My answer might be a bit off since I'm not really sure what you mean by "Rs 80", which I interpreted as $80, but if my interpretation is wrong, you can still use all the same steps and you should get the correct answer
Step-by-step explanation:
So we can represent the price of each tumbler as the variable "P", since it's some unknown value we're solving for. Let's also just say that "T" is the total price that she paid for all of the tumblers.
Using this equation we can derive the following equation.
1000P = T
Since multiplying the price of each glass tumbler times the price of one glass tumbler should equal the entire price.
Now she only sold 900 of them, since 100 were broken, and she sold them each for 80. So knowing this we can find how much she made in total from selling the remaining 900 glass tumblers
900 * 80 = 72,000
Now if she made a loss of 4%, that means the total money she made back, is only 96% the amount of money she paid for the product. The reason for this is (100-4)% represents a 4% loss.
Remember, how T represents the entire price, well we know that 72,000 represents 96% of it's value. To find what x% is of some number, you generally convert the percentage into a decimal by dividing by 100, so to find x% of some variable "a" you generally use the following equation: [tex]a*\frac{x}{100}[/tex] where the value of this expression will be equal to x% of a.
So let's convert 96% to decimal form: [tex]\frac{96}{100} = 0.96[/tex]. Now if we multiply this decimal 0.96 by T, we should get 72,000 since the 72,000 represents 96% of the original value
[tex]0.96T = 72,000[/tex]
To find the original value of T, we simply divide both sides by 0.96
[tex]T = 75,000[/tex]
So now that we know the original total price, we can use the original equation we derived to solve for P, which represents the price of each individual tumbler.
Original Equation
[tex]1000P = T[/tex]
Substitute 75,000 as T
[tex]1000P = 75,000[/tex]
Divide both sides by 1,000
[tex]75=P[/tex]
This means she sold each for 75

Connect the center with one end of the chord, this gives us a right triangle with hypotenuse of x, one leg of 6 and another leg of 24/2 = 12.
Use Pythagorean to find the value of x:
x² = 6² + 12²x² = 36 + 144x² = 180x = √180x = 13.4 (rounded)Correct choice is C.
Answer:
x = 13.4
Step-by-step explanation:
Definitions
Radius: a straight line from the center of the circle to its circumference.
Chord: a straight line joining two points on the circle.
Perpendicular: at a right angle (90°).
Isosceles triangle: a triangle with 2 sides of equal length and 2 congruent base angles.
From inspection of the given diagram:
radius = xchord = 24 unitssegment of the radius perpendicular to the chord = 6 unitsIf lines are drawn from the center of the circle to the endpoints of the chord, an isosceles triangle is created with base of 24 units and height of 6 units.
The isosceles triangle is made up of two right triangles with base of 12 units and height of 6 units. The radii are the hypotenuse of these right triangles. Therefore, to calculate the radius of the circle (x), use Pythagoras Theorem.
Pythagoras Theorem
[tex]\sf a^2+b^2=c^2[/tex]
where:
a and b are the legs of the right trianglec is the hypotenuse (longest side) of the right triangleTherefore:
[tex]\sf \implies 6^2+12^2=x^2[/tex]
[tex]\implies \sf x^2=36+144[/tex]
[tex]\implies \sf x^2=180[/tex]

A standard deck of cards contains 52 cards. There are four suits (spades, clubs, hearts, and diamonds) and thirteen of each suit (2-10, jack, queen, king, ace). One card is selected at random from the deck. What is the probability the card selected is an Ace or a heart?
The probability of selecting an ace or a heart when one card is drawn from 52 cards is 1/52.
Given that there are 52 cards in which there are 13 cards each for spades,clubs,hearts and diamonds.
We are required to find the probability of getting an ace or a heart when one card is drawn from 52 cards.
Probability is basically the chance of happening an event among all the events possible. It lies between 0 and 1. It cannot be negative. The probability can be calculated through following formula:
Probability=Number of items/total number of items.
Number of hearts=13
Number of ace=4
Probability of getting an ace or a heart when one card is drawn=P(X=heart)*P(X=ace)
=13/52 * 4/52
=52/(52*52)
=1/52
Hence the probability of getting an ace or heart when one card is drawn from standard deck of cards is 1/52.

therefore the measure of AC = AB and they are both = [tex]9\sqrt{2}[/tex]
for this special triangle the measure of hypotenuse (CB in here) is represented with [tex]x\sqrt{2}[/tex] and the legs are represented with x, each

If the graph of a budget function has an x-intercept at 2 and the y-intercept at 5, name two ordered pairs that would fall on this line.
(2, 0) (0, 5)
(0, 2) (5, 0)
(2, 0) (2, 5)
(0, 2) (2, 5)
Based on the graph of the budget function with the x-intercept and the y-intercept, the two ordered pairs that would fall on this line are (2, 0) (0, 5).
What points fall on this line?The x-intercept is the point on the graph where the budget function would cross the x-intercept.
At this point, the value of y would be 0 because the x-axis intersects the y-axis at y = 0.
An x-intercept of 2 would therefore have the point, (2,0).
The y-intercept would be the point where the y axis is crossed. At this point, x will be zero because the y-axis intercepts the x-axis at the value, x = 0.
A y-intercept of 5 would therefore yield a point of (0, 5).

Use lagrange multipliers to find the minimum distance between the origin and the plane 3x y 2z = 28
The minimum distance between the origin and the plane 3x + y + 2z = 28, using the Lagrange Multipliers is 8.73 units.
In the question, we are asked to use Lagrange multipliers to find the minimum distance between the origin and the plans 3x + y + 2z = 28.
Lagrange multipliers state that if we want to minimize a function, f(x, y, z), subject to a constraint g(x, y, z) = constant, then ∇f = λ∇g.
We want to minimize the distance, and the distance formula says that the distance from the origin to a point (x, y, z), is given as:
D = √(x² + y² + z²), which can also be shown as:
D² = x² + y² + z².
The gradient of this function is: (2x + 2y + 2z), which needs to be equal to the gradient of the constraint equation multiplied by the constant, λ, that is, λ(3, 1, 2), which gives:
2x = 3λ, or, x = (3/2)λ,
2y = λ, or, y = λ/2, and,
2z = 2λ, or, z = λ.
Substituting these in the equation of the plane, 3x + y + 2z = 28, we get:
3(3/2)λ + λ/2 + λ = 28,
or, 6λ = 28,
or, λ = 28/6 = 14/3.
Thus, we get:
x = (3/2)λ = 7,
y = λ/2 = 7/3, and,
z = λ = 14/3.
Substituting these in the distance formula, we get:
D = √(7² + (7/3)² + (14/3)²) = √(49 + 49/9 + 196/9) = √(686/9) = 8.73.
Thus, the minimum distance between the origin and the plane 3x + y + 2z = 28, using the Lagrange Multipliers is 8.73 units.

A) (0, 0)
B) (-4, 0)
C) The lines don't intersect
D) The lines intersect at an infinite number of points
The correct option regarding the point at which the linear functions intersect is given by:
C) The lines don't intersect.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For line m, we have that the y-intercept is of b = 8. When x changes by 4, y changes by 8, hence the slope is of 2, and the equation is:
y = 2x + 8.
Line n, in slope-intercept format, is given by:
-8x + 4y = 24
4y = 8x + 24
y = 2x + 6
Hence:
2x + 8 = 2x + 6
0x = -2
Which is impossible, hence they do not intersect and option C is correct.
