1
Step-by-step explanation:
The cone is sliced by a plane, which produces a smaller cone on top. This cone is similar to the original cone. Therefore:
R / H = r / h
2 / 8 = r / 4
r = 1
Answer:
20/56 or 5/14
Step-by-step explanation:
Prob of red = 5/8
Second red prob = 4/7
multiply those = 20/56
simplify if needed = 5/14
Answer: The first one is x=4 and the second one is x=-1
Step-by-step explanation:
1.) add 5 to both sides then, subtract 2x to both sides then you get
5x=20. divide 5 to both side then you get x=4
2.) Subtract 4x to both sides then you add 8 to both sides then you get
x=-1.
Answer:
