Answer:
66
Step-by-step explanation:
57 x 2= 114
180-114= 66
To solve we have the following equation below,
Assumption: Line of reference is the surface of the water.
Final distance between Jana & fishing line = (dock height) +(reels out) -(reels back)
Final distance between Jana & fishing line = 10 + 35+ 29 - 7 = 67 feet
<em> ANSWER: 67 feet</em>
<span>THE AREA OF THE ROOM IS :A=4*2.4=9.6 m^2
THICKNESS t=0.30 m
DIFFERENCE IN TEMPERATURE dT=18-6=12
q=kAdT/dx=kA*dT/t
q=1.3(9.6)(12)/0.30=4992 W=499.2 J/s
In 1 hour or 3600 sec
P=q*T=(499.2 J/s)(3600 s)=1797120 J=1.8 MJ
1.8MJ OF HEAT FLOWS HTROUGH THE WALL IN ONE HOUR</span>
5 * 1/2 - 8 ( 3/4 * 1/2 + 1/2 )
5/2 - 8 ( 3/8 + 1/2 )
5/2 - 8 ( 7/8 )
5/2 - 56/8
-36/8 = -9/2
A is the answer
