The selling price of the DVD player after a 15% discount is applied can be found as follows:

Discount = 15% of the marked price = (15/100)*$320 = $48

Selling price = Marked price - Discount = $320 - $48 = $272

Therefore, the actual selling price of the DVD player after a 15% discount is $272.

Answer:

$272

Step-by-step explanation:

Formula:
Selling price = Marked price - Discount

We first find the discount by taking 15% off of $320 which is $48

We then insert the Maked price and the Discount into the formula which is:

Selling price = $320 - $48
Selling price = $272

Complete question:

Find the circumference of the object which has a radius 6mm. Use 3.14 or {22}{7}.

the length of AC is 5. we can get the answer with the help of  Pythagorean theorem in triangle ABC.

what is Pythagorean theorem ?

The Pythagorean theorem is a fundamental concept in geometry that relates to the relationship between the sides of a right triangle. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides (the legs).

In the given question,

In triangle ABC, we have:

angle ABC = 90 degrees (given)

AB = 4 (given)

AD = 3 (given)

Let's call the length of AC "x". We want to find the value of x.

From the given information, we know that BD is the altitude of triangle ABC from vertex B to the side AC. Therefore, the length of BD is equal to the length of AD, which is 3.

Using the Pythagorean theorem in triangle ABD, we can find the length of the hypotenuse AB:

AB² = AD² + BD²

AB² = 3² + 4²

AB² = 9 + 16

AB² = 25

AB = 5

Now, we can use the Pythagorean theorem in triangle ABC to find the length of AC:

AC² = AB² + BC²

AC² = 5² + BC²

But we don't know the length of BC. However, we can use the fact that triangle ABD and triangle ABC are similar. This is because angle ABD is a right angle (from the definition of altitude BD), and angle ABC is a right angle (given), so angle ABD and angle ABC are both right angles. Therefore, the two triangles share angle A and are similar by the AA (angle-angle) similarity criterion.

Since triangles ABD and ABC are similar, we have:

AB/AD = AC/BD

Substituting the known values, we get:

5/3 = x/3

Solving for x, we get:

x = 5

Therefore, the length of AC is 5.

Answer: 10.95

Step-by-step explanation:

To identify the pattern, we need to look at the differences between the given numbers.

The difference between 10.21 and 9.47 is 0.74.

The difference between 10.57 and 10.21 is 0.36.

The difference between 12.15 and 10.57 is 1.58.

We can see that the differences between the numbers are not constant. However, the differences themselves follow a pattern: they are increasing by 0.38 each time.

So, to find the missing number, we can add 0.38 to 10.57:

10.57 + 0.38 = 10.95

Therefore, the missing number is 10.95.

The measure of the angle x is 41.41° in the given triangle.

Triangle is a clοsed twο-dimensiοnal shape. It is a three-sided pοlygοn. All sides are made οf straight lines. The pοint where twο straight lines jοin is the vertex. Hence, the triangle has three vertices. Each vertex fοrms an angle.

Given that cos θ = side adjacent to angle x/hypotensive

Here, side adjacent to angle x = 6

hypotensive = 8

cos x = 6/8

x = arccos 6/8

x = 41.41°

Thus, the measure of the angle x is 41.41° in the given triangle.

Part A: The diameter of the pizza from Tallahassee is 16 inches, so the radius is 8 inches. The area of the pizza is:

A = πr²

= π(8)²

= 64π inches²

Part B: The diameter of the pizza from Jaco, Costa Rica is 27.8 centimeters. Converting this to inches, we get:

27.8 cm ÷ 2.54 cm/inch = 10.94 inches

The radius is 5.47 inches, so the area of the pizza is:

A = πr²

= π(5.47)²

= 94.15π inches²

Part C: Converting the area of the pizza from Tallahassee to square centimeters, we get:

64π inches² × (2.54 cm/inch)² = 1648.89 centimeters²

The area of the pizza from Jaco, Costa Rica is 94.15π inches² × (2.54 cm/inch)² = 594.85π centimeters². Therefore, the pizza from Tallahassee is larger.

Part D: The scale factor relationship between the pizzas is:

16 inches ÷ 27.8 cm × 2.54 cm/inch = 1.462

This means that the diameter of the pizza from Tallahassee is 1.462 times larger than the diameter of the pizza from Jaco, Costa Rica. Since area is proportional to the square of the diameter (or radius), the area of the pizza from Tallahassee is (1.462)² = 2.14 times larger than the area of the pizza from Jaco, Costa Rica.

Answer:

1, the mid point

The midpoint of a line segment with endpoints (x1, y1) and (x2, y2) can be found using the midpoint formula:

midpoint = ((x1 + x2) / 2, (y1 + y2) / 2)

Substituting the given endpoints (4, -4) and (0, 9), we get:

midpoint = ((4 + 0) / 2, (-4 + 9) / 2) = (2, 2.5)

Therefore, the midpoint of the line segment with endpoints (4, -4) and (0, 9) is (2, 2.5).

