a man buys eggs at RS 9.60 per dozen and sell 20 eggs for RS 18 what is his gain or loss percen?
Answer:
Percentage Gain = 12.5%
Step-by-step explanation:
Given
[tex]Cost\ Prize = 9.60[/tex] per dozen
[tex]Selling\ Price = 18[/tex] per 20
Required
Determine the percentage gain or loss
First, we have to calculate the unit cost price and the unit selling price.
If a dozen costs 9.60
Then 1 costs
[tex]Cost = 9.60/12[/tex]
[tex]Cost = 0.80[/tex]
If he sells 20 for 18
Then he sells 1 for:
[tex]Sell = 18/20[/tex]
[tex]Sell = 0.9[/tex]
The percentage change is then calculated as:
[tex]\%Change = \frac{Sell - Cost}{Cost} * 100\%[/tex]
[tex]\%Change = \frac{0.9 - 0.8}{0.8} * 100\%[/tex]
[tex]\%Change = \frac{0.1}{0.8} * 100\%[/tex]
[tex]\%Change = \frac{0.1 * 100\%}{0.8}[/tex]
[tex]\%Change = \frac{10\%}{0.8}[/tex]
[tex]\%Change = 12.5\%[/tex]
Because the percentage change is positive, then he made a gain.
Hence:
Percentage Gain = 12.5%

Write the standard form of the equation of the circle with center (−7,1) that passes through the point (−7,9).
Answer:
(x + 7)² + (y - 1)² = 64
Step-by-step explanation:
Use the equation of a circle, (x - h)² + (y - k)² = r²
Plug in the point and center, then solve for r:
(x - h)² + (y - k)² = r²
(-7 + 7)² + (9 - 1)² = r²
0 + 64 = r²
64 = r²
8 = r
Then, plug in the center and r² into the equation:
(x + 7)² + (y - 1)² = 64
So, (x + 7)² + (y - 1)² = 64 is the standard form of the circle's equation

Which solution value satisfies the inequality x – 6 ≥ –7?
Question 18 options:
A)
x = –5
B)
x = 0
C)
x = –2
D)
x = –7
Answer:
B) x = 0
Step-by-step explanation:
To find the solution value that satisfies the inequality x – 6 ≥ –7, you must plug every x value into the x and see which one works.
Plug -5 into x
-5 – 6 ≥ –7
Combine like terms
-11 ≥ –7
This is false, -11 is not greater than or equal to -7.
Plug 0 into x
0 – 6 ≥ –7
Combine like terms
– 6 ≥ –7
This is true, -6 is greater than -7.
Plug -2 into x.
-2 – 6 ≥ –7
Combine like terms
-8 ≥ –7
This is false, -8 is not greater than or equal to -7.
Plug -7 into x.
-7 – 6 ≥ –7
Combine like terms
-13 ≥ –7
This is false, -13 is not greater than or equal to -7.
B) x = 0 is the only solution that is true and works, so that is your answer.

What is the unit price if 4 pounds of fruit
cost $6.487
the table represents a linear function.
a) -8
b) -4
c) 2
d) 5
Answer:
b. -4
Step-by-step explanation:
Every time one x value increases the y value decreases by 4. In the x values shown the number that should come after -4 is -3 so the y values -2 and -2 that are 8 units apart should be halved and be -4. This function maintains a constant rate of change throughout the function.

What is the median of the following data values?
98, 102, 53, 60, 22
=================================================
Explanation:
Sort the values from smallest to largest.
You should get {22, 53, 60, 98, 102}
The middle most value is 60, so this is the median.
If you wanted, you can cross off the outermost pair of values (22 and 102) to end up with {53, 60, 98} to help see the middle better.
----------
Another approach:
We have n = 5 items in the sorted set {22, 53, 60, 98, 102}
The middle-most value is in slot 3 since n/2 = 5/2 = 2.5 which rounds up to 3. The value in slot 3 is 60, so this is the median. This trick only works when we have an odd number of values.
Answer: the median is 60
Step-by-step explanation: It is 60 because in order to find the mean you have to put all the numbers in order from least to greatest.
22,53,60,98,102.
after doing this you have to see how many quantity of data will pair up and the one that is left in the middle is the median. In other words you have 5 data sets in this example, 22 and 102 will be a pair and so will 53 and 98 which would leave 60 in the middle with no pair hence 60 would be the median

Montraie drove 220 miles in 5 hours. If he continued at the same rate, how long would it take to travel 88 miles?
Answer:
2 hours
Step-by-step explanation:
220/5=44 miles an hour
88/44=2
2 hours
The solution is 2 hours
Total time it will take Montraie to travel a distance of 88 miles is 2 hours
What is Speed?
Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the total time for Montraie to drive 88 miles be = A
The distance traveled by Montraie be D
The value of D = 220 miles
The time taken by Montraie to travel 220 miles is T = 5 hours
Now , the speed of Montraie S = distance traveled by Montraie / time taken by Montraie
Substituting the values in the equation , we get
The speed of Montraie S = 220 / 5
The speed of Montraie S = 44 miles per hour
Now , the distance traveled by Montraie = 88 miles
So , the time taken by Montraie to travel 88 miles = distance traveled by Montraie / speed of Montraie S
Substituting the values in the equation , we get
The time taken by Montraie to travel 88 miles = 88 / 44
The time taken by Montraie to travel 88 miles A = 2 hours
Therefore , the value of A is 2 hours
Hence , The total time it will take Montraie to travel 88 miles is 2 hours

Draw AABC with vertices at A(1,6), B(1, 1) and C(5, 1). In this triangle, AB2 + BC2 = AC².
Next, use the GeoGebra tools to draw ADEF such that AB = DE, m/E = 90°, and
EF = BC.
Paste a picture of your drawing in the answer box
The triangle ABC drawing, which has vertices at A (1,6), B (1,1), and C (5,1) is shown below.
A triangle is the most basic form for a polygon with three sides and three vertices. Triangles are divided into various groups using their sides and angles. The triangle's total angle is always equal to 180 degrees, which is an interesting triangle fact (straight angle).
It is common knowledge that a triangle is a type of polygon with three edges and three vertices.
A, B, and C are frequently used to denote its vertices, making it one of the most important shapes in geometry.
A (1,6), B (1,1), and C (5,1) will be picked as the points. 〖〖AB〗^2+ 〖BC〗^2= AC〗^2
Hence, the image of the triangle ABC's design, which has vertices at A (1,6), B (1,1), and C (5,1) is linked above.
