Acan of soft drink at room temperature is put into the refrigerator so that it will cool. would you model the can of soft drink as a closed system or as an open system? explain.

closed System

Step-by-step explanation:

Metal is a conductor of heat, coolness, and electricity. In terms of electricity, only closed circuits will work because electricity flows in a closed loop. If the can is being cooled successfully, then the heat is flowing out of the can into the fridge while cool air from the fridge is flowing into the can forming a loop. So the answer is a closed system.  

the answer will be b x² +x-1

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
