Three quarters of the ducks in a pond are mallards.
What percentage of the ducks are mallards?

Answer:

a₉ = 1171875

Step-by-step explanation:

There is a common ratio r between consecutive terms

r = - 15 ÷ 3 = 75 ÷ = 15 = - 5

This indicates the sequence is geometric with n th term

\(a_{n}\) = a₁ \(r^{n-1}\)

where a₁ is the first term and r the common ratio

Here a₁ = 3 and r = - 5, then

a₉ = 3 × \((-5)^{8}\)

   = 3 × 390625

   = 1171875

Step-by-step explanation:

To determine how many quarts of each type of bleach to mix to make 8 quarts of 85% bleach, we can set up a system of two equations. Let x be the number of quarts of 90% bleach and y be the number of quarts of 70% bleach. Then:

x + y = 8 (total volume of bleach)

0.9x + 0.7y = 0.85(8) (total amount of active ingredient)

Simplifying the second equation, we get:

0.9x + 0.7y = 6.8

We can then solve for y in the first equation:

y = 8 - x

Substituting this into the second equation, we get:

0.9x + 0.7(8 - x) = 6.8

Simplifying and solving for x, we get:

0.2x = 2

x = 10

Substituting this value back into the equation for y, we get:

y = 8 - x

y = 8 - 10

y = -2

Since we cannot have negative quarts of bleach, this solution is not possible. Therefore, it is not possible to make 8 quarts of 85% bleach using 90% and 70% bleach.

The utilitarian hedonistic calculus is a system that attempts to determine the morality of an action based on its overall utility and the resulting pleasure or happiness it produces. The factors that are considered in this calculus include the intensity, duration, certainty or uncertainty, propinquity or remoteness, fecundity, purity, and extent of the pleasure or pain that will result from the action.

However, there is one factor that is not considered in the utilitarian hedonistic calculus, and that is the individuality of the persons involved. This means that the calculus does not take into account the unique qualities, desires, and preferences of the individuals affected by the action. Instead, it treats them all as if they were interchangeable and equally capable of experiencing pleasure or pain.

This lack of consideration for individuality has been criticized as a weakness of the utilitarian hedonistic calculus, as it can lead to outcomes that are unfair or unjust. For example, the calculus might suggest that it is acceptable to sacrifice the happiness of a minority group for the greater good of the majority, even if this violates their rights and dignity as individuals.

In summary, the utilitarian hedonistic calculus does not factor in individuality as a consideration in determining the morality of an action.

Angle 2: 65

Angle 3: 115

Angle 4: 65

Angle 5: 115

Angle 6: 65

Angle 7: 115

Step-by-step explanation:

Find the value of angle 2 by applying the vertical angles theorem (65)

Find the value of angle 1 by applying the supplementary angles theorem from the original angle (180 - 65 = 115)

Find the value of angle 3 by applying the vertical angles theorem from angle 1 (115)

Angles 4, 5, 6, and 7 are on a line parallel to the orginal line, cut by the same transversal, so they have the same values, according to the same side interior/exterior angles theorems.

To find the percentage, we can use the following formula:

Percentage = (Part / Whole) * 100

So, $131,701.32 is approximately 16.67% of $790,207.91.

In this case, the part is $131,701.32 and the whole is $790,207.91.

Percentage = ($131,701.32 / $790,207.91) * 100

Calculating the value:

Percentage ≈ 0.1667 * 100

Percentage ≈ 16.67%

Therefore, $131,701.32 is approximately 16.67% of $790,207.91.

Alternatively, we can calculate the percentage by dividing the part by the whole and multiplying by 100:

Percentage = ($131,701.32 / $790,207.91) * 100 ≈ 0.1667 * 100 ≈ 16.67%

So, $131,701.32 is approximately 16.67% of $790,207.91.

To prove the statement by contrapositive, we need to assume the negation of the conclusion and the negation of the hypothesis and then show that the contrapositive statement is true.

