Answer: An article was sold at a 20% discount, at Rs. 400. What was its marked price?
Let M denotes the required marked price of the given article.
Hence from above data we get following relation,
(1 - 20/100)*M = 400
or (4/5)*M = 400
or M = (5/4)*400 = 500 (Rs) [Ans]
Step-by-step explanation:
The answer to this question is area=length*width

Answer:
Maria needs 3 lengths of gutter of finish the shed.
Step-by-step explanation:
We need to calculate the perimeter of the rectangular shed to know how much 5 feet gutter is needed.
The perimeter of the shed is p = 2(l + b) where l = 10ft and b = 9 ft
p = 2(10 + 9) = 2(19) = 38 ft
Now, the perimeter of the shed also equal 23 ft of gutter already installed plus 5x ft gutter where x = number of gutters.
So 23 + 5x = 38
collecting like terms, we have
5x = 38 - 23
5x = 15
dividing through by 5 we have
5x/5 = 15/5
x = 15/5
x = 3
So, Maria needs 3 lengths of gutter of finish the shed.
Answer:
The equilibrium point is at x = 6
Step-by-step explanation:
Given
![Demand (q) = \frac{18}{x}](https://tex.z-dn.net/?f=Demand%20%28q%29%20%3D%20%5Cfrac%7B18%7D%7Bx%7D)
![Supply (q) = \frac{x}{2}](https://tex.z-dn.net/?f=Supply%20%28q%29%20%3D%20%5Cfrac%7Bx%7D%7B2%7D)
Required
Determine the equilibrium point
The equilibrium point is determined by
![Demand = Supply](https://tex.z-dn.net/?f=Demand%20%3D%20Supply)
Substitute values for Demand and Supply
![\frac{18}{x} = \frac{x}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7Bx%7D%20%3D%20%5Cfrac%7Bx%7D%7B2%7D)
Cross Multiply
![x * x = 18 * 2](https://tex.z-dn.net/?f=x%20%2A%20x%20%3D%20%2018%20%2A%202)
![x^2 = 36](https://tex.z-dn.net/?f=x%5E2%20%3D%2036)
Take positive square root of both sides
![x = 6](https://tex.z-dn.net/?f=x%20%3D%206)
Hence;
<em>The equilibrium point is at x = 6</em>
