The answer is A) Round 56 to 60, find 10%, then double.
Step-by-step explanation:
You would round to 60 because 56 is closer to 60 than 50 then 10% is half of 20% so you would double it after you found 10% of 60.

Answer:
The point of intersection is (0,-2).
Step-by-step explanation:
Equation 1: 
Equation 2 : 
Plot the lines on the graph
Refer the attached figure
Equation 1: 
Equation 2 : 
Point of intersection : A point where both the lines intersect is called point of intersection.
So, Both lines intersect at point (0,-2)
So, Point of intersection is (0,-2)
Hence The point of intersection is (0,-2).
The square root of 110 is 10.49. Hope this helps you!
Firstly triangle OAB is equilateral so R = AB =OA = 8 in
MES (ARC AB) = R x Ф (in Radian). Note that 60° =π/3
MES (ARC AB) = 8 x π/3 (D)
