The new prices are $\boxed{105\%}$ of the original prices (before the increase).Therefore, the answer is 105%.
Consider the given data,
Let the original price of an antique item be $1$.
Let us solve the problem in the following way:
Step 1:Let the original price of an antique item be $1$.
Therefore, the increased price will be $1+40\%=1.4$.
Step 2:The new price with $25\%$ off can be calculated as follows :New price = $1.4-0.25(1.4) = 1.05$.
Step 3:Therefore, the new price is $1.05$, which is $105\%$ of the original price.
Hence, the new prices are $\boxed{105\%}$ of the original prices (before the increase).Therefore, the answer is 105%.

The percentage of the original prices (before the increase) are the new prices is 105%.
The new prices after an antique store increases all of its prices by 40% and then announces a 25% off everything sale can be calculated as follows:
Suppose, the original price of the item be x.
Then the antique store increases all of its prices by 40% and the new price becomes (100+40)% of the original price i.e.1.4x
Then the store announces a 25% off on everything sale and the new price becomes (100-25)% of the new price after the price increase i.e.0.75 × 1.4x = 1.05x
Therefore, the new price after all the increase and sales is 1.05x.
So, the percentage of the original price (before the increase) is 105%.
Therefore, the percent of the original prices (before the increase) are the new prices is 105%.
This can be written as a formula below:
New price = (100 – discount %) / 100 × (1 + increase %) × original price(100 – 25) / 100 × (1 + 40) × original price
= 0.75 × 1.4 × original price
= 1.05 × original price
Thus, the percentage of the original price (before the increase) is 105%.

Let X = R and A = {0, R, {1}, R\{2}}. Then a. A is a o-algebra over R for all x ER. b. A is not a o-algebra over R. c. A is a o-algebra over R for r – 1. d. None of the above.
Let X = R and A = {0, R, {1}, R\{2}}. Then a is option (b) A is not a σ-algebra over R.
To be a σ-algebra over a set X, a collection of subsets A must satisfy three properties:
1. X must be in A.
2. If A is in A, then the complement of A (X\A) must also be in A.
3. If A₁, A₂, A₃, ... are subsets in A, then their union (A₁ ∪ A₂ ∪ A₃ ∪ ...) must also be in A.
Let's examine the given collection of subsets A = {0, R, {1}, R\{2}} over the set X = R.
1. X = R is not in A. (Property 1 is violated.)
2. The complement of {1}, which is R\{1}, is not in A. (Property 2 is violated.)
3. Taking A₁ = {1} and A₂ = R\{2}, their union A₁ ∪ A₂ = {1} ∪ (R\{2}) = {1,2} is not in A. (Property 3 is violated.)
Since A does not satisfy the three properties of a σ-algebra over R, the correct answer is (b) A is not a σ-algebra over R.

Answer:
27.0 feet
Step-by-step explanation:
Length of an arc (s) = 2πrθ/360................. Equation 1
Where r = radius of the circle, θ = angle in degree substends by the arc at the center of the circle.
From the question,
Given: r = 9 feet, θ = 3 radian = 3 (57.2950) = 171.89°
Constant: π = 3.14
Substitute these values into equation 1
s = 2(3.14)(9)(171.89)/360
s = 9715.2228/360
s = 26.99 feet
s ≈ 27.0 feet

two equal sides of a triangle are each 8 m less than six times the third side. if its perimeter is 23 m, what are its side-lengths?
The side lengths of the given triangle are 3 m, 10 m, and 10 m.
Let's assume the length of the third side of the triangle is x.
According to the given information, the two equal sides of the triangle are each 8 m less than six times the third side. Therefore, the lengths of the two equal sides can be expressed as:
6x - 8
6x - 8
The perimeter of a triangle is the sum of all three sides. In this case, the perimeter is given as 23 m:
x + (6x - 8) + (6x - 8) = 23
Simplifying the equation:
x + 6x - 8 + 6x - 8 = 23
13x - 16 = 23
13x = 23 + 16
13x = 39
x = 39 / 13
x = 3
Now that we have the value of x, we can find the lengths of the two equal sides:
Equal side 1 = 6x - 8 = 6 * 3 - 8 = 10 m
Equal side 2 = 6x - 8 = 6 * 3 - 8 = 10 m
Therefore, the side lengths of the triangle are 3 m, 10 m, and 10 m.

Answer:
25%
Step-by-step explanation:
The bottom left and top right are each a quarter of the circle and are thus 25% each. The slivers in the middle have to add up to 50% and are all evenly sized. That means that each sliver is 50/4 or 12.5%
Since there are two green slivers, we multiply 12.5% * 2 to get 25%.

