In circulation is 6% cumulative preferred stock for ABC Corporation. ABC distributed a 6% preferred dividend two years ago. ABC distributed a 4% preferred stock dividend last year. The minimum payout to preferred stockholders is 8%.
As per the given information, ABC Company has outstanding 6% cumulative preferred stock. This means that the preferred shareholders are entitled to receive a dividend at a fixed rate of 6% every year before any dividend is paid to the common shareholders.
The term "cumulative" implies that any unpaid dividends from previous years must be paid before any dividends can be paid to the common shareholders.
Now, we are given that two years ago, ABC paid a 6% preferred dividend. This means that the preferred shareholders received their full dividend payment for that year.
ABC distributed a 4% preferred stock dividend last year. This means that the preferred shareholders did not receive their full dividend payment for that year, and there is an unpaid amount of 2% (6% - 4%) from the previous year.
Since the preferred stock is cumulative, the unpaid dividends from the previous year must be paid before any dividend is paid to the common shareholders. Therefore, this year, ABC must pay the preferred shareholders their full dividend of 6% for the current year, as well as the unpaid amount of 2% from the previous year, totalling 8%.
To summarize, this year, ABC must pay the preferred shareholders a dividend of 8% before any dividend is paid to the common shareholders.

A popular college football stadium accommodates 92,000 fans. Ten percent of the highest-priced seats are available in the suites at
the stadium. A suite seat sells for $200 per game, while the other 90 percent of seats sell for $60 each per game. The stadium sells
out for each home game. A small nonconference team has agreed to play two years consecutively as the opposing team at the large
stadium if the home team will pay the smaller nonconference school $1.5 million each year.
Questions (MUST SHOW YOUR WORK)
1. How many seats in the stadium are classified as suite seats?
2. How many seats in the stadium are not suite seats?
3. How much revenue will the stadium generate from suite seats if all the suite seats are purchased for one game?
4. How much revenue will the stadium generate from non-suite seats if all the non-suite seats are purchased for one game?
5. What is the revenue earned at one sold-out game?
6. What is the net revenue of one sold-out game in which the nonconference team plays at the big stadium?
Answer:
1. The number of suite seats is 10% of the highest-priced seats, which is 10% of 92,000 = 9,200 seats.
2. The number of non-suite seats is 90% of the highest-priced seats, which is 90% of 92,000 = 82,800 seats.
3. The revenue generated from suite seats if all are purchased for one game is 9,200 x $200 = $1,840,000.
4. The revenue generated from non-suite seats if all are purchased for one game is 82,800 x $60 = $4,968,000.
5. The revenue earned at one sold-out game is the sum of the revenue from suite seats and non-suite seats: $1,840,000 + $4,968,000 = $6,808,000.
6. The net revenue of one sold-out game in which the nonconference team plays at the big stadium is the revenue earned at one sold-out game minus the payment to the nonconference team: $6,808,000 - $1,500,000 = $5,308,000.

y=log(1/4)x^5
The inverse of the equation y = log(1/4)[tex]x^{5}[/tex] is x = 1/([tex]y^{(log(4)/5)}[/tex]).
What is an inverse equation?
To find the inverse of the equation y = log(1/4)[tex]x^{5}[/tex], we can follow these steps:
Step 1: Interchange the x and y variables to obtain x = log(1/4)[tex]y^{5}[/tex].
Step 2: Solve for y in terms of x. To do this, we need to isolate the y term on one side of the equation. We can start by taking both sides of the equation to the power of 1/5:
[tex]x^{1/5}[/tex] = log(1/4)y
y = [tex](1/4)^{(1/log(x^(1/5)))}[/tex]
Step 3: Simplify the expression. Recall that [tex]a^b^{c}[/tex], so we can rewrite the exponent in the denominator as log([tex]x^{1/5}[/tex]) = (1/5)log(x). Substituting this into the expression for y, we get:
y = [tex](1/4)^{(1/(log(x^(1/5))))}[/tex]
= [tex](1/4)^{(1/((1/5)log(x)))}[/tex]
= [tex](1/4)^{(log(x)/5)}[/tex]
= [tex]x^{(log(1/4)/5)}[/tex]
= [tex]x^{(-log(4)/5)}[/tex]
= 1/([tex]x^{(log(4)/5)}[/tex])
Therefore, the inverse of the equation y = log(1/4)[tex]x^{5}[/tex] is x = 1/([tex]y^{(log(4)/5)}[/tex]).

