Answer:
they can each sit on floor by lining equally some can move back for example the shortest ones can sit medium tall can stand and the largest people can stand in the very back
620*1.35=837 so 837ml is the answer
Given:
• AD = 3
,
• DC = 27
,
• BD = x + 3
Let's solve for x.
To solve for x, apply the altitude formula:
![\frac{AD}{BD}=\frac{BD}{DC}](https://tex.z-dn.net/?f=%5Cfrac%7BAD%7D%7BBD%7D%3D%5Cfrac%7BBD%7D%7BDC%7D)
Where BD is the altitude.
Cross multiply:
![BD^2=AD*DC](https://tex.z-dn.net/?f=BD%5E2%3DAD%2ADC)
Plug in the values and solve for x:
![\begin{gathered} (x+3)^2=3*27 \\ \\ (x+3)^2=81 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%28x%2B3%29%5E2%3D3%2A27%20%5C%5C%20%20%5C%5C%20%28x%2B3%29%5E2%3D81%20%5Cend%7Bgathered%7D)
Take the square root of both sides:
![\begin{gathered} \sqrt{(x+3)^2}=\sqrt{81} \\ \\ x+3=9 \\ \\ \text{ Subtract 3 from both sides:} \\ x+3-3=9-3 \\ \\ x=6 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Csqrt%7B%28x%2B3%29%5E2%7D%3D%5Csqrt%7B81%7D%20%5C%5C%20%20%5C%5C%20x%2B3%3D9%20%5C%5C%20%20%5C%5C%20%5Ctext%7B%20Subtract%203%20from%20both%20sides%3A%7D%20%5C%5C%20x%2B3-3%3D9-3%20%5C%5C%20%20%5C%5C%20x%3D6%20%5Cend%7Bgathered%7D)
Therefore, the value of x is 6 .
