A postulate is an assumption we use for mathematical reasoning; it isn't yet proven. once it's proven, it becomes a theorem.
Answer:
286.97
Step-by-step explanation:
find the area of the rectangle first
14*15=210
Next
Find the area of a circle
πr^2=a
the radius of the circle is half the height of the rectangle
π*(7*7)=a
a=153.94
Now
Divide the area by two
153.94/2=76.97
Now add the two areas
76.97+210
(-3,4)(0,-3)
slope = (-3 - 4) / (0 - (-3) = -7/3 <=
N= P-180. so the computer would originally be 720 dollars. reduced by 25%, or 180, the new price is 540.
