Answer:The distance from a point to a line is
distance(ax+by+c=0,(x0,y0)) = abs(ax0+by0+c)/sqrt(a^2+b^2)
So first convert the formula for the line to standard form
5x+2y=4
5x+2y-4=0
a=5, b=2, c=-4, x0=15, y0=-21
Step-by-step explanation:
Well
if it is marked 1/3 off, then you're actually paying 2/3 of it.
2/3 of 123. " of " means multiply
2/3 * 123 = 246/3 = 82 So it now costs $ 82
Answer:
$189
Step-by-step explanation:
35% of 140 = 49
140 + 149 = 189
8 times 2 is 16 and 12 times 3 is 36. So 16 plus 36 is 52
Answer:
Please look at the attachment for the figure of circle with radius, diameter,circumference labelled.
AB is the diameter
OB and OA are radii
Radius is half of the diameter or in other words diameter is double of radius.
And circumference is the outer line of the circle
