The linear equation 20x + 35(60-x) = 1500 can be solved to find the number of tickets.
What is an equation?
An equation is a formula in mathematics that expresses the equivalence of two expressions by linking them with the equals symbol =. The word equation and its related terms in various languages may have somewhat different definitions; for example, in French, an equation is described as including one or more elements, but in English, an equation is any well-formed formula that includes two expressions linked by an equals sign.
Let the number of advance tickets sold = x
And then, the number of same-day tickets sold = 60 - x
Then, the equation formed is
20x + 35(60-x) = 1500
=> 20x + 2100 - 35x = 1500
=> -15x = 1500 - 2100
=> x = -600/ -15 = 40
Hence, the number of advance tickets sold = 40
And the number of same-day tickets sold = 60 - 40 = 20

A trapezoid has coordinates F (−9, 6), G (−6, 9), H (−3, 9), and I (0, 6).
a. Dilate the trapezoid by a scale factor of 1/3 with a center of dilation at the origin.
b. Is the dilation a reduction or an enlargement? Explain your reasoning.
a) the coordinates of the dilated trapezoid is F'(-3, 2), G'(-2, 3), H'(-1, 3), I'(0, 2)
b) Dilation is reduction.
In this question, we have been given a trapezoid has coordinates F (−9, 6), G (−6, 9), H (−3, 9), and I (0, 6).
a. We need to dilate the trapezoid by a scale factor of 1/3 with a center of dilation at the origin.
The scale factor is 1/3
so, the coordinates of the image would be,
F' = 1/3 (-9, 6)
= (-3, 2),
G' = 1/3(-6, 9)
= (-2, 3),
H' = 1/3 (−3, 9)
= (-1, 3),
and I' = 1/3 (0, 6)
= (0, 2)
b. We know that a dilation is a geometric transformation that either enlarges or reduces a figure in size.
As we know, if the scale factor is between 0 to 1 then the image is reduction and if the scale factor is greater than 1 then the image is enlargement.
Here, scale factor is 1/3 which is 0 < 1/3 < 1
So, in this case the dilation is reduction.
Therefore, a) the coordinates of the dilated trapezoid is F'(-3, 2), G'(-2, 3), H'(-1, 3), I'(0, 2)
b) Dilation is reduction.

The first four terms of the binomial series are 1, x, - x²/2 and - 1/32x³ respectively.
The binomial provided to us is [tex](1+2x)^{1/2}[/tex]
To find out the first four terms of the binomial, we shall first extend the standard binomial (1+x)^n.

As we can see here,
The value of x = 2x,
The value of n = 1/2.
We get,
(1+2x)^1/2 = 1 + 1/2(2x) + [1/2(1/2-1)/2!]x² + [1/2(1/2-1)(1/2-2)/3!]x³ +

number line with a closed circle plotted at negative eight and arrow pointing left
The graph of the solution to this inequality is: C. number line with an open circle plotted at negative eight and arrow pointing left.
What is a number line?A number line simply refers to a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.
Next, we would solve the given inequality as follows:
−0.4b + 2.4 < 5.6
Subtracting 2.4 from both sides, we have:
−0.4b + 2.4 - 2.4 < 5.6 - 2.4
−0.4b < 5.6 - 2.4
−0.4b < 3.2
Dividing both sides by -0.4, we have:
b < -3.2/0.4
b < -8
In conclusion, the circle on a number line should be open and would point to the left when the inequality symbol is <.

Supposing a three variable function F(x,y,z) = 0, then the implicit derivatives are given as follows:
[tex]\frac{\partial z}{\partial x} = -\frac{F_x}{F_z}[/tex][tex]\frac{\partial z}{\partial y} = -\frac{F_y}{F_z}[/tex]In standard format, the function is given as follows:

The rate at which a population of bacteria grows is proportional to the size of the population. At 1:00 PM, the population of a certain strain of bacteria was 5,400. At 1:20 PM, the population was 9,000. At what time will the population of bacteria be 25,000?
The time at which the population of bacteria will be 25,000 is 2:49 pm.
Given that:-
Population of bacteria at 1:00 PM = 5,400
Population of bacteria at 1:20 PM = 9,000
The rate at which a population of bacteria grows is proportional to the size of the population.
We have to find the time at which the population of bacteria will be 25,000.
The rate at which population of bacteria grows = 3600 bacteria/ 20 min = 180 bacteria/min
Let the population of bacteria takes t minutes to become 25,000.
Hence, we can write,
5400 + 180t = 25000
180t = 25000 - 5400
180t = 19600
t = 19600/180
t = 108.889
t = 109 minutes = 1 hour 49 minutes
Hence, the time will be 2:49 pm.

What are fractions?In mathematics, a fraction is represented by a numerical value that represents a portion of an entire. A fraction is a piece or section of a whole, where the whole can be any number, a particular value, or an object.Let's assume the monthly income of the man is x.
Income spend on children's school fees = [tex]\frac{1}{4} x[/tex]
Income spend on home affairs = [tex]\frac{3}{5} x[/tex]
The fraction of his income left with the man is,
Total income - Total expenditure
= [tex]x-(\frac{1}{4} x + \frac{3}{5} x)[/tex]
= [tex]x-(\frac{5x+12x}{20})[/tex]

If the difference is a negative number, record it as such.
The difference between each annual wage figure and the poverty threshold is as shown in the attached completed table.
How to calculate Annual Income?
Annual Income is a term in economics that is calculated by multiplying the Hourly wage by 4,000 hours.
Now, the Difference between annual wage and the federal poverty line is calculated by subtracting the 2019 Poverty threshold of $13,011 from the Annual Income.