True/False: let a be square real matrix if v is an eigenvector for eigenvalue λ then v is an eigenvector for eigenvalue λ
True. et a be square real matrix if v is an eigenvector for eigenvalue λ then v is an eigenvector for eigenvalue λ
In linear algebra, if a is a square real matrix and v is an eigenvector of a corresponding to eigenvalue λ, then v is also an eigenvector of a corresponding to the same eigenvalue λ. The definition of an eigenvector states that it remains unchanged (up to scaling) when multiplied by the matrix, and this property holds regardless of whether the eigenvalue is repeated or not. Therefore, if v satisfies the equation a * v = λ * v, it will still satisfy the same equation when considering the eigenvalue λ.

(q8) Which of the following is the area of the surface obtained by rotating the curve
, about the y-axis?
The area of the surface obtained by rotating the curve x = y² − 2y + 1, 0 ≤ y ≤ 2 about the y-axis isπ ∫_0^2 [(y-1)^2+1] √[1+4(y-1)^2] dy.Let's work out the solution. We need to apply the formula of surface area by revolving around the y-axis.The surface area is generated by the revolving the curve about y-axis, given as,x = y² − 2y + 1, 0 ≤ y ≤ 2.
Now, we must derive the formula to calculate the area of a surface obtained by rotating a curve around the y-axis. We use the formula given below, which involves integration of the function involved.
Let's see the formula for rotating around the y-axis:Area = 2π ∫_a^b xf(x)dxWe have given x = y² − 2y + 1, 0 ≤ y ≤ 2,To apply the above formula, we need to rearrange the given curve in terms of x,Let x = y² − 2y + 1We can obtain the value of y as, y = 1 ± √(x − 1).The limits of integration of y-axis are 0 and 2.Therefore, the area of the surface obtained by rotating the curve x = y² − 2y + 1, 0 ≤ y ≤ 2 about the y-axis isπ ∫_0^2 [(y-1)^2+1] √[1+4(y-1)^2] dy.

Find two vectors vi and v2 whose sum is (5, -5,5), where vį is parallel to (5,-1, 1) while v2 is perpendicular to (5, -1, 1). V1=__and V2 = __
The required vectors are V1 = (5/√27, -1/√27, 1/√27) and V2 = (1, 2, 3).
Given that the sum of two vectors is (5, -5, 5),
where vį is parallel to (5, -1, 1) while v2 is perpendicular to (5, -1, 1).
Now, let's find vį:
We have, vį is parallel to (5,-1, 1).
Then, a scalar k can be found such that vį = k(5,-1,1)
Using the condition that the magnitude of vį is √23,k can be found as follows:
|vį| = k|(5, -1, 1)|⟹ √(k²(5² + (-1)² + 1²)) = √23⟹ √(27k²) = √23⟹ k = 1/√27
Thus, vį = (5/√27, -1/√27, 1/√27)
Now, let's find v2:We have, v2 is perpendicular to (5,-1, 1).
Thus, the dot product of v2 and (5,-1,1) is zero.
We can write this asv2 .
(5,-1,1) = 0v2 . (5,-1,1) = 5v2₁ - v2₂ + v2₃ = 0
Thus, the vector v2 can be chosen as(1, 2, 3) as the above equation is satisfied by v2 = (1, 2, 3)
Therefore, V1 = (5/√27, -1/√27, 1/√27) and V2 = (1, 2, 3).

Give the general solution of the linear system x+y-2z = 0 2x + 2y - 3z = 1 3x + 3y +z = 7.
The general solution to the given linear system is x = 2t - 1, y = -t + 1, and z = t, where t represents any real number.
To find the general solution to the linear system, we can use the method of Gaussian elimination or matrix operations. Let's perform Gaussian elimination to solve this system.
First, let's write the augmented matrix for the system:
[1 1 -2 | 0]
[2 2 -3 | 1]
[3 3 1 | 7]
Using row operations, we can transform this matrix into row-echelon form:
[1 1 -2 | 0]
[0 0 1 | 1]
[0 0 0 | 0]
From this row-echelon form, we can deduce that the system is consistent and has infinitely many solutions.
To find the general solution, we can express the variables in terms of a parameter, let's say t. From the row-echelon form, we can see that z = t. Substituting this into the second equation, we find that 0t = 1, which is not possible. This indicates that the system is inconsistent. However, if we ignore the last equation and continue, we can express x and y in terms of t.
From the first equation, we have x + y - 2z = 0, substituting z = t, we get x + y - 2t = 0. Rearranging, we have x = 2t - 1 - y. This implies that x depends on y and t.
Similarly, from the second equation, we have 2x + 2y - 3z = 1, substituting z = t, we get 2x + 2y - 3t = 1. Rearranging, we have y = -t + 1 - x. This implies that y depends on x and t.
Therefore, the general solution to the given linear system is x = 2t - 1, y = -t + 1, and z = t, where t represents any real number.
