A desk is purchased for $277. Calculate it's worth after depreciating for 5 years if it's depreciation rate is 20% per year

Answers

Answer: $90.77

Step-by-step explanation:

Just did the test

The desk cost $90.76 after Depreciation rate.

What is Depreciation rate?

The depreciation rate is the proportion at which an asset depreciates during its anticipated useful life. It may also be described as the portion of an organization's long-term investment in an asset that the organisation claims as a tax-deductible expense over the course of the asset's useful life.

Given:

A desk is purchased for $277.

In one year the  depreciation rate is 20% per year.

So, In one year depreciation amount

= 20% of 277

= $55.4

After 2nd year

= 221.6 - 20% of 221.6

= $177.28

After 3rd year

= 177.28- 20% of 117.28

= $141.824

After 4th year

= $113.4592

After 5th year

= 113.4592 - 20% of 113.4592

= $90.76

A: This is INCORRECT because fabric B is medium duty

B: This is INCORRECT because Fabric B lasted longer than Fabric A

C: This is CORRECT because Fabric B is medium duty fabric

D:This is CORRECT because Fabric B lasted more rubs than Fabric A because its a more durable fabric

Answers

Answer:

n = √3

m = √3

Step-by-step explanation:

The triangle is an isosceles right triangle with 2 equal base angles of 45° each.

Thus:

Reference angle = 45°

Hypotenuse = √6

Opposite = m

Adjacent = n

✔️To find m, apply the trigonometric function SOH, we have:

Sin 45 = opp/hyp

Sin 45 = m/√6

√6 × 1/√2 = m (sin 45 = 1/√2)

√6/√2 = m

√(6/2) = m

√3 = m

m = √3

✔️To find n, apply the trigonometric function, CAH:

Cos 45 = adj/hyp

Cos 45 = n/√6

√6 × √2/2 = n (cos 45 = √2/2)

√12/2 = n

√(4*3)/2 = n

(2√3)/2 = n

√3 = n

n = √3

Find the equation of a line that passes through the point (3,1) and has a gradient of -3. Leave your answer in the form y = m x + c

Answers

Answer:

[tex]y = (-3)\, x + 10[/tex].

Step-by-step explanation:

The question requires that the equation should be in the slope-intercept form [tex]y = m \, x + c[/tex]. The [tex]m[/tex] and [tex]c[/tex] in this equation are constants. In particular:

[tex]m\![/tex] would represent the slope of this line (also known as the gradient of this line,) whereas[tex]c[/tex] would be the [tex]y[/tex]-intercept of this line.

The question states that the slope of this line is [tex](-3)[/tex]. Therefore, [tex]m = -3[/tex]. Thus, the equation for this line should be in the form [tex]y = (-3)\, x + c[/tex].

The value of constant [tex]c[/tex] could be found using the other piece of information: the point [tex](3,\, 1)[/tex] is in this line. In other words, the solution [tex]\text{$x = 3$ and $y = 1$}[/tex] should satisfy the equation [tex]y = (-3)\, x + c[/tex].

Substitute [tex]\text{$x = 3$ and $y = 1$}[/tex] into the equation [tex]y = (-3)\, x + c[/tex] and solve for [tex]c[/tex]:

[tex]1 = (-3) \times 3 + c[/tex].

[tex]1 = -9 + c[/tex].

[tex]c = 10[/tex].

Hence, [tex]y = (-3) \, x + 10[/tex] would be the slope-intercept form of the equation of this line.

Write an expression in simplest form for the area of the rectangle.
Length: (c+4) ft
Width: 3 ft

Answers

Answer:

3c+12

Step-by-step explanation:

Are of rectangle = Length * Width

Given the following data

Length: (c+4) ft

Width: 3 ft

Area of the rectangle = 3 (c+4)

Expand

Area of the rectangle = 3(c) + 3(4)

Area of the rectangle = 3c  + 12

hence the expression in simplest form for the area of the rectangle is 3c+12

Answers

Answer:

the interest cost is $4,679.45

Step-by-step explanation:

The computation of the interest cost is shown below:

= Loan amount × rate of interest × given no of days ÷ total no of days in a year

= $40,000 × 14% × 305 days ÷ 365 days

= $4,679.45

hence, the interest cost is $4,679.45
