<em>Additional comment</em>
The (3, 4, 5) Pythagorean triple shows up in numerous algebra, geometry, and trigonometry problems. This is one of them. Once you identify the magnitude of v as the hypotenuse of a triangle with legs 3 and 4, you know immediately that ||v|| = 5 and ||3v|| = 15.
10 inches...................7 days
x inches......................24 days
x=24*10/7=240/7≈34,28 inches
The amount of kilograms he weighs I think is 57.6062994983
Ok. So first, we need to set up the proportion.
64/8 = x/1
Now, we can cross multiply
64*1 = 8x
64= 8x
8x/8 = 64/8
x= 64/8
Now we have to divide 64 by 8.
x=8
Our final answer: The unit rate is 8 ounces per cup.
