The number of tickets sold at a regular price is 20.
The linear equation:
an algebraic equation of the form y=mx + b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.
Let x be the number of regular admission and y be the number of students.
The first statement is 48 tickets are sold. By this we get the first equation:
x + y = 48 ----------(1)
The second statement is the total collection for the ticket is $300. Form this we get the second equation:
8x + 5y = 300 --------(2)
Multiplying the equation by 5 we have:
5x + 5y = 240 --------(3)
Now subtracting equation (3) from (2) we get:
3x = 60
x = 20
Therefore we get that the ticket sold at regular price is 20.

What is the slope?
The slope of the line is 1/3
First we have to choose two points from the graph
The first point = (1, -5)
The second point = (7, -3)
The slope of the line is the change is y coordinate with respect to the change in x coordinate of the function
The slope of the line m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Where m is the slope of the line
[tex](x_1,y_1)[/tex] is the coordinate of the first point
[tex](x_2,y_2)[/tex] is the coordinate of the second point
Substitute the values in the equation
The slope of the line = (-3 - (-5) / (7 - 1)
= (-3+5) / 6
= 2 / 6

The equation that could be used to find the measure of angle B is Sin B = √5/5.
According to the question,
We have the following information:
We have a right-angled triangle with all its sides given.
Now, in order to find the measurement of angle B, we will use trigonometric functions. Two functions Sin and Cos are given in options. So, we will find the values of angle B using these two.
Cos B = AB/BC
Cos B = 6/3√5
Cos B = 2/√5
Now, multiplying both the numerator and denominator by √5:
Cos B = 2√5/5
Now, this equation is not given in options. So, we will find the angle using Sin.
Sin B = AC/BC
Sin B = 3/3√5
Sin B = 1/√5
Now, multiplying both the numerator and denominator by √5:
Sin B = √5/5
Hence, the correct option is B.

The range of this function c(x) = 14x + 13 using interval notation is (13, ∞).
How to identify the domain and range any graph?In Mathematics, the horizontal portion of any graph is used to represent all domain values and they are both read and written from smaller to larger numerical values, which simply means from the left of any graph to the right.
Additionally, the vertical extent of any graph represents all its range values and they are always read and written from smaller to larger numerical values, and from the bottom of a graph to the top.

Write the equation of the line that passes through the points (1,-3) and (3,3)
The equation of line is y = 3x - 6
Define Equation of line.
A line in geometry is a collection of points that can be stretched infinitely in two different ways. To put it another way, a line is created by continually extending the two end points in any direction. As a result, we can assert that a line lacks end points. However, because it just has length and no width, it is a one-dimensional geometric form. Based on the information provided, we can create multiple forms of equations for lines algebraically, such as point slope form, slope-intercept form, and two point form. Two Point Form Formula,y - y₁ = m (x - x₁)
We have the given points,
(1, -3) and (3, 3)
Let, (x₁ , y₁) = (1, -3) and,
(x₂, y₂) = (3, 3)
Formula for equation of line is,
y - y₁ = m (x - x₁)
Where m is slope and for that we have formula for slope is
m = (y₂ - y₁) / (x₂ - x₁)
plug in the values,
m = (3 - (-3) ) / (3 - 1)
m = 6 / 2
m = 3
Now, we get the slope. Now, just put the values in equation of line formula
y - y₁ = m (x - x₁)
y - (-3) = 3 (x - 1)
y + 3 = 3x - 3
y = 3x - 6
Hence, the equation of line is y = 3x - 6

Sally adds 3.13 moles of argon to a 5.29 liter balloon that already contained 2.51 moles of argon. What
is the volume of the balloon after the addition of the extra gas?
The volume of the balloon after the addition of the extra gas is 11.87 liters
The initial volume of the balloon = 5.29 liters
Initial quantity of argon in the balloon = 2.51 mole
Here we have to use the unitary method
The volume of the 1 mole of argon = The initial weight of the balloon / Initial quantity of argon in the balloon
Substitute the values in the equation
The volume of the 1 mole of argon = 5.29 / 2.51
= 2.11 liters
Additional argon added = 2.51 mole
Total quantity of argon = 2.51 + 3.13
= 5.64 mole
The volume of the 5.64 mole of argon = 5.64 × 2.11
= 11.87 liters

