Answer: z=1/2
Step-by-step explanation:
12z-6=-8z+4
20z=10
z=1/2
This is an area problem where the area of a circle is pi*r^2.
A quiche with a diameter of 12 has an area of pi*6^2 = 36pi
So if it can feed 6 people, then the serving size per person is 6pi per person.
A quiche with a diameter of 10 inches has an area of pi*5^2 = 25pi
If each person requires 6pi worth of quiche, then 25pi/6pi = 4 1/6 people.
So yes, it can serve 4 people.

Answer:
66.56cm = perimeter
Step-by-step explanation:
First find the easy part (the rectangle)
10+10+17+17=54
subtract the part that is not really there (dashes)
54-8=46
Add the height of the circular part
46+8=54
Find the circumference of a circle with a radius of 8
2(8)(3.14)=50.24
Divide by 4 (the circumference is only 1/4 of the the actual circle in this problem)
50.24/4=12.56
Add all of it together
12.56+54=66.56
