Answer:

The difference between the price after value added tax (VAT) and the price after discount of an article gives us the actual amount of money saved by the customer.

The price after VAT is the price of the item including the tax imposed by the government, whereas the price after discount is the price of the item after any promotional or discounted price reduction. By subtracting the price after discount from the price after VAT, we can determine the actual amount saved by the customer, which is the discount amount minus any VAT paid on the original price.

For example, if an item originally cost $100 with a 10% VAT, the price after VAT would be $110. If the item was discounted by 20%, the price after discount would be $80. The difference between the price after VAT and the price after discount would be $30, which is the actual amount saved by the customer ($20 discount minus $10 VAT paid on the original price).

Step-by-step explanation:

To calculate the actual amount saved by the customer, we need to follow these steps:

Determine the original price of the item. For example, let's say the original price of the item is $100.

Calculate the VAT amount paid on the original price. To do this, multiply the original price by the VAT rate as a decimal. For example, if the VAT rate is 10%, then the VAT amount would be:

VAT amount = original price x VAT rate

VAT amount = $100 x 0.1

VAT amount = $10

So, the VAT amount paid on the original price of $100 is $10.

Determine the discounted price of the item. For example, let's say the item is discounted by 20%, so the discounted price is:

Discounted price = original price - (original price x discount rate)

Discounted price = $100 - ($100 x 0.2)

Discounted price = $80

So, the discounted price of the item is $80.

Calculate the actual amount saved by the customer. To do this, subtract the discounted price from the price after VAT. For example:

Actual amount saved = price after VAT - discounted price

Actual amount saved = $110 - $80

Actual amount saved = $30

So, the actual amount saved by the customer is $30, which is the discount amount minus the VAT paid on the original price.

Answer:

  k = 2/5

Step-by-step explanation:

Given a diagram with triangles ONM and OAB such that M is the midpoint of OB, A lies on AN with AN = 2·OA, and P is the point of intersection of NM and AB, you want the ratio AP/AB.

Please refer to the attached diagram.

Point C is located at the midpoint of AN, which makes OA≅AC≅CN, or AN is 2/3 of ON. Segments AD and CE are parallel to AN, so divide OM into thirds. The length DM is 2 of those thirds, and the length MB is equal to OM, so is 3 of those thirds. That is, the ratio DM/DB is (2/3)/(2/3+3/3) = 2/5.

Triangle BAD is similar to triangle BPM, so the ratio AP/AB is also 2/5.

Answer:

Let x be the first unknown angle, and y be the second unknown angle.

We know that the sum of the three angles in a triangle is 180 degrees, so:

85 + 9kx + 10kx = 180

where k is a constant representing the ratio of the other two angles.

Simplifying the equation, we get:

19kx = 95

Dividing both sides by 19k, we get:

x = 5/k

Since the ratio of the other two angles is 9:10, we know that:

y = 9kx = 9k(5/k) = 45

So the measures of the two unknown angles are:

x = 5/k and y = 45

We cannot find the exact measures of x and y without more information, but we know that x and y are in a ratio of 9:10 and their sum is 180 - 85 = 95 degrees. We can set up the following equation to solve for k:

5/k + 45/k = 95

50/k = 95

k = 50/95

Using this value of k, we can find the measures of x and y:

x = 5/k = 5/(50/95) = 9.5

y = 9kx = 9(50/95)(9.5) = 47.37

Therefore, the measures of the two unknown angles are x = 9.5 degrees and y = 47.37 degrees (rounded to two decimal places).

Step-by-step explanation:

The visitor should run 1.2 miles to minimize the time it takes to reach the island.

Consider the following figure.

Let us assume that x (CD) represents the distance covered when visitor runs at a rate of 5 mph

So, the time taken by visitor would be:

t₁ = x/5

Let the distance covered 10 - x when visitor swims at a rate of 3 mph

From figure consider right triangle ABC.

Using Pythagoras theorem,

BC² = 7² + (10 - x)²

BC = [tex]\sqrt{49 + (10-x)^2}[/tex]

Now the times taken by visitor when he swims at a rate of 3 mph,

t₂ =  [tex]\frac{ \sqrt{49 + (10-x)^2}}{3}[/tex]

so, the total time would be:

t = t₁ + t₂  

[tex]t=\frac{x}{6}+\frac{ \sqrt{49 + (10-x)^2}}{3}[/tex]

Differentiating with respect to x we get,

[tex]\frac{dt}{dx}=\frac{1}{6} -\frac{(10-x)}{ \sqrt{49 + (10-x)^2}}[/tex]

consider dt/dx = 0

[tex]\frac{1}{6} -\frac{(10-x)}{ \sqrt{49 + (10-x)^2}}=0[/tex]

If we solve above equation for x we get, x = 11.2 and x = 8.8

The distance the visitor should run to minimize the time would be:

10 - 8.8 = 1.2 miles

Therefore, the required distance is 1.2 miles

Thomas can fill 35 of these 1/4 gallon containers with the light-blue mixture.

