Sondra Anderson was looking at a winter coat that regularly sells for $179.99. On the rack was a sign that read 25% off all winter coats. What will the sale price be of the coat that Sondra wants to buy?
Answers
Given:
The regular price of the coat = $179.99

P = 2L + 2W for W. 2. 2x + 3y = -10 for y.
Answers
EXPLANATION
Given the equations:
1. P = 2L + 2W for W. (Subtracting 2L to both sides)
P - 2L = 2l + 2W - 2l (Dividing both sides by 2)
P/2 -2L/2 = W (Simplifying and switching)
W = P/2 - L
2. 2x + 3y = -10 for y. (Subtracting 2x to both sides)
2x - 2x + 3y = -10 -2x (Simplifying)
3y = -2x - 10 (Dividing both sides by 3)
y = -2x/3 - 10/3

Given the system of equations:

Let's plot both equations on a graph. The point where both lines meet.
• Equation 1:
Let's plot using 3 points.
Substitute random values of x and solve for y.
We have:
[tex]\begin{gathered} x=-4;\text{ y = }\frac{1}{2}(-4)+2=-2+2=0 \\ \\ x=0;y=\frac{1}{2}(0)+2=0+2=2 \\ \\ x=4;y=\frac{1}{2}(4)+2=2+2=4 \end{gathered}[/tex]For equation 1, we have the points:
(x, y) ==> (-4, 0), (0, 2), (4, 4)
Plot the points and connect the points with a straight line.
• Equation 2:
Let's create 3 points:
[tex]\begin{gathered} x=-2;y=\frac{1}{2}(-2)+1=-1+1=0 \\ \\ x=0;y=\frac{1}{2}(0)+1=0+1=1 \\ \\ x=2;y=\frac{1}{2}(2)+1=1+1=2 \end{gathered}[/tex]FOr equation 2, we have the points:
(x, y) ==> (-2, 0), (0, 1), (2, 2)
Now, plot the points and connect using a straight line.
We have the graph of both equations below:
From the graph, we can see that both lines do not meet at any point.
They are parallel lines,
Since they will not meet at any point, there is NO SOLUTION.

Oh no! You have just discovered Superhero C is actually a villain! He plans toactivate an underwater volcano that is 50 miles away. Superhero A is goingto try to stop him.Suppose getting to the underwater volcano requires a combination ofrunning, flying, and swimming.Using the rates from Table 1, make a plan for how far each Superheroshould run, fly, and swim to make sure that Superhero A gets to the volcanobefore Superhero C and can save the world.Note: You must use all three modes of travel.
Answers
SOLUTION:
First, let's calculate for superhero C the villian.
Using the three modes of travelling,
He needs to cover a distance of 50 miles
If he:
i. Runs
1 mile in 2 minutes, Hence
50 miles will be in 100 minutes
ii) Flys
2 miles in 2 minutes, Hence
50 miles will be in 50 minutes
iii) Swims
4 miles in 3 minutes, Hence
50 miles will be in 37.5 minutes
Next, let's calculate for superhero A.
Using the three modes of traveling,
He needs to cover a distance of 50 miles
If he:
i. Runs
4 miles in 1 minute, Hence
50 miles will be in 12.5 minutes
ii) Flys
4 miles in 4 minutes, Hence
50 miles will be in 50 minutes
iii) Swims
3 miles in 1 minute, Hence
50 miles will be in 16.67 minutes.
Finally, let's calculate for superhero B.
Using the three modes of traveling,
He needs to cover a distance of 50 miles
If he:
i. Runs
5 miles in 1 minute, Hence
50 miles will be in 10 minutes
ii) Flys
7 miles in 2 minutes, Hence
50 miles will be in 14.29 minutes
iii) Swims
10 miles in 3 minutes, Hence
50 miles will be in 15 minutes.

Answers
Hello there. To solve this question, we'll have to remember some properties about probabilities.
Given that 14 flights are randomly selected from the record list and that the flights from Chicago to Atlanta are on time 80% of the time, we have to determine:
a) The probability that at least 9 flights are on time
If we choose a flight randomly out of the 14 and 80% of the time it is on time (success), then we can use the binomial theorem for probability:
[tex]\binom{n}{x}p^x(1-p)^{n-x}[/tex]Where p is the probability of success and x is the number of times we want to check.
In this case, let p = 80% or 0.8, n = 14, such that
[tex]\binom{14}{x}0.8^x\cdot0.2^{14-x}[/tex]To find the probability that at least 9 flights are on time, we calculate the probability that at least 5 are not on time. That is, we make
[tex]\begin{gathered} 14-x=5 \\ x=9 \end{gathered}[/tex]Thus
[tex]\binom{14}{9}0.8^9\cdot0.2^5=\frac{14!}{9!\cdot(14-9)!}\cdot0.8^9\cdot0.2^5\approx0.086[/tex]In fact, we have to sum all of the contributions as follows:
[tex]\sum ^{14}_{x=9}\binom{14}{x}0.8^x\cdot0.2^{14-x}[/tex]And we get:
[tex]\approx0.956[/tex]In other words, the probability that at least 9 flights are on time is 95.6%
b) The probability that at most 2 flights are on time
For this, we need to find the probability that at least 13 flights are not on time, such that

