yes, i forgot to put it in my equation

JUST SO YOU KNOW I HOPE YOU ARE NOT IN UNI!!!!

GO BACK TO PRESCHOOL!!!!!!!!!!!!

Nothing will cancel; is there a division sign between them?

used as an informal way of saying “hello”

(8x + 7)(4x - 6)                     Use FOIL:

= 8x·4x  +  8x·-6  +  7·4x  +  7·-6

= 32x² - 48x + 28x - 42

= 32x² - 20x - 42

If this is to be one payment after 6 years using simple interest, use the simple interest formula:  I = Prt

I = interest          P = principal (amount borrowed)         r = rate (as a decimal)        t = time

--->     I  =  (9000)(.0495)(6)  =  $2673.00

So, the amount owed is $9000.00 +  $2673.00  =  $11,673.00

If you want a monthly payment amount, you will need to repost and ask for that ...

(r^8t^6 - 7)^2  =  (r^8t^6 - 7)(r^8t^6 - 7)

Use FOIL:      r^8t^6·r^8t^6  -  7·r^8t^6  -  7·r^8t^6  +  49

             =     r^16t^12 - 14r^8t^6 + 49

What is the question?

ln(0.1) = -2.30258...

If  a = 6  and  b = 9, then  b - a  =  9 - 6  =  3  (positive)

If  a = 6  and  b = 3, then  b - a  =  3 - 6  =  -3  (negative).

Thus, the statement is not true for all possibilities.

Check by using the Pythagorean Theorem:     c²  =  a² + b²

C is the largest value:  c  =  12.3     Therefore,  a  =  6.2     and     b  =  8.1  

        (or a  =  8.1  and  b  =  6.2;  it doesn't make any difference)

Check this:  does  12.3²  =  6.2² + 8.1² ?

12.3²  =  151.29

6.2² + 8.1²  =  38.44 + 65.61  =  104.05

Since these values aren't equal, it is not a right triangle.

The tenth is the first number to the right of the decimal point (the 0).

So, the answer will be either      1.0     or     1.1

If the digit after the 0 is 4 or smaller, round down  -->  choose 1.0

If the digit after the 0 is 5 or more, round up  -->  choose 1.1

Since it is a 3, round down, and choose 1.0 for your answer.

I was just making sure.

Yes, everyone knows that

20%  = 0.20

of  =  times

20 percent of 100 cm

0.20 x 100  =  20 cm

If a 16 foot tall giraffe casts an 8 foot tall shadow, then, by the same ratio, a 6 foot tall stump casts a 3 foot tall shadow. 

16/8  =  6/x

Cross multiply:  16·x  =  6·8          --->         16x  =  48         --->         x  =  3

Paul Erdös (1913-1996) wrote, and co-authored, a great many math papers. He was noted for the quality of his work and that he collaborated with more than 500 other mathematicians.

Erdös has Erdös number 0.

Any person who co-authored a paper with Paul Erdös has Erdös number 1.

Any person (who does not have an Erdös number smaller than 2) who co-authored a paper with a person who has Erdös number 1 has Erdös number 2.

Any person (who does not have an Erdös number smaller than 3) who co-authored a paper with a person who has Erdös number 2 has Erdös number 3.

Etc. 

Person C has Erdös number 1.

Person B has Erdös number 2.

Person C has Erdös number 3.

That is what the calculator is for, kinda what the website is...

What does that have to do with anything about math?

1 + 78h  =  157

Subtract 1 from both sides:

      78h  =  156

Divide both sides by 78:

          h  =  2
