Use this formula to calculate the loan payment:                                                                                                           PMT=PV. R.{[1 + R]^N/ [1 + R]^N - 1}

PMT =21,000 x 0.045/12{[1 + 0.045/12]^(5*12) / [1 + 0.045/12]^(5*12) - 1}

PMT = 78.75{[1.00375]^60 / [1.00375]^60 - 1}

PMT =78.75 x               4.9714718.....

PMT = $391.50 - The monthly payment for 60 months, or 5 years.

In mathematics, a rational number is any number that can be expressed as the quotient or fraction . The set of all rational numbers, often referred to as "the rationals", the field of rationals or the field of rational numbers is usually denoted by a boldface Q

20/100 of 35$ : 0.2*35=7 so 7/2=3.5 

So 3.5$ you and 3.5$ your friend

i always start with 2

obvi that will not work here

then try 3

that will work

3*3227

now try 2 again, nope

3? nope

4? nope

5? nope

6? nope

7? yes

3*7*461

now on to 2 again, nope

3? no

4? no

5? no

6? no

7? no

maybe that is it then

is 461 a prime number

seems so

final answer 3*7*461

20/100 of 750 = 0.2*750=150

So is 20% OFF :750-150=600$

the sales price is 600$

This is the quadratic formula:
 

\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)

Let's try it with an equation to see it in action:

\(x^2+6x-3=0\)

First, find a,b, and c and take note of those values! Remember, a typical quadratic can be written in the form of

\(ax^2+bx+c=0\). a equals the coefficient of the x^2 term., b equals the coefficient of the x-term, and c equals the constant.

a=1, b=6, c=-3

Now, plug those values into the quadratic formula and solve for x:

\(x = {-6\pm \sqrt{6^2-4(1)(-3)} \over 2(1)}\)

\(x = {-6 \pm \sqrt{36+12)} \over 2}\)

\(x = {-6 \pm \sqrt{48} \over 2}\)

\(x = {-6\pm 4\sqrt{3} \over 2}\)

\(x = -3\pm 2\sqrt{3}\)

Now, try this example on your own:

\(-3x^2-x+14=0\)

i do not think you can put infinity into a calculator. 

best to just imagine it.

[32 + (7 • 6 – 22)] – [30 ÷ (4 + 1)]

32+42-22-(30/5)

32+42-22-6

46!!!

6+2x-5 

1+2x

\(5[3-(7-8)]\) simplifies to 20

An equation must have an equal sign, which \(5[3-(7-8)]\) lacks, so \(5[3-(7-8)]\) is an expression—not an equation.

Let's evaluate this expression step by step:

pretty sure the answer is 20

5[3-(-1)]=

5[4]=

150 pounds

He is a fat guy

The increase is given by

(4/3) pi [ 9^3 - 3^3 ]  ≈  2940.53  cu ft

2.2%  = .022

So

.022 * 44000 = 968

Sorry MG....that's not quite correct....

Assuming that any digit can be repeated.....

We have 10 ways to choose a value in each position.....so the total number of possible combinations =

(10) (10) (10)   =  10^3   = 1000

So....the chances that you guess the correct combination one one try =  1 / 1000  = .001  = .1%

Well, there are only 27 possibillities, so, hmm... maybe a 

3.7037037037 percentage?(703703703703703 repeating) 

Once again, please correct me if I'm wrong.

Exactly correct, MG.....!!!!

Let N be the number we're looking for

95  = .76N     divide both sides by .76

95/.76  = N   =   125

Arya is 3 years older than Cindi, and Kim is double Cindi's age. Lenny is 5 years older than Kim. Lenny is 17 years old. How old is Arya?

Let   Cindi's age  = C

Kim's age =  2C

Lenny's age = 2C + 5   = 17

Solving the last equation we have

2C + 5  = 17       subtract 5 from both sides

2C  =  12             divide both sides by 2

C  =  6   = Cindi's age.....and Arya  is three years older  = 9

If Lenny is 5 years older than Kim, and Lenny is 17, then Kim is 12, Cindi is 6, anf Arya is 9.

Assuming that  we can write  1 as 01, 2 as 02...etc.   and there are " n " two digit numbers

The number of combinations  is  given by C (n , 5)

For instance.....choosing 5  numbers from 50  gives  C (50,5)  =

2,118,760  combinations (different possibilities)

What do you need help with?

You are g*****n right.

That is what I think the answer is. Correct me if I'm wrong.
