Line 1 and line 4 are parallel
Step-by-step explanation:
Two lines are said to be parallel if they have same slope.
In order to compare the lines given, we have to write them all in the same form, and then compare their slopes.
Line 1:
Applying distributive property,
Line 2:
Line 3:
Applying distributive property,
Line 4:
re-arranging,
Now we have rewritten all the lines in the form , where m is the slope. By comparing the values of m, we see:
Therefore, the lines which are parallel are line 1 and line 4.

Answer:
B
Step-by-step explanation:
<em>Let be the radius of one sphere.</em>
- Volume of sphere is
Since radius is r, the height of the cylinder will be
Also, the cylinder has the same radius as the sphere:
- Volume of Cylinder is
Plugging in the values we get:
<u>Ratio of volume of 1 sphere to volume of cylinder is</u>:
The ratio is 1:3
Answer choice B is right.
