Answer:

12 cubic units

Step-by-step explanation:

Since 1 cube is equal to 1 cubic unit and there are 12 cubes in total, this means the volume is 12 cubic units.

Answer: See below

Step-by-step explanation:

First, we will use the conversions that you provided to find how many feet are in 3 miles. Since we know that one mile = 5,280 feet, all we have to do is multiply that number by 3 to find the conversion.

5,280 * 3 = 15,840 feet

Now, we can use the value found above to find how many inches are in 3 miles. We know that 12 inches are in one foot, so we have to multiply 12 by 15,840. This equals 190,080 inches.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

Given;

The video game usually costs 39.99

Sale off= 20%

Now,

Let the 20% be x

x*100/39.99=20

x=20*39.99/100

x=799.8/100

x=7.998

After off;

=39.99-7.998

=31.992

Therefore, the value after 20 percent off will be $31.992

Step-by-step explanation:

solving the inequality

- 13t ≤ 78

divide both sides by - 13, reversing the symbol as a result of dividing by a negative quantity.

t ≥ - 6

this means that any value of t greater than 6, including 6, is a solution.

listing the solutions from - 10 through to 10 that are solutions when substituted for t

- 6, - 5, - 4, - 3, - 2, - 1, 0, 1, 2, 3, 4, 5, 6

The general solution of the differential equation is [tex]y = \frac{\pm Ce^{3e^{-x}} + 1}{x}[/tex], where C is an arbitrary constant.

To find the general solution, we can first try separating the variables by dividing both sides of the equation by x²:

The given differential equation is (x²)dy/dx + (x²)y = [tex]6xe^{-x[/tex]

[tex]\frac{dy}{y} = 6e^{-x} \frac{dx}{x^2}[/tex]

Integrating both sides with respect to their respective variables:

[tex]\int (dy/y) = \int 6e^{-x} \frac {dx}{x^2} + C[/tex]

ln [tex]|y| = \frac{-3e^{-x} - 1}{x} + C[/tex]

Exponentiating both sides:

[tex]|y| = \frac{Ce^{3e^{-x}} - 1}{x}[/tex]

where C is an arbitrary constant.

Since the solution for y is not unique, we need to determine the sign of y. To do this, we can analyze the initial conditions or the nature of the problem. If the initial conditions indicate that y is positive, then [tex]y = \frac{\pm Ce^{3e^{-x}} + 1}{x}[/tex]. If the initial conditions indicate that y is negative, then [tex]y = \frac{\pm Ce^{3e^{-x}} + 1}{x}[/tex].

Therefore, the general solution of the differential equation is [tex]y = \frac{\pm Ce^{3e^{-x}} + 1}{x}[/tex], where C is an arbitrary constant.

If everyone shakes hands with everyone else in a group of 20, the number of handshakes take place is 210.

In a group of 20 people, if everyone shakes hands with everyone else, the number of handshakes that take place is equal to the sum of the first 20 positive integers, which can be found using the formula for the sum of an arithmetic series:

= n (n + 1)/ 2

= (20 * 21) / 2 = 210

To understand why this is the case, consider that each person shakes hands with 19 other people, so there are a total of 20 * 19 = 380 handshakes. However, each handshake is counted twice (once for each person involved), so we need to divide the total number of handshakes by 2 to get the actual number of unique handshakes. Hence, the answer is 380 / 2 = 210.

The number of children is 379 and the number of the adults is 339.

A system of equations in algebra consists of two or more equations and looks for common answers to the equations. "A collection of equations fulfilled by the same set of variables is called a system of linear equations."

Let us suppose the number of children = C, and the number of adults = A.

Given that, 718 people used the public swimming pool:

C + A = 718 people

The cost for one child is 1.25 for children, then the cost for C child is: 1.25C

The cost for one adult is 2.00 for adults, then the cost for A adults is: 2A

The receipts for admission totaled 1151.75:

1.25C + 2A = 1151.75

The two equations are:

C + A = 718

1.25C + 2A = 1151.75

For the first equation we can write:

C + A = 718

C = 718 - A

Substitute the value of C in second equation:

1.25(718 - A) + 2A = 1151.75

897.5 - 1.25A + 2A = 1151.75

0.75A = 254.25

A = 339

Substituting the value of A in the first equation we have:

C + A = 718

C + 339 = 718

C = 379

Hence, the number of children is 379 and the number of the adults is 339.

The probability that the sample has one democrat, one republican and one independent is 0.1518.

Probability is a mathematical concept that describes the likelihood of an event occurring. It is a value between 0 and 1, where 0 indicates that an event is impossible, 1 indicates that an event is certain, and values between 0 and 1 indicate the degree of uncertainty or likelihood of an event occurring.

The total number of ways to select 3 voters out of 40 can be determined using the combination formula:

C(n, k) = n! / [k!(n - k)!]

where n is the total number of elements in the set and k is the number of elements to be selected.

