Answer:
decagon has total 1440° interior angles.
Explanation:
using the formula to find total interior angle: ( n -2 ) * 180
<em>where n is the number of sides</em>
<em>Here given the number of sides is 10</em>
<em>using the formula:</em>
( 10 - 2 ) * 180
1440°
Answer:
The correct option is B. two oxygen atoms
Step-by-step explanation:
The molecular formula for carbon dioxide is given by :

Here, the alphabet C stands for Carbon and the alphabet O stands for Oxygen.
And the prefixes of each of these words represents the number of atoms present of the corresponding element in one molecule of carbon dioxide.
So, The prefix of the first word that is C is 1
⇒ One molecule of carbon dioxide contains one atom of Carbon.
The prefix of the second word that is O is 2
⇒ One molecule of carbon dioxide contains 2 atoms of Oxygen.
Therefore, The correct option is B. two oxygen atoms
Let's call the number "n"
if we write in an equation what you said it's like this:
n*2+4-n-3=n+1.
first i will move all the "n"s to the left and all the numbers to the right
n*2-n-n=1+3-4
which is....
0=0
this means that for EVERY number, if you double it, add four, subtract three, you will get this number plus one. <span />
The first one is $240, and the second one is $235.20
