Answer is d. i.e. 3\nn(A U B)') = 15 => n(A U B) = 50 - 15\nThus n(A U B) = 35\n\nDefinition of n(A n B') can be summarized as elements of A that belong to no other set but A. \n\nSo, Out of the n(A U B) = 35, 32 belong to B, which means that 3 belong to A and A alone.

I assume DH is delta H ? If so - it's the change in heat. Final minus initial.

It means a number between 5 and 200.  You might have to round to the nearest number if it doesn't take decimals.

It's bringing the √2 out from the brackets. \n\nMultiply 1+(3/2) by 2... what do you get? 2+(3)\nMultiply 1+(√3/2) by √2.. what do you get √2+(√3)

2 - 28 x 78 - 89 + d = 34\n\n2 - 2184 - 89 + d = 34\n\nthen D = 2305\n\nYou follow the order of operations.  PEDMAS  parentheses, exponents, multiply, divide, add subtract.  Therefore it's 2305.

Well, 2*29=58=1 (mod 57), and 52=26*2, so 52*29=26*2*29=26*1=26 (mod 57).

Uhm you are vague by saying "at least $30". Hence, it is impossible to figure this out. You did not say "exactly $30".

It refers to multiplication.\n\nFor example, the product of 4 and 3 is the same as saying 4 multiplied by 3, and the answer of course is 12.

To a mathematician 1 + 1=2 right. If I were using that equation in another context it could be interpreted differently. In a nutshell the quote is saying that people sometimes interpet the same one thing differently.

d/F = 0.8\nso d = 0.8F\n\nWhen F = 25\nd = 20\n\nWhen F = 40\nd = 32\n\nSo 20 ≤ d ≤ 32
