What is the rate of change of the total cost in dollars with respect to
the number of additional minutes?
Answers
Answer:
C
Step-by-step explanation:
Since the rate is linear, we can subtract a larger amount of minutes by a smaller one and a larger cost by a smaller one.
For example:
20 - 15 = 5
3.40 - 3.05 = 0.35
Since you want to find the amount it takes per minute, you divide the 5 by 5 to make it one minute. You also divide the 0.35 by 5 in which you get 7.

Answer: So, according to this prediction, a book with 19 chapters would have approximately 950 pages. However, keep in mind that this is just a prediction based on the trend line, and there may be some variability in the actual number of pages for a book with 19 chapters.
Step-by-step explanation:
Unfortunately, I cannot see the scatter plot you are referring to. However, I can explain how to use a trend line to predict the number of pages in a book with 19 chapters.
A trend line is a line that represents the general direction or tendency of the data in a scatter plot. To use a trend line to predict the number of pages in a book with 19 chapters, you would first need to determine the equation of the trend line.
This equation usually takes the form y = mx + b, where y is the dependent variable (in this case, the total number of pages), x is the independent variable (in this case, the number of chapters), m is the slope of the line, and b is the y-intercept (the value of y when x is 0).
Once you have the equation of the trend line, you can plug in the value x = 19 and solve for y to get the predicted number of pages in a book with 19 chapters.
For example, if the equation of the trend line is y = 50x + 200, then the predicted number of pages for a book with 19 chapters would be:
y = 50(19) + 200
y = 950
So, according to this prediction, a book with 19 chapters would have approximately 950 pages. However, keep in mind that this is just a prediction based on the trend line, and there may be some variability in the actual number of pages for a book with 19 chapters.

Find the ordered pair (s,t) that satisfies the system
s/2+5/t=3
3t-6s=9
Answers
The ordered pair (s,t) that satisfies the system are (1/2,4) and (1,5).
We can use the second equation to solve for one of the variables in terms of the other. Let's solve for t:
3t - 6s = 9
3t = 6s + 9
t = (2s + 3)
Now we can substitute this expression for t into the first equation and solve for s:
s/2 + 5/t = 3
s/2 + 5/(2s + 3) = 3
Multiplying both sides by the denominator (2s + 3) gives:
s(2s + 3)/2 + 5 = 3(2s + 3)
Simplifying and collecting like terms yields:
2s^2 + 3s + 10 = 6s + 9
2s^2 - 3s + 1 = 0
This quadratic equation can be factored as:
(2s - 1)(s - 1) = 0
So s = 1/2 or s = 1.
Now we can substitute these values for s into the equation we derived for t:
If s=1/2 then t=2(1/2)+3=4
If s=1 then t=2(1)+3=5
Therefore, the ordered pairs that satisfy the system are (1/2,4) and (1,5).

Step-by-step explanation:
1st we can find x by sum theory which is the sum of all side equal to 180° .
x + 90° + 76° = 180 °
x + 166° = 180°
x= 180° - 166°
x = 14° ... So the unknown angle is 14°
and we also can solve hypotenus t and adjecent r by using sin amd cos respectively by angle 76° .
sin(76) = 12/t
sin(76) t = 12 ....... criss cross it
t = 12 / sin(76) ....... divided both side by sin(76)
t = 12.367 ~ 12.4 ....... result
And
cos(76) = r / 12.4
r = cos(76) × 12.4 .......criss cross

Answers
George's new store will have a profit of $5,400 in its fifth month in business.
We are given two functions: r(x) = x^2 + 5x + 14 for revenue, and c(x) = x^2 - 4x + 5 for expenses. We are asked to find the meaning of (r - c)(5).
Step 1: Subtract c(x) from r(x) to find (r - c)(x)
(r - c)(x) = r(x) - c(x) = (x^2 + 5x + 14) - (x^2 - 4x + 5)
Step 2: Simplify the expression
(r - c)(x) = x^2 + 5x + 14 - x^2 + 4x - 5 = 9x + 9
Step 3: Evaluate (r - c)(5)
(r - c)(5) = 9(5) + 9 = 45 + 9 = 54
The value (r - c)(5) = 54 represents the difference between the revenue and expenses in the store's 5th month of operation, measured in hundreds of dollars. In other words, George's new store will have a profit of $5,400 in its fifth month in business.

