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
a)


∴ Resonant frequency is 357.29 Hz
b) Here one third is filled with soda
So, length becomes 

∴ Resonant frequency is 535.9375 Hz
Answer:
0.1
Step-by-step explanation:
To set this question up:
1/2 / 5
To solve this turn 5 into 5/1. Then multiply by the reciprocal. (1/5) 1/2 times 1/5 is 0.1
Answer:
In each muffin there are 1.53oz
Step-by-step explanation:
The first step is to get the weight of just one muffin. If the package contains six muffins we must divide the total weight by six.

The weight of just one muffin is 3oz.
Now, the problem says that blueberry high-fiber muffins contain 51 % dietary fiber by mass, which means that we must calculate the 51% of 3oz. We must take into account that 51% equals 51/100 which is 0.51. The equation would be:

Finally, in each muffin there are 1.53oz of fiber.
Answer:
The expression used to find the change in temperature per hour is Algebraic expression
Thus per hour; the temperature falls at the rate of
Step-by-step explanation:
A temperature falls from 0 to
in 
Which expression finds the change in temperature per hour.
From the above given information;
The initial temperature is 0
The final temperature is
The change in temperature is 


Thus;
-12.25 ° = 3.5 hours
To find the change in x° per hour; we have;
x° = 1 hour
The expression used to find the change in temperature per hour is Algebraic expression
From above if we cross multiply ; we have;
(- 12.25° × 1 hour) = (x° × 3.5 hour)
Divide both sides by 3.5 hours; we have:

x° = - 3.5
x° = 
Thus per hour; the temperature falls at the rate of

3
Step-by-step explanation:
Parallel lines have same slope.
