The width of the rectangle is 2 units when length of the rectangle is 10 units.
As per the given data:
The length of a rectangle varies inversely with its width.
The length of the rectangle is 5 units when its width is 4 units
The length of the rectangle when its width is 10 units
Here we have to determine the width of a rectangle.
Let l be the length and w be the width of the rectangle.
Now, from the given direction, we have
[tex]$l=\frac{k}{w}[/tex]
Substitute l = 5 units, w = 4 units, to find the constant k
5 = [tex]$\frac{k}{4}[/tex]
k = 20 units
Now, we have to find the width of the rectangle when l = 10 units
10 = [tex]$\frac{20}{w}[/tex]
w = [tex]$\frac{20}{10}[/tex]
w = 2 units.
Therefore the width of the rectangle is 2 units.

find the general solution of the given differential equation. (x 1) dy dx (x 2)y = 6xe−x
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.

Paul wins 1500 metres in 4,67minute (a) Estimate his average speed in metres per minute (b) Use calculator to find his actual average speed in metres per minutes
Answer: See below
Step-by-step explanation:
A) The best way to estimate average speed is to make sure that each number is a whole number (with no decimals). This will make division much easier. The number of meters is already a whole number, but to make the number of minutes a whole number, we must round. Because the number after the decimal is greater than 5, that means we will round up, making the value of minutes 5. Now we can estimate 1500 metres/5 minutes = 300 metres/minute
As a little rounding tip, you can use this mnemonic: 4 and below, let it go (round down). 5 and above, give it a shove (round up)!
B) To do this part, we can simply plug the following into the calculator:
1500 metres/4.67 minutes = 321.2 metres per minute

P varies inversely as Q and P = 6 when Q = 24. find
a. Q when P = 8
b. P when Q=16
Answer:
Step-by-step explanation:
P = k/Q where k is a constant.
P is 6 when Q is 24, so:
6 = k / 24
k = 6*24 = 144
so, the relation is P = 144/Q.
a. When P = 8,

name and briefly explain at least one alternative method for correcting the external effect that exists between the players. explain how the method would work to achieve a pareto efficient outcome and what effect it would have on the distribution of fish. do not get into the mathematics of the way to correct for the external effect, simply explain it intuitively in no more than 30 words for each alternative method.
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.

consider a group of 20 people. if everyone shakes hands with everyone else, how many handshakes take place?
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.

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.

The number of children is 379 and the number of the adults is 339.
What is system of equations?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.

suppose that the general solution of a system of m linear equations in n variables contains k free variables. how many basic variables does it have? explain your answer.
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.

Charlotte is going to drive from her house to City A without stopping. An equation that determines Charlotte's distance from City At hours after leaving her house is D = -30t +300. What is the y-intercept of the equation and what is its interpretation in the context of the problem?
The y-intercept of the equation D = -30t + 300 is 300.
What is the y-intercept of the equation?
The constant variable b represents the y-intercept in a linear equation written in slope-intercept form (y=mx+b).
The given equation is D = -30t +300.
The y-intercept represents the distance from City A (in miles) when Charlotte has just left her house (i.e. when t = 0). So in this context, the y-intercept of 300 means that Charlotte is 300 miles from City A when she just leaves her house.
Hence, The y-intercept of the equation D = -30t + 300 is 300.

How to find the percentage from the total value?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

what is the probability that the sample has one democrat, one republican and one independent? express your final answer as a decimal and round to four decimal places.
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.
