The rate equation is rate = k(CO)^x(O2)^y. Divide rate 2 by rate 1. 0.226/0.113 = 2 and 2 = (0.300)x(0.150)y/(0.150)x(0.150)y Note that 0.150y cancels with 0.150y and leaves just 2= (2)x and x must be 1. Do the same thing for rate 3 divided by rate 2 and determine y. You ...

6 is not a factor of 325 6 = 2*3 25 = 5*5 two factors 2*3*5*5 = 150 that is 4 factors for total of 6 then 10 30 15 75 another 4, now 10 now include 1 and 150 for 12 so I think 150

the planes' distances from p form a scaled-up 3-4-5 right triangle, so at the time specified, d, the hypotenuse, is 250 at time t hours later, d^2 = (150-450t)^2 + (200-450t)^2 That's kind of nasty, so a simpler formula would be, Let x be the distance of the first ...

eh? Seems to me that at each vertex the interior and exterior angles sum to 180. So, interior is 150, exterior is 30. If the interior angles are 150, then we need to find an n such that n*150 = (n-2)*180 30n = 360 n = 12 So, a dodecagon has interior angles of 150 and exterior ...

according to my rough sketch the second course makes a 100º with the first course. so by the cosine law x^2 = 200^2 + 150^2 - 2(200)(150)cos 100º solve for x (I got 270.03, but check my arithmetic) then by sine law, the angle opposite the 150 is sin(theta)/150 = sin ...
