Answer:
C
Step-by-step explanation:
The center of inscribed circle into triangle is point of intersection of all interior angles of triangle.
The center of circumscribed circle over triabgle is point of intersection of perpendicular bisectors to the sides.
Circumscribed circle always passes through the vertices of the triangle.
Inscribed circle is always tangent to the triangle's sides.
In your case angles' bisectors and perpendicular bisectors intesect at one point, so point A is the center of inscribed circle and the center of corcumsribed circle. Thus, these circles pass through the points X, Y, Z and G, E, F, respectively.
Get m by itself so divide each side by 6
m= 234/6
m=39
Cost depends on the class size , so
cost is the dependent variable and class size is the independent.
Answer:
Step-by-step explanation:
The collector has 160 movie posters and 120 band posters.
She wants to sell 24 movie posters but still have her poster collection maintain the same ratio of 160:120.
Total ratio = 160 + 120 = 280
If she sells 24 movie posters, it means
24 = 160/280 × x = 160x/280
Where x = total number of movie posters and band posters sold
24 × 280 = 160x
160x = 6720
x = 6720/160 =42
Number of band posters that she should sell = total number of both posters - number of movie posters.
Number of band posters that she should sell = 42-24 =18
