Answer:
21,872 tickets
Step-by-step explanation:
The computation of the number of tickets to be still sold is given below:
= Total people accommodated - total number of tickets sold yet
= 50,000 people - (13,520 tickets + 14,608 tickets)
= 50,000 people - 28,128 tickets
= 21,872 tickets

Answer:
[tex]\frac{8}{\left(-x+2\right)^2}[/tex] & [tex]x = 1, x = 3[/tex]
Step-by-step explanation:
I'm sure you are familiar with the product rule,
If y = u*v => dy/dx = u * dv/dx + v * dy/dx <----- product rule
In this case:
[tex]u=3x+2,\:v=\left(2-x\right)^{-1},\\=>\frac{d}{dx}\left(3x+2\right)\left(2-x\right)^{-1}+\frac{d}{dx}\left(\left(2-x\right)^{-1}\right)\left(3x+2\right)[/tex]
Now remember the sum rule:
[tex]\frac{d}{dx}\left(3x+2\right) = \frac{d}{dx}\left(3x\right)+\frac{d}{dx}\left(2\right),\\\frac{d}{dx}\left(3x\right) = 3,\\\frac{d}{dx}\left(2\right) = 0\\\frac{d}{dx}\left(3x+2\right) = 3[/tex]
For this second bit we apply the chain rule:
[tex]\frac{d}{dx}\left(\left(2-x\right)^{-1}\right) = -\frac{1}{\left(2-x\right)^2}\frac{d}{dx}\left(2-x\right),\\\frac{d}{dx}\left(2-x\right) = -1,\\\\=> -\frac{1}{\left(2-x\right)^2}\left(-1\right)\\=> \frac{1}{\left(2-x\right)^2}[/tex]
If we substitute these values back into the expression...[tex]\frac{d}{dx}\left(3x+2\right)\left(2-x\right)^{-1}+\frac{d}{dx}\left(\left(2-x\right)^{-1}\right)\left(3x+2\right)[/tex]
...we get the following:
[tex]3\left(2-x\right)^{-1}+\frac{1}{\left(2-x\right)^2}\left(3x+2\right)[/tex]
The rest is just pure simplification:
[tex]3\left(2-x\right)^{-1}+\frac{1}{\left(2-x\right)^2}\left(3x+2\right)\\= \frac{3}{-x+2}+\frac{3x+2}{\left(-x+2\right)^2}\\= \frac{3\left(-x+2\right)}{\left(-x+2\right)^2}+\frac{3x+2}{\left(-x+2\right)^2}\\\\= \frac{3\left(-x+2\right)+3x+2}{\left(-x+2\right)^2}\\\\= \frac{8}{\left(-x+2\right)^2}[/tex]
Now let's equate this to equal 8 for the second bit and solve for x:
[tex]\frac{8}{\left(-x+2\right)^2}=8,\\\frac{8}{\left(-x+2\right)^2}\left(-x+2\right)^2=8\left(-x+2\right)^2,\\8=8\left(-x+2\right)^2,\\\left(-x+2\right)^2=1,\\x = 1, x = 3[/tex]

A triangle has two sides of 30 meters and 26 meters, and the angle between them is an obtuse angle. If the area of the triangle is 300 sq. Meters, find the measure of the obtuse angle (to the nearest degree).
Answer:
130°
Step-by-step explanation:
Using the formula
Area of the triangle = 1/2 absin theta
a and b are the sides
theta is the obtuse angle
Given
a = 30m
b = 26m
Area = 200m²
Required
theta
Substitute into the formula;
300 = 1/2(30)*(26)sin theta
300 = 15*26sin theta
300 = 390 sintheta
sin theta = 300/390
sin theta = 10/13
sin theta = 0.7692
theta = arcsin(0.7692)
theta = 50.28degrees
Since the angle is obtuse, it must lie between 90 and 180degrees
theta = 180-50.28
theta = 129.72°
Hence the measure of the obtuse angle to the nearest degree is 130°

y=-2/3x-4/3
y=-2/3x-10/3
y=-2/3x-2/3
y=-2/3x-17/4
Answer:
C) y= 2/3x -2/3
Step-by-step explanation:
(y-y1)=m(x-x1)
y+2=2/3(x+2)
y+2= 2/3x + 4/3
y= 2/3x -2/3
A quadrilateral has the following vertices on a coordinate plane:
================================================
Explanation:
We'll only focus on points J and K.
J = (3, -6)
K = (-1, -6)
Because these two points have the same y coordinate (which is -6), this means we can ignore those values and subtract the x coordinates
3 minus (-1) = 3 - (-1) = 3 + 1 = 4
Or we could plot points J and K on the same xy grid system, and count out the number of spaces between J and K. You should count out 4 spaces.
This means segment JK is 4 units long.
Answer:
The answer is -10

