4 full jars is 4 x 3.5 liters
then add the 1/2 full one 1/2 X 3.5
Take each line and multiply it and sum them 0 *3 + 1*9 + 2*10 etc
then divide by the total of the second column 3 + 9 + 10 ......
YOU are not passing a test if someone else is answering the questions !
Slope, m of the given line is - 3/4 perpindicular is - 1/m = 4/3
the answer is one of the choices with 4/3 in it .....
sub in the point (6,-2) into the choices to see which one is true

Area of a quarter circle of radius 12 = 1/4 pi 12^2
subtract the triangle area: 1/2 b h = 1/2 12 x 12
perimeter = hypotenuse of right triangle with legs = 12 and 12 sqrt (122 + 122 )
+ 1/4 pi x d d = diameter = 24

Q 1019 answer is B
Q 17370 Area is: NOT (a U b) Not sure of the notation used .....is that ( A U B)' ???
tan 30 = 1/sqrt3 = a/AD
AD = sqrt 3 *a
tan45 = 1 = a/DB
DB = a
AD + DB = AB = sqrt3 * a + a = (1+ sqrt 3) a
