The number of tickets for adults is 210 and the number of tickets for children is 83.
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 x be the number of tickets for adults and y be the number of tickets for children.
From the problem:
x + y = 293
25.50x + 8y = 6019
After solving with the substitution method:
[tex]\rm 25.5\left(293-y\right)+8y=6019[/tex]
y = 83
x = 210
Thus, the number of tickets for adults is 210 and the number of tickets for children is 83.

Do the side lengths 4, 8, and 10 form a triangle? Select the correct answer and reasoning. Question 19 options: A) Yes, because the sum of any two side lengths is greater than the third side length. B) No, because the third side length is greater than the sum of the other two side lengths. C) Yes, because the sum of all three side lengths is greater than 20. D) No, because 4 + 8 is greater than 10.
Answer:
A) Yes, because the sum of any two side lengths is greater than the third side length.
Step-by-step explanation:
All triangles have a property that the sum of two side lengths is greater than the remaining side length.
4 + 8 = 12 > 10, making it a triangle

Answers:
(a) x = 0.5
(b) Given Below.
Explanation:
(a)
[tex]4^x = 2[/tex]
apply ln both sides
[tex]ln(4^x) = ln(2)[/tex]

[tex]ln( 4^x) = ln(5)[/tex]
simplify
[tex]xln( 4) = ln(5)[/tex]
divide both sides by ln(4)
[tex]x =\frac{ ln(5)}{ln(4)}[/tex]
simplify
[tex]x =1.160964047...[/tex] The value is endless and continues.

Kurt has $9,000 in an account. The interest rate is 5% compounded annually. To the nearest cent, how much will he have in 1 year? Kurt has $ 9,000 in an account . The interest rate is 5 % compounded annually . To the nearest cent , how much will he have in 1 year ?
Answer:
$9450
Step-by-step explanation:
Answer:
A = $9,450.00
A = P + I where
P (principal) = $9,000.00
I (interest) = $450.00
Calculation Steps:
First, convert R as a percent to r as a decimal
r = R/100
r = 5/100
r = 0.05 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 9,000.00(1 + 0.05/1)(1)(1)
A = 9,000.00(1 + 0.05)(1)
A = $9,450.00
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $9,000.00 at a rate of 5% per year compounded 1 times per year over 1 years is $9,450.00.

According to the graph, what is the value of the constant in the equation
below?
Height = Constant - Width
Answer:
B) 0.5
Step-by-step explanation:
The given formula is:
Height = Constant * Width
You may now choose any point on the graph (the horizontal line represents a point for width, and the vertical line represents a point for height) and put it into the specified formula. Let's test the two supplied points (2, 1):
Now, 2 is on the horizontal line, so we put it in for width, and 1 is on the vertical line, so we plug that in for height. When we do it, we get:
1 = C * 2
(In the expression above we need to solve for C, and we can do that by dividing both sides by 2)
C= 1/2 = 0.5
So, the answer is 0.5 or option B.
7(x + 1) -2 =5 (x + 1) +2
Answer:
x = 1
Step-by-step explanation:
Simplifying
7(x + 1) + -2 = 5(x + 1) + 2
Reorder the terms:
7(1 + x) + -2 = 5(x + 1) + 2
(1 * 7 + x * 7) + -2 = 5(x + 1) + 2
(7 + 7x) + -2 = 5(x + 1) + 2
Reorder the terms:
7 + -2 + 7x = 5(x + 1) + 2
Combine like terms: 7 + -2 = 5
5 + 7x = 5(x + 1) + 2
Reorder the terms:
5 + 7x = 5(1 + x) + 2
5 + 7x = (1 * 5 + x * 5) + 2
5 + 7x = (5 + 5x) + 2
Reorder the terms:
5 + 7x = 5 + 2 + 5x
Combine like terms: 5 + 2 = 7
5 + 7x = 7 + 5x
Solving
5 + 7x = 7 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
5 + 7x + -5x = 7 + 5x + -5x
Combine like terms: 7x + -5x = 2x
5 + 2x = 7 + 5x + -5x
Combine like terms: 5x + -5x = 0
5 + 2x = 7 + 0
5 + 2x = 7
Add '-5' to each side of the equation.
5 + -5 + 2x = 7 + -5
Combine like terms: 5 + -5 = 0
0 + 2x = 7 + -5
2x = 7 + -5
Combine like terms: 7 + -5 = 2
2x = 2
Divide each side by '2'.
x = 1
Simplifying
x = 1
Answer:
Hello! The answer is x = 1.
Step-by-step explanation:
To solve this equation, we need to find x.
The first step in approaching this problem would be to use the distributive property:
7(x + 1) - 2 = 5(x + 1) + 2 will turn into:
7x + 7 - 2 = 5x + 5 + 2
Now, you can combine like terms on each side of the equation:
7x + 5 = 5x + 7
Now, you want to get the x's on one side and the whole numbers on the other side. In order to do this, we will subtract 5 from both sides and subtract 5x from both sides:
7x + 5 = 5x + 7
-5x -5 -5x -5
This will leave us with:
2x = 2
We will have to now divide both sides by 2 to get x by itself:
2x = 2
-- --
2 2
This leaves us with the result: x = 1
Your little brother just learned how to flip and catch a coin. He believes that by catching the coin in mid-air, he can influence the probability that it will land heads up. Based on your understanding of theoretical probability, explain to your little brother why his theory of influence is false.
By performing two experiments a lot of times, your brother will see that catching the coin mid-air does not affect the probability.
How to explain that the theory is false?We assume that the probability of each outcome of the coin is equal, so the probability of getting tails is 0.5 and the probability of getting heads is 0.5
Then, you can say to your brother to perform his experiment a lot of times. In two ways.
First, he lets the coin came down to his hand around 100 times.
Then, he catches the coin in mid-air another 100 times.
He will see that the probability of getting heads (or tails) is (almost) the same in both cases, this will mean that his theory is false.

Step-by-step explanation:
Rewrite a percentage as a decimal: [tex]\frac{32.5}{100}[/tex]
Convert decimals to integers: [tex]\frac{325}{100}[/tex]
Reduce the fraction: [tex]\frac{13}{40}[/tex]
Answer: [tex]\frac{13}{40}[/tex]
32.5% as a fraction in simplest form is 13/40.
Here we have to find fractional form of 35 percent
Since we knw that,
A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
To convert a percentage to a fraction,
we can simply write it as a fraction with a denominator of 100.
Then,
we simplify the resulting fraction to its simplest form.
For 32.5%,
we can write this as,
⇒ 32.5/100
Now, we can simplify this fraction by dividing both the numerator and denominator by their greatest common factor (GCF).
The GCF of 32.5 and 100 is 12.5,
so we can divide both by 12.5,
⇒ 32.5/100 = (32.5 ÷ 12.5) / (100 ÷ 12.5)
= 13/40
Therefore, 32.5% as a fraction in simplest form is 13/40.
