Answer:

9.3 in

Step-by-step explanation:

Perimeter = add up the sides

12.3 + 5.4 + x = 27

17.7 + x = 27

x = 27-17.7

x = 9.3

Using the formula do you sound level and disciples are use the intensity of the sound you're measuring. Set an alarm to normal c
Stella [2.4K]

Answer:

65.1 decibels

Step-by-step explanation:

Given

I = 3.2 * 10^{-6} --- intensity

Required

Determine the sound level

This is calculated using:

B = 10\log(\frac{I}{I_o})

Where:

I_o = 1 * 10^{-12}

So, we have:

B = 10\log(\frac{3.2 * 10^{-6}}{1 * 10^{-12}})

Apply law of indices

B = 10\log(\frac{3.2 * 10^{-6+12}}{1})

B = 10\log(3.2 * 10^{6})

Using a calculator, we have:

B = 10*6.51

B = 65.1

Rei is barricading a door to stop a horde of zombies. She stacks boxes of books on a table in front of the door. Each box weighs
Alinara [238K]

Answer: The answer is \textup{W}=70+30x.


Step-by-step explanation: Given that Rei is barricading a door to stop a horde of zombies by satcking boxes of books on a table in front of the door.

The weight of each box is 30 kilograms and the weight of the table with 8 boxes on the top is 310 kilograms.

So, if 'g' denotes the weight of the table alone, then we have

\textup{g}+8\times 30=310\\\\\Rightarrow \textup{g}+240=310\\\\\Rightarrow \textup{g}=310-240\\\\\Rightarrow \textup{g}=70.

Therefore, the weight of the table without boxes is 70 kilograms.

Now, if 'W' is the total weight of the barricade, then it can be written as a function of 'x', the number of boxes Rei stacks on the table. The expression is as follows -

\textup{total weight of the barricade}=\textup{weight of the table alone}+30\times \textup{number of boxes}.

Thus, the required function is

\textup{W}=70+30x.
