This answer you could put into a google calculator, but I'll save you the trouble and write it all out for you in case you don't know what digit to round to.
8√5.7 = 19.0997382181
There ya go. Glad to help!
Answer:
27.5
Step-by-step explanation:
first you find what 30x30 is as A squared plus B squared is equal to C squared. your A is 12 and your C is 30.
so!
30x30 is 900
12x12 is 144
subtract 144 from 900 and you get 756. once you find the square root you get 27.49. then round up to 27.5
Answer:
5115
Step-by-step explanation:
First of all, we need to assume there is a typo involved, and that the expression is supposed to be ...

The values being summed look a lot like the general term of a geometric sequence:

The exponents in the sum range from 1 to 10, so the values being summed range from 5/2 to 5/1024. In order for that to be the case with our general term, for r = 1/2, we must have a1 = 5/2 as we let n range from 1 to 10.
The sum of the terms of the geometric sequence is ...

The numerator of the fraction is ...
x = 5115

<em>Caveat</em>
If we have misinterpreted the intent of the problem statement, the answer will be different.
For this we start by putting km into cm
53.23 x 100,000 = 5,323,000
Now we divide by 53 to see the total number of revolutions
5,323,000 / 53 = 100,433.962 revolutiona
X = -1 is the answer to -2x2+x+8=0