C(40,3) = 40! / [3!(40 - 3)!] = 9880

The number of ways to select 1 Democrat, 1 Republican and 1 Independent is as follows:

C(20, 1) x C(15, 1) x C(5, 1) = 20 x 15 x 5 = 1500

So, the probability of selecting 1 Democrat, 1 Republican and 1 Independent in a sample of 3 voters is 1500 / 9880 = 0.151821, which rounded to four decimal places is 0.1518.

It's difficult for me to determine which recent decisions have been made using these strategies without more context about the specific situation. However, I can provide general information about how each strategy may be used and what factors may influence the decision-making process.

Spontaneity: This strategy may be used in situations where time is of the essence, and there is not enough time to weigh all options. The individual may also be impulsive or lack the ability to plan ahead.

Compliance: This strategy may be used in situations where the individual values the opinions of others over their own, or they may not want to upset their family, teachers, or friends.

Procrastination: This strategy may be used when the individual is overwhelmed by the decision-making process, and they are unsure of what choice to make. They may also be afraid of making the wrong choice.

Agonizing: This strategy may be used when the individual wants to make sure that they are making the best decision, and they want to gather as much information as possible. This can lead to paralysis by analysis, and they may not make a decision at all.

Desire: This strategy may be used when the individual wants to achieve a specific outcome, and they are willing to take a risk to do so. They may also be motivated by a sense of adventure.

Avoidance: This strategy may be used when the individual wants to avoid a negative outcome, and they are willing to make a decision based on that.

Security: This strategy may be used when the individual wants to make a decision that will not upset others or involve risk. They may also be motivated by a sense of stability.

Synthesis: This strategy may be used when the individual wants to choose an option that will probably be successful and which they like the best. They may also have a good sense of what they want and what is best for them.

These are general information, the hardest part of the decision-making process for an individual may vary depending on the situation, the options available, and their personal preferences. Furthermore, there may be more than one solution to a problem, and the best one depends on the individual's preferences, resources, and the context of the problem.

It has n-k basic variables. The basic variables are the variables that are not free variables, and they are the ones that can be solved for as part of the general solution.

The general solution of a system of m linear equations in n variables contains k free variables. This means that there are k variables that have no restrictions and can take on any value. The remaining n-k variables are the basic variables, which are the ones that can be solved for as part of the general solution. The basic variables are the ones that have restrictions and need to be solved for in order to determine the solution of the system. In other words, the number of basic variables is equal to the number of variables minus the number of free variables. Thus, the general solution of the system has n-k basic variables.

The surface area of the right triangular prism is 108 ft²

An equation is an expression that shows the relationship between two or more numbers and variables.

The surface area of a three dimensional figure is gotten by individually adding each of their respective areas of the surfaces.

From the net and the diagram shown:

A = 5 feet, B = 4 feet, D = 3 feet and C = 8 feet

Surface area = area of triangle 1 + area of triangle 2 + area of rectangle 1 + area of rectangle 2 + area of rectangle 3

Surface area = (0.5 * B * D) + (0.5 * B * D) + (A * C) + (C * B) + (D * C)

Substituting:

Surface area = (0.5 * 4 * 3) + (0.5 * 4 * 3) + (5 * 8) + (4 * 8) + (3 * 8) = 108 ft²

The lengths of the diagonals of QRST is 14units.

In a rectangle, the diagonals are equal in length and bisect each other at 90 degrees. This means that the diagonals divide the rectangle into four congruent right triangles.

Since the diagonals of a rectangle are of equal length. then

QS = RT

4x + 2 = 5x - 1

Simplify and solve for the value of x.

4x + 2 = 5x - 1

x = 3

Substitute the value of x in any of the expression for the length of the diagonal.

One alternative method for correcting the external effect between players is the Coasian bargaining solution. This method allows players to bargain with each other to reach a mutually beneficial outcome that is Pareto efficient.

Another alternative method is a Pigouvian tax. Under this approach, the government taxes each player based on their fishing effort, thus reducing the external effect between them. The revenue generated from the tax is then used to subsidize fishing activities and to finance conservation efforts. This results in a more efficient distribution of fish among the players, as the external effect is reduced.  

Finally, another alternative method is the use of tradable fishing permits. Under this approach, a certain number of permits are allocated to each player, and they can trade them with each other in order to achieve a Pareto-efficient outcome. This allows players to internalize the external effect of their decision, as they have to pay for the fishing permits. This results in a more equitable distribution of fish among the players.

Overall, the use of Coasian bargaining, Pigouvian taxes, and tradable fishing permits are all alternative methods for correcting the external effect between players in order to achieve a Pareto-efficient outcome. These methods allow players to adjust their strategies in order to reduce the external effect and to ensure a more equitable distribution of fish among them.
