Answer:
D
Step-by-step explanation:
30.20 * 15% (or 0.15) = 4.53
4.53 is about 4.50
Answer: 98
Step-by-step explanation:
-1.5 + 7.5
factor out -1.5, divide 7.5 by 1.5 to factor it out of it as well (7.5 divided by -1.5) and make sure you get NEGATIVE 5.
-1.5(1 x -5)
In a circle, the number of radians is proportional to the relative length of the arc, in comparison to the radius. We have that if we denote by x the radians, the following proportionality holds, relating angles and lengths:

because the total of angles in radians is 2pi and the total circumference is 2pi times the radius. Hence, by solving for x we get: x=4/7=0.57 rad
We also have that the area is proportional to the angles. The total are is

. Hence, A=
