Answer:
13/48
Step-by-step explanation:
I take the middle sign to be plus.\
3/4//4/5 = 3/4 * 5/4 = 15/16
15/16 - 2/3 =
The lowest common denominator would be 48: 16 and 3 are prime to each other.
45/48 - 32/48 = 13 / 48
Where did the minus come from? I take it that there is a minus sign in front of the 2

The total weight was 10.65
Explanation: Since there is only one number in the hundredth place, i didn’t need to add. Instead i put that number as my hundredth place AKA 5. then i added the tenth place which was 5+7+4 which = 16. i carried the one over. then i added the ones place. 4+2+3= 9. the one i carried over got added to the 9. therefore my final answer was 10.65
Answer:
73.5 kJ
Step-by-step explanation:
Mass of butane = 185 g
Heat of vaporization for butane = 23.1 kJ/mol
Molar mass of butane = 58.12 g/mol
Number of moles of butane = 
Energy required for burning 185 g of butane = 3.18×23.1 = 73.5 kJ
∴ Energy is required to vaporize 185 g of butane at its boiling point is 73.5 kJ
Use the Pythagorean Theorem: A squared + B squared = C squared to find the hypotenuse of the triangle for each problem
