Radius is 142
You must find the diameter
Want to find diameter you need to take the number of radius is 142 Multiply 2
= 284
The circumference is 284
Vertices are formed when 2 sides come together on a polygon. So they are basically corners. The smallest amount of sides a polygon has is 3, which would be a triangle. And triangles have 3 corners, because with a triangle, each side touches the other two. So the minimum number of vertices needed to form a polygon would be 3.
Answer:
grax
Step-by-step explanation:
...
X = number of adult tickets
7x = value of the adult tickets
3x = number of child tickets
3x * 3 = value of children's tickets, which is also 9x
Value of adults plus value of children's = 6000
7x + 9x = 6000
Combine terms
16x = 6000
Divide by 16
x = 6000/16
Simplify fraction
x = 3000/8 = 1500/4 = 750/2 = 375 = number of adult tickets
Number of children's tickets = 3 * 375 = 1125 = number of children's tickets
Check:
Adults = 375 * 7 = 2625
Children's = 1125 * 3 = 3375
Total = 6000
