Drag each scenario to show whether the final result will be greater than the original value, less than the original value, or the same as the original value.

same as original.

less than original.

less than original.

same as original.

greater than original

Step-by-step explanation:

Let the original amount be $100.

A)  50% decrease = 100-50%of 100=100-50=$50

Then increase 100 % = 50+100% of 50=50+50=$100, which is same as original.

B) 20% increase = 100+20%of 100=100+20=$120

Then decrease 25 % = 120-25% of 120=120-30=$90, which is less than original.

C) $25 increase = 100+25=$125

Then decrease $30= 125-30=$95, which is less than original.

D)  

decrease =

Then increase 50%=, which is same as original.

E) 80% increase = 100+80%of 100=100+80=$180

Then decrease 40% = 180-40% of 180=180-72=$102, which is greater than original.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
