Answer: 2/15
Step-by-step explanation: What you have to do is add what they ate then subtract it from the entire pizza to get how much remains. so 2/3 + 1/5 =13/15
15/15 (the whole pizza which equals 1) -13/15= 2/15
step 1
Find the radius of the circle
To find out the radius, calculate the distance between the center and any point that lie on the circle
so
(-2,3) and (-2,0)
Its a vertical distance
so
r=3-0=3 units
step 2
we have the radius r=3 units and the center (-2,3)
the equation of the circle is

We find out the ratio 100: 12= 25/3
We need the number of <span>sticks of butter: 25/3 x 3/2= 25/2=12.5
That means you must buy 13 </span><span>sticks of butter
Have fun</span>
