Answer:

Step-by-step explanation:
we know that
To find out how much solution the scientist used for the experiment multiply 3/4 by 1/6
so

simplify

I do not know this one but the first garden is 24 and the second one is 576.
A perfect fifth above a note has a frequency ratio of 3 to 2.
Therefore, we can set the proportion:
164.81 : x = 2 : 3
which gives:
x = <span>164.81 </span>× 3 ÷ 2
= 247.21
Hence, the perfect fifth above E₃ will have a frequency of 247.21Hz which corresponds to a B₃.
