Answer:
Step-by-step explanation:
Let the cost price be = $ 100
Increased price = 100 * 30/100 = $30
Market price = 100 +30 = $130
Discount amount = 10% of 130 = 10/100 * 130 = $ 13
Price after discount = 130 - 13 = $ 117
Gain = 117 - 100 = 17
Gain = 17%
Given:
Center of a circle is at point C(-1,2).
AB is the diameter of the circle.
Coordinates of the point A are A(2,6).
To find:
The coordinates of point B.
Solution:
Let the coordinates of point B are (a,b).
If AB is the diameter of the circle, then A and B are end points of diameter of the circle and the center C is the midpoint of AB.
Point C = Midpoint of AB
On comparing both sides, we get
Similarly,
Therefore, the coordinates of point B are (-4,-2).
Answer:
31/12
Step-by-step explanation:
Step-by-step explanation:
So you Have to find the area of the shape
so you have to multiply 9x9 and 7x7
so it 81 and 49
so then you multiply it
81x49
3969 is your answer
C=3969
