Rly, this is the stupidest question to live on earth
Y<span>ou </span>can<span> describe </span>lines<span>, rays, and </span>line segments<span> by the way they meet or cross each other. Words </span>Parallel lines<span> are always the same distance apart. They do not meet. Words </span>Lines<span> that meet or cross each other are called intersecting </span>lines<span>.

Answer:
Step-by-step explanation:
Bob ran the first part of a 12 km race at a speed of 8 kmph. He ran the second part of the
race at 10 kmph. If his total time for the entire race was 1.74 hours, how far did he run in
the first part of the race?
First part :
Total Distance = 12 km
First part Speed = 8kmph
Let distance covered on first part = x
Second part speed = 10kmhr
(8*x)

Answer: 6</h3>
===========================================================
Explanation:
Rule: If a set has n elements in it, then it will have 2^n subsets.
For example, there are n = 3 elements in the set {a,b,c}. This means there are 2^n = 2^3 = 8 subsets. The eight subsets are listed below.
- {a,b,c} .... any set is a subset of itself
- {a,b}
- {a,c}
- {b,c}
- {a}
- {b}
- {c}
- { } ..... the empty set
Subsets 2 through 4 are subsets with exactly 2 elements. Subsets 5 through 7 are singletons (aka sets with 1 element). The last subset is the empty set which is a subset of any set. You could use the special symbol
to indicate the empty set.

-------------------
The problem is asking what value of n will make 2^n = 64 true.
You could guess-and-check your way to see that 2^n = 64 has the solution n = 6.
Another approach is to follow these steps.

Which is fairly trivial.
Or you can use logarithms to solve for the exponent.

Due to rounding error, we don't land exactly on 6 even though we should.
