Question What is the decibel level of the noise from a motorcycle with intensity 10-2 watts per square inch? Use a logarithmic model to solve. Provide your answer below: 100 dB
The decibel level of the noise from a motorcycle with intensity 10⁻² watts per square inch (W/in²) is equal to 50 dB.
What is sound intensity?In Science, sound intensity can be defined as a measure of the power of a sound wave per unit area. This ultimately implies that, sound intensity is a quantity that is typically be used for measuring the energy of sound and its unit of measurement is Watts per square meter (W/m²) or .
How to calculate the sound intensity level?Mathematically, sound intensity level or decibel level can be calculated by using this formula:
[tex]\beta = 10 log(\frac{I}{I_{ref}} )[/tex]
Note: The reference value of sound intensity is equal to 1.0 × 10⁻¹² watts per square inch (W/in²).
Since the intensity of the noise from this motorcycle is 10⁻² W/in², the decibel level (in dB) would be calculated as follows:
Decibel level, β = 10 × log(10⁻²/10⁻¹²)
Decibel level, β = 10 × log(10¹⁰)
Decibel level, β = 10 × 10

Solve each system by elimination: 4x-7y=10 3x+2y=-7
Using the elimination method, the solution to the system of equations is as follows:
x = 19 / 13 and y = - 74 / 13
How to solve system of equation?System of equations can be solved using different methods such as the elimination method, substitution method, and graphical method.
Let's use the elimination method to solve the system of equations as follows:
The elimination method is the process of eliminating one of the variables in the system of equations using the addition or subtraction methods in conjunction with the multiplication or division of coefficients of the variables.
Therefore,
4x - 7y = 10
3x + 2y = -7
multiply equation(ii) by 3.5
4x - 7y = 10
10.5x - 7y = 24.5
subtract equation(i) from equation(ii)
6.5x = 14.5
x = 14.5 / 6.5
x = 145 / 65
x = 19 / 13
Let's find y
3(19 / 13) + 2y = -7
57 / 13 + 2y = -7
2y = - 7 - 57 / 13
2y = -91 - 57 / 13
2y = - 148 / 13

A basketball coach recorded how many shots each of the 30 players at tryouts made in a set of 6
attempts. Here are the results:
The median would lie in the mean of the 15th and the 16th position.
What is median?The middle value in a sorted, ascending or descending list of numbers is known as the median, and it has the potential to describe a data collection more accurately than the average does. It reflects the midway of the data since it is the point above and below which half (50%) of the observed data falls.
The mean (average), mode, and standard deviation are some other descriptive statistics that are frequently contrasted with the median.
Given, the total number of basketball players present (n) = 30
Total number of attempts made = 6
Since there are even number of players present, 30, the location of the median would be n/2 and n/2 + 1 positions.
For 30, the positions would be
= 30/2 and 30/2 + 1
= 15 and 16th position

Ruby and her children went into a movie theater and she bought $42 worth of bags of popcorn and drinks. Each bag of popcorn costs $6 and each drink costs $4. She bought a total of 8 bags of popcorn and drinks altogether. Determine the number of bags of popcorn and the number of drinks that Ruby bought.
Answer:
5 bags of popcorn
3 drinks
Step-by-step explanation:
Let's set up a system of equations!
Let p equal the number of bags of popcorn and d be the number of drinks.
We know Ruby bought 8 total, so we know [tex]p + d = 8[/tex]. We also know that she spent $42 total, so we can multiply their respective costs by the number to set up another equation: [tex]6p+4d=42[/tex]. We have our system of equations now!
Let's use substitution to solve this. From the first equation, subtracting p from both sides gives us that [tex]d=8-p[/tex]. We can plug this into our second equation to solve for p. Plugging in this for d gives us [tex]6p+4(8-p)=42[/tex]. Multiplying through and then combining like terms results in [tex]32+2p=42[/tex]. We then can subtract 32 from both sides and divide us by 2, which gives us that p = 5.
Now we solve for d! We can plug in the value of p into the equation [tex]p+d=8[/tex], to get that d = 3. To check our work, we can plug these values into the other equation, which gives us [tex]6*5 + 4*3 = 42[/tex]. This is true, so our values are correct!

