Answer:
2/3
Step-by-step explanation:
First find what fraction of caffeine is hydrogen, 1 - 3/6 - 2/6 - 1/6 = H meaning hydrogen = 0/6 or 0.
Next add O + N + H which is 3/6 + 1/6 + 0/6 which is 2/3.
Answer:
12
Step-by-step explanation:
The difference of the two coordinates is ...
23 -(-10) = 33
The desired coordinate is 2/3 of that length from J, so is ...
J + (2/3)·33 = J +22 = -10 +22 = 12
The desired coordinate is 12.
Answer:
Step-by-step explanation:
<u>Use the Pythagorean theorem:</u>
<u>Verify this for each line:</u>
1.
- 28² + 45² = 53²
- 2809 = 2809
- Yes
2.
- 33² + 56² = 64²
- 4225 ≠ 4096
- No
3.
- 36² + 77² = 85²
- 7225 = 7225
- Yes
Answer:
The coefficient of squared term is 1/9
Step-by-step explanation:
The vertex of parabola is (2.-3)
We know the vertex form of a standard parabola
Plugging values of h and k, h= 2, k = -3
Now, x=5, y=-2
Thus, the coefficient of squared term is 1/9
