Answer is A because when you work it out the area is 110.500 and rounding it makes it -
Let n be the man's walking rate. Then:
9/n+9/27=3&1/3
243+9n=90n
243=81n
n=3
The man's walking rate was 3 mph

It takes him 17 minutes to make each shoe.
<em>How to Solve: </em>
- take away the 30 min lunch break from the time becomes 11:45 to 4:00
- calculate the distance from 11:45 to 4:00 which is 4 hours and 15 minutes to complete each shoe.
- Convert the hours into 60 minutes each so 60*4= 240 now add the extra minutes 240+15= 255 minutes
- Now divide that bye 15 shoes 255/15= 17 minutes
- So it takes 17 minutes to make each shoe. :)
Easy
quadratic means 2nd degree
means highest power of exponent is 2
so like x^2
first one
we have 3x^3, that is 3rd degree,nope
2nd one
we have 8x^4, nope, that is 4th degree
3rd one
we have -x^2, yep
4th one, we have 9x^4, that is 4th degree
answer is 3rd one or p(x)=-5x-x^2
8x - 32 = 6 - 9x
17x = 38
x = 38/17
