While traveling to Europe, Phelan exchanged 250 US dollars for euros. He spent 150 euros on his trip. After returning to the United States he converts his money back to US dollars. How much of the original 250 US dollars does Phelan now have? Round to the nearest cent. 1 European euro = 1.3687 US dollars

44.70 US dollars
73.06 US dollars
136.87 US dollars
140.41 US dollars

140.41 USD

Step-by-step explanation:

$44.70

Step-by-step explanation:

1 euro = $1.3687

First, we convert $250 to euros.

$250 * (1 euro)/($1.3687) = 182.66 euros

He started with $250 which is the same as 182.66 euros.

He spent 150 euros.

182.66 euros - 150 euros = 32.66 euros

He had 32.66 euros left. Now we convert 32.66 euros to dollars.

32.66 euros * ($1.3687)/(1 euro) = $44.70

$44.70

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
