A three of a kind always beats a two pair.
YES
4194304 = 222
You can use three 2s to make 26 as follows (2x2)! + 2 = 26 So you can simply make 26 with five 2s as (2x2!) + 2 - 2 + 2 = 26
The 1S orbital will hold the innermost pair of electrons.
No, the higher ranking pairs in each hand have priority and are compared first and a pair of Aces beats a pair of Kings. The value of the lower pair is only relevant if the higher pairs in each hand are the same, for example KQ v K7. In this example the lower ranking pairs in each hand would be compared and because a Queen is higher than a seven, KQ beats K7.
Take $10 off the boots cost to get down to twice the cost of the shoes, and then halve that number to get the shoes cost: $76.50 - $10.00 = $66.50; half of that is $33.25. Algebraically, represent your knowns and relationships as equations and then solve them simultaeously for s: * b = 76.5; 2s + 10 = b * 2s + 10 = 76.5 * 2s = 66.5 * s = 66.5/2 * s = 33.25 dollars
2s 3d = two shillings and threepence (often 'thruppence'). Alternatively, 'two and three'. (Postscript. The UK adopted the present decimal currency on 15 February 1971).
Orbital interactions with each other produce bonding. Single covalent bonds occur when 2s orbitals overlap and combine around the nucleus.
4s2 - 9 can be expressed by using the identity: a2 - b2 = (a-b)(a+b) Therefore, 4s2 - 9 = (2s)2 - 32 = (2s-3)(2s+3)
The equivalent of 7s plus 2s is 9s.
2s - 12 + 2s = 4s - 124s - 12 = 4s - 124s = 4ss = s==========this is an identity and any number can be s
2s + 16 = 4s - 6 Subtract 2s from both sides: 16 = 2s - 6 Add 6 to both sides: 22 = 2s divide both sides by 2: s = 11
