Answer:
,
Step-by-step explanation:
we know that
In a parallelogram, opposite angles are congruent and consecutive angles are supplementary
so
----> equation A
-----> equation B
we have

substitute in the equation B and solve for m<R


-----> substitute in equation A
The equation for the area of a circle is:
A=π*radius squared.
Since radius is half of the diameter.
Diameter/2=radius
Then plug it into the equation.
Answer: The same trip will require 3.8 hours.
Step-by-step explanation:
Since we have given that
Time = 
Speed = 55 mph
So, distance would be

If the speed limit = 65 mph
So, time will be

Hence, the same trip will require 3.8 hours.
Answer:
3
Step-by-step explanation:
If figure A is half the size of figure B, then 1.5 x 2 = 3.
