Quoting Mir (Reply 16): Hey, I'm not the one trying to one-up people with crazy technical knowledge. I have no clue what that is. My best WAG is some sort of food allergy - I had something like that once (though not nearly as extensive), and it went away in a few days. |

Quoting DocLightning (Reply 32): And the most (academically) appropriate treatment is? The treatment we'd actually use is? |
Quoting AKiss20 (Reply 33): @Doc. Academically use penicillin, clindamycin or erythromycin? |
Quoting ANITIX87 (Reply 34): Standard antibiotics. Pennicilin or erythromycin, IIRC. |
Quoting DocLightning (Reply 36): Penicillin V-K is the most appropriate medication. Erythromycin (really, Azithromycin) is used in the truly allergic patient. In the patient who gets a "rash" for penicillin/amoxicillin, I use cephalexin, which has less than 10% cross-reactivity. Group A Beta-hemolytic strep, which causes strep throat (and thus, scarlet fever) remains exquisitely sensitive to penicillin. That and syphilis are the only two bugs that have never evolved a way around good, old-fashioned Penicillin. However, penicillin oral suspension tastes like fungus and must be dosed three times daily for ten days. So most of us use amoxicillin, which tastes like bubble gum and may be dosed twice daily. |

Quoting KingFriday013 (Reply 4): For #1: Set up two equations: 12x 9y=1410 and x + y=148 Let's simplify the first one to 4x + 3y=470 (divide both sides by 3). And the second one to 3x + 3y = 444 (multiply both sides by 3). Note that both of these have the term "3y" in them. So if we just subtract one from the other (4x 3y) - (3x 3y) = 470 - 444 = 4x + 3y - 3x - 3y = 4x - 3x = x = 26 So we get x = 26. At this point we can just plug in x to our original equation (either one). x + y = 148 = 26 + y Therefore: 148 - 26 = y = 122 So y = 122. Therefore there were 26 adults and 122 children. #2: We know the diagonal is 12. Hence, by the Pythagorean Theorem, which states a2 + b2 = c2, and since the square has four identical sides (i.e., a = b): 122 = 144 = 2a2 We divide both sides by two and get 72 = a2 Take the square root of both sides and we get √72 = √a2 = a Since we have 4 sides, we multiply our value by 4, i.e., 4√72. This further simplifies to 24√2, which is the answer. -J. |

Quoting JetBlue777 (Reply 42): Now that you've mentioned it, they did mess up with the wording, but since it's a NYS Regents Exam, it's pure logic that you have to do all the algebraic steps and equations. Good catch, I shall tell my teacher tomorrow. |
