Garden one has 9 more bushes of red currant than garden two. If 3 bushes were transplanted from garden two to garden one, then g
Vesnalui [34]

Garden one and two are both unknown, so I am choosing to call garden 2 X and then label garden 1 with comparisons to X.

It is tempting to list:

Garden Two = X

Garden One = X + 9

BUT there is an easier way. We are told that when 3 bushes are taken from garden 2 (x-3) and put in garden 1 (x + 12) then garden one has 1.5 times more than garden two.

Set it up like this:

1.5 ( x - 3) = x + 12 (because 1.5 times garden 2 will give us garden 1)

1.5x - 4.5 = x + 12 (Distribute)

.5x = 16.5 (Use subtraction to move variables to the right and other numb left)

x = 33 for Garden 2

33  + 9 for Garden 1 = 42

The angle θ lies in Quadrant II .
Andreyy89

let's keep in mind that, in the II Quadrant, cosine is negative and sine, is positive.

cosine is adjacent/hypotenuse, however the hypotenuse is simply a radius unit, and thus is never negative, so in the -(2/3) the negative must be the numerator, -2.


\bf cos(\theta )=\cfrac{\stackrel{adjacent}{-2}}{\stackrel{hypotenuse}{3}}\impliedby \textit{let's find the \underline{opposite side}} \\\\\\ \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies \sqrt{c^2-a^2}=b \qquad \begin{cases} c=hypotenuse\\ a=adjacent\\ b=opposite\\ \end{cases} \\\\\\ \pm\sqrt{3^2-(-2)^2}=b\implies \pm\sqrt{5}=b\implies \stackrel{\textit{II Quadrant}}{+\sqrt{5}=b}~\hfill tan(\theta )=\cfrac{\stackrel{opposite}{\sqrt{5}}}{\stackrel{adjacent}{-2}} \\\\\\ ~\hspace{34em}
