Step-by-step explanation:

Given : Stephanie has a fish tank with 10 adult fish and 45 baby fish.

To find : What is the ratio of adult fish to baby fish in the tank?

Solution :

Number of adult fish in the tank is 10.

Number of baby fish in the tank is 45.

The ratio of adult fish to baby fish in the tank is given by,

Number of adult fish : Number of baby fish

10 : 45

Converting 10 : 45 into simpler form is

$10 : 45 =2\times 5: 9\times 5=2 : 9$

Therefore, The ratio of adult fish to baby fish in the tank is 2:9.

Solve the equation on the<br> interval [0, 27r).<br> 4(sin x)2 - 2 = 0

Ket [755]

$4[sin(x)]^2 - 2 = 0\implies 4[sin(x)]^2=2\implies [sin(x)]^2=\cfrac{2}{4}\implies [sin(x)]^2=\cfrac{1}{2} \\\\\\ sin(x)=\pm\sqrt{\cfrac{1}{2}}\implies sin^{-1}[sin(x)]=sin^{-1}\left( \pm\sqrt{\cfrac{1}{2}} \right)\implies x=sin^{-1}\left( \pm\sqrt{\cfrac{1}{2}} \right)$

$x=sin^{-1}\left( \pm\cfrac{\sqrt{1}}{\sqrt{2}} \right)\implies x=sin^{-1}\left( \pm\cfrac{1}{\sqrt{2}} \right)\implies x=sin^{-1}\left( \pm\cfrac{\sqrt{2}}{2} \right) \\\\[-0.35em] ~\dotfill\\\\ ~\hfill x=\cfrac{\pi }{4}~~,~~\cfrac{3\pi }{4}~~,~~\cfrac{5\pi }{4}~~,~~\cfrac{7\pi }{4}~\hfill$
