SPL-P100 calculator problem

I cannot get my calculator to NOT round up or down when doing ANY kind of math on it, ie: 15 divided by 2 does not equal 7 however that's the answer I get. I need it to post answers and figure with 2 decimal places. How do I get the settings to this? I do not have a book with this calculator as it was here at the job from the previous employee.

There is a tab button that controls the amount of decimal places you would like. press tab and it will change to 0-2-3-4-A-F showing on the bottom of the screen.

It works. :-)

    Dear Joe Stogrin -- Thanks so much for adding the answer to this question. I was going crazy trying to figure out how to do it. And the 'manual' does not mention it at all.

All these answers are for square objects. How do I find the measurements of a round object, i.e. a cement mixer?


Hi Debbie:
You still get to use your calculator, but you need to use the mathematical formulae dealing with circles.
Area = pi times r squared
Volume of a cylinder = Area (of one end) times length.

For your cement mixer, (Average the diameter for simplicity)
All of the measurements need to be in the same units, lets use inches, then convert it to cubic feet.....
the volume would be:
pi (22 divided by 7)
times
1/2 diameter
times
1/2 diameter
times
depth

For my ancient mixer that would be:
22 / 7 x 10" x 10" x 22" = 6,914 cubic inches
1 cubic foot equals 12" x 12" x 12" equals 1728 cubic inches.
6,914 divided by 1728 equals 4 cubic feet.

Now we don't fill it right up, but that is its capacity.

Hope that helps.
By the way, my mixer likes 10 shovel fulls of navvy, 2 shovels of type 10 cement, and about 2 quarts of water to get a nice mix.
I do the water first,
then 5 navvy
then 2 cement
then another 5 navvy,
then just enough water to get the right consistency.
Cheerfuls!

2x plus 5y equals 7 3x plus 6y equals 3


1) 2x + 5y = 7
2) 3x + 6y = 3

I'm going to use the method of elimination to solve for x and y.
Multiply 1) by 3 and 2) by 2 to allow the x's to be eliminated.

1) 6x + 15y = 21
2) 6x + 12y = 6

Now subtract line 2 from line 1.

0x + 3y = 15
---- ----
3 3 divide both sides by 3 to get y by itself.
y =5.
Substitute into 1) to calculate x.
2x + 5(5) = 7
2x + 25 = 7
2x + 25 -25 = 7 - 25
2x = -18
---- ----- divide both sides by 2 to get x by itself
2 2

x = -9

Check by plugging in answer into the other equation, in this case 2)

3 (-9) + 6(5) = 3
-27 + 30 = 3
3 = 3
We did it correctly and checked to prove that we did it right.

Good luck.

How do I change a percentage to a fraction

How to convert percent to fraction

  1. Divide the percent by 100 to get decimal number.
  2. Count the number of digits (d) to the right of the decimal point of the decimal number.Example: 2.56 has 2 digits to the right of the decimal point, so d=2.
  3. Calculate the factor (f) for making the decimal number an integer: f = 10 to power d
    Example:
    f = 10 power 2 = 100
  4. Multiply and divide the decimal number x by the factor f: x * f / f = y / f
    Example:
    2.56 * 100 / 100 = 256 / 100
  5. Find the greatest common divisor (gcd) of the fraction. Example:
    gcd(256,100) = 4
  6. Reduce the fraction by dividing the numerator and denominator by the gcd value: Example:
    256 / 100 = (256/4) / (100/4) = 64/25
Example One percent is equal to one hundredth:
1% = 1/100
So in order to convert percent to fraction, divide the percent by 100% and reduce the fraction.
For example 56% is equal to 56/100 with gcd=4 is equal to 14/25:
56% = 56/100 = 14/25

How to calculate decimal to octal


step 1: divide decimal number by 8
step 2: write down the residual of division
step 3: if the result of division if 7 or less, write it to the left of residual you wrote in step 2, and there you go, you;ve got an octal represent. If the result is greater or equal to 8 then:
step 4: divide that result by 8
step 5: write the residual of that division to the left of the last one you wrote
step 6: from tis point everything is the same as from step 3.

Example: calculate octal represent of 123

123 / 8=15 , and residual is 3
15 >= 8, so the next thing you do is:
15 / 8 =1, and residual is 7
so far, we have 73
1<=7, so you write it to the left of 7, and there you go, 173 is octal represent of 123.

Hope this was helpful.
if you want to check your calculations, most calculator software has option to automatically calculate octal represents, i.e.

When I type 12!/5!7! I'm getting 2.01180672e10. My answer is suppose to be 792. Please help.


Somehow you're calculating 12!/(5!/7!).

Press 1 2 MATH left-arrow 4 / 5 MATH left-arrow 4 / 7 MATH left-arrow 4 ENTER to calculate the desired value. Alternatively, you can press 1 2 MATH left-arrow 3 5 ENTER or 1 2 MATH left-arrow 3 7 ENTER to calculate the same thing.

I can't find the universal power key or the universal root key on my TI-84 plus. Can someone tell me where it is?


The power key is marked ^ and is located just above the divide key. For example, to calculate 2 raised to the 7th power, press 2 ^ 7 ENTER

There is no key for the universal root. The operation is available in the MATH MATH menu. For example, to calculate the 7th root of 128, press 7 MATH 5 1 2 8 ENTER

I need the EXACT solution for -7 + square root of 61 divided by 2. I have a Ti-30XA calculator and I don't know how to do this.


It is unclear whether your equation is:

a: ((SQRT61) - 7) / 2
or
b: ((SQRT61) / 2) - 7

For a:
Type 61 SQRT.
Subtract 7.
Equals.
Divide by 2.
Equals. (Should be 0.4051248...)


For b:
Type 61 then SQRT.
Then divide by 2.
Equals.
Then subtract 7.
Equals. (Should be -3.094875...)

Good luck.

What is the answer to 10x minus 3x equals 20 plus 1 equals what


joshua,

X = 3 (answer)

Here are the solution steps:

10x minus 3x equals 20 plus 1

10X minus 3X is 7X (right?)
20 plus 1 is 21 (right?)
therefore:

7X = 21

now divide both sides of the equals sign by 7

7X divided by 7 equals 21 divided by 7

7X / 7 = 21/7

X = 3 (answer)
