1. AB = 15, BC = 14, AC = 10
2. AC = 20, AB = 10, BC = 15
Answer:
1. ∠B, ∠A, ∠C2. ∠C, ∠A, ∠B
Step-by-step explanation:
We know smaller side is opposite to smaller angle and the larger side is opposite to larger angle.
Considering this we have the following1. AB = 15, BC = 14, AC = 10
Put in ascending order:
AC < BC < ABSo the opposite angles are:
B < A < C----------------------------------------------------------------------
2. AC = 20, AB = 10, BC = 15
Put in ascending order:
AB < BC < ACSo the opposite angles are:

When you flip a coin, there are only two possible outcomes, heads (H) or tail (T).
If you consider the coin to be fair, then both outcomes have the exact same probability which can be calculated as the number of favorable outcomes divided by the total number of outcomes.
For the event "flip a coin" the probability of obtaining tail is:
[tex]\begin{gathered} P(T)=\frac{nº\text{favorable outcomes}}{total\text{ outcomes}} \\ P(T)=\frac{1}{2} \end{gathered}[/tex]The experiment consists on flipping the coin 8 times:
The coin is flipped 8 times, so the number of trials of the experiment is fixed (n=8).
Each trial has only two possible outcomes "Head"(failure) or "Tail" (success)
The probability of the result being tail is the same for each time the coin is flipped, this represents the probability of success of the experiment (p=0.5).
Each trial of the experiment (flipping the coin) is independent.
This experiment meets the binomial criteria, which means that it is a binomial experiment.
To calculate the probability you can apply the formula for the binomial probability:
[tex]P(X)=\frac{n!}{(n-X)!X!}\cdot(p)^X\cdot(q)^{n-X}[/tex]Where
n is the number of trials
X is the number of successes
p is the probability of success
q is the probability of failure and is complementary to p
For this experiment:
The number of trials is n=8
The number of successes is X=7
The probability of success is p=0.5
The probability of success is q=1-p=1-0.5=0.5
Use these values to calculate the probability of obtaining 7 tails:
[tex]\begin{gathered} P(X=7)=\frac{8!}{(8-7)!7!}\cdot(0.5)^7\cdot(0.5)^{(8-7)} \\ P(X=7)=\frac{8!}{1!\cdot7!}\cdot(0.5)^7\cdot(0.5)^1 \\ P(X=7)=\frac{40320}{1\cdot5040}\cdot\frac{1}{128}\cdot\frac{1}{2} \\ P(X=7)=8\cdot\frac{1}{128}\cdot\frac{1}{2} \\ P(X=7)=\frac{1}{32}\cong0.03125 \end{gathered}[/tex]The probability of getting 7 tails when flipping the coin 8 times is
P(X=7)= 0.03125

Let:
t = time spent as tutor
w = time spent walking dogs
Angel's parents want him to work for no more than 18 hours per week, so:

slope of 1/3 and passing through the point (3,2)
To determine the equation of the line that has slope m=1/3 and passes through the point (3,2) you have to use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]Where
m is the slope of the line
(x₁,y₁) are the coordinates of one point of the line
Replace the formula above with the known information about the line:
[tex]y-2=\frac{1}{3}(x-3)[/tex]Next is to write the equation in slope-intercept form, which means that you have to leave the y term alone on the left side of the equation and all other terms have to be on the right side.
-First, distribute the multiplication on the parentheses term:
[tex]\begin{gathered} y-2=\frac{1}{3}\cdot3-\frac{1}{3}\cdot3 \\ y-2=\frac{1}{3}x-1 \end{gathered}[/tex]-Second, pass "-2" to the right side of the equation by applying the opposite operation, "+2", to both sides of the equal sign:
[tex]\begin{gathered} y-2+2=\frac{1}{3}x-1+2 \\ y=\frac{1}{3}x+1 \end{gathered}[/tex]So, the equation of the line with slope 1/3 that passes through the point (3,2), expressed in slope-intercept form is:
[tex]y=\frac{1}{3}x+1[/tex]b -6(46 - 2) = 150A) 4-6 B) -5C) 9 D) (3)
To solve this equation, we need to follow the next steps:
1. Apply the distributive property:
[tex]b-6\cdot4b+6\cdot2=150\Rightarrow b-24b+12=150[/tex]2. Add the like terms, and subtract 12 to both sides of the equation:
[tex]-23b+12=150\Rightarrow-23b=150-12[/tex]3. Divide both sides of the equation by -23 (to isolate b):
[tex]\frac{-23}{-23}b=\frac{150-12}{-23}\Rightarrow b=\frac{138}{-23}\Rightarrow b=-6[/tex]Then, the answer to this equation is {-6} (option A).

