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

There were five teams entered in a competition. Each team consisted of either only boys or only girls. The number of team members was 9, 15, 17, 19 and 21. After one team of girls had been knocked out of the competition, the number of girls still competing was three times the number of boys. How many girls were in the team that was eliminated?
Answer:
21.
Step-by-step explanation:
Since there were five teams entered in a competition, and each team consisted of either only boys or only girls, with the number of team members being 9, 15, 17, 19 and 21 members, if after one team of girls had been knocked out of the competition, the number of girls still competing was three times the number of boys, to determine how many girls were in the team that was eliminated, the following calculation must be performed:
9 + 15 + 17 + 19 = 60/4 = 15
9 + 15 + 17 + 21 = 62/4 = 15.5
9 + 15 + 19 + 21 = 64/4 = 16
9 + 17 + 19 + 21 = 66/4 = 16.5
15 + 17 + 19 + 21 = 72/4 = 18
Thus, since 15 x 3 equals 45, and 45 plus 15 equals 60, the number of girls on the team that was eliminated was 21.

Simplify each of the following:
Answer:
1. x⁴³/³⁵
2. 1/x⁶
3. x⁴/2
Step-by-step explanation:
1. ⁷√x³. ⁵√x⁴
The above expression can be simplified as follow:
Recall:
ᵐ√aⁿ = aⁿ/ᵐ
⁷√x³ × ⁵√x⁴ = x³/⁷ × x⁴/⁵
Recall:
aⁿ × aᵐ = aⁿ⁺ᵐ
x³/⁷ × x⁴/⁵ = x⁽³/⁷ ⁺ ⁴/⁵⁾ = x⁴³/³⁵
Therefore,
⁷√x³. ⁵√x⁴ = x⁴³/³⁵
2. x¯³ / x⁵x¯²
The above expression can be simplified as follow:
Recall:
aⁿ × aᵐ = aⁿ⁺ᵐ
x⁵x¯² = x⁵ ⁺ ⁽¯²⁾ = x⁵ ¯ ² = x³
Thus,
x¯³ / x⁵x¯² = x¯³ / x³
Recall:
aⁿ / aᵐ = aⁿ ¯ ᵐ
x¯³ / x³ = x¯³ ¯ ³ = x¯⁶
Recall
a¯ⁿ = 1/aⁿ
x¯⁶ = 1/x⁶
Therefore,
x¯³ / x⁵x¯² = 1/x⁶
3. 5(x⁴)³ / 10x⁸
The above expression can be simplified as follow:
Recall:
(aⁿ)ᵐ = aⁿ×ᵐ
5(x⁴)³ / 10x⁸ = 5x¹² / 10x⁸
Recall:
aⁿ / aᵐ = aⁿ ¯ ᵐ
5x¹² / 10x⁸ = (5/10)x¹² ¯ ⁸ = 1/2 x⁴ = x⁴/2
Therefore,
5(x⁴)³ / 10x⁸ = x⁴/2
simone buys a painting for 24000 later she sells it for 60000 how much is her percentage profit
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
percentage profit = 150%

A builder needs 30 centimeter lengths of lumber to reinforce a stud wall. How many can he cut from a piece that is five meters long? Write how you can figure it out.
Answer:
16
Step-by-step explanation:
5m is equivalent to 500cm
500 ÷ 30 = 16.6666666667
= 16
The number of the 30 cm lumbers will be equal to 16.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that a builder needs 30-centimetre lengths of lumber to reinforce a stud wall.
The number of the lumbers will be calculated as,
Total length = 5 m = 500 cm
Each lumber size = 30 cm
Number = 500 / 30
Number = 16.666
Therefore, the number of the 30 cm lumbers will be equal to 16.

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:
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 $4,679.45
Find the equation of a line that passes through the point (3,1) and has a gradient of -3. Leave your answer in the form y = m x + c
Answer:
[tex]y = (-3)\, x + 10[/tex].
Step-by-step explanation:
The question requires that the equation should be in the slope-intercept form [tex]y = m \, x + c[/tex]. The [tex]m[/tex] and [tex]c[/tex] in this equation are constants. In particular:
[tex]m\![/tex] would represent the slope of this line (also known as the gradient of this line,) whereas[tex]c[/tex] would be the [tex]y[/tex]-intercept of this line.The question states that the slope of this line is [tex](-3)[/tex]. Therefore, [tex]m = -3[/tex]. Thus, the equation for this line should be in the form [tex]y = (-3)\, x + c[/tex].
The value of constant [tex]c[/tex] could be found using the other piece of information: the point [tex](3,\, 1)[/tex] is in this line. In other words, the solution [tex]\text{$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.
