Using percentages, we know that $515.87 approx is the purchase price at the start.

In mathematics, a percentage is a number or ratio that is expressed as a fraction of 100.

Although "pct," "pct," and occasionally "pc" are also employed as acronyms, the percent symbol "%" has been most usually used to denote it.

A% is a number that has neither dimensions nor a specified unit of measurement.

For example, if you properly completed 75 out of 100 questions on a test, you would have received a 75% grade (75/100).

So, in mathematics, a percentage is a number or ratio that is expressed as a fraction of 100. Let x represent the initial asking price ( in dollars ),

After 10% is deducted, 10% of x less the new selling price, or x - 0.1x, equals 0.9x.

Having reduced the price by 30%,

The final selling price equals 90% less than 90%.

= 0.9x - 0.3 × 0.9x

= 0.9x - 0.27x

= 0.63x

The answer to the query is:

0.63x = 325

x = 325/0.63

x = 515.87

Therefore, using percentages, we know that $515.87 approx is the purchase price at the start.

Answer:

x = 72

Step-by-step explanation:

We first remove the parenthesis

2x-90+2x-90+x = 180

Group like terms

2x+2x+x-90-90 = 180

Add the like terms with each other

5x-180 = 180

Add 180 to both sides to cancel the -180 on the left side of the equation

5x = 180+180 = 360

We then divide 360 by 5 to get 72 as x

Answer:

The ratio of Pablo's age to Richard's age to Tristan's age is 6:7:4.

Step-by-step explanation:

The ratio of Pablo's age to Richard's age is 6: 7 and the ratio of Pablo's age to Tristan's age is 5: 4. To find the ratio of Pablo's age to Richard's age to Tristan's age, we can first find the ratio of Richard's age to Tristan's age by multiplying the ratios of Pablo's age to Richard's age and Pablo's age to Tristan's age. The product of these ratios is 6/7 * 5/4 = 30/28. Since the ratio of Pablo's age to Richard's age is 6:7, we can add this ratio to the ratio of Richard's age to Tristan's age to find the ratio of Pablo's age to Richard's age to Tristan's age. Thus, the ratio of Pablo's age to Richard's age to Tristan's age is 6:7:4.

The Production Possibility Frontier (PPF) is a curve on a graph that represents the possible amount that can be produced by two products if they rely on the same finite resource for manufacturing. PPF is also known as the production possibility curve.

Given:

05 machines make 05 plates in 05 hours.

rate of 3 machines is 1 plate per minute,

The answer is that the ball was in the air for 0.56 seconds when it was 54 feet above the ground. This was determined by using the Quadratic Formula to solve the equation 54 = -16s^2 + 96s for the variable s.

Step-by-step explanation:

To solve this equation, we can use the Quadratic Formula, which states that for a quadratic equation in the form ax^2 + bx + c = 0, the solutions are given by:

x = (-b +/- sqrt(b^2 - 4ac)) / (2a)

In this case, a = -16, b = 96, and c = -54. Plugging these values into the Quadratic Formula, we get:

s = (-96 +/- sqrt(96^2 - 4 * -16 * -54)) / (2 * -16)

= (96 +/- sqrt(9216 + 4352)) / -32

= (96 +/- sqrt(13,568)) / -32

Since we want the time (in seconds) that the ball was in the air, we need to find the positive solution to this equation. Thus, we have:

s = (96 + sqrt(13,568)) / -32

= (96 + 120) / -32

= 0.5625 seconds

Rounding this value to the nearest hundredth of a second, we get 0.56 seconds. This means that the ball was in the air for 0.56 seconds when it was 54 feet above the ground.

To solve this equation, we used the Quadratic Formula. This method allowed us to find the time (in seconds) that the ball was in the air by solving for the value of the variable s in the given equation. This helped Vue answer his question by providing a numerical value for the amount of time that the ball was in the air when it was 54 feet above the ground.

The inequality y < -1/2x² - 6x - 16 corresponds to the right representation.

Along with passing through (-8, 0), (-6, 2), and (-4, 0), it also has a vertex there.

We need to find its equation.

We must take into account the provided details on the parabola's properties and its points in order to choose the proper inequality to symbolize the shaded area of the parabola.

The vertex of the parabola is at (-6, 2), and it opens downward. This indicates that the equation for the parabola is of the type y = a(x - h)² + k, where (h, k) denotes the vertex.

In this case, h = -6 and k = 2.

Plugging in the values of the vertex into the equation, we have:

y = a(x - (-6))² + 2

y = a(x + 6)² + 2

Now we can use one of the points that the parabola passes through to solve for the value of 'a'.

The point (-8, 0) lies on the parabola. Substituting these values into the equation:

0 = a(-8 + 6)² + 2

0 = a(-2)² + 2

0 = 4a + 2

4a = -2

a = -1/2

Substituting the value of 'a' into the equation:

y = (-1/2)(x + 6)² + 2

Expanding and rearranging the equation:

y = (-1/2)(x² + 12x + 36) + 2

y = (-1/2)x² - 6x - 18 + 2

y = (-1/2)x² - 6x - 16

Therefore, the correct inequality that represents the shaded region is:

y < -1/2x² - 6x - 16

The number of hours it will take 3 employees to tag all garments is 1.60 hour

From the question, we have the following parameters that can be used in our computation:

Number of garments = 575

Time taken by an employee on a garment = 30 seconds

This means that the variation is an inverse variation

If the time taken by an employee on a garment is 30 seconds

Then the time taken by 3 employees on a garment is

Time taken = 30 seconds/3

Evaluate

Time taken = 10 seconds

For 575 garments, we have

Time taken = 10 seconds * 575

Evaluate

Time taken = 5750 seconds

Express in hours

Time taken = 1.60 hour

Hence, the time taken is 1.60 hour

The probability that a random sample of 60 households will have exactly 20 households with 3 or more vehicles is 0.90931

What is mean and standard deviation?

Using Normal Approximation to Binomial

Mean = n * P = ( 60 * 0.3 ) = 18

Variance  = n * P * Q  = ( 60 * 0.3 * 0.7 ) = 12.6

Standard deviation  = √(variance) = √(12.6)  = 3.5496

P ( X = 20 )

Using continuity correction

P( n - 0.5 < X < n + 0.5 )

= P ( 20 - 0.5 < X < 20 + 0.5 )

= P ( 19.5 < X < 20.5 )

Using EXCEL,

P ( 19.5 < X < 20.5 )

= P(X < 20.5) - P(X < 19.5)

= BINOM.DIST ( 20.5 , 60 , 0.30, TRUE) - BINOM.DIST ( 19.5 , 60 , 0.30, TRUE)

= 0.7622 -  0.66916

Three dozen of these apples cost if Annalisa bought is equivalent to $23.40.

Given that:

Annalisa bought two dozen apples for $15.60.

Therefore, the value of one dozen apples will be calculated by dividing both values by 2.

i.e. We can say that,

Annalisa bought one dozen apples for $15.60/2 = $7.80.

So, we have to find out the value of three dozen of these apples.

Hence, we multiply both the 3 to get the cost of three dozen of apples.

Multiplying we get,

Annalisa if bought three dozen apple costs = $7.80 x 3 = $23.40.

We also know that, one dozen = 12 apples

So, three dozen = 36 apples

Therefore, we can say the cost of one apple = 23.40/36 = $0.65

Hence, it costs $23.40 for three dozen apples to Annalisa.
