Answers
Explanation:
1/4 = 0.25
0.25*360 = 90
90 white beans, 360-90 = 270 black beans
The ratio of white to black is 90:270 which fully simplifies to 1:3 after dividing both parts by the GCF 90.
In the past few years, many small businesses have been faced with difficulty keeping their doors open, and in many cases large corporations with cash on hand have come in to take over the companies and their real estate. In such case, a large restaurant chain purchased a small corner tavern with plans to use the name to build a local franchise. The cost of buying the franchise naming rights was four times the cost of buying the physical property. If the total purchase price was $1,250,000, how much did the restaurant chain pay for each individual element of the sale ( naming rights and physical property)?
Answers
The restaurant chain paid $625,000 for the physical property and $2,500,000 for the franchise naming rights, for a total purchase price of $1,250,000.
What is sale?Sale refers to the transfer of ownership of goods or services from one person to another in exchange for money or other consideration.
The total purchase price of the franchise naming rights and physical property was $1,250,000.
To calculate the amount paid for each individual element of the sale, the total purchase price must be divided by the two elements.
The total purchase price of $1,250,000 divided by two elements equals $625,000.
This means that the restaurant chain paid $625,000 for the franchise naming rights and $625,000 for the physical property.
The amount of money paid for the franchise naming rights (four times the cost of buying the physical property) can be calculated by multiplying the cost of the physical property, which is
$625,000/4 .
When the cost of the physical property is multiplied by four, the result is $2,500,000.
This means that the restaurant chain paid $2,500,000 for the franchise naming rights.
In summary, the restaurant chain paid $625,000 for the physical property and $2,500,000 for the franchise naming rights, for a total purchase price of $1,250,000.

A florist currently makes a profit of $20 on each of her celebration bouquets and sells an average of 30 bouquets every week. She noticed that when she reduces the price such that she earns $1 less in profit from each bouquet, she then sells three more bouquets per week. The relationship between her weekly profit, P(x), after x one-dollar decreases is shown in the graph below.
A graph for p of x is a downward open parabola with its vertex at (5, 725) and passes through the points (negative 10, 0), and (20, 0).
Use the graph to complete each statement about this situation.
The maximum profit the florist will earn from selling celebration bouquets is $.
The florist will break-even after one-dollar decreases.
The interval of the number of one-dollar decreases for which the florist makes a profit from celebration bouquets is ( , ).
Answers
Answer:
The maximum profit the florist will earn from selling celebration bouquets is $725.
The florist will break-even after one-dollar decreases when her profit is zero. From the graph, this occurs at x = 10. So the florist will break-even after 10 one-dollar decreases.
The interval of the number of one-dollar decreases for which the florist makes a profit from celebration bouquets is (0, 10). This is because the profit is positive for values of x between 0 and 10, and becomes negative after 10.
Step-by-step explanation:
The Ozzie Chocolate Company is preparing to offer a new product in its candy offerings, the Minty Dark Chocolate Bite bar. Material costs per new candy bar are
$0.25 for chocolate, $0.02 for sugar, and $0.03 for mint flavoring. Labor costs of the new product are approximately $0.15 per bar. Adding a production line devoted to the new candy will cost $250,000 per year.
(a) If the sales price is $1.40 per candy bar, how many must the company make per year in order to break even? Assume that each bar made is sold at full price.
(b) What is the company's profit or loss if they make and sell 270,000 candy bars at the $1.40 price in the first year?
(c) About 20% of the food consumed in the U.S. is imported. Production in many industries has been offshored. What ethical issues do companies face when presented with the decision to move operations?
Answers
Answer:
a) 263,158
b) $164,500
c) Ethical issues companies face when deciding to move operations: job loss for employees, poor working conditions and exploitation of workers, negative environmental impact,...
Step-by-step explanation:
a)
Total cost = (0.25 + 0.02 + 0.03 + 0.15) x + 250,000
Total revenue = 1.40x
Setting the two equations equal to each other and solving for x, we get:
(0.45)x + 250,000 = 1.40x
0.95x = 250,000
x ≈ 263,158
b)
If the company sells 270,000 candy bars at $1.40 each, the total revenue generated is:
270,000 * $1.40 = $378,000
The total cost of producing 270,000 candy bars is:
(0.25 + 0.02 + 0.03 + 0.15) * 270,000 + $250,000 = $213,500
Therefore, the company's profit is:
$378,000 - $213,500 = $164,500
c)
Ethical issues companies face when presented with the decision to move operations: job loss for employees, poor working conditions and exploitation of workers, negative environmental impact,...
suface area of cuboid 9 5 4
Answers
The cuboid in question has a surface area of 202 square units.
We must sum together the areas of all six faces to determine a cuboid's surface area.
The dimensions of the given cuboid are:
length (l) = 9 units
width (w) = 5 units
height (h) = 4 units
The area of each face is given by:
Top and bottom faces:\(lw = 9 * 5 = 45\) square units each
Front and back faces: \(lh = 9 *4 = 36\) square units each
Left and right faces: \(wh = 5 * 4 = 20\) square units each
Therefore, the total surface area of the cuboid is:
\(2(lw + lh + wh) = 2(45 + 36 + 20)\\ = 2(101) \\= 202 \ square \ units\)
Hence, the surface area of the given cuboid is 202 square units.