A table tennis ball has a radius of 0. 04m. Estimate how many table tennis balls you could fit into the coin building! [search up what it is—]
( Width: 20m | height: 110m )
- How did you calculate your estimate?
- Explain how accurate you think your prediction is?
( Show Work. )
Answers
Number of balls ≈ [tex]1.03 * 10^9[/tex]
To calculate how many table tennis balls can fit into the coin building, we need to first figure out the volume of the building and the volume of the table tennis ball.
Then, we can divide the volume of the building by the volume of the ball to get an estimate of the number of balls that can fit inside.
The volume of a table tennis ball can be calculated using the formula for the volume of a sphere, which is:
V = (4/3)πr³
where V is the volume, π is pi (approximately 3.14), and r is the radius of the ball. In this case, the radius is given as 0.04m, so we can plug that in and get:
V = (4/3) x 3.14 x 0.04³
[tex]V =2.14 * 10^{-5} m^3[/tex]
Next, we need to find the volume of the coin building. The building has a width of 20m and a height of 110m, but we don't know its depth.
Let's assume that the building is a rectangular prism with a depth of 10m. Then, we can calculate its volume using the formula:
V = l x w x h
where l is the length, w is the width, and h is the height. Plugging in the given values, we get:
V = 20 x 10 x 110
V = 22000 m³
Now, we can divide the volume of the building by the volume of the ball to get an estimate of how many balls can fit inside:
Number of balls ≈ [tex]V_building / V_ball[/tex]
Number of balls ≈ 22000 / 2.14 x [tex]10^-5[/tex]
Number of balls ≈ [tex]1.03 * 10^9[/tex]
So we can estimate that approximately 1.03 billion table tennis balls can fit into the coin building.
As for the accuracy of this prediction, it's important to keep in mind that we made some assumptions and estimations in our calculations.
For example, we assumed that the building is a rectangular prism with a depth of 10m, which may not be completely accurate.
Additionally, we rounded some of our values and used approximations for pi.
Therefore, our estimate should be considered as a rough approximation rather than an exact calculation. Nonetheless, it gives us an idea of the scale of the building and how many objects it can hold.

Supplementary Angles of Given Angles
Supplementary angles are pairs of angles that add up to 180 degrees. To find the supplementary angle of each given angle, we simply subtract the angle from 180 degrees.
Therefore, the supplementary angles of the given angles are:
The supplementary angle of 26 degrees is 154 degrees (180 - 26 = 154).
The supplementary angle of 44 degrees is 136 degrees (180 - 44 = 136).
The supplementary angle of 45 degrees is 135 degrees (180 - 45 = 135).
The supplementary angle of 136 degrees is 44 degrees (180 - 136 = 44).
The supplementary angle of 135 degrees is 45 degrees (180 - 135 = 45).
The supplementary angle of 154 degrees is 26 degrees (180 - 154 = 26).

The area of ΔRST, to the nearest square inch is,
Area = 29,17,735.54 square inches
We have,
In ΔRST, s = 990 inches, ∠S=8° and ∠T=60°.
Apply sine rule formula,
sin S / s = sin T / t
sin 8° / 990 = sin 60° / t
0.14 / 990 = 0.87 / t
0.14t = 990 x 0.87
0.14t = 861.3
t = 6,152 inches
Here, ∠R = 180° - (8 + 60)°
∠R = 180 - 68
∠R = 112°
sin S / s = sin R / r
sin 8° / 990 = sin 112° / r
0.14 / 990 = 0.92 / r
0.14r = 0.92 x 990
0.14r = 910.8
r = 910.8 / 0.14
r = 6505 inches
We use the formula
Heron's formula = √s(s - a)(s - b)(s - c)
Where s = a + b + c/2
Solving for s
s = 990 + 6505 + 6,152 /2
s = 6823.5

Answers
Answer:
The equation provided is y = 1200x + 7000, where y is the yearly income and x is the number of years of education.
To determine how much 1 year of education adds to a person's yearly income, we need to find the change in y when x increases by 1.
Let's plug in x and x+1 into the equation to find the corresponding yearly incomes:
When x = 1, y = 1200(1) + 7000 = $8200
When x = 2, y = 1200(2) + 7000 = $9400
The difference between these two yearly incomes is:
9400 - 8200 = $1200
Therefore, 1 year of education adds $1200 to a person's yearly income according to the model.

