54.725 = 54 + 725/1000 = 54 + 29/40 = 2189 / 40
Thanks for that excellent answer, LordEnedar....!!!!
75 / 6 = 25/2 = 12.5 cents per apple
Can you take it from here????
Notice that
(cos x - sqrt(3)/2) = 0 add sqrt(3)/2 to both sides
cos x = sqrt(3)/2 and this occurs at 30 degrees and at -30 degrees....or ....in general terms...
x = +/- 30 + n*360
Make sure your calculator is in degree mode....and you will find that sin(30) [ cos (30) - sqrt(3)/2 ] = 0
Let x be the number that she baked.....and we have
[3/5]x = (1/4)[2/5]x + 200 simplify
(3/5)x = (2/20)x + 200
(6/10)x = (1/10)x = 200 subtract (1/10x ) from both sides
(5/10)x = 200
(1/2)x = 200 multiply both sides by 2
x = 400
You're welcome, kasper....
x^2 - 6x + 9 = (x - 3) (x - 3) = (x - 3)^2
We need to know another side or angle if this is not a right triangle....or.....if it is a right triangle....are these two legs......one leg and a hypotenuse ???
sqrt[34^2 - 16^2] = sqrt[900] = 30 ft
200/6 = 100/3 = 33 + 1/3
