Answer:
option: D is correct. ( (D) a markup of 15% on selling price is equivalent to a 85% markup on cost ).
Step-by-step explanation:
" Markup is the percentage difference between a product's cost and its selling price "
Since we are asked to Convert a markup of 15% on selling price to its equivalent markup on cost.
As there is a markup of 15% on selling price. Hence the cost of the product would be (100-15)%=85% of the selling price.
<em>Hence, a markup of 15% on selling price is equivalent to a 85% markup on cost.</em>
<em>Hence, option D is true.</em>
The answer would be C. When you calculate the mean, it includes every number for a certain period of time into things and averages it out. The median does not average out all the numbers.
You would need to find the area of which the irrigation would cover:
Area of a circle=pi*r^2
=300^2*pi
=90000pi ft^2
Hope this helps
To Prove: ΔEFI ~ Δ GFH
Proof:
When two triangles are similar, their corresponding sides are Proportional and their corresponding interior angles are equal.
Two Triangles can be proven similar by following Similarity Criterion.
1. AA
2.SSS
3.SAS
→∠EFI=∠GFH-------[Vertically Opposite angles]
The Other statement which is needed to prove that triangles EFI and GFH are similar is
Option C:→ ∠E ≅ ∠G
So, Two triangles ΔEFI and Δ GFH are Similar by Angle-Angle(AA) Criterion.
