How do i calculate the ratio for 64,000 8:5:3?

8+5+3 = 16

64,000/16 = 4000

4000*8 = 32,000

4000*5 = 20,000

4000*3 = 12,000

so 32,000 : 20,000 : 12,000

Your best bet would be trying a math package on ti-calc.org - you can usually find something that does what you want there. You'll need a cable and the software to download these programs to your calculator. Here's a link to the trig section:

Hi Heavenknows9,

The advantages of a basic calculator is that it saves valuable time for productive learning, especially at a higher level where the basics has been mastered, and more emphasis is placed on concept understanding. Only upon achieving the objective, can the teacher allow them to use back the calculator to move forward to other topics. This ensures that no part of the math education is missed out. Thus, calculator, though may seem detrimental to math studies, can be beneficial when the intent of usage is proper.

TWO THINGS YOU NEED TO KNOW, Eli.1. Secant will NEVER return a degree measure (or even a radian measure) no matter what computer or calculator you use. The reason is because secant returns the ratio of sides (hypotenuse over adjacent), which has a range of and find its reciprocal (ie, flip the number upside down: the reciprocal of 5 is one-fifth). That's all.B. TI-84 only uses the three basic trig functions. Secant is the reciprocal of cosine. Therefore, in order to find the secant of -1.2 radians you need to be in Radian mode (see #2 above). From there, you just find the cosine of -1.2 and take that values reciprocal (ie, flip the number upside down: the reciprocal of 10 is point one) . That's all. Math lesson: 1 Radian = 180 Degrees. Therefore, 1.2 Radians is roughly one-third of pi, therefore it is roughly one-third of 180 degrees; therefore -1.2 radians would be nearly -60 degrees (a very friendly angle measure). I hope that helps If not, you should call Texas Instruments because they've got friendly people who are happy to assist anyone. Questions like this are right up their ally, advanced questions like the syntax of the poisson cumulative distribution function are not. So, you're fine. For in depth math help holler at www.THEMATHCHEETAH.comIn Short: Secant returns ratios and NOT degrees or radians. Secant is the reciprocal to cosine. Arcsecant WILL return degrees/radians. Your calculator can be set to either mode.TEXAS INSTRUMENTS >>>>> all calculators ever made.

Cristina,

You might be referring to something else, so let me try to knock out two birds with one stone.

The arcsine function is the inverse sine function. It will take a ratio input and produce a degree/radian output. It isn't exactly transforming anything into degrees. Instead, it is telling you the corresponding angle that goes with the ratio of opposite over hypotenuse (your input).

With that said, I am going to try to answer your question with two possible solutions.

1. To find the arcsine of a value/input (between -1 and 1) you simply have to press {[2ND]} {[SIN]} {["NUMBER"]}. For example, if I wanted the arcsine of one-half I would press {[2ND]} {[SIN]} {[.]} {[5]} {[=]}. The computer would display 30 (degrees) because the sine of thirty degrees is one-half, therefore the arcsine of one-half is 30 degrees. Inverse functions in math are often written with a faux-exponent of negative one. Inverse sine (ie arcsine) should be written in blue above the sine button on your calculator.

2. To convert a compass reading into a concrete degree measure you will NOT use arcsine. Instead, you can use the Degree-Minute-Second key which is on the TI-30X. The degree portion is naturally symbolized by the superscript o; the minute is symbolized by the single apostrophe mark, the second symbol is the quotation mark. So, to convert a compass reading of 10 degrees-30 minutes - 30 seconds you would type {[10]} {[o ' "]} {[=]} {[30]} {[o ' "]} {[ -> ]} {[=]} {[30]} {[o ' "]} {[->]} {[->]} {[=]} {[=]}. The calculator should display 10.50833333, which represents the hardcore angle measure that corresponds with 10-degrees-30minutes-30seconds. Also, it should be known that this is a much better thing to do by hand because it will deeply ingrain the basic mathematics going on. Even though we're talking about degree measures, the minutes & seconds are still at a 60 unit benchmark: meaning that there are 60 minutes in a degree and 60 seconds in a minute. Therefore, 30 minutes & 30 seconds is 30.5 seconds, which is 50.83333 percent of 1 degree. Thus, 10.5083333 degreeees. Also, you can think of it as 3600 seconds in a degree, therefore you had 1830 seconds which equated to 50.83333% of 1 degree. Thus, 10.50833333 degrees total.

Alright...I hope that helps you with either question you might have been referring to. Also, I hope you enjoyed the minor math lesson involved here. Maybe you already knew it. If that was the case then I am sorry. Either way, I own a TI-30XB Solar (among many other TI Calculators) and I highly doubt that the buttons on my calculator are starkly different from yours.

If you have more calculator or even math questions just post them on here and I'll hack away.

Arrivederci.

Technically a fraction is just the ratio of two integers (division of two integers). To enter a fraction, type in the numerator, press the division key, then enter the denominator.

The problem is preventing the fraction from being evaluated. To do that press [MATH] key, select [1:

A fraction is in fact a ratio of two number: a division of a numerator by a denominator. The key used for the division operation is the one above the multiplication sign and below the caret [^], and in thee rightmost column of keys.

Beware that this calculator converts any ratio of two numbers into a decimal value. To keep a fraction in a fraction form you must use the [|=>Frac] or [ToFrac] command. To convert a decimal result to a fraction, use the [|=>Dec] command.

These commands are accessible through the CATALOG or more easily by pressing [MATH] (under the ALPHA key) and selecting [1:|=>Frac], or [2:|=>Dec]

Ex: to keep 27/48 in fraction form you enter

27 [/] 48 [MATH][1:|=>Frac] [ENTER]. Result is 9/16

You will notice that the resulting fraction is reduced to its simplest form.

To convert the above result from fraction to decimal press [MATH][2:|=>Dec]

A fraction can always be approximated by a decimal value but the converse is not always possible.

Hi,

The calculator has two Input/Output modes: MthIO and LineIO. Since I do not know exactly what you mean by "basic math" mode or "basic form" I must summarize some properties of each mode so that you can recognize your "basic math" mode.

To set the LineIO as the default, you press the key sequence: [SHIFT][MODE] (SETUP) and select [2:LineIO].

Hope it helps.

Thank you for rating the solution.

- In MthIO, you have access to the multistory templates to enter fractions with a horizontal fraction bar etc. the exponents for the powers are raised above the main line, etc.
- In LineIO, what you enter in calculator is all on the same line, fraction and radical results are displayed as decimal numbers, etc.

To set the LineIO as the default, you press the key sequence: [SHIFT][MODE] (SETUP) and select [2:LineIO].

Hope it helps.

Thank you for rating the solution.

You basically do your math like this:

Problem 1/2 x 2/3

Enter it in the calculator as (1/2)*(2/3) [Enter]

Then press [MATH] and select "ans>frac"

ratio: a comparative value. "so many pounds to ounces"

i.e. 3 to 1

proportion: a part of the original. a percentage of the whole.

i.e.: a proportional band of a thermostat. that "dead zone" between the set point and the desired point is 10 degrees.
