What is depreciation?The monetary value of an asset decreases over time due to use, wear and tear or obsolescence. This decrease is measured as depreciation.
What is compound interest for depreciation?If the reduced value of the goods is compounded for fixed time then it is called compound depreciation.
Formula of compound interest for depreciation:
[tex]A = P(1-\frac{r}{100} )^{n}[/tex]
Where,
A= Final Amount
P = initial Principal
n = time in years
r = rate per annum
According to the question
New copier costs (p) = $10,000
depreciates in value every year (r) = 15%
The principal will replace the copier when it drops below 10% of its original value.
i.e Final amount should be less than [tex]$10,000 * \frac{10}{100}[/tex]
A is < $ 1000
Using compound interest formula :
[tex]A = P(1-\frac{r}{100} )^{n}[/tex]
[tex]1000 > 10000(1-\frac{15}{100} )^{n}[/tex]
[tex]0.1 > (0.85 )^{n}[/tex]
n ≈ 14.168
n = after 15years (next whole no)
Hence , The solution set for the inequality is (15, ∞).

for a certain online store, the distribution of number per hour is approximately normal with mean 1200 purchases and standard deviation 200 purchases. for what proportion of hours will the number of purchases at the online store exceed 1400?
a)5%
b)68%
c)16%
d)32%
Answer: 16%
Step-by-step explanation:
When we have a normal distribution, the 100% of our sample will be placed in a "gaussian bell".
Where the middle of this bell coincides with the mean.
The mean, in this case, is 1200, and the standard deviation is 200.
In the image below you can see that between the points.
Mean + standard deviation and the end of the graph, we have:
13.5% + 2.35% + 0.15% = 16%
And particularly, if we want to know the percentage that exceed 1400, will be the same percentage above the mean plus the standard deviation.
mean = 1200
SD = 200
mean + standard deviation = 1200 + 200 = 1400.
Then the percentage that exceeds 1400 is equal to the percentage that we found above, then the correct option is C: 16%

[tex]x=7[/tex]
Step-by-step explanation:
[tex]\sqrt{3x+8}=\sqrt{4x+1}[/tex]
Square both sides:
[tex](\sqrt{3x+8})^{2} =(\sqrt{4x+1})^{2}[/tex]
[tex]3x+8=4x+1[/tex]
Subtract 8 from both sides:
[tex]3x+8-8=4x+1-8[/tex]
[tex]3x=4x-7[/tex]
Subtract 4x from both sides:
[tex]3x-4x=4x-7-4x[/tex]
[tex]-x=-7[/tex]
Divide both sides by -1:

The m∠P is three less than twice the measure of ∠Q. If ∠P and ∠Q are supplementary angles, find the measures of both angles.
Answer:
m∠P =119
m∠Q = 61
Step-by-step explanation:
m∠P = 2(∠Q)-3 or p=2(q)-3
supplementary angles so they combine to equal 180!
soooooo we can take
q+p=180
input what p equals and you get
q+ 2(q)-3=180
3q-3=180
3q=183
q=61
now we have what m∠Q is, so just subtract that from 180 to get m∠P
180-61=119

Juanita is converting 7 meters to inches. Will the number of inches be less than or greater than 7? choose one of these answers below
The number of inches will be less than 7 because 7 is a small number.
The number of inches will be greater than 7 because 7 is a small number.
The number of inches will be less than 7 because inches are smaller than meters.
The number of inches will be greater than 7 because inches are smaller than meters.
Answer:
The number of inches will be greater than 7 because inches are smaller than meters.
Step-by-step explanation:
Step-by-step explanation:
1 inch is around 2.54cm, which is a lot less than 1 meter.
Since inches are a smaller unit than meters, the number of inches will be greater than 7 to have the same equivalent length.
"The number of inches will be greater than 7 because inches are smaller than meters" is correct.

Karla will walk her bike at a speed of 6 mile/hour from her house to the bike
shop, which is 2.5 mi from her house, to get the bike fixed. She expects to
wait 30 min for the repair. Then she will return home by riding her bike at a
speed of 15 miles/hour. How long will the entire trip last? *
A. 1.30 hours
B. 1.50 hours
C. 0.50 hour
D. 1.08 hours
Answer:
D. 1.08 hours
Step-by-step explanation:
Speed = distance / time
Going to the bike shop
speed = 6 mile/hour
Distance = 2.5 mi
Time = t
Speed = distance / time
6 = 2.5 / t
Cross product
6t = 2.5
Divide both sides by 6
t = 2.5/6
= 0.417 hour
She waited for 30 minutes for the repair, that is 0.5 hour
Going back home
Speed = 15 miles/hour
Distance = 2.5 mi
Time = t
Speed = distance / time
15 = 2.5 / t
Cross product
15t = 2.5
Divide both sides by 15
t = 2.5 / 15
= 0.167 hour
Total time of the entire trip =
0.417 hour + 0.5 hour + 0.167 hour
= 1.084 hour
Approximately 1.08 hour
The correct answer is D. 1.08 hours
5x +7 y=-17
4x – 3y = -5
Substitute.
Answer:
(x,y) = (-2, -1)
Step-by-step explanation:
We start off by substituting the value of "x".
5x+7y=-17
x=-[tex]\frac{5}{4} + \frac{3}{4}y[/tex]
We then solve 5[tex]5(-\frac{5}{4}+\frac{3}{4}y ) +7y= -17[/tex]
y=-1 *Substitute the value of "y"
x= -[tex]-\frac{5}{4}+\frac{3}{4}x(-1)[/tex]
x=-2
[tex]\left \{ {{-17=-17} \atop {-5=-5}} \right.[/tex] This works.

Consider the these two linear equations:
10x + 5y = 90
y = ax + 18
What value of a will make the two lines parallel?
Answer:
a = -2
Step-by-step explanation:
The first equation can be rewritten in slope-intercept form:
5y = -10x +90
y = -2x +18
The value a=-2 will make the second line identical to the first.

The width of a rectangle is 5 feet less than the length. The perimeter is 62. Find the length and width of the rectangle.
Variables: ___________________________
Model equation: ______________________________
Length of the rectangle: ______________________________
Width of the rectangle: ______________________________
Perimeter formula: p = 2(w + l)
The perimeter is 62.
p = 62
The width of a rectangle is 5 feet less than the length.
w = l - 5
Substitute and solve.
62 = 2[(l - 5) + l)]
62 = 2l + 2l - 10
62 = 4l - 10
72 = 4l
18 = l
Substitute and solve for the width
w = 18 - 5
w = 13
Therefore, the length is 18 and the width is 13.
Best of Luck!
Answer:
see below and attached.
Step-by-step explanation:
Perimeter (P) = 2 L (Length) + 2 W (Width)
where P = 62
W = L - 5
P = 2L + 2W
62 = 2L + 2(L -5)
62 = 2L + 2L - 10
72 = 4L
L = 72/4
L = 18
W = L - 5
W = 18 - 5
W = 15
Variables : P, L, W
Model equation: P = 2L + 2W
Length of the rectangle: 18
Width of the rectangle: 13