A real estate broker decides to lease a car for 36 months. Suppose the anual interest rate is 7.8%, the negotiated price is $49,000, there is no trade-in, and the down payment is $4,000. Find the monthly lease payment (in dollars). Assume that the residual value is 49% of the MSRP of $51,500. (Round your answer to the nearest cent.)
To calculate the monthly lease payment, we need to use the formula:
Monthly Payment = Depreciation + Finance Charge
The depreciation represents the portion of the car's value that is lost during the lease period, while the finance charge is the interest charged on the lease.
First, let's calculate the depreciation:
MSRP = $51,500
Residual Value = 49% of MSRP = 0.49 x $51,500 = $25,235
Depreciation = (Negotiated Price - Residual Value - Down Payment) / Lease Term
Depreciation = ($49,000 - $25,235 - $4,000) / 36 = $541.53
Next, let's calculate the finance charge:
Lease Balance = (Negotiated Price - Down Payment) - Residual Value
Lease Balance = ($49,000 - $4,000) - $25,235 = $19,765
Money Factor = Annual Interest Rate / 2400
Money Factor = 7.8% / 2400 = 0.00325
Finance Charge = Lease Balance x Money Factor
Finance Charge = $19,765 x 0.00325 = $64.26
Finally, we can calculate the monthly payment:
Monthly Payment = Depreciation + Finance Charge
Monthly Payment = $541.53 + $64.26 = $605.79
Therefore, the monthly lease payment is $605.79.

A bag of the same size balls contains six blue balls firebrand balls five yellow balls and four green balls what is the probability of selecting a blue or green ball on the first draw
The probability of selecting a blue or green ball on the first draw is 2/3 or approximately 0.67.
What is probability ?
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 indicates that the event is impossible, and 1 indicates that the event is certain to occur. If an event has a probability of 0.5, it means that the event is equally likely to occur or not occur. The probability of an event can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
Probability is an important concept in mathematics, statistics, and many other fields, as it allows us to make predictions and decisions based on the likelihood of certain outcomes.
According to the question:
The total number of balls in the bag is:
6 blue balls + 5 yellow balls + 4 green balls = 15 balls
The probability of selecting a blue or green ball on the first draw can be found by dividing the number of blue and green balls by the total number of balls:
P(blue or green) = (number of blue balls + number of green balls) / (total number of balls)
P(blue or green) = (6 + 4) / 15
P(blue or green) = 10 / 15
P(blue or green) = 2/3
Therefore, the probability of selecting a blue or green ball on the first draw is 2/3 or approximately 0.67.

You will notice that the triangle is sharing one side with the square. And the length of the side is 12 cm. Thus:
x = √(20² - 12²) (Pythagoras)
x = 16 cm
area of the figure = area of square + area of triangle
area of the figure = L² + (1/2 * base * height)
area of the figure = 12² + (1/2 * 16 * 12)

A rectangular garden is 25 feet long and 13 feet wide. A brick walk way with uniform width is going to be constructed around the garden. The brick walk way will have an area of 287 square feet. What should be the width of the brick walk way? Type in your answer to the nearest thousandth. The width of the walk way should be
feet wide.
The width of the walkway around the rectangular garden should be approximately 2.061 feet wide.
What is rectangle?
A rectangle is a type of quadrilateral with four sides and four right angles (90-degree angles). It is characterized by two pairs of parallel sides of equal length.
Let's represent the width of the brick walkway by "x" feet.
Then the dimensions of the entire rectangle including the brick walkway will be [tex]$(25+2x)$[/tex] feet by [tex]$(13+2x)$[/tex] feet.
The area of the rectangle with the walkway will be:
[tex]$$(25+2x)(13+2x)$$[/tex]
We know that the area of the walkway itself is 287 square feet. So we can set up the following equation:
[tex]$$(25+2x)(13+2x) - 25\cdot 13 = 287$$[/tex]
Simplifying and solving for x, we get:
[tex]$$4x^2 + 86x - 216 = 0$$[/tex]
Using the quadratic formula, we get:
[tex]$x = \frac{(-86 \pm \sqrt{86^2 - 4(4)(-216)})}{2(4)}$$[/tex]
[tex]$$x \approx 2.061 \text{ or } x \approx -26.311$$[/tex]
Since the width of the walkway cannot be negative, we reject the negative solution. Therefore, the width of the walkway should be approximately 2.061 feet wide (rounded to the nearest thousandth).

What is rectangle?
A rectangle is a two-dimensional geometric shape with four straight sides and four right angles (90 degrees). It is a type of quadrilateral, which means it has four sides. The opposite sides of a rectangle are equal in length, and the adjacent sides are perpendicular to each other.
The formula for calculating the area of a rectangle is A = l x w, where "A" is the area, "l" is the length, and "w" is the width. The perimeter of a rectangle can be calculated by adding the lengths of all four sides, which is given by the formula P = 2(l + w).
Rectangles are commonly found in many aspects of everyday life, such as in buildings, furniture, electronic devices, and books. They can be used in architecture and engineering for creating stable and functional structures. In mathematics, rectangles are often used in geometry and algebraic expressions, as well as in statisticalanalysis and graphing.
Here we have a rectangle with length 16m and breadth 13 m.
Now, area of the rectangle is length × breath = 13×16 = 208 m².
And here we also have two square parts with side 4 m .
So, area of the square is side × side = 4×4 = 16 m².
Now, numbers of square are 2.
So, total area of two square is (2×16) = 32 m².
If we will subtract the total area of two square from area of the rectangle then we will get the area of shaded region .
So, area of the shaded region [tex] = 208 - 32 = 176 \: {m}^{2} [/tex]
Therefore, area of the shaded region is 176 m² .
Here compound shapes are one rectangle and two squares.

