Question about PC Desktops

1 Answer

Help........Before midnight tonight

Measure the distance of the diagonal (from one corner to the opposite corner) of the screen on your computer monitor to the nearest tenth of a centimeter or sixteenth of an inch. Measure the height of the screen along the vertical as well. Use the Pythagorean theorem to find the width along the horizontal In your post, include the length of the diagonal, the width, and the calculations needed to determine the horizontal length of your computer monitor. After you have calculated the approximate length using Pythagorean theorem, use a measuring device to measure the horizontal length of your monitor. Was your measurement close? Why might the measurements not be exactly the same?
Typing hint: Type Pythagorean theorem as a^2 + b^2 = c^2. Do not use special graphs or symbols because they will not appear when pasted to the discussion board.

a^2 + b^2 = c^2

diaganol: 15 3/4
height: 9 3/4
horizontal: 13

    I am uncertain on how to work this problem. I know the equation is



    a^2 + b^2 = c^2



    a^2 + 9 3/4 ^2 = 15 3/4 ^2 (I don't know how to complete the problem from this stand point)

    The Pythagorean theorem: The sum of the areas of the two squares on the legs (a and b) equals the area of the square on the hypotenuse (c). Why do you need that to figure the horizontal lengh? this is .
    CIRCUMLOCUTION - a roundabout or indirect way of speaking; the use of more words than necessary to express an idea. So , what is it you really need to know?

Angel repeatedly asks for discs to do a system recover


Are you the original owner? If you did not make a set of recovery discs, you may have to go to emachines and order them. They are about $20. I recently refurbished an emachine and that is what we had to do.
You will need the model number and serial number. They cannot download it to you either.

I need to reformat my emachines m2350.


Hello,

If you want to restore the machine to factory state I would suggest using the restore disk that came with it originally.

You possibly will need to go into your particular bios and set the boot option to start with the cd and then save and restart with the first cd in the drive. From that point you will need to follow on screen prompts to start the restore.

If you do not have the Cd's you can contact Emachines to order a replacement. You can contact them with the information below:

They also have a chat option available from https://support.gateway.com/Support/copilot/en/us/chat_us_em_tech.asp

Thanks and remember to rate this solution.

How do i get to the ram on my acer aspire 3100 to upgrade my ram


Turn the computer off, then turn the computer over with the screen shut. Take a screw driver and un-screw the memory housing (that is the big part.) It is the opposite corner from the battery. Be sure to unplug the ac adapter, and remove the battery. Your owners manual will tell you how to do it. If you don't have it you can download it from Acer Support.

Toshiba equium L10-300 problems


Hey there stuart cdm, the task bar problem can be solved by scrolling down to the taskbar and right clicking on it to reveal a box which has properties listed on it. Left click on properties, and choose your options, you can uncheck the keep the taskbar on top of other windows option. You should also experiment with the other options checked to see which ones you prefer.
The size of the internet screen can be adjusted by clicking on the box next to the red X at the top right corner. then move your pointer to the right or left edge of the window and go back and forth until the arrow appears. When the arrow is visible, hold down left button on the pointer, and slide side to side until you get the size you prefer. You can also do this for the top or bottom, or on corners it will give you a diagonal arrow and allows you to expand or shrink the window easily. You can use this function to adjust the window size for any function and your pc should remember your last setting and keep it until you change it again. Good Luck!

Dear spinnerrr

  • Multiply the wheel diameter in mm or cm by 3.14.
  • Measure the distance travelled in one complete turn of the wheel.
this is the four digit number you are looking, it should be between 2145 and 2149
