Sophia manages a landfill. She decides to measure the rate at which trash increases in volume to fill the landfill as the number of households served increases.
Answer:
[tex]\frac{m^3}{h}, \frac{cm^3}{h}, \frac{km^3}{h}[/tex]
Step-by-step explanation:
If you look at the objects thrown as garbage, it's a two- or three-dimensional item that takes up space and also has mass and this is a solid waste.
And the landfill that dumps such garbage is also three-dimensional.
Hence, the volume module, if the object inside is a solid, either would be
[tex]m^3,cm^4,Km^3[/tex]
As household numbers rise, landfill space increases.
So,
[tex]household\ number = Proportionality\times landfill\ space[/tex]
If H represents the number of household keeps, then it will be a sufficient unit for the purpose of Sophia that is
[tex]\frac{m^3}{h}, \frac{cm^3}{h}, \frac{km^3}{h}[/tex]

Which of the following is equal to the opposite of −45? −(−45) −45 −|−45| −|45|
Answer:
-(-45) and -|45|
Step-by-step explanation:
Opposite of a number can also me termed the conjugate of such number. For example, the conjugate (opposite) of a is -a.
Also any value in the modulus sign can either be a negative or positive value. For example |a| can be +a or -a.
According to the question, we are to find the numbers that are equivalent to opposite of -45 i.e which of them are conjugate of -45.
To do this, we are to select the values in the options that will return +45.
Let's look at each option.
For -(-45):
Since the product of two negative sign will give a positive(+), then -(-45) = +45 and hence the value is opposite of -45
For -45:
-45 is a negative value and can never be positive since 45 is not inside a modulus sign. Hence, -45 is not equal to opposite of -45.
For −|−45|, |-45| can only return a positive value since -45 is already in a modulus sign. What the modulus sign will do is convert it to positive value i.e |-45| = 45. Hence -|-45| ≈ -(45) which is not also equivalent to the opposite of-45.
For -|45|:
The value inside modules will return both +45 and -45, hence it can be written as -|45| = -(-45) = +45. This shows that -|45| is also equivalent to the opposite of -45.
Answer:
-(-45) and -|45|

Answers:
R = -3S = -3T = -9For each row, you're adding the values of 'a' and 'b'. The first row has 1+2 = 3.
When adding two negatives, add the positive versions of each number, then make the result negative. So -1 + (-2) can be thought of as 1+2 = 3, then you make everything negative.
When adding a negative to a positive, you'll subtract the positive version of each number. The final result is positive if the larger absolute value is positive, or otherwise it's negative. We have -4+1 that can be thought of as 4-1 = 3, but since the '4' is larger and it is negative, this means -4+1 = -3.
Hector is flying a kite. He has let out 86 feet
of string and is holding it 4 feet off the
ground. If the string is at an angle of
elevation of 42°15’30”, how high is the kite?
Answer:
Hector's kite is 61.84 feet from the ground.
Step-by-step explanation:
The angle of elevation of the kite is 42°15’30” when converted to decimals, it is [tex]42.258333^{0}[/tex] ≅ [tex]42.26^{0}[/tex]
Let the height of the kite to the horizontal of angle of elevation be represented as x. Applying the trigonometric function to the sketch of Hector's kite,
Sin θ = [tex]\frac{opposite}{hypotenus}[/tex]
Sin [tex]42.26^{0}[/tex] = [tex]\frac{x}{86}[/tex]
⇒ x = 86 x Sin [tex]42.26^{0}[/tex]
= 86 x 0.6725
= 57.835
x ≅ 57.84 feet
The height of Hector's kite from the ground = x + 4
= 57.84 + 4
= 61.84 feet

Answer:
2. Kayla's opportunity cost to go to the movie is $9.50
4. Tara's total cost of attending the movie is $50.5
Step-by-step explanation:
Complete question below:
Tara earns $8.50 an hour (after taxes) at the pizza place. She is scheduled to work four hours this afternoon. However, her friend Kayla called and asked her if she wants to go to the movie. A ticket to the movie costs $9.50. In addition, she always spends about $7 on snacks.
Which of the following statement are true? Select all that apply.
1. Tara's opportunity cost if she goes to work instead of the movie is $34.
2. Kayla's opportunity cost to go to the movie is $9.50.
3. There is no opportunity cost for Tara to go to the movie.
4. Tara's total cost of attending the movie is $50.5
5. Tara's opportunity cost if she goes to the movie instead of working is $34
Solution
Tara earns $8.50 per hour
She is scheduled to work for 4 hours
Total earnings=$8.50 × 4
=$34
Tara's opportunity cost of attending the movie instead of working is $34
Since, a ticket cost $9.50
And she always spend about $7 on snacks
Tara's total cost of going to the movies = opportunity cost of attending the movie + cost of tickets + cost of snacks
=$34 + $9.50 + $7
=$50.5
Opportunity cost refers to the cost of satisfying a want at the expense of another want. It can also be called REAL COST or TRUE COST.
Therefore,
2. Kayla's opportunity cost to go to the movie is $9.50
4. Tara's total cost of attending the movie is $50.5

