According to the given problem,
(i) It is given that,
The cost price of 1000 packets of peanuts = Rs. 50
We need to find the cost price of 1 packet of peanut = [tex]\frac{50}{1000}[/tex] = Rs. 0.05
(ii) Selling price at which Sipho continues to sell 1 packet = Rs. 1
Then Selling price of 1000 packets = 1000 x 1 = Rs. 1000
Then Profit made by sipho = Selling Price - Cost Price
= 1000 - 50
= Rs.950
Profit percentage gained by Sipho = [tex]\frac{Profit}{Cost Price}[/tex] x 1000
= [tex]\frac{950}{50}[/tex] x 1000
= 1900 %
(iii) The profit earned by sipho remains same, we nee to find the cost price at which Sipho should sell 100gm of her peanuts is Rs. 1

The listed price of the pair of pants was $38, but the price with tax came to $39.14. Find the percent sales tax.
well, the difference is 39.14 - 38 = 1.14, so that's the tax.

Which sequence exhibits the similarity between rectangles ABCD which A’B’C’D’ shown in the coordinates plane below
The sequence of transformation that exhibits the similarity between the rectangles ABCD and rectangle A'B'C'D' is the option C.
C. Rectangle ABCD is reflected across the y-axis and then dilated by a scale factor of 2 with the center of dilation at the origin to obtain rectangle A'B'C'D'
What is a reflection transformation in geometry?A reflection transformation of an object gives or produces the mirror image of the object about a specified line.
The coordinates of the points of the rectangle ABCD obtained from the graph are; A(-4, -4), B(-4, 4), C(2, 4), and D(2, -4).
The coordinates of the image of the rectangle ABCD (rectangle (A'B'C'D') are; A'(8, -8), B'(8, 8), C'(-4, 8) and D'(-4, -8)
The coordinates of the reflection of the point (x, y), following a reflection across the y-axis is the point (-x, y)
The vertices of the image of rectangle ABCD formed following a reflection across the x-axis are therefore;
A(-4, -4) [tex]\underrightarrow{R_{x-axis}}[/tex] A''(4, -4)
B(-4, 4) [tex]\underrightarrow{R_{x-axis}}[/tex] B''(4, 4)
C(2, 4) [tex]\underrightarrow{R_{x-axis}}[/tex] C''(-2, 4)
D(2, -4) [tex]\underrightarrow{R_{x-axis}}[/tex] D''(-2, -4)
The coordinates of the point (x, y) following a dilation by a scale factor of k, with the center of dilation at the origin is (k·x, k·y)
The dilation of the image of the rectangle ABCD by a scale factor of 2 gives;
A''(4, -4) [tex]\underrightarrow{D_{2}}[/tex] (2×4, 2×(-4)) = A'(8, -8)
B''(4, 4) [tex]\underrightarrow{D_{2}}[/tex] (2×4, 2×(4)) = B'(8, 8)
C''(-2, 4) [tex]\underrightarrow{D_{2}}[/tex] (2×(-2), 2×(4)) = C'(-4, 8)
D''(-2, -4) [tex]\underrightarrow{D_{2}}[/tex] (2×(-2), 2×(-4)) = D'(-4, -8)
The points of the image of rectangle ABCD following a a reflection and a dilation are A'(8, -8), B'(8, 8), C'(-4, 8) and D'(-4, -8), which are the same as the coordinates of the points of the given rectangle A'B'C'D'

The manufacturing process of a particular rugby ball consists of two parts, a leather covering and a rubber bladder. The probabilities of defect in the leather covering is 5% and the probability of the rubber bladder is 15% respectively. What is the probability that the assembled Rugby ball will not have any defect.
Let A and B denote the event that a rugby ball is defective due to defects in the leather covering and the rubber bladder respectively.
Then we can say that P(A) = 5 / 100 = 1 / 20 and
P(B) = 15 / 100 = 3 / 20
Therefore P(A') = 1 - 1/20 = 19/20 and P(B') = 1 - 3 / 20 = 17 / 20.
P(A') and P(B') gives us the probabilities that the rugby ball will not have defective parts respectively.
Therefore the probability that the assembled product will not have any defect is:
P(A') × P(B')
[tex]=\frac{19}{20} \times \frac{17}{20}\\\\=\frac{323}{400} \\\\=0.8075[/tex]

