Answer:
what the choices?
Step-by-step explanation:
The radius is half of the diameter.
To find the circumference, use the equation C=2(pi)r or C=(pi)d.
r meaning radius. d meaning diameter.
(pi) is about 3.14 or 22/7
A1 = 0.91
a6 = -0.14
sum = (0.91+-0.14) /2
sum = 2.31
Answer:
14. A. Commutative Property of Addition.
15. D. k=54
Step-by-step explanation:
6 + 9 = 9 + 6 is an example of the Commutative Property of Addition so that is your answer.
k + (-12) = 42. What you do is add the 12 to both sides to get your answer.
k=54 is your answer.
Answer:
Step-by-step explanation:
if (x,y) is the centroid. Then x=(x1+x2+x3)/3,y=(y1+y2+y3)/3
5.
x=(-2+4+10)/3=4
y=(6+0+6)/3=4
centroid=(4,4)
6.
x=(3+5-2)/3=2
y=(3-1+1)/3=1
centroid=(2,1)
