I'm assuming that you want to know how many hours until they are the same temperature. Here is the equation you can use to figure it out:
40 + 5h= 340-45h
Here is how I would solve it:
40+ 5h= 340 - 45h
+45 h + 45 h
40+50h= 340
-40 -40
50h= 300
/50 /50
h= 6
It will take 6 hours for the two appliances to reach the same temperature, assuming the power doesn't go out. For reference, they would be at 80 degrees.
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
use Cos for y .... b/c we see that function above has all the pieces we are going to work with
use Sin for x .. for the same reason above
Cos(30) = y / 4
4Cos(30) = y
4/2 = y
2 = y
leave the answer for y like that.. it's in 'exact" form
now for x
Sin(30) = x / 4
4Sin(30) = x
4* 1/2 = x
2 = x
and leave your answer for x like that as it's in it's exact form. :)
oh and I see the answer in the list.. do you? :)