2,  the slope

The slope of the line passing through the points (4, -4) and (0, 9) can be found using the formula:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

Substituting the given coordinates, we get:

slope = (9 - (-4)) / (0 - 4) = 13 / (-4) = -3.25

Therefore, the slope of the line is -3.25.

3, the length

The length of the line passing through the points (4, -4) and (0, 9) can be found using the distance formula:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Substituting the given coordinates, we get:

distance = sqrt((0 - 4)^2 + (9 - (-4))^2) = sqrt(16 + 169) = sqrt(185)

Therefore, the length of the line is sqrt(185).

4,  the equation

The equation of the line passing through the points (4, -4) and (0, 9) can be found using the point-slope form of the equation of a line:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is one of the points.

Substituting the given slope and one of the points, we get:

y - (-4) = -3.25(x - 4)

Simplifying, we get:

y + 4 = -3.25x + 13

y = -3.25x + 9

Therefore, the equation of the line passing through the points (4, -4) and (0, 9) is y = -3.25x + 9.

Using calculations based on a perpetual inventory system, the inventory balance that Altira Corporation would report in its August 31, 2024, balance sheet and the cost of goods sold it would report in the income statement, using the Average Cost Method are as follows:

The average cost method or the weighted-average cost method under the perpetual inventory system adds up all the cost of goods available for sale at each sales point and divides by the number of units available for sale in determining the average cost to be applied to the cost of goods sold.

Principally, the perpetual inventory system ensures that each inventory movement is separately recognized and the cost of goods sold determined, unlike the periodic inventory system.

August 14 for Sales of 6,000 units:

Average cost per unit = $5.46 ($54,600 ÷ 10,000)

Cost of goods sold  = $32,760 ($5.46 x 6,000)

August 25 for Sales of 7,000 units:

Average cost per unit = $5.54 ($21,840 + $33,600 ÷ 10,000)

Cost of goods sold  = $38,780 ($5.54 x 7,000)

Total cost of goods sold = $71,540 ($32,760 + $38,780)

Total cost of goods available for sale = $111,400 ($10,600 + $44,000 + $33,600 + $23,200)

The image vertices of P' if the preimage is rotated 90° counter clockwise is P'(-5,1)

An image vertex refers to a point in the plane that results from applying a transformation to a given vertex. A transformation is a mathematical operation that changes the position, size, or shape of a figure.

The image vertices of P' when the preimage polygon PSRT is rotated 90° counter clockwise can be found by applying a transformation to each vertex of the polygon. This transformation involves switching the x- and y-coordinates of each vertex and negating the new y-coordinate.

(x, y) -> (-y, x)

For the vertex P(1, 5), we can apply this transformation to get the image vertex P':

P' = (-5, 1)

Similarly, we can apply the transformation to the other vertices of the polygon:

S(1, 0) -> S'(0, 1)

R(−2, −3) -> R'(3, -2)

T(−4, 2) -> T'(2, 4)

Therefore, the image vertices of P' are P'(-5, 1), S'(0, 1), R'(3, -2), and T'(2, 4).

This means that the rotated polygon has the vertices P', S', R', and T', which form a new polygon that is 90° counter clockwise rotated from the original polygon PSRT.

Answer:

There are 26 letters in the alphabet, and 9 digits from 1 to 9.

The probability of choosing X as the letter is 1/26, since there is only one X in the alphabet.

The probability of choosing a prime number digit is 4/9, since there are 4 prime numbers among the digits 1-9 (2, 3, 5, and 7) and 9 total digits.

Therefore, the probability of choosing X followed by a prime number digit is:

P(X and prime) = P(X) × P(prime) = (1/26) × (4/9) = 4/234

So the probability of getting X followed by a prime number is 4/234, or approximately 0.017 or 1.7%.

Step-by-step explanation:

We know that, by angle sum property of triangles,

∠A +∠B+∠C=180°

⇒​ (6x−1)° ​+20°  +(x + 14)°=180°

⇒​ 6x−1 ​+20 +x + 14=180 [Open parenthesis]

⇒7x+33=180

⇒7x=180-33  [Subtracting 33  from both sides]

⇒7x=147  

⇒x=21  [Divide 7 from both sides]

Now substitute value of x in the expressions of ∠A and ∠B.

Therefore, ∠A=(6(21)-1)°=(126-1)°=125°

∠B=(21+14)°=35°

We can use the formula for the monthly payment of a loan to calculate the amount we need to pay each month:

M = (P * r * (1+r)^n) / ((1+r)^n - 1)

Where:

M = the monthly payment

P = the principal (the amount borrowed)

r = the monthly interest rate (which is the annual interest rate divided by 12)

n = the total number of months in the loan term (which is the number of years multiplied by 12)

Plugging in the given values, we get:

P = $3825

r = 15% / 12 = 0.0125

n = 4 years * 12 = 48 months

M = ($3825 * 0.0125 * (1+0.0125)^48) / ((1+0.0125)^48 - 1)

M ≈ $94.87
