ANSWER:
50% increase
The percent of change of 30 increased to 45 is a 50% increase.
STEP-BY-STEP EXPLANATION:
% of change = [ ( New amount - original amount ) / original amount ] × 100%
Let % of change = x
x = [ ( 45 - 30 ) / 30 ] × 100%
x = ( 15 / 30 ) × 100%
x = ( 1 / 2 ) × 100%
x = 0.5 × 100%
x = 50%

Answer:
So, the time interval between successive compression from the source is 0.002 seconds.
Step-by-step explanation:
Given that,
Frequency of the tone, f = 500 Hz
It is sitting at a distance of 450 m from the source of sound, d = 450 m
Let t is the time interval between successive compression from the source. We know that the relation between the frequency and the time period is :
<h3>So, the time interval between successive compression from the source is 0.002 seconds.</h3>
Answer,
<em>(26/2) * 3</em>
<em>= 39</em>
Explanation,
<u><em>26 cookies is only 2/3 of 3/3. So, we divide 26 by 2 to see how many cookies are in 1/3. We then can find out that when you make 1/3 of the cookies there are 13. Since that is only 1/3 and we want to find out 3/3. We multiply 13 by 3 and get 39 which is all the cookies she planned to make.</em></u>
