8:4. Basically, 8 people bought pineapple icecream, and 12-8 is 4, so there’s a remainder of 4 who bought chocolate icecream. Hope this helps! ^^
Neither, for lines to be parallel they have to have the same slope, and for lines to be perpendicular they have to be the negative reciprocal of the slope of the other line. In this case, the line perpendicular to the line with slope m=10 would be m=1/-10 or -1/10
The answer is 16 remadier 5
Scalene means uneven isosceles means two angles are even