mary says that the expression a/2 has no terms because there are no plus or minus signs explain whether her reasoning is correct
Answer:
No, her reasoning is wrong
Step-by-step explanation:
Her reasoning is not correct because for one the expression clearly has a term. a/2 is a term on its own. So she concluding that a/2 isn't a term is quite wrong. Again, her basis for conclusion being that there exists no addition or subtraction signs makes the equation not being a term wrong, as well. Even though there isn't and subtraction nor addition sign, it does not stop it from being any less of a term

Substitute and to determine if the two expressions are equivalent.
Which statements are true? Select the three correct answers.
3(2t+5). 6t+15
The value of both expressions when t=3 is 33.
The value of both expressions when t=3 is 23.
The value of both expressions when t=6 is 41.
The value of both expressions when t=6 is 51.
The two expressions are equivalent.
The two expressions are not equivalent.
Answer:
A and D and E
Step-by-step explanation:
Substitute the variable(in this case) t for 3, then use the order of operations to simplify(PEMDAS), which will give you 33 for both expressions. To see if two expressions are equivalent, you need to substitute the variable for an odd number AND an even number, so next, substitute the variable t for the number 6, which will give you 51 for both expressions. That means the expressions are equivalent

Amir stands on a balcony and throws a ball to his dog, who is at ground level.The ball's height (in meters above the ground), x seconds after Amir threw it, is modeled by How many seconds after being thrown will the ball hit the ground?
Answer:
6 seconds
Step-by-step explanation:
The computation of the number of second would be
In the case when the ball would hit the ground, the ball height would be zero
So the following equation would be
[tex]0 = -(x -2)^2 + 16\\\\(x -2)^2 = 16\\\\x - 2 = \sqrt{16}\\\\x -2 = 4\\\\x = 6[/tex]
So the number of seconds is 6

3&4. using the diagrams, is there enough information given to prove that the triangles are congruent? if so, state the theorem you would use
5&6. name the third congruence statement that is needed to prove that ABC is congruent to XYZ using the given theorem
Answer:
3. There is enough information to prove that ΔABC and ΔDEF are congruent using the Angle-Side-Angle (ASA) congruency theorem
4. More information is required to prove that ΔGFH and ΔJKL are congruent
5. ∠B ≅ ∠Y
6. ∠A ≅ ∠X
Step-by-step explanation:
3. In triangle ΔABC, and triangle ΔDEF, we have;
Corresponding angles ∠A and ∠D are congruent
Corresponding angles ∠C and ∠F are congruent
Corresponding side in between the given angles [tex]\overline{AC}[/tex] and [tex]\overline{DF}[/tex] are congruent
Therefore ΔABC is congruent to ΔDEF by the Angle-Side-Angle (ASA) rule of congruency
4. The corresponding angles ∠F and ∠J in triangle ΔGFH and triangle ΔJKL are congruent as well as the corresponding adjacent sides to the given angles and the corresponding opposite sides to the given angles are congruent, however, there is not enough information to prove that the two triangles are congruent
The included angles, ∠H and ∠L between the sides congruent corresponding sides should be congruent or the other adjacent sides [tex]\overline{FG}[/tex] and [tex]\overline{JK}[/tex] to the congruent angles ∠F and ∠J should be congruent for the triangles ΔGFH and ΔJKL to be congruent
5. Given [tex]\overline{AC}[/tex] ≅ [tex]\overline{XZ}[/tex], ∠C ≅ ∠Z, using the Angle-Angle-Side, AAS, rule of congruency, we have;
The angles adjacent to ∠C and ∠Z, and opposite to [tex]\overline{AC}[/tex] and [tex]\overline{XZ}[/tex], which are B and ∠Y are congruent
Therefore, we have;
∠B ≅ ∠Y using AAS rule of congruency
6. Using Angle-Side-Angle, ASA, rule, given;
[tex]\overline{AC}[/tex] ≅ [tex]\overline{XZ}[/tex], ∠C ≅ ∠Z, then the angles on the other side of [tex]\overline{AC}[/tex] and [tex]\overline{XZ}[/tex] which are ∠A and ∠X should be congruent, we have;
∠A ≅ ∠X
