Answer: $2.35
Explanation: You make 12 cards an hour and work for 8.5 hours so you would make 102 cards per day because 12x8.5=102. 102x5= 510. You would make 510 cards ever work week. 1,200 (the amount you need to make per week) ÷510(the amount of cards you make per week)= 2.35. You should sell 1 card for 2 dollars and 35 cents if you want to make around 1200 dollars per week.

Explanation: I hope that helped !!
Answer:
1.53 atm
Explanation:
From the question given above, the following data were obtained:
Volume = constant
Initial pressure (P₁) = stp = 1 atm
Initial temperature (T₁) = 273 K
Final temperature (T₂) = 144 °C = 144 °C + 273 = 417 K
Final pressure (P₂) =?
Since the volume is constant, the final pressure can be obtained as follow:
P₁ / T₁ = P₂ / T₂
1 / 273 = P₂ / 417
Cross multiply
273 × P₂ = 417
Divide both side by 273
P₂ = 417 / 273
P₂ = 1.53 atm
Therefore, the final pressure (i.e the pressure inside the hot water bottle) is 1.53 atm.
Answer: Volatile
Explanation:
like ethanol(alcohol) it evaporates when you put it in the hand, really fast.
Some people think that it dries when it really evaporated at room temperature from liquid to gas
