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

D.)x= √6 or -√6

Answers

Answer:

C.) y is greater than or equal to -6

Step-by-step explanation:

The range are all the set of y-values that are plotted on the vertical axis (y-axis).

The range starts from -6 and above. Which is y ≥ -6

Therefore, range of the function is said to be:

3(5x - 6) = 6(2x - 12)

Answers

Answer:

x = -18

Step-by-step explanation:

Distribute: 3*5x = 15x ; 3*-6 = -18 ; 6*2x = 12x ; 6*-12 = -72

15x - 18 = 12x - 72

Add 18 to both sides: 15x = 12x - 54

Subtract 12x from both sides: 3x = -54

Divide both sides by 3: x = -18

Answer:

x= 17.666666...

Step-by-step explanation:

3(5x - 6) = 6(2x - 12)

(3 times 5x , 3 times  -6)             (6 times 2x, 6 times - 12)

15x-18 = 12x -72           (multiply insides)

-12x       -12x              (remove 12x from right side)

3x-19 = -72                (product)

   +19 = +19                (add 19 left side to remove it)

3x = 53                        (product)

x = [tex]\frac{53}{3}[/tex]                              (divide)

x= 17.666666...                (answer)

x = 17.67                     (if simplify)

Mel took out a loan of $40,000 at 14 percent on March 16, 2015 which will be due on January 9, 2016. Using exact interest the amount of Mel's interest cost is:

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

When solving a system of linear equations what are you looking for?

Answers

A system of linear equations contains two or more equations, for example: y = 0.5x + 2 and y = x-2. The solution of such a system is the ordered pair which is a solution to both equations. To solve a system of linear equations graphically, we graph both equations in the same coordinate system.

Answers

Answer:

percentage profit = 150%

Step-by-step explanation:

percentage profit = sp - cp/cp * 100

sp is the selling price = 60000

cp is the cost price = 24000

percentage profit = 60000-24000/24000 * 100

percentage profit = 36000/24000 * 100

percentage profit = 36000/240
