The decibel level of the sound of a monster truck is
Further explanation:
Decibel is defined as a unit which is used to measure the relative loudness or intensity of the sound.
In the question it is given that the intensity of the sound of a monster truck is watts per square inch.
The formula which is used to calculate the decibel level of a sound is as follows:
Here, represents the intensity of the sound of a monster truck and represents the threshold intensity of hearing at .
The value of the threshold intensity of hearing at is watts per square meter.
This implies that the valiue of is watts per square meter.
The intensity of the sound of a monster is given in unit of per square inch.
The relation between per square inch and per square meter is as follows:
So, the intensity of a monster truck is converted into per square meter as follows:
This implies that the value of is watts per square meter.
Now, substitute the value of and in the equation .
The approximated value of the above equation is as follows:
From the above calculation it is concluded that the decibel level of the sound of a monster truck is .

Answer:
39/100
39%
0.39
Step-by-step explanation:
All of these are equivalent to each other! Any number over 100 can easily be transferred to a percentage value, so 39/100 is also equivalent to 39%. Considering that it is also by the hundredths, 0.39 is also an answer choice due to the conversion from fraction to decimal form. I hope that this helped! <3

Which statement is true?
The Mississippi River in Iowa is at an elevation of 279 and Death Valley, in California is at an elevation of -282 feet. Which statement is true?
A |279| > |-282|
B |279| < |-282|
C 279 = 282
D 279 < -282
Answers
Answer:
B
Step-by-step explanation:
The symbol "|" means absolute value so for example |-12| is not equal to -12 it is equal to just 12.
A would be incorrect because |-282| is equal to 282 and 282 is greater than 279.
B would be correct because 279 is less than 282
C would be incorrect because 279 is not equal to 282, 279 is equal to 279.
D would be incorrect because -282 is not greater than 279

Step-by-step explanation:
First of all -2-5= -7
It isn't (A) because (A) is saying that the beginning temperature was a postive number, which it wasn't The beginning temperature is -2, which is negative. So we can cross that off.
It isn't (B) because (B) is saying that you start off with -2 and then it gets warmer, and temperature adds up onto it. When you do -2 +5, you get 3, which is not the answer.
So, the answer is c
Proof: It starts of with negative 2, which is the first temperature. Then, it says decreased by 5, which is what is happening. 5 is getting subtracted from -2
So, the answer is C
Answer:
C
Step-by-step explanation:
-2-5
the minus sign infront of the two has to stay with the two so we would have -2°C the options we would be left with are b and c but since it says subtract 5 that would be a decreases not an increase so it would be decrease 5°C

30.047 miles
30.407 miles
Answers
x= miles per day
your answer would be 3.047 miles
Answer:
3.047
Step-by-step explanation:
[tex]\frac{miles}{days} \\ \\\frac{15.235}{5} = \frac{?}{1} \\[/tex]
When solving equations you multiply the denominator of one of the fractions by the others numerator. Here the available numerator is 15.235 and the others denominator is 1. This means that we do 15.235 times 1, which is equal to 15.235. The next step is to divide by the remaining denominator or numerator. Here the remaining denominator is 5. This means that we divide 15.235 by 5 which is equal to 3.074.
