Answer:

25.047 or roughly 25.

Step-by-step explanation:

I solved it wrong the first time then i double check with wolframalpha and got the correct number.

We know that the area of the tile is 18 \sqrt{3} and it makes a triangle, we also know the base and height. In this case the base is 2\sqrt{3}^{x/12} and the height is also given which is \sqrt{3}^{\frac{x}{6} }.

Area of triangle = \frac{bh}{2},

substituting we will end up with  18 \sqrt{3}  =( 2\sqrt{3}^{x/12}  *  \sqrt{3}^{\frac{x}{6} }) / 2

Here is the tricky part \sqrt{x} = x^{\frac{1}{2} }, i totally forgot about that lol.

Simplifying: we will get  18 \sqrt{3} = 3^{\frac{x}{8} }

Now, in order to find the x, we will need to take the log of both sides.

log18\sqrt{3}  = \frac{x}{8} log3

Solving for x we end up getting:

8\frac{log18\sqrt{3} }{log3} = x

where x = 25.047.

To be honest I deserve a nobel prize not a brainliest lol.

Good question bro, take it easy.

William had a board that was 5 ft. 3 in. long. He cut off a piece that was 2 ft. 8 in. long. How much board does he have left
Mrac [35]

All you have to do here is convert the mixed number measurements to inches. Because there are 12 inches in a foot, 5ft. 3in. becomes 63 inches. 2ft. 8in. becomes 32 inches. 63-32=31 inches, which is 2ft. 7in.

A patient is on a low​ sodium, low fat diet. Three months ago the patient weighed 240 1/8 lb Now the patient weighs 215 5/8lb Ho
grin007 [14]

namely what's 240⅛ - 215⅝.


firstly, let's convert the mixed fractions to improper, and then divide.


\bf \stackrel{mixed}{240\frac{1}{8}}\implies \cfrac{240\cdot 8+1}{8}\implies \stackrel{improper}{\cfrac{1921}{8}} \\\\\\ \stackrel{mixed}{215\frac{5}{8}}\implies \cfrac{215\cdot 8+5}{8}\implies \stackrel{improper}{\cfrac{1725}{8}} \\\\\\ \cfrac{1921}{8}-\cfrac{1725}{8}\implies \stackrel{\textit{LCD is clearly 8}}{\cfrac{1921-1725}{8}}\implies \cfrac{196}{8}\implies \cfrac{49}{2}\implies 24\frac{1}{2}
