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 .

There are 14 apples and 26 oranges in a picnic basket. What percentage of the fruit in the basket is oranges?
Answers
The percentage of oranges in the basket is 65%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of oranges = 26
Number of apples = 14
The percentage of oranges.
= 26/40 x 100
= 65%
Thus,
There are 65% of oranges.

Step-by-step explanation:
Answer:
-53/12 or 4 5/12 either works
Step-by-step explanation:
Let's turn the mixed fractions into improper fractions.
-7 2/3 = -23/3
-5 1/2 = -11/2
8 3/4 = 35/4
Now we need to find Least Common Denominator.
12 is the LCD because
3*4 = 12 is for -23/3
2*6 = 12 is for -11/2
4*3 = 12 is for 35/4
Now you will multiply the improper fractions by the 2nd number.
[tex]-\frac{23}{3}*(\frac{4}{4}) = -\frac{92}{12} \\\\-\frac{11}{2}*(\frac{6}{6}) = -\frac{66}{12} \\\\\frac{35}{4}*(\frac{3}{3}) = \frac{105}{12}[/tex]
Now that they have the same denominators just put the numerators in the equation.
-92 + -66 + 105 = -53
-53/12 or -4 5/12

So -3 2/7 = -23/7
2 2/3= 8/3
Second, make the denominators the same number
So multiply -23/7 by 3 and 8/3 by 7

Solution
First identify the input values. The input value is the first coordinate in an ordered pair. There are no restrictions, as the ordered pairs are simply listed. The domain is the set of the first coordinates of the ordered pairs.
D={2,3,4,5,6}
Next identify the output values. The output value is the second coordinate in an ordered pair. The range is the set of the second coordinates of the ordered pairs. Do not list the same output twice.
The second coordinate in an ordered pair is the output value. The range is the collection of the ordered pairs' second coordinates. Never list the same output more than once.
What is a domain?The domain of the function is defined as the set of all the possible values of the function. A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
Determine the input values first. The first coordinate in an ordered pair makes up the input value. Since the ordered pairs are just listed, there are no restrictions. The set of the ordered pairs' initial coordinates is known as the domain.
D={2,3,4,5,6}
Next, identify the output values. The output value is the second coordinate in an ordered pair. The range is the set of the second coordinates of the ordered pairs. Do not list the same output twice.
