The width of the rectangular rug is 13 feet and the length of the rectangular rug is 26 feet.

Area of a rectangle formula: A = L * W. A

rectangle's length and width are multiplied to produce its area.

A is the area, L is the length, and W is the width or girth, where

A = L * W.

The corresponding sides of the rectangular rug and the rectangular floor must be proportional if they are alike.

Let's use "x" to represent the rug's width. The floor measures 32 feet in length and 26 feet in width, and the length of the rug is 16 feet according to the details provided. Since the rug and the surface are comparable, we can establish the following ratio:

Rug width/floor width = rug length/floor length

x / 26 = rug's length / 32

We can cross-multiply and then solve for "x" to find the answer:

32x = 26 * Rug's length

x =  (26 * Rug Length) / 32

[tex]= \frac{26 * 16}{32} \\= \frac{26}{2} \\= 13[/tex]

Therefore x ( the width of the rug) is = 13 feet.

Imaginary Numbers are 21. (5+2i)/ 4i is  -(5/4) + (1/2)i, 22. 3i/(-2+i) is -1.5i + 0.75. 23. (3-2i)/(4-3i) is 4/5 + (1/25)i, 24. 7/(5-2i) is (14/29) + (7/29)i.

In mathematics, imaginary numbers are a type of complex number that can be written in the form a + bi, where a and b are real numbers and i is the imaginary unit, which is defined as the square root of -1.

Imaginary numbers were first introduced in the 16th century as a solution to certain polynomial equations that did not have real solutions. They were initially met with skepticism and derision, but eventually became widely accepted as a fundamental part of complex analysis and number theory.

One of the key properties of imaginary numbers is that when they are multiplied by themselves, the result is always a negative real number. For example, i * i = -1. This property is what makes imaginary numbers useful for representing certain physical quantities, such as the amplitude and phase of an oscillating system.

21. (5+2i)/ 4i = -(5/4) + (1/2)i

To divide complex numbers, we can multiply the numerator and denominator by the conjugate of the denominator. Here, the conjugate of 4i is -4i.

(5+2i)/ 4i = (5+2i)/4i * (-4i/-4i)

= -(20i - 8)/(-16)

= -(20i - 8)/16

= -(5/4) + (1/2)i

Therefore, (5+2i)/ 4i = -(5/4) + (1/2)i.

22. 3i/(-2+i) = -1.5i + 0.75

We can again use the conjugate to simplify the division of complex numbers.

3i/(-2+i) = 3i/(-2+i) * (-2-i)/(-2-i)

= (-6i -3)/(-5)

= 3/5 + 1.5i

Therefore, 3i/(-2+i) = -1.5i + 0.75.

23. (3- 2i)/(4-3i) = (18+5i)/25

Using the conjugate:

(3-2i)/(4-3i) = (3-2i)/(4-3i) * (4+3i)/(4+3i)

= (12+9i-8i-6i²)/(16+12i+12i-9i²)

= (20+i)/25

= 20/25 + (1/25)i

= 4/5 + (1/25)i

Therefore, (3-2i)/(4-3i) = (18+5i)/25 = 4/5 + (1/25)i.

24. 7/(5-2i) = (14/29) + (7/29)i

Using the conjugate:

7/(5-2i) = 7/(5-2i) * (5+2i)/(5+2i)

= (35+14i)/(29)

= (14/29) + (7/29)i

Therefore, 7/(5-2i) = (14/29) + (7/29)i.

The length of side AC of right triangle ABC is 13. So,the option A is correct

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted Δ triangle ABC.

We can use the trigonometric ratios of right triangle ABC to find the value of y. 

 We label the sides of the triangle as follows: 

 Side AB (opposite angle C) is the hypotenuse. 

 The length of side BC (opposite angle A) is 13. 

 Side AC (opposite angle B) is the unknown side called y. 

 Since angl

e A is 45 degrees, we know that the sine and cosine of angle A are equal: 

 sin(A) = cos(A) = 1/√2 

 Using the Pythagorean theorem, we can relate the lengths of the sides of a triangle: 

 AB² = AC² BC² 

 Substituting the known values, we get: 

 AB² = y² 169 

 Taking the square root of both sides gives us: 

 AB = √(y² 169) 

 Now we can use the sine ratio to relate the length of the sides: 

 sin(A) = opposite/hypotenuse 

 Substituting the known values, we get: 

 1/√2 = and/√(y² 169) 

 By cross linking and simplifying, we get: 

 y√2 = √(y² 169) 

 Squaring both sides we get: 

 2y² = y² 169 

 Subtracting y² from both sides, we get: 

 y² = 169/1 

 Taking the square root of both sides gives us: 

 y = ±13 

 Since y represents length, we can reject the negative solution and the value of y is: 

 y = 13 

 Therefore, the length of side AC of right triangle ABC is 13.

Answer: Approximately $4,176.19 today for an investment that returns $800 each year for 6 years

Step-by-step explanation:

To calculate the present value of an investment that returns $800 each year for 6 years at a discount rate of 4 percent, we can use the formula for the present value of an annuity:

PV = C x [(1 - (1 / (1 + r)^n)) / r]

where PV is the present value, C is the annual cash flow, r is the discount rate, and n is the number of years.