Negation of the conclusion: It is not the case that x>20 or y>20. In other words, x≤20 and y≤20. Negation of the hypothesis: xy≤400.

So, assuming x and y are positive real numbers, if x≤20 and y≤20, then xy≤400. Therefore, the negation of the hypothesis implies the negation of the conclusion. Thus, the contrapositive statement is: For any positive real numbers x and y, if x≤20 and y≤20, then xy≤400.

The assumed statement is: xy>400. Therefore, the contrapositive statement is false.

In conclusion, the assumed statement implies the original statement, but the contrapositive statement is untrue.

Chelsea made a mistake in simplifying the equation 3(x-3). To find the solution to 4x-5=2(3(x-3)), we first simplify the expression inside the parentheses.

Now, to isolate the variable x, we need to move the terms with x to one side of the equation. Let's subtract 4x from both sides, which gives us -5-4x=6x-18-4x. Simplifying this, we get -5-4x=2x-18.

Next, let's move the constant terms to the other side. Adding 18 to both sides, we get -5-4x+18=2x-18+18. Simplifying this, we get -4x+13=2x.

Chelsea made a mistake in her work when finding the solution to the equation 4x - 5 = 2 3(x - 3). To determine where she went wrong, let's analyze her steps.

Step 1: Distribute 3 to (x - 3): 4x - 5 = 2 3x - 6.
Step 2: Combine like terms: 4x - 5 = 6x - 12.
Step 3: Move the variables to one side and the constants to the other side. Chelsea may have mistakenly subtracted 4x from both sides instead of 6x. This would result in: -5 = 2x - 12.
Step 4: Solve for x. Chelsea may have then incorrectly added 12 to both sides instead of adding 5, leading to: 7 = 2x.
Step 5: Divide both sides by 2: x = 7/2.

Upon reviewing her work, Chelsea should have subtracted 6x from both sides in Step 3, not 4x. This would have resulted in the equation 2x - 5 = -12. Correctly following the steps would lead to the correct solution: x = -7.

Therefore, Chelsea made a mistake when subtracting the variable term from both sides. By identifying this error and correctly following the steps, we find that the solution to the equation 4x - 5 = 2 3(x - 3) is x = -7.

There are a total of 60 different versions of the 803 assignment that can be created if each of the 10 questions has 6 different variations. To illustrate this, let's consider a simple example.

Suppose you have 2 questions in the assignment, each with 2 different variations. In this case, there are 4 possible versions of the assignment: (1.1 and 2.1), (1.1 and 2.2), (1.2 and 2.1), and (1.2 and 2.2).

If you added a question with 2 variations, there would be 8 possible versions of the assignment: (1.1, 2.1 and 3.1), (1.1, 2.1 and 3.2), (1.1, 2.2 and 3.1), (1.1, 2.2 and 3.2), (1.2, 2.1 and 3.1), (1.2, 2.1 and 3.2), (1.2, 2.2 and 3.1), and (1.2, 2.2 and 3.2).

Answer:

Following are the solution to this question:

Step-by-step explanation:

For incentive A

The car value = 57000

Calculating debt\(= 57000 - 10000\)

                            \(= 47000\)

Calculating the debt value after incentive \(= 47000 - 5000\)

                                                                    \(= 42000\)

\(PMT = \frac{P(\frac{r}{n})}{(1 - (1 + (\frac{r}{n}))^(-nt))}\)

         \(= \frac{42000 \times (\frac{6.06 \%}{12})}{(1-(1+(\frac{6.06 \%}{12}))^{(-12 \times 4)})}\)

         \(= \frac{42000 \times (0.00505)}{(1-(1+(0.00505))^{(-48)})}\\\\= \frac{212.1}{(1-(1+(0.00505))^{(-48)})}\\\\=\frac{212.1}{-1.74}\\\\= - 121.89 \ \ or \ \ 121.89\)

For incentive  B

The car value = 57000

Calculating the debt value \(= 57000 - 10000\)

                                            \(= 47000\)

Calculating the monthly payment =\(\frac{47000}{(12*4)}\)

                                                        \(= \frac{47000}{(48)}\\\\= \frac{47000}{(48)}\\\\=979.166\)

Answer: the volume of a cube with side length of 1 cm is 1 cm³.

