Solution:

38

Explanation:
The total number of triangles are 8.

Let us divide the triangles in three categories: small, medium and large.

If we start with the small triangles, you can count a total of 24 triangles. 12 triangles (3 + 4 + 3 + 2) are upward facing and 12 are downward facing.

Next, we count the medium sized triangles. You can find a total of 12 triangles. 6 triangles (3 + 2 + 1) are facing upwards and 6 are facing downwards.

Lastly, if you calculate the large triangles, they are only two. One is upward facing and one is facing downward.

24 + 12 + 2 = 38.

Solution:

He should shoot at the ground.

If Kangwa shoots the ground, it is Rafael's turn. Rafael would rather shoot at Ferdinand than Kangwa, because he is better.
If Rafael kills Ferdinand, it is just Kangwa and Rafael left, giving Kangwa a fair chance of winning.
If Rafael does not kill Ferdinand, it is Ferdinand's turn. He would rather shoot at Rafael and will definitely kill him. Even though it is now Kangwa against Ferdinand, Kangwa has a better chance of winning than before.

Solution:

Q = 1
U = 9
I = 6
C = 8
K = 3.

Explanation:
Replace values in( Q + U + I + C + K)^3 = QUICK
(1+9+8+6+3)^3 = 19863
27^3 = 19863
19863 = 19863

Solution:

If you see the picture, they formed a pentagonal shape and achieved the required.

Solution:

Fifteen minutes can easily be measure using these two hour glasses.

Step 1: He will start both the hourglass.

Step 2: The moment the eleven minute hourglass is empty, he will invert it.

Step 3: When the thirteen minutes hourglass is empty, he will invert the eleven minute hourglass.
In step 3, we will have counted thirteen minutes. Since we inverted the eleven minute hourglass in step 2, it started from fresh and was inverted just for two minutes (13-11=2). In this manner when it is reversed when the thirteen minute hourglass is finished, it will have two minutes of sand left. This time when the sand finishes, he will have measured fifteen minutes. (13+2=15)
