Answer:
B: 2800 hydrogen atoms
C: 6760 hydrogen atoms
D: y=amount of oxygen atoms*2
Step-by-step explanation:
B: We know the formula for water is H2O. SO that means that there is 2 hydrogen atoms and 1 oxygen atom. So there is 2 times the amount of hydrogen atoms so we can do 1400*2=2800, So there is 2800 hydrogen atoms in the water.
C: Same thing as B. 3380*2=6760
D: y=amount of oxygen atoms*2. Because there is one oxygen atom and two hydrogen atoms so 1*2=2.
9=3^2
3^(2x)=(3^2)^(3x-4)
3^(2x)=3^(6x-8)
2x=6x-8
0=4x-8
8=4x
2=x

<h3>Option D</h3>
The value of y in the parallelogram is 34°
Step-by-step explanation:
Adjacent angles of the Parallelogram are supplementary
So,
(78° + 3y°) = 180°
78° + 3y° = 180°
Subtract 78° each side we get,
78° - 78° + 3y° = 180° - 78°
3y° = 102°
Now, Divide both side by 3 we get,
3y°/3 = 102°/3
y = 34°
Thus, The value of y in the parallelogram is 34°

Answer:
The answer is
<h2>20 units</h2>
Step-by-step explanation:
The distance between two points can be found by using the formula
<h3>

</h3>
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(5,9) and (-7,-7)
The distance between them is
<h3>

</h3>
We have the final answer as
<h3>20 units</h3>
Hope this helps you
