The prediction about the waves if they were to crash into each other is that The resulting wave would travel at 4.2 hertz.
<h3>What is the wave about?</h3>
Note that:
Constructive interference of the waves is one that leads to an increase in amplitude or frequency of any kind of waves.
Hence:
F' = 3 Hz + 1.2 Hz
= 4.2 Hz
Destructive interference of the waves is one that lowers the amplitude or frequency of waves and as such:
F' = 3 Hz - 1.2Hz = 1.8 Hz
The prediction about the waves if they were to crash into each other is that The resulting wave would travel at 4.2 hertz.

Answer: Chapter 3: Bravery.
Explanation: Sal begins the story with her first moments in Lewiston. She overhears Margaret pleading with her father to tell Sal how they met, but Sal rudely refuses to hear the story. Sal marches glumly through their new house, situated only a few blocks from Margaret's, complaining about its size.
Answer:
Each ticket is $43.20
Explanation:
If there are five family members, and the meals are $.6.50 each, we will multiply $6.50 by 5.
$6.50 × 5= $32.5
Now we subtract the meals from the total of $248.50.
$248.50 - $32.5= $216
All five tickets cost $216, now we divide this by 5 since five tickets were bought.
= $43. 2
Each ticket was $43.20
Let's double-check:
$32.5 + $43.20(5)= $32.5 + $216= $248.50
