Step-by-step explanation:

we know that

In the right triangle QRS

$sin(R)=\frac{SQ}{QR}$ ----> by SOH (opposite side divided by the hypotenuse)

substitute the given values

$sin(31^o)=\frac{SQ}{46}$

solve for SQ

$SQ=\frac{SQ}{46}sin(31^o)=23.7\ ft$

Jacob uses 5/6 of a liter of water to fill 4/7 of the fish aquarium. how many liters of water are needed to fill the aquarium?

Rom4ik [11]

1 - 4 / 7 = 3 / 7 ( It means that it is 3 / 7 of the aquarium left to fill with water )
5 / 6 L ------ 4 / 7
x L --------- 3 / 7
5 / 6 : x = 4/7 : 3/7
5 / 6 : x = 4 : 3
4 x = 3 * 5/6
4 x = 15/6
x = 15/6 : 4
x = 5/2 : 4 = 5/8 L
Answer:
Jacob needs 5/8 L more to fill the aquarium,
or 5/6 + 5/8 = 35/24 L ( in total ).