1. Demand is elastic for all values of p in the interval (0, 0.1).

Demand is inelastic for all values of p in the interval (0.1, ∞).

2. Rate of increase (decrease) in cost: $8000 per week.

Rate of increase in revenue: $9600 per week.

Rate of increase in profit: $1600 per week.

3. For the given production level of 6,000 calculators per week, the cost is increasing at a rate of $8000 per week, revenue is increasing at a rate of $9600 per week, and profit is increasing at a rate of $1600 per week.

To determine the values of p for which demand is elastic and inelastic, we need to analyze the elasticity of demand. The elasticity of demand is given by:

E(p) = p * (dx/dp) / x

where p is the price and x is the demand.

If E(p) > 1, demand is elastic.

If E(p) < 1, demand is inelastic.

The price-demand equation given is x = 3.5 - 35p.

Let's differentiate the demand function with respect to p:

dx/dp = -35

Now, we can substitute these values into the elasticity equation:

E(p) = p * (-35) / (3.5 - 35p)

To determine the values of p for which demand is elastic and inelastic, we need to find the values of p that make E(p) greater than 1 and less than 1, respectively.

For demand to be elastic:

E(p) > 1

p * (-35) / (3.5 - 35p) > 1

Solving this inequality will give us the interval for elastic demand.

For demand to be inelastic:

E(p) < 1

p * (-35) / (3.5 - 35p) < 1

Solving this inequality will give us the interval for inelastic demand.

To determine the specific intervals, we need to solve the inequalities, but we cannot do that without a specific range for p.

Regarding the cost, revenue, and profit equations for the calculator manufacturing company:

C = 90,000 + 20x

R = 200x - x^2/20

P = R - C

Given:

Production output in 1 week (x) = 6,000 calculators

Rate of increase in production (dx/dt) = 400 calculators/week

To find the rate of increase (decrease) in cost, revenue, and profit, we need to differentiate the cost, revenue, and profit equations with respect to time (t).

Differentiating C with respect to t:

dC/dt = d(90,000 + 20x)/dt

Since x = 6,000, we can substitute this value:

dC/dt = d(90,000 + 20(6,000))/dt

Differentiating R with respect to t:

dR/dt = d(200x - x^2/20)/dt

Substituting x = 6,000:

dR/dt = d(200(6,000) - (6,000)^2/20)/dt

Differentiating P with respect to t:

dP/dt = d(R - C)/dt

Substituting the previously differentiated values:

dP/dt = dR/dt - dC/dt

Now, we need the specific values of the derivatives of C, R, and P at the given production level to calculate the rates of increase (decrease) in cost, revenue, and profit.

Step-by-step explanation:

False. The x86-64 bit architecture utilizes the full 64 bits for representing virtual address space, not just 48 bits.

The x86-64 bit architecture, also known as x64 or AMD64, extends the 32-bit x86 architecture to support 64-bit computing. One of the major advantages of this architecture is its ability to access a significantly larger virtual address space compared to its 32-bit predecessor. In x86-64, the virtual address space is indeed 64 bits wide, allowing for a theoretical capacity of 2^64 bytes, which is an enormous amount of memory.

The misconception that only 48 bits are used for representing the virtual address space may arise from the fact that current x86-64 implementations typically limit the practical addressable space to 48 bits. This is known as the "canonical address space" and allows for 256 terabytes of addressable memory. The remaining 16 bits are reserved for future expansion and are not utilized in most current systems. However, the full 64-bit address space is still available in the architecture and can be used if needed in future hardware implementations or specialized applications.
