Most real number arithmetic is pretty vacuous

That's about as good a way as possible to write this particular real number. But it's far from the only way.

so

Sometimes you can factor something out and you have a common radical:

But most of them are vacuous,

Answer:
The length of the other leg is 8.94 m.
Step-by-step explanation:
Given that,
Hypotenuse of a right triangle is 12 m
The length of the one of the legs of a right triangle is 8 m
We need to find the length of the other leg. It is based on the concept of Pythagoras theorem. Let the other leg is h. So, according to this theorem,

H = hypotenuse = 12 m
b = base = 8 m

So, the length of the other leg is 8.94 m.
Answer:
Step-by-step explanation:
when you are taking (4/10) and dividing it by 2. you have a fraction over a fraction. if you remember what you do to the top part of the equation you do to the bottom. so we want to get rid of dividing by 2. (multiple by the reciprocal) the reciprocal of 2 is 1/2. that will cancel out the bottom part of the equation but what you do to the bottom you have to do to the top. so, (4/10) * 1/2 is the same as (4/10) divided by 2. hope that makes sense. it's much easier to write out then type math...
Volume of a cylinder = PI x r^2 x H
r = 4 so r^2 = 4^2 = 16
h = 3
Volume = 3.14 x 16 x 3 = 150.72 ft^3
it doesn't say how to round the answer so you may need to round it
I belive the answer is 240 because there are 4 C in a L so what I did was 4×60 and I got 240 cups
