I am working simultaneous equations use matrices. My solution appears in fraction format when I need them to be in decimal form. Using it to do mesh analysis in circuits

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

It appears you had a little too much "party time," as you are on the wrong site for academic results

A. The equation of a circle is (x-a)^2 + (y-b)^2 = r^2, with (a,b) being the centre of the circle and r being the radius.

Good luck,

Use the words: decimal part, not decimal fractin

**Any number whose decimal part is periodic (has a recurring pattern that repeats indefinitely) is equivalent to a rational number, IS a rational number**

0.345 345 345 ... =345/999=115/333

In the following screen captures, discard the last digit if it does not belong to a period. It is the effect of rounding up of the calculator

**Period is 345**

**Period is 1**

Period is**09**

Period is** 79**

In general, if you have a decimal part of the form 0.d_1 d_2 d_3....d_n d_1 d_2 d_3 ...d_n ... where d_1 is the first digit of the period, d_2 is the 2nd digit of the period, ..., d_n is the n-th digit (and the last one) of the period, then the fraction representation of

0.**d_1d_2...d_n** d_1d_2... d_n ...=(**d_1d_2...d_n**)/(99...9) where the number of 9's in the denominator is equal to the number of digits in the period.

Once the fraction is found, one should reduce it to its simplest form.

Bot are numbers that are written in two different representations. To compare them safely you must convert them to the same representation.

0.08=8/100 or 8%

Now compare 8 % and 6%

Another way to do it is to convert 6% to its decimal representation then compare it to 0.08

6%=6/100=0.06

Since we have fractions let us just compare them. When comparing fractions, we first convert them to the same denominator (here it is 100). The greater one is the one with the greater numerator: 8 is greater than 6.

**Conclusion: No, 0.08 is not less than 6%**

0.08=8/100 or 8%

Now compare 8 % and 6%

Another way to do it is to convert 6% to its decimal representation then compare it to 0.08

x=.25061047

or

x= 1/(4*cos(4))

or

x= 1/(4*cos(4))

With algebra you are learning problem solving-that is the process of problem solving using rules and equations. The best way to learn it is to shut out all distraction and work at it. If there is something you don't understand you may have to go back to the beginning and learn all the principals and rules that you don't understand- Algebra can be a very hard subject but it can be concord with persistence.

The circumference of a circle is C=2 * pi * r or C= pi * d.

What do we know? C=47.1 and pi.

What are we trying to calculate? d

Put what we know in the equation and solve for d.

47.1 = pi * d

To isolate d, we have to divide both sides by pi.

47.1

------ = d

pi

I get 14.99' or approximately 15' as the diameter.

Good luck,

Paul
