We also need to know how far we are from the tree to calculate this.....

To convert a fraction to a decimal, divide the numerator by the denominator. For example: One-fourth = One divided by four = 0.25

Divide 2500 by 80 and ignore the remainder (it's hard to buy a fraction of a cat!).

2500 ÷ 80  =  31 cats and a remainder of $20.00.

5x/x^2-x-6 + 7/7^2+4x+4

$$\\(5x/x^2)-x-6 + (7/7^2)+4x+4\\
5/x-x-6 + 1/7+4x+4\\
5/x+3x-2 + 1/7\\
5/x+3x-(1 + 6/7)\\
5/x+3x-13/7\\$$

You can simplify the subtraction of logs by tuning the problem into a division problem.

log₃(x) - log₃(4)  =  log₃(x/4)

log₃(x/4) - log₃(12)  =  log₃(x /4 ÷ 12)  =  log₃(x/48)

Since 405 ends in 5, it is divisible by 5 --

405  =  5 x 81

Since 81 = 9 x  9 --

405  =  5 x 9 x 9

Since 9 = 3 x 3 --

405  =  5 x 3 x 3 x 3 x 3

Since those factors can't be reduced:

405  =  3⁴ x 5

Just type this into the on-site calculator  ....

factor(405)

.7853982×4^2×3.48×16=699.695548416 round up would be 700.

It is best to think of normal numbers first and see what happens

judy has 80 peices   Wendy has 10 peices less.   That is 70 peicse to Wendy

if Judy gives Wendy 5 peices than they will both have 75 peices

5=10/2

Mmmm...I just tried it......seems to work fine....

Yes of course you are correct Chris.    I must have been suffering a major CDD recurrence.   

This site might help you?

A combination counts sets......a permutation also considers order within a set.

Thus....

A combination would consider the sets {1, 2} and {2, 1} to be the same thing....one set.

A permutation would count them as two different sets.......

I think you might be confused...

"Supplementary" angles are two angles which sum to 180 degrees.

Thus.........a supplementary angle could be the sum of two 90 degree angles.......but it might also be the sum of an acute angle (less than 90 degrees) and an obtuse angle (greater than 90 degrees)...thus a 30 degree angle and a 150 degree angle would sum to 180 degrees.

After considering this problem again, I believe that my answer  is correct - 16.

Looking at Melody's answers, she states that AABB and BBAA are palindromes.

But after doing a little research, I discovered that this isn't quite correct. A palindromic number or numeral palindrome is a number that remains the same when its digits are reversed. See the description, here....

divide the top fraction by the bottom then multiply the result 100 and read off the answer

$$\left({\frac{{\mathtt{\pi}}}{{\mathtt{180}}}}\right){\mathtt{\,\times\,}}\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{tan}}^{\!\!\mathtt{-1}}{\left(-{\mathtt{1}}\right)}{\mathtt{\,\small\textbf+\,}}{\mathtt{3.14}} = {\mathtt{2.354\: \!601\: \!836\: \!602\: \!551\: \!7}}$$

$$\left({\frac{{\mathtt{\pi}}}{{\mathtt{180}}}}\right){\mathtt{\,\times\,}}\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{tan}}^{\!\!\mathtt{-1}}{\left(-{\mathtt{1}}\right)}{\mathtt{\,\small\textbf+\,}}{\mathtt{\pi}} = {\mathtt{2.356\: \!194\: \!490\: \!192\: \!344\: \!9}}$$

i used this calc and i get   2.356

--------------------------

now without a calc

atan(-1)+pi   =  -pi/4 + pi = 3pi/4

$${\frac{{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{\pi}}}{{\mathtt{4}}}} = {\mathtt{2.356\: \!194\: \!490\: \!192\: \!344\: \!9}}$$

i know the only reason i say that is i live with my grandparents so i want to respect his privacy and if i join he'll notice and i don't wat him to go all fe fi foe on me so...by the way i saw on a post that you lived in sydney how is it there?

i love cheese! but i'm lactose intolerent

$$\\4500(1+0.032)^n>5000\\\\

$${\frac{{log}_{10}\left({\frac{{\mathtt{10}}}{{\mathtt{9}}}}\right)}{{log}_{10}\left({\mathtt{1.032}}\right)}} = {\mathtt{3.344\: \!919\: \!817\: \!058\: \!767\: \!9}}$$

The side opposite the 30° angle (the short side) is 1/2 the hypotenuse.

The side opposite the 60° can be found by multiplying the short side by √3.

Since they are all independent choices, multiply the possible choices together:  4 x 9 x 3 x 10  =  1080 possible combinations.

(5x²y) / (2x)

The x in the denominator cancels one of the x's in the numerator:  5xy/2

Find the amount of discount:  $125.00 - $90.00  =  $35.00

Divide by the original price:  $35.00 / $125.00  =  0.28

Turn into a percentage:  0.28  =  28%
