Answer:
7/20
Step-by-step explanation:
![\frac{11}{20}+x=\frac{9}{10} \\x=\frac{7}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B20%7D%2Bx%3D%5Cfrac%7B9%7D%7B10%7D%20%5C%5Cx%3D%5Cfrac%7B7%7D%7B20%7D)
Answer:
4√10xy/32y is the answer. (I think)
![\bf \textit{volume of a pyramid}\\\\ V=\cfrac{1}{3}Bh\qquad \begin{cases} B=\textit{area of the base}\\ h=height \end{cases}](https://tex.z-dn.net/?f=%5Cbf%20%5Ctextit%7Bvolume%20of%20a%20pyramid%7D%5C%5C%5C%5C%0AV%3D%5Ccfrac%7B1%7D%7B3%7DBh%5Cqquad%20%0A%5Cbegin%7Bcases%7D%0AB%3D%5Ctextit%7Barea%20of%20the%20base%7D%5C%5C%0Ah%3Dheight%0A%5Cend%7Bcases%7D)
now, the first one, on the far-left.... can't see the height.. but I gather you do, now as far as its Base area, well, the bottom is just a 12x12 square, so the area of its base is just 12*12
now, the middle pyramid, has a height of 6, the base is also a square, 8x8, so the Base area is just 8*8
now the last one on the far-right
has a height of 8, the Base is a Hexagon, with sides of 6
Two figures that have the same shape are said to be similar. When two figures are similar, the ratios of the lengths of their corresponding sides are equal. To determine if the triangles below are similar, compare their corresponding sides.
