How many triangles are formed by the diagonals in a 21 sided polygon?
The number of triangles formed by the diagonals of a 21 sided polygon is C(21,3) = 21x20x19/3x2x1 = 1,330.
What is 23 c?
23C
What is 23 c equals -18?
41
What is the difference between 15 degrees Celsius and -8 degrees Celsius?
23
What is the answer to c over 15 equals 21 over 9?
c/15 = 21/9 → c/15 x 15 = 21/9 x 15 → c = (7x3)/(3x3) x (3x5) → c = 7 x 5 = 35
C plus -2 equals 21?
C+ (-2)= 21= 21+2= 23+ (-2)= 21 23+ (-2)= 21 is the same as 23- 2= 21

How many atoms are in 9.7x10-3 mole C?
There are approximately 5.8x10^21 atoms in 9.7x10^-3 moles of carbon. This is calculated by multiplying Avogadro's number (6.022x10^23 atoms/mol) by the number of moles of carbon.
The 2 am temperatures for five days during the week were 26 c 24 c 19 c 21 c and 25 c what was the average daily temperature for 2 am?
Add the (5) temperatures and divide by the number of days (5). 26 + 24 + + 19 + 21 + 25 = 115 divided by 5 is the average, 23 degrees Celcius.

What is the difference of -23 degree Celsius and 64 degree Celsius?
87 degrees C.
How many atoms are in each elemental sample 8.4 and times10 and minus3 mol C?
To find the number of atoms in 8.4 x 10^-3 moles of carbon (C), you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms/mol. Multiply the amount in moles by Avogadro's number: 8.4 x 10^-3 mol C × 6.022 x 10^23 atoms/mol ≈ 5.05 x 10^21 atoms. Therefore, there are approximately 5.05 x 10^21 atoms in the sample.