Inverse VariationThe variable y is inversely proportional to x if there is a nonzero constant, k, such that y=k/x.The number k is called the constant of variation or the constant of proportionality.Now, suppose that y is inversely proportional to x. If y is 2 when x is 7, we can find the constant of proportionality by first solving for k and then rewriting the equation to create an inverse variation equation.Start by substituting the values for y and x in to the standard equation and solve for k:2=k/714=ky=14/xPart AUse the equation we just found to determine the value of y when x = 21. Part BFind the value of x when y = 28. Part CLet’s look at a real-world example using inverse variation.In physics, Boyle’s law states that if the temperature is constant, then the pressure, P, of a gas is inversely proportional to the volume, V, of the gas. If the pressure of the gas in a cylinder is equal to 250 kilopascals when the volume of the container is 1.7 cubic meters, then determine the constant of proportionality for this situation. Show your work. Part DUse the constant of proportionality from part C to write an inverse variation equation to model this situation. Part EUsing the equation from part D, determine what the pressure would be in the container if the size of the container were to increase to 3.2 cubic meters. Part FWhat would the approximate volume need to be if you wanted the pressure to be 150 kilopascals? Part GReturning to the situation from part C, assume that the container was stored in a cooler room. Now, as the temperature of a gas increases, the pressure of the gas increases. Similarly, if the temperature of the gas decreases, the pressure of the gas decreases.So, assuming the container was placed in a cooler room, you know that the temperature of the gas has decreased by an unknown amount. Write an inequality to model this new situation. Part HUse the inequality from part G to write an inequality that represents the possible pressure of the gas if it is placed in a 3 cubic meter container. Give your answer in the form P < #. Part IYour answer from part H includes an infinite number of possibilities. However, in terms of this situation, some of the possible values are extraneous solutions. These are solutions that do not work given the situation. Rewrite your answer to remove any extraneous solutions and explain your answer.
Part A)
According to the text, the equation that relates x and y is:
[tex]y=\frac{14}{x}[/tex]Substitute x=21 to find the value of y when x=21:
[tex]y=\frac{14}{21}[/tex]Simplify the expression:
[tex]\frac{14}{21}=\frac{7\cdot2}{7\cdot3}=\frac{2}{3}[/tex]Therefore, the value of y when x=21 is:
[tex]\frac{2}{3}[/tex]Part B)
To find the value of x when y=28, substitute y=28 and solve for x:
[tex]\begin{gathered} y=\frac{14}{x} \\ \Rightarrow28=\frac{14}{x} \\ \Rightarrow28x=14 \\ \Rightarrow x=\frac{14}{28} \\ \therefore x=\frac{1}{2} \end{gathered}[/tex]Therefore, the value of x when y=28 is:
[tex]\frac{1}{2}[/tex]Part C)
Since the pressure P is inversely proportional to the volume V, then:
[tex]P=\frac{k}{V}[/tex]Solve for k and substitute P=250kPa and V=1.7m^2 to find the constant of proportionality:
[tex]\begin{gathered} \Rightarrow k=PV \\ =(250\text{kPa})(1.7m^3) \\ =425\text{kPa}\cdot m^3 \end{gathered}[/tex]Therefore, the constant of proportionality for this situation is:
[tex]425\text{ kPa}\cdot m^3[/tex]Part D)
Substitute the value of k into the equation that shows the inverse relation between P and V:
[tex]\begin{gathered} P=\frac{k}{V} \\ \Rightarrow P=\frac{425\text{ kPa}\cdot m^3}{V} \end{gathered}[/tex]Therefore, the inverse variation equation model for this situation, is:
[tex]P=\frac{425\text{ kPa}\cdot m^3}{V}[/tex]Part E)
Substitute V=3.2m^3 to find the pressure under those conditions:
[tex]\begin{gathered} P=\frac{425\text{ kPa}\cdot m^3}{3.2m^3} \\ =132.8\text{kPa} \end{gathered}[/tex]Therefore, the pressure would be:
[tex]132.8\text{kPa}[/tex]Part F)
Isolate V from the equation and substitute P=150kPa:
[tex]\begin{gathered} V=\frac{425\text{ kPa}\cdot m^3}{P} \\ =\frac{425\text{ kPa}\cdot m^3}{150\text{ kPa}} \\ =2.83m^3 \end{gathered}[/tex]Therefore, the approximate volume would have to be equal to:
[tex]2.83m^3[/tex]Part G)
Since the temperature has decreased, the pressure must be lower according to the description provided in the text. Then, an inequality to model this situation would be:
[tex]P<\frac{k}{V}[/tex]Part H)
Substitute the value of k and V=3m^3:
[tex]\begin{gathered} P<\frac{425\text{ kPa}\cdot m^3}{3m^3} \\ \Rightarrow P<141.7\text{ kPa}^{} \end{gathered}[/tex]Part I)
Mathematically, all numbers under 141.7 satisfy the inequality from part H. Nevertheless, negative pressures do not have a physical meaning under the context of the Ideal Gas Law. Therefore, we must include the condition that P is greater than 0:
[tex]0-20x - 10y = 2010x + 5y = -10

