Answer:
25%
Step-by-step explanation:
Let the original price of A pair of skis be $100
discount given on A pair of skis = 20% on original price
discount value of A pair of skis in $ = 20% * $100
= (20 * 100)/100 = $20
discounted price of A pair of skis = original price - discount = 100 -20 = $80
in order to increase discounted price to original price of $100
there must be increase of $20 to discounted price which is $80
percentage increase on discounted price to return to the original price =
![(increased \ amount / discounted \ price) * 100 \\=>( 20/80) * 100 = 25\\](https://tex.z-dn.net/?f=%28increased%20%5C%20amount%20%2F%20discounted%20%5C%20price%29%20%2A%20100%20%5C%5C%3D%3E%28%2020%2F80%29%20%2A%20100%20%3D%20%2025%5C%5C)
therefore 25% must be increase on discounted price to return to the original price
Answer:
A) 1/3 D) 13/39 E) 14/42
Step-by-step explanation:
hope this helps. brainliest please.
ΔABC is a 45 - 45 - 90 triangle. The pattern of its sides is as follows:
Each leg = 1 unit (and both legs are that way, since the triangle is isosceles - so two sides are the same)
Hypotenuse = √2 units.
So if we know either leg, we multiply by √2 to get the hypotenuse. In reverse, we divide by √2 if we know the hypotenuse to get the measurement of a leg.
Our problem tells us that the hypotenuse AC is 10 units. We divide 10 by √2 to get the measurement of leg AB. Since it's a 45 -45 - 90 triangle, AB = BC.
![AB = \frac{10}{\sqrt{2}}](https://tex.z-dn.net/?f=%20AB%20%3D%20%5Cfrac%7B10%7D%7B%5Csqrt%7B2%7D%7D%20%20%20%20%20%20%20%20)
to rationalize the radical
![= \frac{10\sqrt{2}}{2} = 5\sqrt{2}](https://tex.z-dn.net/?f=%20%3D%20%5Cfrac%7B10%5Csqrt%7B2%7D%7D%7B2%7D%20%3D%205%5Csqrt%7B2%7D%20%20%20%20)
Thus, each leg is 5\sqrt{2} [/tex].
Answer= x^2-4
