Answer: 110
Step-by-step explanation: If the drama class sold 20 more adult tickets than student tickets to the fall play, and adult tickets cost $8, then the number of adult tickets sold can be calculated by adding 20 to the number of student tickets sold and multiplying by $8. We can set up an equation to represent this relationship, where A represents the number of adult tickets sold and S represents the number of student tickets sold:
A = S + 20
A * 8 = $880
We know that the total amount collected from ticket sales was $880, and we know that adult tickets cost $8, so we can divide $880 by $8 to find the number of adult tickets sold:
A = $880 / $8
A = 110
Therefore, the drama class sold 110 adult tickets to the fall play.

The required answer choices are (i)exponential decay (ii) linear and (iii) exponential growth
What are exponential growth and exponential decay?
Quantities that fluctuate quickly are subject to exponential growth and decay. The idea of geometric progression has been used to infer exponential growth and decay. Exponential growth or exponential decay are terms used to describe quantities that vary exponentially rather than continuously.
From question,
1) The first question is like, initially delivery van price is $25,000 after 2 years, the value of the van becomes $17,500
This means it is decaying. The difference between the initial price and after 2 years price is $7500.
To be linear, further after 2 years, or from start after 6 years, the price should be $10000. But it is given to be $12250.
Thus exponential decay.
2) In the second, Initially, a laptop had 100% battery life. After 3 hours, the laptop has 60% battery life. Thus the loss in 3 hours is (100 - 60) = 40%.
After 4 hours, the loss is (60 -20) = 40%
As the loss is the same in equal intervals of time, the decay is linear.
3) In the third one, A tiger reserve had an initial population of 20 tigers.
After 5 years the population was 30 tigers, thus the growth is (30-20) =10.
After 10 years, the population was 45 tigers. Thus the growth is (45-30) = 15.
Thus the increase is non-linear, and so is exponential growth.

The solutions to the x and w variables are x = 2097153 and w = (6)⁻²/⁵
How to determine the solution to the variables?From the question, we have the following parameters that can be used in our computation:
1/7log(x - 1) = 3log(2)
3 ln(w + 6) = 5 ln(6)
Solving the equation (1), we have the following equation
1/7log(x - 1) = 3log(2)
Multiply both sides of the equation by 7
So, we have the following representation
log(x - 1) = 21log(2)
Apply the power rule of logarithm
log(x - 1) = log(2)²¹
By comparison, we have
x - 1 = (2)²¹
Evaluate the exponent
x - 1 = 2097152
So, we have
x = 2097153
Solving the equation (2), we have the following equation
3 ln(w + 6) = 5 ln(6)
Multiply both sides of the equation by 1/3
So, we have the following representation
ln(w + 6) = 5/3 ln(6)
Apply the power rule of logarithm
ln(w + 6) = ln(6)³/⁵
By comparison, we have
w + 6 = (6)³/⁵
So, we have
w = (6)⁻²/⁵
Hence, the solutions are x = 2097153 and w = (6)⁻²/⁵

The length of the PM is 6 if ABCD is congruent to MNOP.
What do you mean by congruent?When it comes to geometry, two figures or objects are said to be congruent if they are the same size and shape, or if one is the mirror image of the other.
More specifically, two sets of points are said to be congruent if—and only if—they can be changed into one another by an isometry, which is a combination of rigid motions including translation, rotation, and reflection. This indicates that either object may be exactly aligned with the other object by moving and reflecting it, but not by resizing it. If we can cut out and then perfectly match up two separate plane figures on a piece of paper, they are then congruent. I'm allowed to turn the paper over.
Here both the given figures are congruent figures. So, their shape and size must be equal.
Therefore from the two figures, PM=DA
So, PM=6

Answer:
1 divided by 7 raised to the third power
Step-by-step explanation:
To find the equivalent expression, we can start by applying the rule for multiplying powers with the same base:
(7^(-2)) * (7^3) = 7^(-2+3) = 7^1 = 7
Then, we can apply the rule for raising a power to a power:
7^1 = (7^1)^(-3) = 7^(-3)
Finally, we can apply the rule for raising a number to a negative power:
7^(-3) = 1 / (7^3) = 1 / 343 = 1/7^3
Therefore, the equivalent expression is 1 divided by 7 raised to the third power.

The long term behavior of the rational function f(x) = (x² - 3) / (x³ + 2) is 0, for the rational function g(x) = (x³ - 3) / (x³ + 2) is 1 and for the rational function h(x) = (x⁴ - 3) / (x³ + 2) does not exist.
How to determine the long run behavior of a rational function
In this case we find three rational functions, that is, functions of the form:
m(x) = p(x) / q(x)
Where:
p(x) - Function numerator.q(x) - Function denominator.Please notice that both numerator and denominator are polynomic functions, the long run behavior of the function depends on the grades of numerator and denominator according to these rules:
If the grade of the numerator is greater than the grade of the denominator, then long run behavior is divergent as x → ± ∞.If the grade of the numerator and the grade of the denominator are the same, then the function tends to a / b as x → ± ∞, where a and b are the lead coefficients of the numerator and the denominator, respectively.If the grade of the numerator is less than the grade of the denominator, the function tends to be 0 as x → ± ∞.Now we proceed to analyze the long run behavior of each rational function:
Case 1: f(x) = (x² - 3) / (x³ + 2)
Grade of numerator: 2, grade of denominator: 3
Result: 0
Case 2: g(x) = (x³ - 3) / (x³ + 2)
Grade of numerator: 3, grade of denominator: 3

P = 2( 36x + 42x)
P = 2( 78x )
P = 156x
14.) perimeter of a scalene triangle
P = a + b + c
P = 3x + 3(x – 2) + 4x + 8
P = 3x + 3x –6 + 4x +8
P = 6x + 4x –6 + 8
P = 10x + 2
in factorise form
P = 2(5x + 1)

Use the formula A=P\left(1+r/n)^nt to solve the compound interest problem.
Find how long it takes a 1700$ investment to earn 500$ interest if it is invested at 2% interest compounded quarterly.
500$ interest will be earned in approximately years. (Round to the nearest tenth.)
It will take 12.91 years to earn $ 500 in interest
What is Compound interest:
Compound interest refers to the interest added to a loan or deposit. It is the concept that we employ every day on a regular basis. Amounts are based on both the principal amount and Rate of interest when calculating compound interest.
The formula used for
Amount, A = P(1+r/n)^ntP = Principal amount
r = Rate of interest
n = Number of compounds in a year
t = Time period in years
And the formula for
Compound Interest, C.I = A - P
Here we have
Principal amount = 1700,
Rate of interest = 2% = 2/100 = 0.02 on decimals
Given that compound interest gained = $ 500
Number of compounds = 4 times
Let a be the time period
By the given formula,
Amount, A = 1700(1+0.02/4)^4t
= 1700(1+0.005)^4t
= 1700 (1.005)^4t
Compound interest = 1700 (1.005)^4t - 1700
From the given data,
Compound interest = $ 500
=> 1700 (1.005)^4t - 1700 = 500
=> 1700 (1.005)^4t = 2200
=> (1.005)^4t = 1.294
Take logs on both sides
=> log (1.005)^4t = log 1.294
=> 4t log (1.005) = log (1.294)
=> 4t = log(1.294)/log(1.005)
=> 4t = 0.111934276/ 0.00216606176
[ Use calculator for log(1.294) and log(1.005) ]
=> 4t = 51.6764012
=> t = 12.9191003
=> t = 12.91
Therefore,
It will take 12.91 years to earn $ 500 in interest
