Answer:
90 degrees.
Step-by-step explanation:
Assuming x is the bottom right of the blue triangle, x would be 90 degrees, since the triangle has a right angle.
Right angles are always 90 degrees.

Theater tickets to the Livingston Theater production cost $18 for students and $25 for non-students. If 320 tickets were sold, and the total sales of all of the tickets was $6719, how many student tickets were sold
The total number of student tickets were sold is 183 if the theater production cost $18 for students and $25 for non-students.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let's suppose the x number of students tickets were sold and
y number of tickets were sold for non students.
Then we can frame two linear equations:
x + y = 320 ...(1)
18x + 25y = 6719 ...(2)
From equation (1) take the value of y and plug into the equation (2)
18x + 25(320 - x) = 6719
18x + 8000 - 25x = 6719
7x = 1281
x = 183 tickets
Thus, the total number of student tickets were sold is 183 if the theater production cost $18 for students and $25 for non-students.

tom is planning a party for five friends at a game arcade. He can buy different numbers of game tokens for the prices shown on the table
each friend will have 25 game tokens.
how much money could tom save, in dollars, if he buys all 125 tokens before the party rather than separately as each friends arrive?
Answer:
He can save 20 dollars
Step-by-step explanation:
He can buy one 100 token amount and one 25 token amount. This will cost 20 + 10 dollars, or 30 dollars. If each friend buys 25 tokens, it will cost
10 * 5 dollars, or 50 dollars. 50 - 30 = 20. So he can save 20 dollars.

Please Help Me with All of these!!!!!! Conditional Probability
The questions are all illustrations of conditional probabilities, and they can be solved using the general conditional probability formula; P(A|B) = P(A and B)/P(B)
How to determine the conditional probabilities?The conditional probability P(A|B) is calculated using:
P(A|B) = P(A and B)/P(B)
Using the above formula, we have:
P(has at least 4 sides| not a hexagon) = 38/50
P(has at least 4 sides| not a hexagon) = 0.76
P(not a square | has less than 7 sides) = 30/45
P(not a square | has less than 7 sides) = 0.67
P(not an octagon | not a triangle) = 39/51
P(not an octagon | not a triangle) = 0.76
P(octagon | sum of interior angle measures is at least 600) = 9/25
P(octagon | sum of interior angle measures is at least 600) = 0.36
Students in Wayland high schoolThe conditional probability is calculated using:
P = P(perfect attendance and honor roll)/P(Honor roll)
So, we have:
P = 25%/38%
Evaluate
P = 0.66
Hence, the probability that a student has a perfect attendance, given that he made the honor roll is 0.66
Homes on the marketThe conditional probability is calculated using:
P = P(Home has a pool and at least 3 bedrooms)/P(at least 3 bedrooms)
So, we have:
P = 25%/70%
Evaluate
P = 0.36
Hence, the probability that a home has a pool, given that it has at least 3 bedrooms is 0.36
Conditional probability using Venn diagramUsing the conditional probability formula in (a), we have:
P(uses Ins tag ram| does not use Sna pch at) = 45/(20 + 45)
P(uses Ins tag ram| does not use Sna pch at) = 0.69
P(does not use Ins tag ram| uses Sna pch at) = 25/(30 + 25)
P(uses Instag ram| does not use Sna pch at) = 0.45
Sports and Part-time jobUsing the conditional probability formula in (a), we have:
P(plays sport| has a part-time job) = 22/68
P(plays sport| has a part-time job) = 0.32
P(has a part-time job| plays sport) = 22/40
P(has a part-time job| plays sport) = 0.55

Step-by-step explanation:
General equation of an ellipse
[tex]\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1 \quad \textsf{where }(h \pm a,k)\: \textsf{and}\:(h, k \pm b)\: \textsf{are the vertices}[/tex]
Major Axis: longest diameter of an ellipse
Minor Axis: shortest diameter of an ellipse
Major radius: one half of the major axis
Minor radius: one half of the minor axis
If a > b the ellipse is horizontal, a is the major radius, and b is the minor radius.
If b > a the ellipse is vertical and b is the major radius, and a is the minor radius.
Given equation:
[tex]\dfrac{(y-4)^2}{25}+\dfrac{x^2}{9}=1[/tex]
[tex]\implies \dfrac{x^2}{9}+\dfrac{(y-4)^2}{25}=1[/tex]
Comparing with the general equation:
h = 0a² = 9 ⇒ a = 3k = 4b² = 25 ⇒ b = 5As b > a then the ellipse is vertical and b is the major radius.
⇒ Major axis = 2 × Major Radius
= 2b
= 2 × 5
= 10

A truck driver needs to drive 400 miles. The drivers average speed for the first 180 miles is b miles per hour. The drivers average speed for the rest of the trip is c miles per hour. Enter an equation for the total time, t, in hours it took the driver to complete the entire trip
Step-by-step explanation:
speed = distance/time
time = t = distance/speed
t = 180/b + (400-180)/c = 180/b + 220/c = 20(9/b + 11/c)

Need help,will give 20 points.Use the rectangle to find the measure of the following angles measure ane BAC=25
1) All angles of a rectangle are right angles, so the measure of angle CBA is 90 degrees.
2) Since all angles of a rectangle are right angles, angle BAD measures 90 degrees. Subtracting the 25 degrees of angle BAW from this, we get that angle CAD has a measure of 65 degrees.
3) Opposite sides of a rectangle are parallel, so by the alternate interior angles theorem, the measure of angle ACD is 25 degrees.
4) Because diagonals of a rectangle are congruent and bisect each other, this means BW=WA. So, since angles opposite equal sides in a triangle (in this case triangle ABW) are equal, the measure of angle ABW is 25 degrees. This means that the measure of angle CBD is 90-25=65 degrees.
5) In triangle AWB, since angles in a triangle add to 180 degrees, angle BWA measures 130 degrees.
6) Once again, since diagonals of a rectangle are congruent and bisect each other, AW=WD. So, the measures of angles WAD and ADW are each 65 degrees. Thus, because angles in a triangle (in this case triangle AWD) add to 180 degrees, the measure of angle AWD is 50 degrees.
Given that 7^2 = 12^x, evaluate 12^2x.
Answer:
12^2x = 7^4 = 2401
7^2=12^x
We know that a^x * a^x = a^(x+x) or a^2x
Multiply each side by 12^x
7^2 * 12^x=12^x * 12^x
7^2 * 12^x = 12^(x+x)
Replace 12^x with 7^2 on the left hand side since they are equal
7^2 * 7^2 = 12^ (2x)
7^(2+2) = 12^(2x)
7^4 = 12^2x
2401 = 12^2x

From the observation deck of a skyscraper, Brandon measures a 45^{\circ} ∘ angle of depression to a ship in the harbor below. If the observation deck is 1140 feet high, what is the horizontal distance from the base of the skyscraper out to the ship? Round your answer to the nearest tenth of a foot if necessary.
The horizontal distance from the base of the skyscraper out to the ship will be 1140 feet.
What is trigonometry?Trigonometry is the branch of mathematics which set up a relationship between the sides and angle of the right-angle triangles.
Given that:-
The angle is = 45The height of the skyscraper is 1140 feet.The horizontal distance will be calculated by applying the angle property in the right angle triangle.
tan45 = ( P / B )
B = P / tan45
B = P Since ( tan45 =1 )
B = 1140 feet.
Therefore the horizontal distance from the base of the skyscraper out to the ship will be 1140 feet.
