Answer:
Step-by-step explanation:
S = second; F = flying time.
Since it can flap its wings 30 times, each second, we have already found our answer. The relationship between flying time (Wing flaps) and seconds is 30. In other words, it beats it's wings 30 times each second. Which is what the question asks.
Now we just have to write the equation:
This is because the seconds are <u>dependent</u> on the flap of wings, so s would be the y value.

Answer:
The table a not represent a proportional relationship between the two quantities
The table b represent a proportional relationship between the two quantities
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
<u><em>Verify each table</em></u>
<em>Table a</em>
Let
A ----> the independent variable or input value
B ----> the dependent variable or output value
the value of k will be
For A=35, B=92 --->
For A=23, B=80 --->
the values of k are different
therefore
There is no proportional relationship between the two quantities
<em>Table b</em>
Let
C ----> the independent variable or input value
D ----> the dependent variable or output value
the value of k will be
For C=20, D=8 --->
For C=12.5, D=5 --->
the values of k are equal
therefore
There is a proportional relationship between the two quantities
The linear equation is equal to
