17 ½ % of 240
First option
Change  the fraction ½
to a decimal. It would be 0.5 ( 1 divided by 2)
½=0.5
You will add the whole number 17 to the result.
17 + 05 = 17.5 
Now you will divide by 100 (percent)
17.5 /100  To divide a
decimal by 100,  move the decimal point two
places to the left.
17.5 /100 = 0.175   times 240
0.175 x 240 = 42
Second option
Change the percent to an improper fraction
17 ½= 35/2 (you have to multiply (2 x 17) plus 1 equals 35
over 2 ( keep the denominator). It will be 35/2.  Put the other number (240) over 100 and
multiply. 
35/2 x 240/100 = 42 
There is another way . You can simplify
Cancel all the zeros that you have and start to reduce.

Answer:
It is right
Step-by-step explanation:
square all sides
we have 16, 32, 48
add the two shortest sides, which equal the third side
the triangle works with the pythagorean theorem, so of course it is right :)
 
        
             
        
        
        
Answer:
x = (+ - ) 9
Step-by-step explanation:
x^2 = 81
u know how u can sometimes cancel something out by doing the opposite. 
This is one of those times as well. the opposite of ^2 = square root. 
so if we take the square root of both sides, this will cancel out the^2 on the left side.
sqrt (x^2) = sqrt(81)
x = (+-) 9.....thats a positive and a negative sign...because the sqrt of 81 is both 9 and -9.
