3 ft* 12 inches in a ft= 36 inches total
8/36= 2/9
Final answer: 2/9
F x (x + h) - fx/h
fx +fh - fx /h
fh/h
f
So f is the answer
3x+8x=3333
11x=3333
X= 303
Boys 3x,so 3*303=909
This is quite simple. We will first add the amount of miles walked together.
3.25+5.5=8.75
Then we will divide 175 by the number of miles walked which in this case is 8.75.
Then we get 20 which is the amount of money that his parents donated for every mile that he walked.
5π/12 = (5 · 180°) : 12 = 75°
cos 75° = cos ( 45° + 30° )= cos 45° cos 30° - sin 45° sin 30° =
=√2/2 * √3/2 - √2/2 * 1/2 =

=(2.4495 - 1.4142): 4 = 0.258825
