Answer: A line with a slope of 2
Step-by-step explanation: the slope of the line is -1/2 so the negative reciprcal of the slope is 2 (It would be perpendicular to it)
i used m=y2-y2/x2-x1 to figure ou the slope and -(x/y) as the negative reciprcal for the perpendicular line.

Answer:
The area is given by:
And replacing we got:
So then we can conclude that the area of the coin is 
mm^2
Step-by-step explanation:
For this case we know that we have a coin with a diamter of 
, and by definition the radius is given by:
The area is given by:
And replacing we got:
So then we can conclude that the area of the coin is mm^2
Answer:
Step-by-step explanation:
95%+15%=110% so, 110%-100% is 10% and this means that 10% of both, costs 1.20. now, 10 times 1.20 is 12 dollars and we know that the whole purchace costs 12 dollars. 15 percent of 12 dollars is 1.8 dollars or, one dollar and 80 cents
100%=all
all-change of wining=change of not winning
100%-11%=89% of not winning
probabilit is 89/100 that they dont win
