Answer: 2.815 kilograms
======================================================
Work Shown:
1 layer = 0.5 kg
5 layers = 5*(0.5 kg) = 2.5 kg
icing = 15 g = 15/1000 = 0.015 kg
1 candle = 100 g = 100/1000 = 0.1 kg
3 candles = 3*(0.1 kg) = 0.3 kg
------------------------
The five layers combine to 2.5 kg. On top of that we have 0.015 kg of icing, and then finally the three candles add 0.3 kg more weight.
The total weight is therefore: 2.5+0.015+0.3 = 2.815 kilograms

Answer:
Yes, he will have enough 3 over 8 ft pieces for his class.
Step-by-step explanation:
Given:
Number of wood required = 22
Length of each wood, ![l=\frac{3}{8}\textrm{ ft}](https://tex.z-dn.net/?f=l%3D%5Cfrac%7B3%7D%7B8%7D%5Ctextrm%7B%20ft%7D)
Total length of the board, ![L=9\textrm{ ft}](https://tex.z-dn.net/?f=L%3D9%5Ctextrm%7B%20ft%7D)
Therefore, the number of woods that can be made using the given board is given as:
![\textrm{Number of woods made}=\frac{\textrm{Total length of board}}{\textrm{Length of each wood}}\\\textrm{Number of woods made}=\frac{L}{l}=\frac{9}{\frac{3}{8}}=9\times \frac{8}{3}=\frac{72}{3}=24](https://tex.z-dn.net/?f=%5Ctextrm%7BNumber%20of%20woods%20made%7D%3D%5Cfrac%7B%5Ctextrm%7BTotal%20length%20of%20board%7D%7D%7B%5Ctextrm%7BLength%20of%20each%20wood%7D%7D%5C%5C%5Ctextrm%7BNumber%20of%20woods%20made%7D%3D%5Cfrac%7BL%7D%7Bl%7D%3D%5Cfrac%7B9%7D%7B%5Cfrac%7B3%7D%7B8%7D%7D%3D9%5Ctimes%20%5Cfrac%7B8%7D%7B3%7D%3D%5Cfrac%7B72%7D%7B3%7D%3D24)
So, he can make 24 woods of length
using the 9 ft board. But he has to make only 22 pieces.
Therefore, he has enough of the wood to make the required number of pieces.
If a line <span>parallel </span>to one side of a <span>triangle </span>intersects the other two sides of the triangle, then the line divides these two sides proportionally.
