The correct answer is C) 12
Euler's formula states that the number of vertices subtracted by the number of edges and added to the number of faces of a polyhedron always equals 2:
V - E + F = 2
We have 24 edges and 14 faces:
V - 24 + 14 = 2
Combining like terms,
V - 10 = 2
Add 10 to both sides:
V - 10 + 10 = 2 + 10
V = 12

Answer:2 ft
Step-by-step explanation:
Area of circle = pi x r^2 = 4 pi
So r^2 = 4
r =2
Answer:
yes
Step-by-step explanation:
Ratios are equivalent if they are multiples or divisors of each other.
5 : 2 ( multiply both sides by 6 )
= 30 : 12
or
30 : 12 ( divide both sides by 6 )
= 5 : 2
Thus 5 : 2 and 30 : 12 are equivalent ratios
1 year has 365.25 days in it (that's why we add a leap day every 4 years)
1day=24hours
1hour=60mins
1min=60secs
365.25*24*60*60=31557600 seconds in a year
2.05*10^5=205000 seconds
205000/31557600=0.0064905800187593479859051385403 years