Answers
The perimeter of the triangle XYZ is 15.1 cm.
The two given triangles are ΔUVW and ΔXYZ are similar.
In ΔUVW ∠U=36°
In ΔXYZ ∠Y = 72° and ∠Z = 72° , ∴ ∠X = 180° - (72+72)° = 36°
Hence in the two triangles we can assume that they are similar by AAA axiom of similarity
So the sides of the triangle XYZ will be
XY = 5.7 cm
YZ = 5.7 cm
ZX = 3.7 cm
Hence the perimeter = XY+YZ+ZX = 5.7 + 5. 7+ 3.7 = 15.1 cm

We will operate as follows:
*Scale factor:
We determine the scale factor using two respective sides, that is:
[tex]9x=6\Rightarrow x=\frac{6}{9}\Rightarrow x=\frac{2}{3}[/tex]So, the scale factor is 2 : 3.
*Surface area:
We determine the surface are of each prism:
[tex]S_{A1}=(9\cdot12)+2(\frac{15\cdot9}{2})+(12\cdot\sqrt[]{15^2+9^2})+(15\cdot12)\Rightarrow S_{A1}=(108)+(135)+(36\sqrt[]{34})+(180)[/tex][tex]\Rightarrow S_{A1}=423+36\sqrt[]{34}\Rightarrow S_{A1}=632.9142682\ldots[/tex][tex]S_{A2}=(6\cdot8)+2(\frac{6\cdot10}{2})+(10\cdot8)+(8\cdot\sqrt[]{6^2+10^2})\Rightarrow S_{A2}=(48)+(60)+(80)+(16\sqrt[]{34})[/tex][tex]\Rightarrow S_{A2}=188+16\sqrt[]{34}\Rightarrow S_{A2}=281.2952303\ldots[/tex]Now:
[tex](423+36\sqrt[]{34})x=188+16\sqrt[]{34}\Rightarrow x=\frac{188+16\sqrt[]{34}}{423+36\sqrt[]{34}}\Rightarrow x=\frac{4}{9}[/tex]So, the ratio of the surface areas is 4 : 9.
*Volume:
We determine the volume of each prism and proceed as before:
[tex]V_1=\frac{9\cdot15\cdot12}{2}\Rightarrow V_1=810[/tex][tex]V_2=\frac{6\cdot10\cdot8}{2}\Rightarrow V_2=240[/tex]Now:
[tex]810x=240\Rightarrow x=\frac{240}{810}\Rightarrow x=\frac{8}{27}[/tex]So, the ratio for the volumes is 8 : 27.

Lynn is tracking the progress of her plant's growth. The plant is already 8 centimeters high. The plant grows 1.5 centimeters per day. Which function shows this relationship? y=8x+1.5y=1.5x+8y=9.5x
Answers
Given the information, we know that the plant is already 8 centimeters, therefore that would be our intercept with the y-axis (i.e. b = 8). Now, to find the slope, we have that on the first day the plant grows 1.5 centimeters, therefore for day 1, the plant is 9.5 centimeters high. With this observations we have the following:
[tex]\begin{gathered} \text{Given (0,8) and (1,9.5)} \\ m=\frac{y_2-y_1}{x_2-x_1} \\ \Rightarrow m=\frac{9.5-8}{1-0}=1.5 \\ m=1.5 \end{gathered}[/tex]Using the formula y=mx+b, we obtain the desired function:

Given triangle ABC below, if angle B=(x-60)^ and angle C=(x- 45)^ find the measure of angle x
Answers
Given:
m∠B = (x - 60)°
m∠C = (x - 45)°
Opposite angle = x°
Let's find the measure of angle x.
To find the measure of angle x, apply the Exterior Angle Theorem which states that the exterior angle of a triangle is equal to the sum of the two opposite angles.
Thus, we have:
∠B + ∠C = x
(x - 60) + (x - 45) = x
Solve for x.
• Remove the parentheses and combine like terms:
x - 60 + x - 45 = x
x + x - 60 - 45 = x
2x - 105 = x
• Move all terms containing x to the left, then move 105 to the right
2x - x = 105
x = 105°
Therefore, the measure of angle x is 105°
