Answer:
Step-by-step explanation:
d=4 miles=4×1760 yards=7040 yards=7040×3 ft
number of lights=21120 ft
number of lights=21120/145 +1≈145.7+1=146+1=147 lights
THis is a cool question.
1) Use the point slope form to find the equation of the lines between two of the points (choose two points that when a line is drawn between them make a chord on the circle).
2) Use the midpoint of a line equation to find the midpoint of the line, then find the slope of the line that is perpendicular at that point and write an equation for it.
3) Then do the same thing for the other two points that form a chord on the circle.
4) Then set the two equations equal to each other and solve. The point where they meet is the circumcenter.
Answer:
0.5 or 3/6 min
Step-by-step explanation:
so
1/3= 1/6min or 10 sec
to finish the whole apple 3/3 is required
1 part is 10 sec, 3 parts will be 30 secs which is 0.5 /3/6 min.
hope this helps
