Answer:
tetrahedral
Step-by-step explanation:
According to the valence shell electron pair repulsion theory (VSEPR) the shape of a molecule is dependent on the number of electron pairs on the valence shell of the central atom in the molecule.
The predicted electron pair geometry may sometimes differ from the molecular geometry due to the presence of lone pairs and multiple bonds.
If we consider each nitrogen atom in N2 independently, we will notice that each nitrogen atom has four regions of electron density. Hence the electron pair geometry is tetrahedral.
Answer:
x = 3.75
Step-by-step explanation:
So, lets start with what we know.
Line = 180 degrees
Triangle = 180 degrees, a + b + c = 180
So, we can form the equations,
17x - 1 + <CDB = 180
-17x + 1 -17x + 1
<CDB = 181 - 17x
and
84 +7x + 5 + <CDB = 180
89 + 7x + <CDB = 180
-89 -89 + 7x
<CDB = 91 + 7x
Here, we are given 2 values of <CDB, but they must be the same, so let's substitute them into each other
181 - 17x = 91 + 7x
-91 +17x -91 +17x
90 = 24x
90 / 24 = 24x / 24
3.75 = x
x = 3.75
There, you have it, x is 3.75

Answer:
The slope would be 1/5
the y intercept is (0,2)
the mperpendicular is -5
Step-by-step explanation:
you have to use the y=mx+b formula
To multiply two fractions together, multiply the numerators of both fractions together and same goes for the denominators.
Simplify.
So, 1/3 is the answer.
Answer:
39=6t+3f+e
39=19f+1
5 touchdowns, 3 extra points, and 2 field goals.
Step-by-step explanation:
e=f+1
6t=15f
39= 6t +3f +e
^ ^ ^
39=(15f)+(3f)+(f+1) | e=f+1 | 6t=15f
39=19f+1 | e=2+1 | 6t=15(2)
38=19f | e=3 | 6t=30
f=2 | | t=5
