A store has clearance items that have been marked down by 40%. They are having a sale, advertising an additional 45% off clearan

Olegator [25]

Answer:

$P_2 = (1-0.45) *0.6 P_o =0.55*0.60 P_o=0.33 P_o$

So the discount is 33% and we are paying 67% of the value. The reason is given by the relative change:

$\% Change = \frac{|0.33P_o -P_o|}{P_o}*100 =67\%$

Step-by-step explanation:

First we have a first discount of 40% so then using this condition and assuming that $P_o$ represent the initial price, the price after the first discount $P_1$ is given by:

$P_1 = (1-0.4) P_o =0.6P_o$

That means 60% of the original value.

Now we have another discount of 45% for the 60% reamining after a 2 discount so let's $P_2$ represent the price after the second disccount we can can express this price in terms of $P_1$ or $P_o$ liek this:

$P_2 = (1-0.45) P_1=0.55 P_1$

$P_2 = (1-0.45) *0.6 P_o =0.55*0.60 P_o=0.33 P_o$

So the discount is 33% and we are paying 67% of the value. The reason is given by the relative change:

$\% Change = \frac{|0.33P_o -P_o|}{P_o}*100 =67\%$

If segment EF = 6 and segment FG = 3, which of the following statements are enough to prove that triangles EFI and GFH are simil

klemol [59]

Answer:

lines EI and HG are parallel

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional

In this problem

If triangles EFI and GFH are similar

then

$\frac{EF}{FG}=\frac{FI}{FH}=\frac{EI}{GH}$

substitute the given values

$\frac{6}{3}=\frac{FI}{FH}=\frac{EI}{GH}$

$2=\frac{FI}{FH}=\frac{EI}{GH}$

If lines EI and HG are parallel

then the triangles are similar by AA Similarity Theorem

therefore

lines EI and HG are parallel
