It would be 15-5=10 that is because you subtract q3-q1
I think its B cause it make more sence to analyze the two groups and calculate the diffrence
In my opinion I think that you have to multiply 13.55 by 8 ounces to find how much she needs to pay.
Answer:
c
Step-by-step explanation:
Pi/3 is equivalent to 60 degrees, as 2pi is equal to 360 degrees. cos(60) in a triangle yields 1/2, and sin(60) yields (3^(1/2))/2. Thus, -pi/3, or -60 degrees would be a fourth quadrant point on the unit circle and these values would be negative as well, at cos(-pi/3)=-1/2 and sin(-pi/3)=-(3^(1/2))/2