Part (a) replies provide us with the instantaneous rates of change in sales derivatives at t=2, t=3, and t=4 months, respectively. These are 372, 327, and 252 in tens of thousands of dollars each month, respectively.
what is derivative?In mathematics, the derivative of a function with real variables measures how sensitively the function's value varies in reaction to changes in its parameters. Derivatives are the fundamental tools of calculus. Differentiation (the rate of change of a function with respect to a variable in mathematics) (in mathematics, the rate of change of a function with respect to a variable). The use of derivatives is essential in the solution of calculus and differential equation problems. The definition of "derivative" or "taking a derivative" in calculus is finding the "slope" of a certain function. Because it is frequently the slope of a straight line, it should be enclosed in quotation marks. Derivatives are rate of change metrics that apply to almost any function.
a) find the derivatives,
[tex]S(t) = 31t^3 - 501t^2 + 220t + 150\\S'(t) = 3(31t^2) - 2(501t) + 220\\S'(2) = 3(31(2)^2) - 2(501(2)) + 220 = 372\\S'(3) = 3(31(3)^2) - 2(501(3)) + 220 = 327\\S'(4) = 3(31(4)^2) - 2(501(4)) + 220 = 252\\[/tex]
b) To find S(2), S(3), and S''(4), we use the original expression for S(t):
[tex]S(2) = 31(2)^3 - 501(2)^2 + 220(2) + 150 = 662\\S(3) = 31(3)^3 - 501(3)^2 + 220(3) + 150 = 669\\S''(t) = (S'(t))' = 6(31t) - 2(501)\\S''(4) = 6(31(4)) - 2(501) = 264\\[/tex]

240 mins=4 hrs
(i promise its right this time- i bet)
Answer:
c. 80 minutes
Step-by-step explanation:
Some problems give you too much information, and you need to choose only the information you need. The number of pages is not important. Here you only need the time, 4 hours, and the number of assignments, 3.
4 hours × 60 minutes / hour = 240 minutes
240 minutes / 3 assignments = 80 minutes/assignment

Simplify: 516−−√ + 1254−−√ − 38√
ANS : 2√(3 × 43) + √(1254) - √(38)
Let's break down the expression step by step:
Expression: √(516) + √(1254) - √(38)
Step 1: Identify prime factors of each number in the Square roots.
- Prime factors of 516: 2^2 × 3 × 43
- Prime factors of 1254: 2 × 3^1 × 11 × 19
- Prime factors of 38: 2 × 19
Step 2: Simplify the square roots using prime factors.
- √(516) = √(2^2 × 3 × 43) = 2√(3 × 43)
- √(1254) = √(2 × 3 × 11 × 19) (This square root cannot be simplified further.)
- √(38) = √(2 × 19) (This square root cannot be simplified further.)
Step 3: Substitute simplified square roots back into the expression.
- 2√(3 × 43) + √(1254) - √(38)
Since we cannot simplify the square roots of 1254 and 38 further, and there are no common terms to combine, the given expression is already in its simplest form:
Answer: 2√(3 × 43) + √(1254) - √(38)

Sam buys a new tent for $866. He knows that the value of the tent will depreciate 12% each year. How much will it be worth in 3 years? Give your answer to two decimal places.
Answer:
Step-by-step explanation:
If the value of the tent depreciates by 12% each year, then its value at the end of each year is 100% - 12% = 88% of its value at the beginning of the year.
So after the first year, the value of the tent will be:
$866 x 0.88 = $761.28
After the second year, the value of the tent will be:
$761.28 x 0.88 = $670.58
After the third year, the value of the tent will be:
$670.58 x 0.88 = $590.99
Therefore, the tent will be worth $590.99 in 3 years, to two decimal places.
Answer:
After one year, the value of the tent will be worth 100% - 12% = 88% of its original value.
After two years, the value of the tent will be worth 88% - 12% = 77.44% of its original value.
After three years, the value of the tent will be worth 77.44% - 12% = 68.1472% of its original value.
To find out how much the tent will be worth in 3 years, we can use the following formula:
Value after 3 years = original value x (1 - depreciation rate)^number of years
Value after 3 years = $866 x (1 - 0.12)^3 = $518.98
Therefore, the tent will be worth $518.98 in 3 years.
Mrs. Dugan plans to serve
100 barbecue sandwiches at the
company picnic. How many packages
of barbecue buns will she need if buns
come in packages of 83 Packages of 12?
Answer:
For packages of 8: She will need 13 packages
For packages of 12: She will need 9 packages
Step-by-step explanation:
Number of barbecues sandwiches = 100 (given)
For packages of 8 we have, (100/8) = 12 (without the remainder)
We then add one extra package so that the 100 barbecue sandwiches are served.
So, for packages of 8, packages of barbecue buns = 12 + 1 = 13
For packages of 12 we have, (100/12) = 8 (without the remainder)
We then add one extra package so that the 100 barbecue sandwiches are served.
So, for packages of 12, packages of barbecue buns = 8 + 1 = 9
