Sorry to say, soweeto54, but that question you've posted does not make much sense. It can be interpreted in three different ways, neither of which can be gleamed with much confidence. Yet I will still offer you three valid answers for your TI-83,

"The percent of 140 from 762.9 =". The troublesome part is the "from". Percents questions should be written in terms of "is" and "of".

TWO INTERPRETATIONS.

RESPONSE 1. The question could be read as "what percent of 762.9 is 140?". To do this on your calculator you simply do 140 divided by 762.9. From there, you simply move the decimal point two digits to the right to convert it into an equivalent percentage. So, that should be [1][4][0] [/] [7][6][2][.][9] [=] on your TI83. This was an example of a "percent of" question.

RESPONSE 2. The question could be read as "what percent of 140 is 762.9?" To have your TI83 calculate this you simply do 762.9 divided by 140. Of course, you will then need to move the decimal over two spots to the right in order to turn it into an equivalent percentage. Yes, it probably is strange to think of a number being more than 100 percent of another but it is a valid statement which occurs in the real world every single day. Nonetheless, for your TI83 you just press [7][6][2][.][9] [/] [1][4][0] [=]. This was another example of a "percent of" question. In fact, this is just the decimal reciprocal of the previous answer.

RESPONSE 3. The question could also be read as "140 from 762.9 will leave me with what percentage?" IE, 762.9 minus 140 will yield a number which is "x" percent of the original. Here, you would just do 762.9 minus 140, then you would take that answer and divide it by 762.9. From there, you'd do the old usual and move the decimal over two spots to the right for a percentage result. So, for your TI83 you'd do [(] [7][6][2][.][9] [-] [1][4][0] [)] [/] [7][6][2][.][9] [=]. Viola. This was an example of a "percent change" question. In fact, this is just the complement to response number one.

Users may need individual key of "%" for various calculation purpose like other calculators.

### Can my 1999 Cadillac Seville concourse overheat by mixing too much water with antifreeze??

Theoretically yes. Antifreeze has a higher heat capacity than water. Basically, a liter of antifreeze can hold more heat than a liter of water. I dont think it would be enough to cause an overheat though

### Percent of increase

change =(new value-old value)/(old value)
Percent change =change*100 %
change=(8900.00-8640.00)/8640.00=0.0301
Percent change=0.0301*100%=3.01%
Since the change is positive, the new value is higher than the old value, this change is an increase.
Percent increase=3.01 %

### How do u get % on it

On calculators you do not usually get percents. Instead, you get values which can be converted to a percent. For example what percent is 245 out of 987. You divide 245/987=.248. This is essentially the same as saying 24.8 percent. You move the decimal over 2 values. You can also round to get a nice percent number such as 25 percent.
If you are trying to put in a percent lets say you have to find 47% of 80. You just multiply .47 * 80= 38.4

### I raised \$948,963 last year. I raise \$ 817,430 this year. Is that 9% less raised this year>

No.
You can divide this years by last year and that gives you the percent you got this year compared to last. You raised about 86 percent of what you raised last year. so 100 percent minus 86 percent. That is equal to 14 percent. You raised 14 percent less this year.

### Increase percentage of 70 to 200

A percentage increase from a value a to a value b is defined as
Percent increase=(b-a)/a*100 percent.
In your case it is (200-70)/70=1.857. Multiply this number by 100 and append the percent symbol. Thus increase=185.7 percent or about 186 percent.

DTC Set Criteria (2.4L)

Engine is in closed loop control. Intake air temperature is more than 14°F (-10°C). Barometric pressure is more than 11 psi (76 kPa). Volume Airflow (VAF) sensor output frequency is 88 Hz or more. Code will set if long-range fuel correction is less than -12.5 percent, or more than +12.5 percent, for 5 seconds and short-range fuel correction is less than -10 percent, or more than +10 percent, for 5 seconds.

Code will set if long-range fuel correction is less than -12.5 percent, or more than +12.5 percent, for 5 seconds. On 2.4L code will also set if short-range fuel correction is less than -15 percent, or more than +15 percent, for 5 seconds. On 3.0L Federal code will also set if short-range fuel correction is less than -13.5 percent, or more than +13.5 percent, for 5 seconds.

Have the O2 Sensor changed on the Right Bank, ( passenger side of the Engine, or where the # 1 cylinder is.)
Good luck and hope this helps
