Answer:
D. Open the compass so that the distance from the two points of the compass is wider than half the length of 
.
Step-by-step explanation:
To construct a perpendicular for , we must first take a compass & take the distance of its arms wider than half the length of .
This is done in order to get two intersecting arcs in the top & bottom of so that a perpendicular bisector can be drawn through it.
After two intersecting lines are drawn below & above , draw a line joining these 2 points through their points of intersection. The point where it intersects is the middle-most point of & now a perpendicular bisector of is constructed.
Answer:
44cm
Step-by-step explanation:
Formula for circumference, C = 2πr
where r is the radius
r = C / 2π
= 
=44 cm
The simple formula for velocity is v=d/t. Velocity equals distance divided by time. 360 miles divided by 180 minutes. 360/180=2. The car travels at 2 miles per MINUTE.
Now, to change to miles per HOUR. There are 60 minutes in an hour, so 2*60=120 miles per hour.
Answer: 120 mph