The probability that a randomly selected house with 2 bathrooms has 3 is: 0.8.
So, the fourth option is correct.
We have given that,
The two-way table shows the number of houses on the market in the Castillos’ price range.
A 6-column table has 4 rows.
The first column has entries 1 bathroom, 2 bathrooms and 3 bathrooms, in total.
The second column is labeled 1 bedroom with entries 67, 0, 0, 67.
The third column is labeled 2 bedrooms with entries 21, 6, 18, 45.
We are only considering the houses that have 2 bathrooms.
There are a total of 30 of these houses.
Out of these 30, 24 have 3 bedrooms.
What is the formula for probability?
The probability of an event can only be between 0 and 1 and can also be written as a percentage.
This makes the probability 24/30, which is 0.8.
Therefore, the probability that a randomly selected house with 2 bathrooms has 3 is: 0.8.
So, the fourth option is correct.

Harold, Rhonda, and Brad added water to beakers in science class. The line plot shows the amount of water, in cups, that they added to each of 14 beakers.
Answers
In the given line plot, the data represents the amount of water, in cups, that Harold, Rhonda, and Brad added to each of 14 beakers in their science class.
A line plot is a way to represent data that involves marking a number line for each data point and placing an “X” above the number that represents the value of that data point.
The line plot shows that most of the beakers were filled with either 1 or 2 cups of water. Specifically, there are 5 beakers with 1 cup of water and 6 beakers with 2 cups of water. There are also 2 beakers with 3 cups of water and 1 beaker with 4 cups of water.
The line plot provides a visual representation of the data that allows the viewer to quickly understand the distribution of the data. By seeing that most of the data is clustered around 1 and 2 cups of water, one can infer that the students were likely instructed to add a specific amount of water to each beaker. However, the presence of a few outliers, such as the beaker with 4 cups of water, suggests that some of the students may have made errors in their measurements or not followed the instructions closely.
Overall, the line plot provides a quick and easy way to visualize the distribution of the data and identify any outliers or patterns in the data. It is a useful tool for representing small to medium-sized datasets and is commonly used in education, research, and data analysis.

Based on the study, what was the population density, in people per square mile, of the United States in 20102010? Round your answer to the nearest tenth.
Answers
The population density is 87.4, under the condition that a study report shows that in 2010 the population of the United States was counted to be 308,745,538 people and the land area is approximately 3,531,905 square miles.
Now to evaluate the population density of the United States in 2010, here we have to use the principles of division
Population density = Population / Land area
Staging the values from the study
Population density = 308,745,538 / 3,531,905
The evaluated Population density = 87.4 people per square mile
Then, the United State's population density in 2010 was evaluated as 87.4 people per square mile.

If a photo measures 4 inches by 6 inches is places in a frame that measure 2 inches wide all around what percent of the fear is the photo itsel
Answers
The photo takes up 30% of the framed area.
To calculate the percentage of the frame that is taken up by the photo, we first need to calculate the dimensions of the framed photo. If the photo measures 4 inches by 6 inches, the dimensions of the framed photo will be 8 inches by 10 inches (adding 2 inches to each side).
To calculate the area of the frame, we need to subtract the area of the photo from the area of the framed photo. The area of the photo is 4 inches x 6 inches = 24 square inches. The area of the framed photo is 8 inches x 10 inches = 80 square inches. So, the area of the frame is 80 square inches - 24 square inches = 56 square inches.
To calculate the percentage of the frame that is taken up by the photo, we divide the area of the photo by the area of the framed photo and multiply by 100.
24 square inches / 80 square inches x 100 = 30%
Therefore, the photo takes up 30% of the framed area.
