a man buys a car for 80000 Rs 20,000 more for repairing he sells it for rupees 125000 find its gain
Answers
The man buys the car for 80000 units.
For repairing the car, the man spends 20000 units.
The man sells the car for 125000 units.
To find:
The gain percent of the man.
Solution:
The man buys the car for 80000 units.
For repairing the car, the man spends 20000 units.
∴ Total expenditure of the man for the car_
(80000 + 20000) units.
= 100000 units.
The man sells the car for 125000 units.
∴ Gain = (125000 - 100000) units
= 25000 units.
∴ Gain % = (25000×100)/100000
= (25000/1000)
= 25 %.
∴ The gain of the man is 25 %

What system of equations represents this situation?
Answers
Answer:
Jada's amount: 7h = m
Andre's amount: 4h + 9 = m
h = hours
m = money (total cost)
The system of equations that represents the situation is yx = y.
Step-by-step explanation:
The system is yx = y, since the amount of dollars per hour multiplied by the amount of hours, plus any amount (if needed) will equal the total amount of money that Jada and/or Andre receives.

Graph 3: modest positive correlation
Graph 4: strong positive correlation
Graph 5. weak negative correlation
Step-by-step explanation:
If i'm wrong PLEASE correct me
The graph first is perfect negative correlation, graph second is the modest negative correlation.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
As we know, the coefficient of correlation varies between -1 and +1.
If r = +1 (means the relation between the variable is strong and positive)
If r = -1 (means the relation between the variable is strong but negative)
As we can see in the graph, the line goes down represents the negative correlation and the line goes up represents the positive correlation.
So, we can say:
The first graph is perfect negative correlation.
The second graph is modest negative correlation.
The third graph is modest positive correlation.
The fourth graph is strong positive correlation.
The fifth graph is weak negative correlation.
Thus, the graph first is perfect negative correlation, graph second is the modest negative correlation.

Answer:
A. y = -1/4x + 1 1/2
B. The rate of change is losing/decreasing -1/4 (y axis unit) per (x axis unit)
Step-by-step explanation:
A. Your equation is 2x + 8y = 12
so solve this for y like any other other question. Start by subtracting 2x from both sides: 8y = -2x + 12
then divide both sides by 8 to isolate y: y = -2/8x + 12/8
simplify your equation: y = -1/4x + 3/2
turn 3/2 into a mixed fraction: y = -1/4x + 1 1/2
B. The rate of change is the same thing as the slope but you say it with units. I cant see a scenario but you can say something like:
The rate of change is losing/decreasing -1/4 (y axis unit) per (x axis unit)

Answer:
x = 32, y = 51
Step-by-step explanation:
You know the longest side of ΔTUS is 13m and the longest side of ΔMNP is (2x-y). Thus:
2x - y = 13 --- Equation 1
You know the sum of angles in a triangle is 360°. Two of the angles are given in ΔMNP (142° & 24°) and the remaining angle is (2x-50)°. Thus:
142 + 24 + 2x - 50 = 180
2x + 116 = 180
2x = 180 - 116
2x = 64
x = 64 ÷ 2
x = 32 --- Equation 2
Substitute x = 32 into Equation 1:
2(32) - y = 13
64 - y = 13
-y = 13 - 64
= -51
y = 51 --- Equation 3
Answer:
x = 32, y = 51
Step-by-step explanation:
Since the triangles are congruent then corresponding angles and sides are congruent, then
∠ U = ∠ N and NP = US
Require to find ∠ N
∠ N = 180° - (24 + 142)° ← sum of angles in triangle
= 180° - 166°
= 14°
Thus
2x - 50 = 14 ( add 50 to both sides )
2x = 64 ( divide both sides by 2 )
x = 32
and
NP = US
2x - y = 13 ← substitute x = 32
2(32) - y = 13
64 - y = 13 ( subtract 64 from both sides )
- y = - 51 ( multiply both sides by - 1 )
y = 51

Test Number of Words Time(minutes)
A. 30. 4
B. 78. 15
C. 99. 22
Answer:
Step-by-step explanation:
To calculate Zane's unit rate/number of words per minute for which each test, we divide number of words in each test by time taken for that test
For test A, unit rate = 30 words/ 4 minutes = 7.5 words per minute
For test B, unit rate = 78 words/15 minutes = 5.2 words per minute
For test C, unit rate = 99 words/22 minutes= 4.5 words per minute
From the above Zane has the highest unit rate in test A and is therefore fastest in test A
Write an equation in point slope form of the line that passes through the point (2,-8) and had a slope of 4
Answers
Plug those in
Solution: y + 8 = 4(x - 2)
The equation of a line in point-slope form is (y + 8) = 4(x - 2).
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, A line passes through the point (x₁, y₁) ⇒ (2,-8) and had a slope of 4.
We know the equation of a line in point-slope form is (y - y₁) = m(x - x₁).
∴ The equation of this line is (y + 8) = 4(x - 2).

Lines a, b, and c lie on the same coordinate plane. Line a is perpendicular to line b and intersects at (3, 6). Line b is perpendicular to line c, which is the graph of y = 2x + 3.
Write the equations of lines a and b.
Answers
Answer:
The answer is below
Step-by-step explanation:
The equation of a straight line is given as y = mx + b, where m is the slope and b is the y intercept.
Given that the equation of line c is y = 2x + 3, and line b is perpendicular to line c. Two lines are perpendicular if the product of their slope is -1. We can see that the slope of line c is 2, let [tex]m_1[/tex] be the slope of line c, hence:
[tex]2*m_1=-1\\\\m_1=\frac{-1}{2}[/tex]
Also, line b passes through (3, 6), hence the equation of line b is:
[tex]y-y_1=m_1(x-x_1)\\\\y-6=\frac{-1}{2}(x-3)\\\\y-6= \frac{-1}{2}x+\frac{3}{2}\\\\y=\frac{-1}{2}x+ \frac{15}{2}[/tex]
Line b has a slope of -1/2, and is perpendicular to line a, let [tex]m_2[/tex] be the slope of line a, hence:
[tex]\frac{-1}{2} *m_2=-1\\\\m_2=2[/tex]
Also, line a passes through (3, 6), hence the equation of line a is:
[tex]y-y_1=m_1(x-x_1)\\\\y-6=2(x-3)\\\\y-6=2x-6\\\\y=2x[/tex]

B. twice the area of the square
C. three times the area of the square
D. the area of the square.
4. Find the area Molly needs to paint.
Answers
Part 1) The surface that is shared by the two solids is the top of the cube that is the same that the square base of the pyramid
Part 2) The dimensions of this surface are 6 in x 6 in
Part 3) Molly needs to paint 228 square inches
Step-by-step explanation:
The picture of the question in the attached figure
Part 1) Which surface is shared by the two solids?
we know that
The surface that is shared by the two solids is the top of the cube that is the same that the square base of the pyramid
Part 2) What are the dimensions of this surface?
The surface is a square with side length 6 inches
so
The dimensions of this surface are 6 in x 6 in
Part 3) what is the area molly needs to paint?
we know that
The area that Molly needs to paint is equal to the surface area of the cube plus the surface area of the pyramid minus two times the area of the surface that is shared by the two solids
so
therefore
Molly needs to paint 228 square inches
