In Euclidean planar geometry, not unless they're collinear, in which case they intersect an infinite number of times.
In other types of geometry ... maybe.

How many times can 2 circles with different diameters intersect?
Twice max.
The angle of rotation is the measure of the angle formed by the lines?
the answer is twice. the angle of rotation is twice the measure
Does to intersect each other mean also to bisect each other?
No. If two lines intersect they cross each other. To bisect each other, means that the lines not only intersect but that also that the point where the two line[ segment]s cross is the mid point of both of the line[ segment]s. Examples, consider: The diagonals of a kite ABCD with sides AB & AD equal (2 cm each), and BC & DC equal and twice the length of the other two sides (4 cm each). The diagonals AC and BD intersect each other; BD is bisected by AC but AC is NOT bisected by BD. The diagonals of a right angle trapezium ABCD with ∠DAB and ∠ADC right angles (so sides AB and DC are parallel) and with sides AB = 2 cm, CD = 14 cm and AD = 5 cm (side BC = 13 cm). The diagonals AC and BD intersect, but NEITHER bisects the other. The diagonals AC and BD of a square ABCD not only intersect each other, but they also do, in this case, bisect each other.
How can you add 5 lines to 4 lines to get 10 without counting any line that intersects another line twice?
the four lines you are adding five line to are vertical.
Why do two magnetic lines never intersect each other?
It is important to realize that magnetic lines do not really exist! They are a tool to visualize the magnetic field, but the field is continuous and does not exist solely inside lines. The direction of the lines gives the direction of the magnetic field, the density of lines, its strength. This also explains why no two field lines can ever intersect; a field line carries information about the direction of the magnetic field, if they would intersect an ambiguity would arise about the direction (not to mention a field of apparent infinite strength since the density would be infinite at the point of crossing). The field lines are almost never used in explicit calculations; instead one uses a vector, an entity which contains information about the magnitude and direction of a field in every point in space and time. Adding two magnetic fields is then easy; just add the vectors of both fields in every point in space (and time). You can use the resulting vector field to draw field lines again if you want. An easy way to imagine what would happen to field lines when they might intersect is to look at them as being such vectors. Imagine you have one field line pointing to the right, and another one pointing up. The result of adding would be a field line pointing somewhere in the up-right direction (the exact direction depending on the relative magnitudes of the fields). If the fields are equal in magnitude but opposite in direction they would cancel; the field line disappears. But this is to be expected! The magnetic fields canceled each other in that point! One has to take care with this analogy however; as for field lines the measure of magnitude is their density; which is an undefined thing if you are considering just one field line per field. For a vector however, the measure of magnitude is its length. Therefore adding two field lines of the same magnitude and pointing in the same direction would result in a vector of twice the length, but in field line language you would have to double the density at that point. This is one of the reasons field lines are used for visualization but not calculation. By the way, all these things apply to other fields as well. Electric fields can also be represented by field lines, and they as well cannot intersect (for the same reasons). Electric field lines, however, are not necessarily closed loops like magnetic field lines (this has to do with the non-existence of magnetic monopoles).
What is the maximum number of distinct intersections of 30 different coplanar circles?
No two circles can intersect more than twice. Each circle can intersect with each other circle. Thus there ought to be 2 × 30 × (30 - 1) intersections. However, this counts each intersection twice: once for each circle. Thus the answer is half this, giving: maximum_number_of_intersections = ½ × 2 × 30 × (30 - 1) = 30 × 29 = 870.
Does a tangent intersect a circle twice?
no. you have to draw it such that it doesn't.
How do you find the venn diagram for union of three sets?
Draw your Venn Diagram as three overlapping circles. Each circle is a set. The union of the sets is what's contained within all 3 circles, making sure not to count the overlapping portion twice. An easier problem is when you have 2 sets, lets say A and B. In a Venn Diagram that looks like 2 overlapping circles. A union B = A + B - (A intersect B) A intersect B is the region that both circles have in common. You subtract that because it has already been included when you added circle A, so you don't want to add that Again with circle B, thus you subtract after adding B. With three sets, A, B, C A union B union C = A + B - (A intersect B) + C - (A intersect C) - (B intersect C) + (A intersect B intersect C) You have to add the middle region (A intersect B intersect C) back because when you subtract A intersect C and B intersect C you are actually subtracting the very middle region Twice, and that's not accurate. This would be easier to explain if we could actually draw circles.
How many times can 2 circles with different diameters intersect?
Twice max.
Design a combinational circuit that accepts a three bit number and generates a binary output equal to twice the input value?
There is no need for a combinatorial circuit to multiply a number by two. A binary number, left shifted one place, is twice the original binary number. The specific answer to the question is that you would connect the three input lines to the three high order output line of four output lines, and connect the low order bit of the four output lines to logic 0. If the three input lines were labelled A, B, and C, the output would be A, B, C, and 0.
The angle of rotation is the measure of the angle formed by the lines?
the answer is twice. the angle of rotation is twice the measure
What is the quotient of twice a number and five?
What is the quotient of twice the number and three

How many people would get a slice of pizza if you cut it twice once vertically and once horizonally?
Cutting any convex polygon twice in such a way that the cuts intersect inside the polygon will divide it into four (not necessarily equal) pieces.
What is the Point of concurrency of the medians of a triangle?
The point of concurrency of the medians of a triangle is called the centroid. It is the point where all three medians intersect each other. The centroid divides each median into two segments, with the segment closer to the vertex being twice as long as the other segment.
Which type of line that tests for a function?
Vertical line. If you can draw a vertical line through some part of a graph and it will intersect with the graph twice, the graph isn't a function.
How can you add 5 lines to 4 lines to get 10 without counting any line that intersects another line twice?
the four lines you are adding five line to are vertical.
