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.
Answer:
13 + 14 + 15
Step-by-step explanation:
n + (n + 1) + (n +2) =42
n + n + n + 1 + 2 = 42
3n + 3 = 42
(subtract 3 from both sides)
3n = 39
(divide both sides by 3)
n = 13
(solve)
n + (n + 1) + (n +2) =42
13 + (13 + 1) + (13 + 2) = 42
13 + (14) + (15) = 42
13, 14, 15
(Hope this helps, have a nice day!)