Prove that
(secx+tanx)² =CSCx+1/CSC x-1
Answers
To prove that (secx+tanx)² = (cscx+1)/(cscx-1), we will start with the left-hand side (LHS) of the equation and simplify it step by step until it matches the right-hand side (RHS) of the equation.
LHS: (secx+tanx)²
Using the trigonometric identities secx = 1/cosx and tanx = sinx/cosx, we can rewrite the LHS as:
LHS: (1/cosx + sinx/cosx)²
Now, let's find a common denominator and simplify:
LHS: [(1+sinx)/cosx]²
Expanding the squared term, we get:
LHS: (1+sinx)² / cos²x
Next, we will simplify the denominator:
LHS: (1+sinx)² / (1 - sin²x)
Using the Pythagorean identity sin²x + cos²x = 1, we can replace 1 - sin²x with cos²x:
LHS: (1+sinx)² / cos²x
Now, let's simplify the numerator by expanding it:
LHS: (1+2sinx+sin²x) / cos²x
Next, we will simplify the denominator by using the reciprocal identity cos²x = 1/sin²x:
LHS: (1+2sinx+sin²x) / (1/sin²x)
Now, let's simplify further by multiplying the numerator and denominator by sin²x:
LHS: sin²x(1+2sinx+sin²x) / 1
Expanding the numerator, we get:
LHS: (sin²x + 2sin³x + sin⁴x) / 1
Now, let's simplify the numerator by factoring out sin²x:
LHS: sin²x(1 + 2sinx + sin²x) / 1
Using the fact that sin²x = 1 - cos²x, we can rewrite the numerator:
LHS: sin²x(1 + 2sinx + (1-cos²x)) / 1
Simplifying further, we get:
LHS: sin²x(2sinx + 2 - cos²x) / 1
Using the fact that cos²x = 1 - sin²x, we can rewrite the numerator again:
LHS: sin²x(2sinx + 2 - (1-sin²x)) / 1
Simplifying the numerator, we have:
LHS: sin²x(2sinx + 1 + sin²x) / 1
Now, let's simplify the numerator by expanding it:
LHS: (2sin³x + sin²x + sin²x) / 1
LHS: 2sin³x + 2sin²x / 1
Finally, combining like terms, we get:
LHS: 2sin²x(sin x + 1) / 1
Now, let's simplify the RHS of the equation and see if it matches the LHS:
RHS: (cscx+1) / (cscx-1)
Using the reciprocal identity cscx = 1/sinx, we can rewrite the RHS:
RHS: (1/sinx + 1) / (1/sinx - 1)
Multiplying the numerator and denominator by sinx to simplify, we get:
RHS: (1 + sinx) / (1 - sinx)
Now, we can see that the LHS and RHS are equal:
LHS: 2sin²x(sin x + 1) / 1
RHS: (1 + sinx) / (1 - sinx)
Therefore, we have proven that (secx+tanx)² = (cscx+1)/(cscx-1).

Answers
The zeros of the function defined by
h(x) = x³ – 4x² – 5x are x = 0, x = 5 and x = -1
What are the zeros of a functionThe zeros of a function, also referred to as roots or x-intercepts, occur at x-values where the value of the function is 0. It is simply the values of x when f(x) is equal to 0.
For x = 0, we substitute 0 for x in the function h(x);
h(0) = (0)³ - 4(0)² - 5(0)
h(0) = 0
For x = 1, we substitute 1 for x in the function h(x);
h(1) = (1)³ - 4(1)² - 5(1)
h(1) = 1 - 4 - 5
h(1) = -8
For x = -5, we substitute -5 for x in the function h(x);
h(-5) = (-5)³ - 4(-5)² - 5(-5)
h(-5) = -125 - 100 +25
h(-5) = -200
For x = 5, we substitute 5 for x in the function h(x);
h(5) = (5)³ - 4(5)² - 5(5)
h(5) = 125 - 100 - 25
h(5) = 0
For x = -1, we substitute -1 for x in the function h(x);
h(-1) = (-1)³ - 4(-1)² - 5(-1)
h(-1) = -1 - 4 + 5
h(-1) = 0
Therefore, the values of x that makes the function h(x) = x³ – 4x² – 5x equal to zero are; 0, 5, and -1, they are the zeros of the function h(x).