To find out how many 1/4 gallon containers Thomas can fill with the light-blue mixture, we need to divide the total volume of the mixture by the volume of one container.

The total volume of the mixture can be found by adding the volumes of blue and white paint that Thomas mixed

Total volume = 4 3/8 gallons + 6 5/8 gallons

To add these mixed numbers, we need to find a common denominator, which is 8

Total volume = (4 x 8 + 3) / 8 gallons + (6 x 8 + 5) / 8 gallons

Total volume = 35/8 gallons

Now we can set up the two equations

Total volume = number of containers x volume per container

We know the total volume is 35/8 gallons, and the volume per container is 1/4 gallon, so we can write

35/8 = (1/4) x number of containers

Number of containers = total volume / volume per container

We can rearrange the above equation to solve for the number of containers

Number of containers = total volume / volume per container

Number of containers = 35/8 / 1/4

Number of containers = 35/8 x 4

The standard deviation of demand over the lead time is 23.72.

The demand over lead time is normally distributed with a mean of 80. The reorder point for a 95% service level is 119. To calculate the standard deviation of demand over the lead time, we need to use the following formula:

z = (x - μ) / σ, where z is the number of standard deviations from the mean, x is the reorder point for a 95% service level, μ is the mean of the distribution, and σ is the standard deviation of the distribution.

To solve for σ, we need to first find the z-score for a 95% service level, which can be obtained from the standard normal distribution table.

The z-score for a 95% service level is 1.645.

Substituting the given values in the formula, we get:

1.645 = (119 - 80) / σ

Solving for σ, we get:σ = (119 - 80) / 1.645

σ = 23.72

Hence, the interest rate is 0.03 percent, or 3%. it is expressed as a percentage .

The amount of money earned or charged on a principal sum of money over time is referred to as interest in mathematics. In financial transactions like loans, investments, and savings accounts, it is frequently utilized.  Simple interest is calculated for the full time period as a fixed percentage of the principal amount. For instance, after a year, you would owe $50 in interest if you borrowed $1,000 at a simple interest rate of 5% per year.

given

We can use the following formula for simple interest to determine the interest rate given the principal, period, and simple interest:

I = P * r * t

where r is the interest rate expressed as a decimal, P is the principal, I is the simple interest, and t is the amount of time in years.

This formula can be changed to account for the interest rate:

r = I / (P * t)

In this instance, the principal, period, and simple interest are all provided. These values can be plugged in to find the interest rate:

r = I / (P * t)

We don't have enough information to determine the exact side length of either square A or square C, so we cannot directly calculate their areas. However, we can use the relationship between the areas of the squares to make some conclusions.

Since the area of square B is 64 square units, we know that its side length is √64 = 8 units.

Similarly, since the area of square C is 100 square units, we know that its side length is √100 = 10 units.

Square A is composed of square B and four identical triangles. We know the area of square B is 64 square units, so we need to determine the area of the four triangles to find the area of square A.

Each triangle has a base of 8 units (which is also the length of one side of square B) and a height of half the length of one side of square A. Let's call this length x.

The area of one triangle is (1/2) * 8 * x = 4x square units.

The total area of the four triangles is 4 times the area of one triangle, which is 16x square units.

Therefore, the area of square A is 64 + 16x square units.

We still don't know the exact value of x, but we can make some observations. Since square A is larger than square B, we know that x > 4. And since the triangles make up exactly half of square A (the other half being square B), we know that the area of square A is twice the area of the four triangles. Therefore:

64 + 16x = 2(16x)

64 + 16x = 32x

64 = 16x

x = 4

So the length of each side of square A is 8 + 2x = 16 units, and its area is 64 + 16x = 128 square units.

The length of CA is just the length of one side of square C, which is 10 units.

For your party, you need to invite at least 23 randomly chosen guests in order to have a probability of 2/3 or higher of having a guest with the same birthday as yours. This is known as the birthday paradox and it is based on the probability of two people having the same birthday. To calculate the number of guests needed for the probability of having at least one match, you can use the following formula:

P(at least one match) = 1 - (365/365)^n

where n is the number of guests you invite.
So, to solve for n, you would rearrange the equation to:

The equation of the ellipse is:

(x^2)/16 + (y^2)/4 = 1

Step-by-step explanation:

An ellipse is a set of points on a plane, the sum of whose distances from two fixed points (called foci) is constant. The distance between the foci of an ellipse is denoted by 2c, and the distance between the center of the ellipse and one of its vertices is denoted by a.