The answer is the option CI have no idea how to do this but I have to graph and show work step by step. and graph the answer.
Here, we want to graph the given inequality
To do this, we need to get the intercepts of the normal line with the inequality replaced by an equality sign
Thus, we have;
[tex]y\text{ = }\frac{2}{3}x-1[/tex]Generally, we have the equation of a linear graph as;
[tex]y\text{ = mx + b}[/tex]where m represents the slope and b represents the y-intercept
With respect to this question, -1 is y-intercept of the line
Thus, the point of the y-intercept is (0,-1)
Now, we proceed to get the x-intercept.
To do this, we simply substitute the value 0 for y
We have;
[tex]\begin{gathered} 0\text{ = }\frac{2}{3}x\text{ - 1} \\ \\ \frac{2x}{3}\text{ = 1} \\ \\ 2x\text{ =3 } \\ \\ x\text{ = }\frac{3}{2} \\ \\ x\text{ = 1.5} \end{gathered}[/tex]The x-intercept here is thus the point (1.5,0)
Normally, to plot the graph of the line, we simply connect the two intercepts with a straight line
In the case of this inequality too, we are going to join the two points, but this time with dots and not straight lines
And also, since the inequality is greater than, we are simply going to shade the side above the dotted line
Kindly note that if there was an inequality sign, wherein, we have greater than or equal to, we are going to join with a thick line and shade
Let us check what we have in the plot below;

How would I solve this equation by rewriting it as a proportion?
To rewrite the given expression as a proportion multiply the 1/2 by a fraction that makes it have the same denominator as 1/2x (that fraction is x/x):
[tex]\begin{gathered} \frac{1}{2}*\frac{x}{x}+\frac{1}{2x}=\frac{x^2-7x+10}{4x} \\ \\ \frac{x}{2x}+\frac{1}{2x}=\frac{x^2-7x+10}{4x} \end{gathered}[/tex]Sum the fractions in the left of the equal:
[tex]\frac{x+1}{2x}=\frac{x^2-7x+10}{4x}[/tex]Then, the correct answer is third option
