Since a stop sign is an octagon it has eight sides.  So the perimeter will be:

p=8x,  p=perimeter and x=side length.  We are told that the perimeter is equal to:

16x^2-80x so we can say:

16x^2-80x=8x subtract 8x from both sides

16x^2-88x=0  factor out 8x

8x(2x-11), since we know x>0

x=11/2

x=5.5 units

1/4 divided by 2 = ??
Iteru [2.4K]

Answer:

1/8

Step-by-step explanation:

Hi there!

To divided fractions, you must flip the second fraction and multiply instead.

For example,

1/4 divided by 2 is the same thing as 1/4 x 1/2.

You then multiple straight across to get 1/8.

Really hope this helps!

(1,6)

when x = 2, y = 7

(2,7)

when x = 3 , y = 8

(3,8)

when x = 4 , y = 9

If you use your office computer 40 hours per week, and do not unplug the computer when it is not in use, how much carbon dioxide
dangina [55]
If you use a laptop:  9.25; a desktop with a CRT monitor:  55.51; a desktop with an LCD monitor:  46.26.

A laptop that is plugged up and turned off uses 0.001kw/hr of energy.  Each kwh of energy produces, on average, 1.39 lbs of CO2.  There are 24*7=168 hours in the week; subtract the 40 hour work week from this and we have 128 hours a week for 52 weeks a year:
0.001*128*52=6.656*1.39=9.25.

A desktop that is plugged up and turned off uses 0.004kw/hr of energy.  A CRT monitor uses 0.002 kw/hr when turned off.  This means we have:
(0.004*128*52*1.39)+(0.002*128*52*1.39)=55.51.

For a desktop and an LCD monitor, which uses 0.001 kw/hr of energy, we have:
(0.004*128*52*139)+(0.001*128*52*1.39)=46.26.
