Answer:
698.46 Hz
Step-by-step explanation:
A note an octave higher than another note is double the amount of frequency.
In this example, the note is 349.23 Hz. Doubled, this is 698.46 Hz. Therefore, the final answer is the first option, 698.46 Hz

Answer:
<u>Option C. 9</u>
Step-by-step explanation:
The question is as following:
In triangle ABC, D is the midpoint of line AB and E is the midpoint of line BC. If AC= 3x-15 and DE= 6, what is the value of x?
==================================================
See the attached figure which represents the problem.
As shown:
D is the midpoint of line AB ⇒ AD = DB
E is the midpoint of line BC ⇒ BE = EC
Apply The Mid-segment theorem which states that the mid-segment connecting the midpoints of two sides of a triangle is parallel to the third side of the triangle, and the length of this mid-segment is half the length of the third side.
So, DE = 0.5 AC
Given: Ac = 3x-15 and DE =6
∴ 6 = 0.5 (3x - 15)
solve for x
Multiply both sides by 2
12 = 3x - 15
3x = 12 + 15 = 27
x = 27/3 = 9
So, the value of x is 9
<u>The answer is option C. 9</u>
The value of x if that's what you mean is 2 because first you add 3 from both sides and your new equation should be 2x>14-5×, then you add 5x from both sides and your new equation should be 7x>14. After that you divide 14 by 7 and your final answer will be x=2 or 2
14x+28
Not 100% sure if this is right. I done this and it’s how I passed. I added all my X’s together and then added the rest of Them. It worked for me but it might not for you.