a gardener has 760 feet of fencing to fence in a rectangular garden. one side of the garden is bordered by a river and so it does not need any fencing.
The dimensions that would guarantee that the garden has the greatest possible area is 190 feet on the shorter side and 380 feet on the longer side to produce an area of 72,200 square feet.
A dimensions of a rectangle is the length of each side.
Let x = length of the shorter side
y = length of the longer side
If one side of the garden is bordered by a river and so it does not need any fencing, and assume that the longer side is this side, then the perimeter that only needs to be fenced by 760 feet of fencing materials is
2x + y = 760
y = 760 - 2x
The area of the rectangular garden is the product of the shorter side and the longer side of the garden. Hence,
A = xy
A = x(760 - 2x)
A = 760x - 2x²
To obtain the largest area possible, the first derivative of the area should be equal to zero.
A(x) = 760x - 2x²
A'(x) = 0
760 - 4x = 0
Solve for x.
760 - 4x = 0
4x = 760
x = 190
length of the shorter side = 190 feet
y = 760 - 2x
y = 760 - 2(190)
y = 380
length of the longer side = 380 feet
Solve for the greatest possible area.
A = xy
A = 190 feet(380 feet)
A = 72,200 square feet

Find the points on the graph of[tex]x^{2/3}[/tex] + [tex]y^{2/3}[/tex] = 1 where the tangent line has slope 1
Any point satisfying the relation y = -[1 - (∛x²)]²(1/(∛x)) will be points on the graph where the tangent line has slope 1.
What is the slope of a given line?
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.
Consequently, the formula for the change in y-coordinate with respect to the change in x-coordinate is the slope of a line is represented by the expression m = change in y/change in x =Δy/Δx.
Additionally, the slope of the line can be shown as tan θ = Δy/Δx
So, the slope of a line is tan θ.
The given equation is: (∛x²) + (∛y²) = 1
Therefore, (∛y²) = 1 - (∛x²) ⇒ y² = [1 - (∛x²)]³
Differentiating the equation formed with respect to x, we get
2y(dy/dx) = 3[1 - (∛x²)]²(-2/3)(1/(∛x)) ⇒ dy/dx = (-1/y)[1 - (∛x²)]²(1/(∛x)) -(i)
Given, the slope of the tangent line is = 1 -(ii)
Thus, equating (i) and (ii), we get,
(-1/y)[1 - (∛x²)]²(1/(∛x)) = 1 ⇒ y = -[1 - (∛x²)]²(1/(∛x))
Therefore any point satisfying the relation y = -[1 - (∛x²)]²(1/(∛x)) will be points on the graph where the tangent line has slope 1.

The equation of the line that passes through point (-3,1) and perpendicular to y=-5x+2 is y = (1/5)x + 8/5.
What is the equation of line that passes through the given points and is perpendicular to the given line?Given the data in the question;
Equation of line: y = -5x + 2Point: (-3,1)First we determine the slope of the initial line using the slope intercept-form. y = mx + b
y = -5x + 2
Compared with the slope intercept form,
Slope m = -5
Now, for the equation of line perpendicular to the initial line, its slope must be a negative reciprocal of the initial slope.
Hence, slope of the perpendicular line is;
Slope m = -1/(-5) = 1/5
To find the equation of the perpendicular line, we use the point slope formula.
y - y₁ = m( x - x₁ )
Plug in the slope m ( 1/5) and point (-3,1).
y - 1 = (1/5)( x - (-3) )
y - 1 = (1/5)( x + 3 )
Convert to slope-intercept form.
y - 1 = (1/5)( x + 3 )
y - 1 = x/5 + 3/5
y = x/5 + 3/5 + 1
y = x/5 + 3/5 + 1
y = x/5 + 8/5
y = (1/5)x + 8/5
Therefore, the equation of the perpendicular line is y = (1/5)x + 8/5.
