(a) What resonant frequency would you expect from blowing across the top of an empty soda bottle that is 24 cm deep, if you assu

Kryger [21]

Answer:

a) 357.29 Hz

b) 535.9375 Hz

Step-by-step explanation:

v = Velocity of sound in air = 343 m/s

l = length = 24 cm

$l=\frac{1}{4}\lambda \\\Rightarrow \lambda=4l$

$f=\frac{v}{\lambda}\\\Rightarrow f=\frac{v}{4l}\\\Rightarrow f=\frac{343}{4\times 0.24}\\\Rightarrow f=357.29\ Hz$

∴ Resonant frequency is 357.29 Hz

b) Here one third is filled with soda

So, length becomes $l=24-\frac{24}{3}=16\ cm$

$f=\frac{v}{4l}\\\Rightarrow f=\frac{343}{4\times 0.16}\\\Rightarrow f=535.9375\ Hz$

∴ Resonant frequency is 535.9375 Hz

A local amusement park charges $21.50 per daily adult ticket and $14.75 per daily child's ticket. A group of 12 people paid $204

ivanzaharov [21]

Answer:

Step-by-step explanation:

Even though you didn't provide options from which to choose, you don't need them to figure out the system. We need an equation that involves the NUMBER of people and then we need an equation that involves the MONEY earned. Two different things here.

As for the number of people, we know that the number of adult tickets + the number of children = 12 people, so

x + y = 12.

That's the first equation. Now for the money:

21.50x + 14.75y = 204.00

That's your system.
