A flat three dimensional solid like a cube, a prism or a pyramid. When you cut out the "net", fold it and glue it together you can see what the three dimensional shape looks like. (It can be used in math)Draw a net of the polyhedron. Calculate the area of each face. Add up the area of all the faces.
if we take 31 to be the 100%, what is 28 off of it in percentage?
![\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 31&100\\ 28&x \end{array}\implies \cfrac{31}{28}=\cfrac{100}{x}\implies 31x=2800\implies x=\cfrac{2800}{31} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill x\approx 90.32~\hfill](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccll%7D%20amount%26%5C%25%5C%5C%20%5Ccline%7B1-2%7D%2031%26100%5C%5C%2028%26x%20%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B31%7D%7B28%7D%3D%5Ccfrac%7B100%7D%7Bx%7D%5Cimplies%2031x%3D2800%5Cimplies%20x%3D%5Ccfrac%7B2800%7D%7B31%7D%20%5C%5C%5C%5C%5B-0.35em%5D%20%5Crule%7B34em%7D%7B0.25pt%7D%5C%5C%5C%5C%20~%5Chfill%20x%5Capprox%2090.32~%5Chfill)
40% of 740 is 444, and 30% of 444 is 133.2 ,so the answer is $133.2
Answer:
Step-by-step explanation:
each box has 12 melon for 15 dollars:
the price of one melon : 15/12=1.25 dollar each
he bought 12 boxes of melon and paid 15 dollars for each :
12*15=180 dollars
total melon is : 12*12=144 dollars
he sold 3/4 of a melon : 3/4 *144=108
the cost of 108 : 108*1.25= 135 dollars
at a price of $ 1.6 = 108*1.6= 172.8
the rest of the melon sold at reduce price=
144-108= 36
over all profit = 15 %
180*(1+0.15)=207 dollars profit
selling 108 melons : $172.8
overall profit - profit from selling 108 melons: 207-172.8=$34.2
<h2>reduced price = 34.2/36=0.95 dollars</h2>