A rectangular portrait is 1 yard wide and 2 yards high. It costs $30.00 per yard to put a gold frame around the portrait ¿how much will the frame cost?
Answers
The frame for the rectangular portrait will cost $180.00.
The rectangular portrait has a width of 1 yard and a height of 2 yards. To calculate the perimeter of the portrait, which represents the length of frame required, we can use the formula:
Perimeter = 2 * (Width + Height)
Substituting the values, we have:
Perimeter = 2 * (1 yard + 2 yards) = 2 * 3 yards = 6 yards
The cost of the frame is given as $30.00 per yard. To calculate the total cost of the frame, we multiply the length of the frame (in yards) by the cost per yard:
Frame Cost = Perimeter * Cost per yard = 6 yards * $30.00/yard = $180.00
Therefore, the frame for the rectangular portrait will cost $180.00.

d
\(P(A_4) = 0.004\)
e
\(P(A_5) = 0.0002\)
Step-by-step explanation:
From the question we are told that
The number of cards selected is n = 7
Generally in a standard deck of cards
The total number of cards is N = 52
The number of hearts is h = 13
The number of diamonds is d = 13
The number of spade is s = 13
The number of Ace is a = 4
The number of kings is k = 4
Considering question a
The number of ways to selected 5 hearts out of the 13 hearts is mathematically represented as
\(G = ^{13}C_5\)
Here C means combination so
The number of cards that is not hearts is 52 - 13 = 39
Generally the number of ways of selecting the reaming 2 cards is
\(H = ^{39}C_2\)
Generally the number of ways to select the 7 cards from the 52 deck of cards is
\(V = ^{52}C_7\)
Generally the probability that exactly 5 of the 7 cards are hearts is mathematically represented as
\(P(A_1) = \frac{G * H}{V}\)
=> \(P(A_1) = \frac{^{13}C_5 * ^{39}C_2}{^{52}C_7}\)
=> \(P(A_1) = 0.007\)
Considering question b
The number of ways to selected 3 diamonds out of the 13 diamonds is mathematically represented as
\( B = ^{13} C_3 \)
The number of ways to selected 3 hearts out of the 13 hearts is mathematically represented as
\(K = ^{13}C_3\)
The number of cards that is not hearts or diamond is 52 - (13 +13) = 26
Generally the number of ways of selecting the reaming 1 cards is
\(M = ^{26}C_1\)
Generally the probability that there are 3 hearts and 3 diamonds is
\(P(A_2) = \frac{B * K * M}{V}\)
=> \(P(A_2) = \frac{^{13}C_3 * ^{13}C_3 * ^{26}C_1}{^{52}C_7}\)
=> \(P(A_2) = 0.016\)
Considering question c
The number of ways to selected 1 spade out of the 13 spade is mathematically represented as
\(J = ^{13}C_1\)
Generally the probability that there are 3 hearts, 3 diamonds and 1 spade is
\(P(A_3) = \frac{B * K * J}{V}\)
=> \(P(A_3) = \frac{^{13}C_3 * ^{13}C_3 * ^{13}C_1}{^{52}C_7}\)
=> \(P(A_3) = 0.008\)
Considering question d
The number of ways to selected 2 Aces out of the 4 Aces is mathematically represented a
\(U = ^{4}C_2\)
The number of ways to selected 2 Kings out of the 4 Kings is mathematically represented a
\(R = ^{4}C_2\)
The number of cards that is not Aces or Kings is 52 - (4 +4) = 44
Generally the number of ways of selecting the reaming 3 cards is
\(S = ^{44}C_3\)
Generally the probability that there are 2 Aces and 2 Kings is
\(P(A_4) = \frac{U * R * S}{ V}\)
=> \(P(A_4) = \frac{ ^{4}C_2 * ^{4}C_2 * ^{44}C_3}{ ^{52}C_7}\)
=>\(P(A_4) = 0.004\)
Considering question e
The number of ways to selected 3 Kings out of the 4 Kings is mathematically represented a
\(P = ^{4}C_3\)
Generally the number of ways of selecting the reaming 2 cards is
\(Q = ^{44}C_2\)
Generally the probability that there are 2 Aces and 3 Kings is
\(P(A_5) = \frac{U * P * Q }{V}\)
=> \(P(A_5) = \frac{ ^{4}C_2 * ^{4}C_3 * ^{44}C_2 }{^{52}C_7}\)
=> \(P(A_5) = 0.0002\)

y = (x1 + x2 + x3 + x4 + x5) / 5
since y = 85:
(x1 + x2 + x3 + x4 + x5) / 5 = 85
A photographer wants to print a photograph and two smaller copies on a rectangular sheet of paper. The larger photograph and the smaller photographs are in proportion. The larger photograph has a width of 4 inches and a length of 6 inches. Point A and point B are the midpoints of the sides of each rectangle. Here are two possible
ways the photographs can be arranged:
(Note: Diagrams are not drawn to scale.)
Part 1:
Find the measurements of the small photographs for each diagram. Show your calculations and label the meaning of all numbers.
Answers
3 Since the smaller photo has a decrement ratio of roughly $3 to $6, it would be half as tall in Diagram 1, making it 2 inches wide. For Diagram 1, the height is 6 for the usual photo, therefore each one has to be 3 inches high.
What is ratio?A ratio in math displays how many times one number is contained in another. The ratio of oranges to lemons, for instance, is eight to six if there are eight oranges and six lemons in a bowl of fruit. The proportions of oranges to the overall amount of fruit are 8:14 for oranges and 6:8 for lemons, respectively. When the second number in the ordered pair, b, is not equal to 0, the ratio is expressed as a/b. An equation in which two ratios are made equal is known as a percentage. Comparing two numbers by dividing them is how ratios work. Your formula would be A/B if you were contrasting one data point (A) with another data point (B).To learn more about ratio, refer to:
