suppose that there are two types of tickets to a show: advance and same-day. advance tickets cost and same-day tickets cost . for one performance, there were tickets sold in all, and the total amount paid for them was . how many tickets of each type were sold?
100 same-day tickets were sold for the cost using equation.
To solve this problem, we can use a system of two equations with two variables. Let x be the number of advance tickets sold and y be the number of same-day tickets sold. Then we have:
x + y = 600 (equation 1: total number of tickets sold)
50x + 30y = 28000 (equation 2: total amount paid for tickets)
We can solve for x and y by using elimination or substitution. Here's one way to do it using substitution:
From equation 1, we have y = 600 - x. Substitute this into equation 2:
50x + 30(600 - x) = 28000
Simplify and solve for x:
50x + 18000 - 30x = 28000
20x = 10000
x = 500
So 500 advance tickets were sold. To find the number of same-day tickets, we can substitute x = 500 into equation 1:
500 + y = 600
y = 100
So 100 same-day tickets were sold.

what are the effects of cross-linking in polymers?
In addition to decreasing , solubility, and permeability, cross-linking improves polymer strength, stiffness, and temperature resistance.
The process of creating chemical linkages between polymer molecules to form a three-dimensional network is known as cross-linking. The polymer is stronger and more rigid thanks to this network of molecules, which also boosts its resistance to heat and chemicals. In addition to increasing the polymer's durability and resistance to environmental changes, cross-linking also decreases the polymer's flammability, solubility, and permeability. The polymer becomes more stable and less prone to deformation as a result of cross-linking, which also raises the melting point of the polymer. A polymer's characteristics can be modified by cross-linking to fit the needs of certain applications. For instance, cross-linking might be to boost a polymer's strength to satisfy. For example, cross-linking can be employed to make a polymer stronger to fulfil the demands of a particular application or less flammable to make it safer to use. In a variety of sectors, cross-linking is a crucial component of polymer chemistry and polymer engineering.

The purchased cost of a 5-m3 stainless steel tank in 1995 was $10,900. The 2-m-diameter tank is cylindrical with a flat top and bottom. If the entire outer surface of the tank is to be covered with 0.05-m-thickness of magnesia block, estimate the current total cost for the installed and insulated tank. The 1995 cost for the 0.05-m-thick magnesia block was $40 per square meter while the labor for installing the insulation was $95 per square meter.
The estimated current total cost for the installed and insulated tank is $12,065.73.
The first step is to calculate the surface area of the tank. The surface area of a cylinder is calculated as follows:
surface_area = 2 * pi * r * h + 2 * pi * r^2
where:
r is the radius of the cylinder
h is the height of the cylinder
In this case, the radius of the cylinder is 1 meter (half of the diameter) and the height of the cylinder is 1 meter. So the surface area of the tank is:
surface_area = 2 * pi * 1 * 1 + 2 * pi * 1^2 = 6.283185307179586
The insulation will add a thickness of 0.05 meters to the surface area of the tank, so the total surface area of the insulated tank is:
surface_area = 6.283185307179586 + 2 * pi * 1 * 0.05 = 6.806032934459293
The cost of the insulation is $40 per square meter and the cost of labor is $95 per square meter, so the total cost of the insulation and labor is:
cost = 6.806032934459293 * (40 + 95) = $1,165.73
The original cost of the tank was $10,900, so the total cost of the insulated tank is:
cost = 10900 + 1165.73 = $12,065.73
Therefore, the estimated current total cost for the installed and insulated tank is $12,065.73.

Which is the graph of f(x) = 2(3)x?
Answer:
The last graph.
Hope this helps.
I'm assuming the equation should be \(f(x) = 2(3)^x\)
If so, then plug in x = 1 to find that
\(f(x) = 2(3)^x\\\\f(1) = 2(3)^1\\\\f(1) = 2(3)\\\\f(1) = 6\\\\\)
Showing the point (x,y) = (1,6) is on the curve. Only choice A reflects this. So choice A is the answer.
Choices B,C, and D can be ruled out. For instance, with choice B, plugging in x = 2 leads us to get
\(f(x) = 2(3)^x\\\\f(2) = 2(3)^2\\\\f(2) = 2(9)\\\\f(2) = 18\\\\\)
Indicating that (2,18) is on the curve instead of (2,12). This shows choice B is not a a valid answer. Similar situations will happen with C and D.

What is system of equation?simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution. A group of two or more equations that share the same variables is known as a system of equations. A set of values for a variable that simultaneously satisfy each equation is the solution to a system of equations. When there are multiple unknowns and there is sufficient data to set up equations in those unknowns, systems of equations are used to solve applications. In general, we need sufficient information to construct equations in the n unknowns.

For what value of k, the following system of equations kx+2y=3, 3x+6y=10 has a unique solution ?
The given system of equations to have a Unique solution, the value of k must be any real number except 1 (k ≠ 1).
The value of k for which the given system of equations has a unique solution, we can use the concept of determinants. The system of equations is as follows:
kx + 2y = 3 -- (1)
3x + 6y = 10 -- (2)
To have a unique solution, the determinant of the coefficients of x and y must not be zero.
The determinant of the coefficient matrix for the system is:
D = | k 2 |
| 3 6 |
By calculating the determinant, we have:
D = (k * 6) - (2 * 3)
D = 6k - 6
For the system to have a unique solution, the determinant D must not equal zero.
6k - 6 ≠ 0
Simplifying the inequality:
6k ≠ 6
Dividing both sides by 6:
k ≠ 1
Therefore, for the given system of equations to have a unique solution, the value of k must be any real number except 1 (k ≠ 1).
In other words, if k is not equal to 1, the system of equations will have a unique solution. If k is equal to 1, the system will either have infinitely many solutions or no solution.

Answer:
x = 7
Step-by-step explanation:
We can identify the figure formed by 2 radii, (6x - 3), and (3x + 18) as a kite because it is a quadrilateral symmetric around a center line.
The radii sides are congruent, and therefore, the other two sides must be congruent as well. So, we can solve for x by equation (6x - 3) and (3x + 18).
\(6x - 3= 3x + 18\)
↓ subtracting 3x from both sides
\(3x - 3= 18\)
↓ adding 3 to both sides
\(3x = 18 + 3\)
\(3x = 21\)
↓ dividing both sides by 3

Answer:
This one is tricky! Let x be any integer. We can make any other integer we want by taking Ax + B, where A and B are integers too. The square of this integer is than (Ax+B)2. When expanded, this comes out to
A2x2 + 2ABx + B2. We've now made an expression which is the square of an integer for all integers x!
Now, we can set the coefficients of powers of x in the problem and in A2x2 + 2ABx + B2 equal to eachother.
A2 = a2
2AB = c
B2 = b2
Since a is positive, a = A, if A is positive. If A is negative, a = -A (or A = -a). The same logic leads to
b = B, if B is positive. If B is negative, b = -B (or B = -b).
Since c is positive, we know that A and B are either both positive or both negative. This leads to 2 cases:
Case 1: A is positive, B is positive. Then A = a, B = b, and
c = 2ab.
Case 2: A is negative, B is negative. Then A = -a, B = -b, and
c = 2(-a)(-b) = 2ab.
Since both cases lead to the same answer, we conclude that
c = 2ab.