The precise value of p is 4/18. Jae Hee's expected score in the game is 1.833. Jae Hee has a 1/162 chance of receiving a total score of -3. The likelihood that something will happen is defined as probability.
How to calculate Probability ?Probability is calculated by dividing the number of possible outcomes by the total number of outcomes. Probability and odds are distinct concepts. Odds are the probability that something happens divided by the probability that it does not happen. Probability is a branch of mathematics that deals with numerical representations of the likelihood of an event occurring or a statement being true.Therefore,
Value of p is,
∈p = 1
1/18 + p + 3/18 + 1/18 + 2/18 + 7/18 = 1
14/18 + p = 1
p = 4 / 18
So the exact value of p is 4/18
Expected score of the game :
∈(x) = ∈xi pi
= -3 (1/18) - 1 (4/18) + 0 (3/18) + 1 (1/18) + 2 (2/18) + 5 (7/18)
= 33/18
= 1.833
Expected score of the game Jae Hee plays is 1.833
Calculate Probability of Jae Hee getting total score of -3
p (total score -3 )
= p(x= -3) and p(x=0) + p(x=0) and p (x=3)
= 1/18 × 1/18 + 1/18 × 1/18
=1/162
Probability of Jae Hee getting total score of -3 is 1/162

salma has set up a lemonade stand outside her house and sells small cups and large cups of lemonade. each small cup holds 12 ounces of lemonade and each large cup hold 16 ounces of lemonade. salma sold 60 cups of lemonade totaling 920 ounces. determine the number of small cups sold and the number of large cups sold
If Salma sold 60 cups of lemonade with total 920 ounces, then the number of small cups is 10 and the number of large cups is 50.
The problem can be translated into a system of linear equations.
Let:
p = the number of small cups sold
q = the number of large cups sold
"Salma sold 60 cups" can be translated into equation:
p + q = 60 (equation 1)
"totaling 920 ounces" can be translated into equation:
12p + 16q = 920 (equation 2)
Multiply equation 1 by 12 then substracted from equation 2:
12p + 16q = 920
12p + 12q = 720 _
4q = 200
q = 50
Substitute q = 50 into equation 1:
p + 50 = 60
p = 10
Hence, the number of small cups = 10, the number of large cups = 50.

and u(n) = 1 ,
we need to find the recursive formula ,
We substitute n + 1 in place of n , in the equation u(n) = 4n - 1
after substitution , we get
u(n+1) = 4(n + 1) - 1

Vertical angles are congruent (equal to each other)
This means that 8x + 36 = 5x + 60
Using this equation we can solve for x
8x + 36 = 5x + 60
==> subtract 36 from both sides
8x = 5x + 24

Subtract 5x to both sides
8x - 5x + 36 = 60
3x + 36 = 60

The amount owed at the end of the 6 years duration is $10865
How to determine the amount owed in six years?The given parameters about the compound interest are
Principal Amount, P = $5300
Interest Rate, R = 8%
Time, t = 6 years
To calculate the amount owed, we make use of the following formula
A = P + CI
Where
Compound interest, CI = P(1 + R)^t - P
So, the equation becomes
A = P + P(1 + R)^t - P
Evaluate the like terms
A = P(1 + R)^t
In this question, the formula is given as
A = P(1 + r/n)^nt
Where
n = 12, i.e compounded monthly
Substitute the known values in the above equation
A = 5300 * (1 + 8%/12)^(6*12)
Express 8% as decimal
A = 5300 * (1 + 0.08/12)^(6*12)
Evaluate the sum
A = 5300 * (1.01)^(6*12)
Evaluate the exponent
A = 5300 * 2.05
Evaluate the product
A = 10865
Hence, the value of the amount after 6 years is $10865

One angle at the point at F is given that 139 degrees
We know sum of angles on a straight line is 180 degrees
Then the other angle will be
139 + a = 180
a = 180 - 139
a = 41 degrees
Now consider the triangle and find the value of x
The sum of interior angles of a triangle is 180 degrees
then
(3x+8) + (3x) + (9x+7) = 180
3x+8 +3x +9x + 7 = 180
15x + 15 = 180
15x = 180 - 15
15x = 165
x = 165/15
x = 11
Then the value of angle 3x + 8 = 3 × 11 + 8

What’s important is whether the relationship between the two is the same for all data pairs. E.g., 12/2 = 6; 36/6 = 6; 60/6 - 5, and so forth. They are all the same ratio, or rate: (6 hours)/(1 day)
