Why is it so complicated? Volume of one cube is 1/2 * 1/2 * 1/2 = 1/8 cm^3
Volume of prism is 1/8 * 96 = 12 cm^3
Answer:
2 : 3
Step-by-step explanation:
4 : 6
Divide each by 2
2 : 3
Answer:18
Step-by-step explanation:
Sin72=cosy
0.9511=cosy
Y=cos(inverse)0.9511
Y=18
Graph a.
3x+2y=12
-3x -3x
2y=-3x+12
2/2y=(3x+12)/2
y=-1.5x+6
graph b.
4x-y=5
+y +y
4x=y+5
-5 -5
4x-5=y
c) 11 units is the difference between y-coordinates of graph a and y-coordinates of graph b.
e) at (6,-3) x=6 cuts into graph a
Answer:
part a is about 55%
part b I'm not too sure about, but it might be 60%
part c I have no idea, sorry
