Four takes 10 minutes. 
166/4=41.5
There are 41.5 fours in 166
Each four takes 10 minutes
41.5 fours takes 41.5*10=415 minutes

Answer:
centre = (4,-2) 
radius = 3
Step-by-step explanation:
The centre-radius form of the circle equation is in the format
 (x – h)² + (y – k)² = r², 
with the centre being at the point (h, k) and the radius being "r"
Given in the question an expression which can be write as
<h3> (x – 4)² + (y – (-2))² = 3²</h3>
So, by translating we can say that
centre = (4,-2) 
and
radius = 3
  
 
        
             
        
        
        
Answer:
x = 7
Step-by-step explanation:
The proportion is
14/6 = 21/(3x - 12)                 Cross Multiply
14*(3x - 12) = 6*21                 Remove the brackets and combine
42x - 168 = 126                     Add 168 to both sides
42x = 126 + 168
42x =  294                           Divide by 42
x = 294/42
x = 7