In this problem, the foci are located at (2,0) and (-2,0), so the distance between the foci is 2c = 4, which means that c = 2. The major vertices of the ellipse are located at (4,0) and (-4,0), so the distance between the center and one of the vertices is a = 4.

The formula for the equation of an ellipse centered at the origin is:

(x^2)/(a^2) + (y^2)/(b^2) = 1

where a is the distance from the center to a vertex, and b is the distance from the center to a co-vertex. Since the center of this ellipse is at the origin and the major axis lies on the x-axis, we know that b = a, so we can substitute a for b in the equation:

(x^2)/(a^2) + (y^2)/(a^2) = 1

To find a, we use the fact that c^2 = a^2 - b^2:

a^2 - b^2 = c^2

a^2 - a^2 = 4

b^2 = 4

b = 2

Now we can substitute a = 4 and b = 2 into the equation:

(x^2)/(16) + (y^2)/(4) = 1

This is the equation of the ellipse.

Step-by-step explanation:

We know that Q and P are supplementary because they are parallelograms.

So,

180 - < Q = < P                               Use substitution

180 - 76 = < P                                 Solve

180 - 76 = 104

104 = < P

Since we know that < QPK and < KPS are congruent and are apart of < P we can multiply < P by 1/2 to find either < QPK or < KPS.

So,

1/2(104)                                           Simplify using distributive property

If a shape is a triangle, then it’s interior angles all add up to 180.

< KPS + < PKS + < KSP = 180        Use substitutions

52 + 90 + < KSP = 180                  Move variables to one side

< KSP = 180 - 52 - 90                    Simplify

Step-by-step explanation:

You can add Y together because they have the same variable making it 10y

The equation is now 10y - 84 = 180

Add 84 to 180 since on the left side it was -84 (Imagine it crossed a magic bridge and become the opposite of what it is)

The equation is now 10y = 264

Divide the equation by 10 because 10 crossed a "magic bridge" to the other side and became division instead of multiplication

The equation is now solved = 26.4

We can cross check this by adding it to the first equation

3(26.4) + 7(26.4) - 84

which gives us 180

Hope this helps

Answer: y=26.4

Step-by-step explanation:

First we need to simplify 3y+7y .... that would be 10y.

Now we have 10y-84=180. We can add 84 to both sides of the equation

So now we have 10y= 180+84 = 10y= 264

Divide both sides by 10= y= 26.4

Now we can check this answer by inputting 26.4 to all the y values in the equation.

(3*26.4) +(7*26.4) - 84=180

79.2 + 184.8 -84=180

180=180    so we know 26.4 is the correct answer

Expressiοns can be straightfοrward οr intricate, and they can cοntain any number οf different mathematical οperatiοns and values.

Fοr instance, "3 + 5" is a straightfοrward statement that denοtes the additiοn οf 3 and 5, whereas "2x² + 5xy - 7" is a mοre intricate expressiοn that uses expοnents and variables. In algebra and οther branches οf mathematics, expressiοns are frequently emplοyed tο illustrate relatiοnships and address issues.

Let's first simplify each phrase that appears after the square rοοt:

√32x^3 = √(16x²) * √(2x) = 4x√2x √16x³ = √(16x²) * √x = 4x√x 4√x³ = 4√(x²) * √x = 4x√x √2x³ = √(2x²) * √x = √2x * x√x

Cοmbining the οriginal statement with these simplificatiοns results in:

32x³ - 16x³ + 4x³ - 2x³ = 4x²x - 4xx + 4xx - xx = 4x²x - xx = 2x (4x - x²).

As 4x and x2 are bοth nοn-negative because x 0, their difference is alsο

non-negative.

Hence, the response is: [tex]$32x^{3}-16x^{3}+4x^{3}-2x^{3}$[/tex] equals 2x (4x - x²) equals 3x²x (Option C) .

Answer:

= 75 cubic units

Step-by-step explanation:

Volume = height * width * length

Then:

volume = 4 1/2 * 3 1/3 * 5

4 1/2 = 4 + 1/2 = 8/2 + 1/2 = 9/2

3 1/3 = 3 + 1/3 = 9/3 + 1/3 = 10/3

Then:

volume = 9/2 * 10/3 * 5/1

volume = (9*10*5) / (2*3*1)

volume = 450 / 6

Volume = 75 cubic units