4x2-20x+3=0
4x2-20x=-3
A(x2-5x)=-3
What is the value of A?
Answer:
A = 4
Step-by-step explanation:
4x2-20x=-3 and A(x2-5x)=-3
Hence:
4x2-20x = A(x2-5x)
4x^2 - 20x = A(x^2 - 5x)
Divide both sides by (x^2 - 5x) to isolate A:
(4x^2 - 20x)/(x^2 - 5x) = (x^2 - 5x) * A/(x^2 - 5x)
A = (4x^2 - 20x)/(x^2 - 5x)
A = (4x(x - 5)) / (x(x - 5)) ==> factor each polynomial
A = (4x) / (x) * (x - 5)/(x - 5)
A = (4x) / (x) * 1 ==> (x-5)/(x-5) = 1
A = (4x) / (x)
A = 4x/x ==> simplify
A = 4

The value of the shortest of the three sides of the triangle is 13 cm.
How to find the length of a triangle?A triangle is a polygon with threes sides. The perimeter of a triangle is the sum of the whole three sides.
The lengths of the three sides of a triangle (in centimetres) are consecutive odd integers. The perimeter is 45 cm.
The shortest side of the three sides can be calculated as follows:
let
the first side = x
second side = x + 2
third side = x + 4
Hence,
perimeter = x + x + 2 + x + 4
45 = 3x + 6
45 - 6 = 3x
3x = 39
divide both sides by 3
x = 39 / 3

A spherical ball for a machine was made with a radius of 2 centimeters.
If the ball has a mass of 278.1 grams, which material was used to make the ball?
Copper-8.3 g/cm³
Brass -8.6 g/cm³ Iron - 7.8 g/cm³
The mass of the ball is 278.1 g, the material used to make the ball must be brass which having density of 8.6 g/cm³.
How to find mass of the ball ?To determine the material used to make the ball, we need to first calculate the volume of the ball.
The volume of a sphere with radius r is given by:
V = (4/3) * π * r^3
Plugging in the given values, we get:
V = (4/3) * π * (2 cm)^3
= (4/3) * π * 8 cm^3
= (4/3) * 8π cm^3
= 32π cm^3
We can then use the density of each material (given in g/cm³) to calculate the mass of the ball if it were made of that material:
Copper: 8.3 g/cm³ * 32π cm³ = 266.4 g
Brass: 8.6 g/cm³ * 32π cm³ = 275.2 g
Iron: 7.8 g/cm³ * 32π cm³ = 250.4 g
Since the mass of the ball is 278.1 g, the material used to make the ball must be brass.

A large tree casts a shadow that is 51 feet long. A 6-foot-tall person standing next to the tree casts a shadow that is 4.5 feet long. How tall is the tree?
Answer:
68 feet tall
Step-by-step explanation:
Imagine the shadows for both the tree and the person are set up like right triangles. The length of their shadows are the bases of the triangles, while the actual heights of the tree and person are the heights of the triangle. We can set up proportions since "height of the person" divided by " their shadow's length" should equal "height of tree" divided by "tree shadow length".
Set up a proportion of the person's high height relative to their shadow's length (which is 6/4.5). Set this equation equal to the tree's proportion (which is x/51).
Solve for x.
[tex]\frac{6}{4.5} = \frac{x}{51}\\Isolate x by multiply 51 to both sides\\\\(306/4.5)=x\\68=x[/tex]
The proportion is solved and the height of the tree is A = 68 feet
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
Now , we can set up the following proportion:
Height of tree / length of tree's shadow = height of person / length of person's shadow
On simplifying , we get
A / 51 = 6 / 4.5
Now we can solve for A by cross-multiplying and simplifying:
A = 51 x 6 / 4.5
A = 68 feet
Therefore, the tree is 68 feet tall

For the first case:
If 2 movies are streamed, the cost is $14 per month
So the cost = number of movies * cost per movie
y = 2*x
14 = 2x
For the second case:
If 6 movies are streamed, the cost is $20 per month
So the cost = number of movies * cost per movie
