Use law of cosines

BC^2 = AB^2 + CA^2 - 2 (AB)(CA) cos A      solve for cos A

Each 'hour' position is 30 degrees  (12 hours in full circle 360)

  Two less hours in the hand position would be 60 degrees difference...

Wrong

The area is 26.

The sum of the coordinates is 18.

By power of a point, CM = 5*sqrt(3).

The side length is $s = \frac{\sqrt{2}}{2}$

NO is   5 out of (5+2+1) = 5/8ths of 24      5/8 * 24 = 15 units

That is what I get too....I counted the wrong direction from 200....I should have counted UP.....after I saw your answer, I re-counted and got 218 also

Thanx!  Alan     ~EP

Possible number    5 * 4 * 3 * 2 * 1 = 120 numbers

  3/5 ths end in an odd number making the number an odd number    3/5 * 120 = ______

A short computer program gives 218 for the 100'th green coconut.

convert 2 inches to feet     2/12 = 1/6 ft    then    radius = 1/12 ft

Area * length = volume

pi (1/12)^2  *100 = pi 100/144 = 25/36 pi ft³  =~~  2 ft³     ( to nearest ft³ )

Educated guess:  179

Area sequence         pi (64 + 16 +4 + 1)      the common ratio is 1/4 as you can see

sum of an infinite sequence  

S = a1 / (1-r)

  64 pi / (1 - 1/4 ) = 85.33 pi  in²

Incorrect

What is this number?    0.30403...8

Do you mean that the number is repeating?    Is the number  0.3040 where the 3040 keeps repeating?   

And it is in base 8

If I have interpreted it correctly then

let  

10000x = 3040.30403040...   base 8

          x =       0.30403040...   base 8

 7777x = 3040   base 8

\(x=\frac{3040}{7777}\;\;base8\\ x=\frac{340}{1111}\;\;base8\\ \)

a= 340    and b=1111

2b = 2222

a   =   340

2b-a =   1662 (base 8)

You need to include brackets

There are 4 such integers.

n      n^2

4     16
6     36
14     196
16     256
 

There are 72 such numbers as follows:

139  148  157  166  175  184  193  229  238  247  256  265  274  283  292  319  328  337  346  355  364  373  382  391  409  418  427  436  445  454  463  472  481  490  508  517  526  535  544  553  562  571  580  607  616  625  634  643  652  661  670  706  715  724  733  742  751  760  805  814  823  832  841  850  899  904  913  922  931  940  989  998  Total =  72 such integers.

Thanks... but why centered 0,0?

I'm wrong again...

Here's a good video about the subject::::   https://www.youtube.com/watch?v=kHQ50pJXUnU

Since you have said this is a repeat you should have posted the address of the original post.

Can you find it and post it here?

Anyway, the answer will be the last digit which is the sum of the last digits.

4+4+ 4  etc

consider the series   

2,6,10,   .... 110

a=2  d=4   tn=110   find n

110=2+(n-1)*4

108/4=n-1

n=28

24*4=112

so the remainder will be 2

Note: I have not checked my answer.

I made an error...     x² + y² = 9  this is wrong!!!

x² + y² = 25

https://doubleroot.in/lessons/coordinate-geometry-basics/locus-equation-1/

x² + y² = 9
