To estimate the number of square feet of carpeting needed for a room with dimensions x, y, w, z, and n, we can use the formula A = xy + w[z(2n - 1) + 2n].

What are the dimensions?

The given formula for estimating the number of square feet, A, of carpeting needed for a room x feet by y feet containing a stairway w feet by z feet with n stairs is:

A = xy + w[z(2n - 1) + 2n]

Let's break down this formula to understand the different parts:

The term w[z(2n - 1) + 2n] represents the additional area needed to cover the stairway. We add this to the area of the main part of the room, xy, to get the total area of carpeting needed, A.

So to estimate the number of square feet of carpeting needed for a room with dimensions x, y, w, z, and n, we can use the formula A = xy + w[z(2n - 1) + 2n].

Answer:

slope = 15

Step-by-step explanation:

calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, 6) and (x₂, y₂ ) = (2, 21) ← 2 ordered pairs from the table

m = [tex]\frac{21-6}{2-1}[/tex] = [tex]\frac{15}{1}[/tex] = 15

the linear relationship is then of the form

y = mx + c ( m is the slope and c the y- intercept )

from the table the point (0, - 9 ) crosses the y- axis at - 9 ⇒ c = - 9

y = 15x - 9 ← linear relationship

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

The measure of angle D is 100°

A triangle is a polygon with three sides having three vertices. The angle formed inside the triangle is equal to 180 degrees. It means that the sum of the interior angles of a triangle is equal to 180°.

Since the the sum of angle in a triangle is 180°, then to get the value of angle D will subtract the sum of the known angles from 180.

Therefore,

angle D = 180-( 40+40)

= 180-80

= 100°

therefore the measure of angle D Is 180°

The loan's simple interest rate is 5.232% per quarter.

What is the formula for the future value of a loan with simple interest?

A = P(1 + rt)

where A is the future value, P is the principal, r is the simple interest rate per period, and t is the number of periods.

In this case, we have:

The sides of the right triangle are 15 cm, 20 cm, and 25 cm.

What is triangle?

A triangle is a three-sided polygon with three vertices. The triangle's internal angle, which is 180 degrees, is constructed.

Let x be the length of the shorter leg of the right triangle.

Then, according to the problem statement, the longer leg is 5 cm more than the shorter leg, which means its length is x + 5 cm.

The hypotenuse is 10 cm more than the shorter leg, so its length is x + 10 cm.

By the Pythagorean theorem, we have:

x² + (x+5)² = (x+10)²

Expanding the squares and simplifying, we get:

x² + x² + 10x + 25 = x² + 20x + 100

Subtracting x² and simplifying further, we get:

x² - 10x - 75 = 0

Factorizing the left-hand side, we get:

(x - 15)(x + 5) = 0

Therefore, the possible solutions are x = 15 and x = -5, but x cannot be negative in this context, so we take x = 15 cm.

Then, the longer leg is x + 5 = 20 cm, and the hypotenuse is x + 10 = 25 cm.

Therefore, the sides of the right triangle are 15 cm, 20 cm, and 25 cm.

Answer:

∠A=125° and ∠B=35°

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°

Answer:

d= 90 Degrees

e= 97 Degrees

f = 83

Answer:

Step-by-step explanation:

To find:-

Answer:-

We can see that angles e and 97° are vertically opposite angles. So they will be equal as vertically opposite angles are equal .

Hence here ,

→ e = 97°

Secondly e and f form linear pair , and the sum of linear pair is 180° . Hence here ,

→ e + f = 180°

→ 97° + f = 180°

→ f = (180-97)°

→ f = 83°

Same goes with d and 90° . They both form linear pair. So that ,

→ 90° + d = 180°

→ d = 180°-90°

→ d = 90°

These are the required values of the unknown angles.

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)

A)  64π inches² B) 94.15π inches² C) the pizza from Tallahassee is larger. D)  The scale factor relationship between the pizzas is:  1.462

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:

7x = 126 is the equation

She sold 18 t-shirts.

Step-by-step explanation:

Since she sold t-shirts for 7 each, we need to find how many T-shirts she sold. 126 dollars is how much she made, so we need to divide.

126/7 = 18.

The equation would be:

7x = 126.

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%.

the axis of symmetry for the function f(x) = 7 - 4x + x²2 is x = 2.

Why it is and what does symmetry mean?

To find the axis of symmetry of the quadratic function f(x) = 7 - 4x + x²2, we can use the formula:

x = -b / 2a

where a and b are the coefficients of the x²2 and x terms, respectively, in the quadratic equation ax²2 + bx + c = 0.

In the given function, a = 1 and b = -4. Substituting these values into the formula, we get:

x = -(-4) / 2(1) = 2

Therefore, the axis of symmetry for the function f(x) = 7 - 4x + x²2 is x = 2.

Symmetry is a property that describes a balanced and consistent arrangement of parts or elements that are similar in size, shape, and position. In mathematics, symmetry refers to the idea that a geometric object, function, or equation remains unchanged after some transformation, such as a reflection, rotation, or translation.
