When calculating the total surface area of a cuboid, you need to understand the concept of face pairs.

A cuboid has six faces, but each face has a pair that is identical in size and shape.

Let's break down the reasoning behind multiplying by 5 instead of 6 in the given scenario.

To find the surface area of a cuboid, you can add up the areas of all its faces.

However, each pair of opposite faces has the same area, so you avoid double-counting by only considering one face from each pair. In this case, you have five pairs of faces:

(1) top and bottom, (2) front and back, (3) left and right, (4) left and back, and (5) right and front.

By multiplying the average area of a pair of faces by 5, you account for all the distinct face pairs.

Essentially, you are considering one face from each pair and then summing their areas.

Since all the pairs have the same area, multiplying the average area by 5 gives you the total surface area.

When dividing 150 by 4 (to find the average area of a pair of faces), you are essentially finding the area of a single face.

Then, by multiplying this average area by 5, you ensure that you account for all five pairs of faces, providing the total surface area of the cuboid.

Thus, multiplying by 5 is necessary to correctly calculate the total surface area of the cuboid by accounting for the face pairs while avoiding double-counting.

Twelve cards are numbered from 1 to 12 and placed in a box. One card is selected at random and not replaced. Another is randomly selected. What is the probability of selecting two even numbers?

Answers

In this case, we are to determine the probability of selecting two even numbers. This can be solved as follows:There are six even numbers: {2, 4, 6, 8, 10, 12}.We can use the concept of conditional probability since the first event affects the probability of the second event. This can be expressed as follows:

In this case, P(A) represents the probability of selecting an even number, and P(B|A) represents the probability of selecting an even number given that the first card selected was even. P(A) = 6/12 = 1/2 (there are six even numbers and twelve cards in total)P(B|A) = 5/11 (there are five even numbers left in the box after the first even number is selected, and eleven cards are left in total).

The probability of selecting two even numbers can be found by multiplying these probabilities: P(A) x P(B|A) = (1/2) x (5/11) = 5/22Therefore, the probability of selecting two even numbers is 5/22.Answer: 5/22

The graph below shows triangle A and triangle B. The side lengths of triangle A are proportional to the side lengths of triangle B, and the corresponding angle measures of the two triangles are equal. image b63beb85ff8941fb976339f638c35c47 Which statement BEST describes the relationship between triangle A and triangle B? A The triangles are similar but not congruent. B The triangles are congruent but not similar. C The triangles are both similar and congruent. D The triangles are neither similar nor congruent.

Answers

Answer:A.The triangles are similar but not congruent

Step-by-step explanation:

In a congruent traingle:

the both triangles are same in shape and size

There are five theorems to see if the triangles are congruent

and neither particularly applies here

sss: the sides are not equal

as none of the sides are equal, then despite the angles, congruence is not possible

However it is evident that one of the triangles is proportionally bigger than the other but similar. Hence A is correct.

Step-by-step explanation:

USE=UST+EST

180=UST+22x+3 ==> USE is a straight line, and straight lines measure 180 degrees and are called straight angles.

UST+6x+4+79=180 ==> 180 is the sum of all three angles in a triangle

UST+22x+3=UST+6x+4+79 ==> they both equal 180

22x+3=6x+4+79 ==> subtract UST on both sides

22x+3=6x+83

22x+3-3=6x+83-3

22x=6x+80

22x-6x=6x-6x+80

16x=80

x=80/16
