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 .

Sam spent $1.08 to make 18 copies at office max.At that rate how much will he pay to make 40 copies?
Answer:
$2.40
Step-by-step explanation:
If we know it is $1.08 to make 18 copies. We can do the math to find the rate of 1 copy. This would be by doing 1.08/18=0.06. So, it costs $0.06 to make 1 copy. Now, multiply that by 40 copies 0.06x40=2.40. The cost of 40 copies is $2.40.

3.Solve: 12 = -4h + 7 +11h
Which of the following would be an appropriate first step to take in solving for "h"?
Group of answer choices
adding 7 to both sides
adding 12 to both sides
combining (-4h) and (11h)
multiplying both side by 4
Answer:
$3.21
Step-by-step explanation:
Answer:
1: $3.21.
2: 50x+120=300
3: h=5/7/ first step would be to adding 7 to both sides.
Step-by-step explanation:
for the 3rd:
you're combining like terms so you have to subtract 7 from both sides you gotta subtract 12-7 so that gives you 5=7h+7-7 and the subtract the 7-7, and that will give you 0 so you have 5=7h left.divide both sides by the same terms (7), so you'll have 5/7 and 7h/7 so 7/7=0 so you drop that and just have the h. now switch sides with the virable and the fraction you still have (5/7)you now have h=5/7.Coach Hayes goes to a sporting goods store to purchase mouth guards for his team.
