The stadium's seating options will include premium seats (boxes closest to the action), medium-priced seats, and budget-friendly bleachers. Your design calls for 4,500 upper-deck premium seats and 7,500 lower-deck premium seats. The team's policy is to have a 3:2 ratio of premium seats to bleacher seats. How many bleacher seats will the stadium include?
The number of bleacher seats that the stadium will include will be 8000 seats.
How to calculate the ratio?In this situation, the The team's policy is to have a 3:2 ratio of premium seats to bleacher seats.
Therefore, the total number of premium seats are:
= 4500 + 7500
= 12000
The number of bleachers will be:
= 2/3 ×12000
= 8000

State which property or properties need to be used to write each expression as a single logarithm.
a. log₄5+log₄5
Product rule of logarithms is used in the single logarithm.
A single logarithm can be expanded into many logarithms or compressed into many logarithms by using the features of log. Just another approach to write exponents is with a logarithm. As a result, the characteristics of exponents are used to infer the characteristics of logarithms.
There are 7 properties of logarithms: Product Rule, Quotient Rule, Power Rule, Zero Rule, Identity Rule, Inverse Property of Logarithm, Inverse Property of Exponent, Change of base formula.
In the equation here, only the product rule is applied.
Product rule of logarithms states that the log of a product is equal to the sum of the logs of its factors. Example: logₐ (xy) = logₐ x + logₐ y

painting worth $3000 in 2016 $4652 in 2021
if x=years since 2015 y=$ value
write an equation in point slope,
predict value in 2030
The equation for the value of the painting of the years is y = 3000 + 330.4(x).
The estimated worth of the painting in 2030 is $7956.
In 2016, the worth of the painting is $3000.
In 2021, the worth of the painting is $4652.
The increase in worth in 5 years from 2016 to 2021 is:
= $4652 - $3000 = $1652
Hence, the increase in painting worth per year will be:
= $1652 / 5 = $330.4
Now, if x is in years and y is the worth of the painting in $.
Then, the equation for the worth of a painting is:
y = 3000 + 330.4(x)
From 2015 to 2030 the span is 15 years.
Then, the value of the painting in 2030.
So,
y = 3000 + 330.4(x)
y = 3000 + 330.4 × 15
y = 3000 + 4956

The lunch bill for Eugene and Maggie totaled $20.20. Tax
on the meal was 5% and they wanted to leave a 15% tip.
How much was the meal including tax and tip?
O $24.39
O $21.21
O $22.20
O $3.03
Correct answer is A. The cost of meal in the caffeteria is 24.39.
What percentage is it?A percentage is a figure or ratio that represents a portion of 100. In addition to the percent symbol "%," the abbreviations "pct," "pct," and occasionally "pc" are also used to denote it. A% does not have any dimensions or a corresponding unit of measurement.
Your $20.20 bill is made up of the full amount (100%) plus the 15% tip, for a total of 115%. Decimal equivalent is 1.15.
Simply divide the entire charge by 1.15 to determine the price before the tip.
20.20/1.15 = 17.56
Consequently, the final amount due before the 15% tip was $17,56.
The total cost after tax and tip = 24.39

A Man rode His personal transporter 3/10 mi to the library, then 3/4 mi to class, and then 7/2 mi to his part-time job. How far did he ride his personal transporter?
If a man rode his personal transporter 3/10 mi to the library, then 3/4 mi to class, and then 7/2 mi to his part-time job, then he rode his personal transporter for 4.55 miles.
To determine how far the man rode his personal transporter we use addition.
total miles the man rode = miles to the library + miles to the class + miles to the part-time job
total miles = 3/10 + 3/4 + 7/2
As these fractions have an unlike denominator, we find a common denominator by determining the least common multiple.
As the least common multiple is equal to 20
Therefore,
total miles = 3(2)/10(2) + 3(5)/4(5) +7(10)/2(10)
total miles = 6/20 + 15/20 +70/20
total miles = 6+15+70/20
total miles = 91/20
total miles = 4.55

The function that models each variation is : [tex]z = \frac{5 x}{y}[/tex]
value of z = 20/9
What is inversely and directly variation ?The inverse variation property states that , whenever the product of values of two quantities is a constant value then there is opposite variation between them . Or we can also say that if the productive nature of two corresponding values is constant, then one quantity is inversely varies with second quantity. whereas, The direct variation state that the both values will show same pattern i.e. if one value will increase then another will also increase with the same amount or if one decrease another will also decrease.
In the question given,
First of all find the value of K in the model by putting in the values of x, y, and z so that to find the function model.
z = k (x) / (y)
put value of x=6, y=2 and z=15
15 = k (6) /2
