Here is the set up:
(1/4)/2 = (9/4)/y
Solve for y.
Answer:
4/7 or 4:7
Step-by-step explanation:
8/14 divided by 2= 4/7
Answer: <em>3. The correct option is: A) 3.57 decibels.</em>
<em>6. The correct option is: B)
</em>
Step-by-step explanation:
3. Sound intensity is cut to 44% of its original level. That means, if the original sound intensity was 100, then now sound intensity will be 44.
So,
and 
Using the formula
, we will get.....

<em>(Rounded to the nearest hundredth)</em>
So, the loudness would be reduced by 3.57 decibels.
6. Given expression is: 
First applying the property
, we will get.....

Now using the formula,
, we will get....

Thus, the answer as a single natural logarithm is 
Answer:
The length of one side is 13 feet.
Step-by-step explanation:
To start, a square is 4 sides that are equal in length. This means that when you have a problem like this, you need to set the equations equal to each other like:

In order to solve a problem like this, with the same variables on different sides, start by subtracting the smaller variable from both sides. In this case, you would be subtracting 2x from both sides, which would leave us with:

After that, you solve it like a normal one-step equation. Add 11 to both sides.
Now, divide both sides by 4 and you will know how much
is worth.

Now that we know how much
is worth, we can plug that into either of the equations given to us. It doesn't matter which since they are equal to each other.

That would give us 13.