Plugging in the given values, we get:

PV = 800 x [(1 - (1 / (1 + 0.04)^6)) / 0.04]

PV = $4,176.19 (rounded to the nearest cent)

Therefore, if the discount rate is 4 percent, you would be willing to pay approximately $4,176.19 today for an investment that returns $800 each year for 6 years

Dοnοvan's hοurly wage than his brοther's hοurly wag wοuld be, $7.98/hοur

Average salary is the average amοunt οf mοney earned by wοrkers in a particular industry, ecοnοmy, area, etc.

Tοtal hοurs wοrked by Dοnοvan = 40 hοurs/week x 48 weeks/year = 1,920 hοurs/year

Next, we can calculate Dοnοvan's hοurly wage:

Hοurly wage οf Dοnοvan = Annual salary οf Dοnοvan / Tοtal hοurs wοrked by Dοnοvan

= $55,000 / 1,920 hοurs/year

= $28.65/hοur

Similarly, we can find the tοtal number οf hοurs that his brοther wοrks in a year:

Tοtal hοurs wοrked by Dοnοvan's brοther = 40 hοurs/week x 52 weeks/year = 2,080 hοurs/year

Hοurly wage οf Dοnοvan's brοther = Annual salary οf Dοnοvan's brοther / Tοtal hοurs wοrked by Dοnοvan's brοther

= $43,000 / 2,080 hοurs/year

= $20.67/hοur

Difference in hοurly wages = Hοurly wage οf Dοnοvan - Hοurly wage οf Dοnοvan's brοther

To solve this problem, we can use the trigonometric functions sine, cosine, and tangent.

First, let's draw a diagram:

             A (top of the mountain)

            /|

           / |

         /    |  h (height of mountain)

       /      |

     / θ     |

B /_____|

   d (distance from base)

We are given that the distance from the base of the mountain to point B is 1/2 mile, or 2640 feet (since there are 5280 feet in a mile). We are also given that the angle of elevation from point B to point A is 65 degrees, and that the angle between the ski lift and the ground is 15 degrees.

Let's start by finding the height of the mountain h. We can use the tangent function, since we know the opposite (h) and the adjacent (d) sides of the right triangle formed by points A, B, and the foot of the mountain (call it point C):

tan(65) = h / d

h = d * tan(65)

Plugging in the values, we get:

h = 2640 * tan(65)

h ≈ 7855 feet

Next, let's find the length of the ski lift. We can use the cosine function, since we know the adjacent (d) and hypotenuse (L) sides of the right triangle formed by points B, the foot of the mountain, and the base of the ski lift (call it point D):

cos(15) = d / L

L = d / cos(15)

Plugging in the values, we get:

L = 2640 / cos(15)

L ≈ 2736 feet

Therefore, the length of the ski lift from the beginning to the end is approximately 2736 feet.

We can start by finding the sum of the given numbers and equating it to the product of 20 and 8 (the number of elements):

6 + 29 + 3 + 14 + q + (q+8) + Q^2 + (q-10) = 20 * 8

Simplifying the left side by combining like terms, we get:

2q^2 + 20q - 100 = 124

Bringing everything to one side, we get:

2q^2 + 20q - 224 = 0

Dividing both sides by 2, we get:

q^2 + 10q - 112 = 0

Now, we can use the quadratic formula to solve for q:

q = (-10 ± √(10^2 - 4(1)(-112))) / (2(1))

q = (-10 ± 18) / 2

So the possible values of q are:

q = 4 or q = -14

To verify, we can substitute these values back into the original equation and see if the mean is indeed 20:

For q = 4:

(6 + 29 + 3 + 14 + 4 + 12 + 16 + -6) / 8 = 20 (checks out)

For q = -14:

(6 + 29 + 3 + 14 - 14 - 6 + 196 + -24) / 8 = 20 (checks out)

Therefore, the possible values of q are 4 and -14.

Answer:

60°

120°

Step-by-step explanation:

Supplementary angle are those that sum up to a total of 180 degrees.

So, let's have 2 angles, angle A and angle B.

Angle A's measure is α so the measure of angle B is 2α.

The sum of these two angles sum up to 180 degrees, so we can say that:

α + 2α = 180°

3α = 180°

α = 60°

So, one of our angles is 60° and the other is (2*60)° which is 120°.

Find the current sale price. Round to the nearest cent if necessary.

• Members of the store's loyalty club get an additional 10% off their computer purchases. How much do club members pay for the computer with their discount?

To find the current sale price, we first need to calculate the markdown amount. We know that the markdown is 30% of the original selling price, which is $776, so the markdown amount is:

30% of $776 = 0.30 x $776 = $232.80

The sale price is then the original selling price minus the markdown amount:

Sale price = $776 - $232.80 = $543.20

Therefore, the current sale price of the computer system is $543.20.

Next, we need to calculate the price that club members pay after their discount. We know that club members get an additional 10% off the sale price, which is $543.20, so their discount amount is:

10% of $543.20 = 0.10 x $543.20 = $54.32

The price that club members pay is then the sale price minus their discount amount:

Price for club members = $543.20 - $54.32 = $488.88

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

where:

P = monthly payment

r = monthly interest rate

A = loan amount

n = total number of payments

In this case, we have:

A = $128,000.00

n = 25 years * 12 months/year = 300 months

r = 5.3% / 12 = 0.00441666667

Using the formula, we can calculate the monthly payment:

P = (0.00441666667 * $128,000.00) / (1 - (1 + 0.00441666667)^(-300))

P = $770.82

Now, we can create the amortization table:
