An archaeological artifact is depicting figures of some natural and artificial objects like the sun, moon, comet, star, flower, horse, bird , insect, headdress, mountains, river, house, weapons, bonfire and necklace. The translation of the symbol message below is "WIND, RAIN, FLAME, SOIL, ESSENCE". According to experts, there are 5 polyomino tiles that were used as patterns for making the outline of the figures in this artwork. They also believed that these 5 tiles altogether should fill and fit in any of the 16 figures depicted above. What are these polyominoes?

The artist in the market is giving this painting for free (the last one on his rack). I asked him if I can take it but he replied "Why should I give it to you?" The frame could be useful but I don't want to tell him that so I ask him why should he give it for free. He answered "because I miss to paint something into it". It looks like straight edge drawing to me but Im curious so I asked him what is missing in his painting. He told me that I can take it if I figured it out. I offer to buy it if he would tell me but he just refused while people are now gathering around the painting. What is missing?

nice but not the most that he can earn

Bill has five pennies . He shall make as many triangles as he can to gain more money. For every unique triangle that he creates on a flat table (3 corners at centers of coins) he wins a nickle but for some triangles that dont overlap or intersect with other triangles, he wins a dime. He shall declare the triangles he formed on the table. So Bill can name the identical coins A,B,C,D and E. Note U$ penny is 1-cent, nickle is 5-cents and dime is 10-cents. How shall Bill put all his coins on the table for greatest earnings?
