Answer:
The marked price of an article is Rs. x, and selling price is Rs. y
Price difference = Rs. (x−y)
Now, on Rs. x, there is a discount of Rs. (x−y)
Thus, on Rs. 100, there will be a discount of Rs.
x
(x−y)
×100%.
Two shapes.. a circle and a rectangle. The width of the rectangle serves as the diameter of the circle.
Length = 140 m ; Width = 68 m
Circumference of a circle = 2 π r
circumference of a cirlce = 2 * 3.14 * (68m/2) = 2 * 3.14 * 34 m = 213.52
length = 2 * 140 m = 280 m
perimeter of the oval = 213.52 m + 280 m = 493.52 m
Answer:
A = 4a² - 4ab + b²
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the side length ) , so
A = (2a - b)² ← expand using FOIL
= (2a)² - 2ab - 2ab + (- b)²
= 4a² - 4ab + b²
16 + 4 • 5 – 6 ÷ 2 =
= 16 + 20 - 3
= 16 + 17
= 33
