the area of your roof is equal to the base (B) times the hight (H) divided by 2.
A = ( B x H )/ 2 = 120
To get the Perimeter of your roof you need to sum the base plus the sides (S)
So P = B + 2 x S
if you have a slope degree of 30 then
B/2 = cos (30) x S
so P = B + 2 x B / 2 / cos(30)
P = B ( 1 + cos (30) )
we also know that
H = tg (30) x B/2
from this last one we can go back to the Area and get a value for B
120 = ( tg (30) x B / 2 x B) / 2
480 x SQRT(3) = B^2
B = SQRT(480/tg(30))
So:
P = SQRT(480/tg(30)) x ( 1 + cos (30))
tg (30) = 1 / SQRT(3)
cos (30) = SQRT(3)/2
P = 2 SQRT(30 x (12 + 7 x SQRT(3) ) ) or aproximately 53.8m

How do I reset my TI-86 after a long period of no use.
Every time you change batteries this will happen to you. First press 2nd then press and hold the down arrow. Hold until their is no black in the background but you can still see the numbers on the screen.

Hi,
It has two batteries CR2032. They should not be removed at the same time. There must always be one battery in the calculator. The calculator should be turned OFF when changing batteries.
Often after you change batteries the screen contrast may be too light and you cannot see anything. The contrast can be adjusted (lightened or darkened). As you adjust the contrast setting,a highlighted number in the upper right corner changes to indicate the current contrast setting; 0 is the lightest, and 9 is the darkest.
To adjust the display contrast:
1. Press and release the [2nd] key.
2. Use one of two keys: (UpArrow or DownArrow)
--- To increase the contrast (darken), press and hold [UpArrow]
---To decrease the contrast (lighten), press and hold DownArrow
Hope it helps.
Thank you for using FixYa.

Screen Gibberish
Wow, I'm in the exact same situation. I've had my trusty TI for 6 years and now all of a sudden this gibberish is on the screen. You're right, there is absolutely nothing you can do to fix it. Guess we'll have to bite the bullet and buy a new one.

How many ml is 5 mg?
Milliliter is a unit of volume, milligram is a unit of mass (or weight). There is no direct conversion between them.
5 mg of water occupies 5 ml. 5 mg of gold occupies about about a quarter of a ml.

Answer always appearing
Minus and change-sign are two completely different things. Minus is used to subtract one number from another. When you press minus when the input line is empty, your telling the calculator to subtract. The only way it can subtract the number you're about to put in is to subtract it from something else, and that something else is the previous answer, hence the "Ans."If you want to input a negative number, use the change-sign key. If you want to subtract one number from another number, use the minus key.Try pressing the plus key when the input line is empty. You'll get Ans+ in this case as well, The same with multiply and divide, among others, and for the same reason.

How can you program games
Do not even go there. The calculator is pretty basic and does not have memory to store instructions. If you want to take up programming ( a worthwhile endeavor) buy a graphing calculator such as a TI 89 itanium, a TI Voyage 200PLT, a TINspire, or a Casio Graphing calculator FX 9860 SD, ClassPad 330, or some top of the line HP calculators (HP 49G+, HP 50 G).

Texas Instruments TI-5045 SV paper won't advance
The foam on the feed roller is probably decayed/ soft. Which has caused the plastic gear that engages that drive gear to wear. If the gear is moved/ spaced over to pick up the 40% that isn't trashed - it'll feed.
I'm going to try to fix my Goodwill purchase anyway. Anything is better that the Canon piece of rubbish I have now. Mybe someone can tell Canon that a few months of use is not enough?
