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.

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.
