Mike bought shares of a brand-new corporation that manufactures dish antennas. He bought the stock years ago for S4,100. He recently sold this stock for 57,100. Express his capital gain as a percent of the original purchase price. Round your answer to the nearest tenth of aperient.
Answer:
73.2%
Step-by-step explanation:
The capital gain of $57100 with respect to the original purchase is 1292.68%.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths.
Given that,
Initial price = $4100
Final price = $57100
Percentage = (change in price)/(original price)
Percentage = (Final price - initial price)/(original price)
Percentage = (57100 - 4100)/4100
Percentage = 12.9268 ⇒ 1292.68%
Hence "The capital gain of $57100 with respect to the original purchase is 1292.68%".

Sewing patterns recommend buying extra fabric in case of mistakes. Jessica bought 6 yards of fabric, plus 15% extra fabric.
Derek bought 5 yards of fabric, plus 30% extra. Who bought more fabric? How much more?
Answer:
Jessica bought more fabric
Step-by-step explanation:
15% of 6 is 0.9 and 30% of 5 is 1.5 so 6+0.9 = 6.9 and 5+1.5 = 6.5 so Jessica bought 0.4 yards more than Derek.
can someone rewrite 6x + 2y = -144 as a slope intercept equation?
Answer:
y = -3x -72
Step-by-step explanation:
[tex]6x+2y=-144\\\\2y=-6x-144\\\\y=\frac{-6}{2}x-\frac{144}{2}\\\\y=-3x-72[/tex]
Solve this system by substitution 7x-y=3
y=x+3
Answer:
7x-y=3 (1)
y=x+3 (2)
Replace y = x + 3 in (1) => 7x- (x + 3) = 3
=> 6x-3 = 3 => x = 1 => instead of (2) => y = 4
So: x = 1, y = 4 is the solution of the system of equations

7. LX -(3z +4z) - (6z - 2)
Answer: LX - 13z - 2
Step-by-step explanation:
(3z + 4z)= 7z
LX - 7z - (6z - 2)
LX + -7z + -6z + -2
LX + -13z + -2
= LX - 13z - 2
A line passes through (8,-4) and has a slope of 3. What is the equation of the line?
Answer:
3x-y=28
Step-by-step explanation:
Point slope form:
y-y1=m(x-x1) where, (x1,y1) is the point given and m is the slope.
Answer:
y = 3x - 28
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3, thus
y = 3x + c ← is the partial equation
To find c substitute (8, - 4) into the partial equation
- 4 = 24 + c ⇒ c = - 4 - 24 = - 28
y = 3x - 28 ← equation of line
18 What is the equation of the line that is perpendicular to y = -x – 10 and contains point (-12, 1)? A y = X - 8 B y = - 15 C y = -x - 8 D y = 3*+ 17
Answer:
The equation of the line that is perpendicular to y = -x – 10 and contains point (-12, 1)
[tex]y=x+13[/tex]
Please note there is something wrong with the values given question. This is correct answer.
Step-by-step explanation:
Slope of line y = -x – 10 is m1=-1
Since slope of perpendicular lines are negative reciprocal of each other
Slope of other line is m2=1
Equation of line contains point (-12, 1) and having slope m2=1 is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-1 = 1(x+12)[/tex]
[tex]y =x+12+1 \\y = x + 13[/tex]

If 10,50,80 and x are in proportion,find the value of x
Given :
10,50,80 and x are in proportion.
To Find :
The value of x.
Solution :
It is given that 10,50,80 and x are in proportion.
It means that 10,50 and 80, x are same ratio.
[tex]R = \dfrac{10}{50}=\dfrac{80}{x}\\\\x = 400[/tex]
Therefore, the value of x is 100.
Jenny has $1,200 in her savings account. If the bank pays 3% interest per year on savings, how much interest does she earn in one year? A.$36 B.$360 C.$3.60 D.$3600
Given:
Principal value = $1200
Rate of interest = 3% per year
To find:
The interest earned by Jenny in one year.
Solution:
Formula of interest:
[tex]I=\dfrac{P\times r\times t}{100}[/tex]
Where, P is principal, r is rate of interest and t is time.
We have, P = 1200, r = 3, t=1. Putting these values, we get
[tex]I=\dfrac{1200\times 3\times 1}{100}[/tex]
[tex]I=\dfrac{3600}{100}[/tex]
[tex]I=36[/tex]
The interest earned by Jenny in one year is $36.
Therefore, the correct option is A.

A farmer raises sheep. The number of sheep in his flock changes from year to year. The number can be represented by the equation S=24(1.05)t where S is the total number of sheep in his flock and t is the number of years since he first started raising sheep. Which statement best explains the change in the number of sheep?
Answer:
It increases by 5% each year
Step-by-step explanation:
The function, S=24(1.05)t, models change in the Number of sheep over time, t.
The function represents an exponential growth model:
The function could be rewritten in the general form ;
y = Ab^x
y = number of comocafter t years
b = increase in initial amount ; b = (1 + x)
Comparing the function :
b = 1.05
b = 1 + r ; where r = rate
1.05 = 1 + r
r = 1.05 - 1
r = 0.05 = (0.05 * 100%). = 5%
It increases by 5% each year
What is the answer ?
Answer:
y=400x+0
or simply
y=400x
Step-by-step explanation:
Ok slope= Rise over run
Y-intercept= point where x is 0
y-intercept= (0,0)
slope= 400/1=400
m=slope
b=y-intercept
y=mx+b
y=400x+0
