9.1 is less than half of 3576, so it's going to round down to
0. (mental math)
<em>I'm not sure if you were also asking for the actual value because of the wording, so here it is if you need it</em>.
As a fraction,

.
(multiply both the top and the bottom by 10)
As for the actual decimal value, it's something like 0.0025447....You can find this out using long division (you're going to have to know the multiples up to 10 of 3576, so list those off to the side) or simply a calculator. As for handling the decimal, just divide into the 9.1 like a normal number (only the digits are important when you're doing the long division) and bring up the decimal point when you're done. You might also need to use zeroes as placeholders. (9.1 = 9.10000...)
The answer is 8 because 16^1.5 is 64 and 64^.5 is 8
A square will have the same length and width and area= length times width. its set up in a 4x4 square because there are 16 squares total; 4 across and 4 down. if the sides are 4 miles each then one whole side will be 16 miles. so the equation is 16 times 16 which equals 256. so the answer is 256 square miles.
The correct answer is 64 bc 6 times 6 is 64
It would be the second option.
Good luck :D