Graph the line with slope -3 passing through the point (5,1) .
Answer:
we know that,
y-y1=m(x-x1)
or, y-1=-3(x-5)
or, y-1=15-3x
or 3x+y-16=0 is the required equation
The graph of the line with slope -3 passing through the point (5,1) is attached.
The equation of the line in the slope-intercept form is y = -3x + 16.
The equation of the line in the standard form is 3x + y = 16.
What is the equation of a line?The equation of a line is the representation of a line on a coordinate plane (x-y plane), which shows the relation between x and y, for every point on the particular line.
The standard form of a line is ax + by = c, where x and y are variables and a, b, and c are constants.
The slope-intercept form of a line is y = mx + b, where x and y are variables, m is the slope of the line, and b is the y-intercept of the line.
What is the one-point formula of a straight line?The equation of a line passing through the point (x₁, y₁), having a slope m, is represented by the one-point formula: y - y₁ = m(x - x₁).
How do we solve the given question?We are asked to graph a line with a slope = -3, passing through the point (5, 1).
We use the one-point formula to determine the equation of this line, with slope m = -3, (x₁, y₁) = (5, 1).
Substituting these values in the equation y - y₁ = m(x - x₁), we get
y - 1 = -3(x - 5)
or, y = -3x + 15 + 1
or, y = -3x + 16.
or, 3x + y = 16
The equation of the line in the slope-intercept form is y = -3x + 16.
The equation of the line in the standard form is 3x + y = 16.
To graph this line we plot the points (5, 1) (as it is given that it passes through this point) and (0, 16) (as the y-intercept is at 16, so the line passes through the point (0, 16)). We join these points by a line and extend this line on both sides to get the required line.

Consider the following set of data: 3, 6, 8, 15, 21, 22, 23 Define what is meant by “ measures of variation”. What is the interquartile range of data? What is the mean absolute deviation of the data?
Answer:
Below.
Step-by-step explanation:
A measure of variation is an estimate of the spread of the numbers.
For example the set of numbers 1 2 3 19 78 has a greater measure of variation than the set 1 2 3 5 9.
The interquartile range and the mean absolute deviation are measures of variation.
3 6 8 15 21 22 23
The median of the data is the middle number 15..
The lower quartile is 6 and the higher quartile is 22
The interquartile range is 22 - 6 = 16.
The mean absolute deviation (M.A.D.) is calculated as follows:
Mean = (3+6+8+15+21+22+23) / 7 = 98/7
= 14.
List the absolute differences from the mean
14 - 3 = 11
14-6 = 8
15-14 = 1
21-14= 7
22-14 = 8
23-14 = 9 ( all these have to be positive)
The sum of the differences is 11+8+1+7+8+9 = 44
So the MAD = 44/7 = 6.3 to nearest tenth.

What are data analysis and interpretation?The process of attributing meaning to the acquired data and deciding the conclusions, relevance, and consequences of the results is known as data analysis and interpretation.
How do we solve the given question?We are given a data set, representing the time taken by Amy to run each mile while running 8 miles, nearest to 1/4th of a minute.
We are asked to find how long did it take Amy to run her slowest and fastest mile combined.
Analyzing the data, we can say that her slowest mile will be the one for which she took the maximum time, that is, 9 2/4 minutes. Whereas her fastest mile will be the one with the minimum time, that is, 8 3/4 minutes.
We are asked to tell the combined time for her slowest and the fastest mile, so we add times for both, to get
Combined time = 9 2/4 + 8 3/4
or, Combined time = 38/4 + 35/4
or, Combined time = 73/4
or, Combined time = 18 1/4.

Can someone help me find the domain and range of this graph?
Answer:
Domain: (-5, 6]
Range: [-3, 6]
Step-by-step explanation:
Domain is all x-values that can be inputted into function f(x).
Range is all the y-values outputted by function f(x) when we plug in x.
We see that our x-values span from -5 to 6. Since -5 is a open dot, we cannot input -5. Therefore, we have:
Domain: (-5, 6]
Parenthesis on -5 shows that it is not included and bracket on 6 shows it is included.
We see that our y-values span from -3 to 6. Since both points are closed dots, we can include both. Therefore, we have:
Range: [-3, 6]
Brackets on both numbers signify that both values are included in the graph.
