Answer:

36 feet

Step-by-step explanation:

Let us first find the area of the of the flower bed. It is a rectangle, so:

A = 18 * 4.5 = 81 square feet

The square flower bed has the same area, therefore, the length of the sides of the flower bed can be gotten. The area of a square is:

\(A = L^2\)

\(81 = L^2\\\\L = \sqrt{81}\)

L = 9 feet

Next, we need to find the perimeter of the square flower bed:

P = 4L

=> P = 4 * 9 = 36 feet

He needed 36 feet of fence to enclose the entire square flower bed.

The expression (9.6 × 10³) × (6.7 × 10²) can be simplified in scientific notation as  6.432 × 10⁶ , 64.32 × 10⁵ and (9.6 × 6.7) × (10³ × 10²) .

Here, we have,

Scientific notation is a means to express values that are either too big or too little to be conveniently stated in decimal form (typically would result in a long string of digits). It is also known as standard form in the UK and scientific form, standard index form, and standard form. Scientists, mathematicians, and engineers frequently utilize this base ten notation because it can make some mathematical operations simpler.

The given expression is : (9.6 × 10³) × (6.7 × 10²)

First we multiply the decimal terms separately.

So  (9.6 × 6.7) = 64.32 and now we multiply the power terms

10³ × 10² = 10²⁺³ = 10⁵ ( By using the properties of exponents)

So in proper scientific notation 64.32 × 10⁵ = 6.432 × 10⁶

Which can also be written as 6.432 × 10⁶ or (9.6 × 6.7) × (10³ × 10²) .

Graph third represents the situation if a bookstore sells art books for $25 each. There are 16 books at the store option (C) is correct.

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.

It is given that:

A bookstore sells art books for $25 each. There are 16 books at the store.

Let x be the total number of books sold and y be the total amount earned:

The linear equation can be framed as follows:

y = 25x

After plotting the graph of the above linear equation we will get a graph exactly the same as mentioned in the graph third.

Thus, the graph third represents the situation if a bookstore sells art books for $25 each. There are 16 books at the store option (C) is correct.

The numbers that cannot be probabilities are: square root of 2, -53, 5/3, and 1.31.

Probability is a measure of the likelihood of a particular event occurring in a random experiment. It is a value between 0 and 1, with 0 indicating that an event is impossible, and 1 indicating that an event is certain to occur.

In statistics, probability is used to make predictions or draw inferences about a population based on a sample of data. For example, if we were to flip a coin, the probability of getting heads is 0.5, or 50%. In general probability can be defined as the ratio of the number of favorable outcomes to the total number of possible outcomes, which is the mathematical framework behind the random experiments.

From the set of numbers, 0, 0.08, and 3/5 are all possible values of probability.

Therefore, square root of 2, -53, 5/3, and 1.31 cannot be probabilities.

There is null difference in the total sales between the two time periods.

To calculate the difference in total sales between the new box of donuts sold over 6 months this year and the original box sold over 6 months last year, we need additional information such as the number of dozens sold in each period. Let's assume that in both periods, 100 dozens of donuts were sold.

For the new box sold this year:

Total sales = Selling price per dozen * Number of dozens sold

Total sales = $6.99 * 100 = $699

For the original box sold last year:

Total sales = Selling price per dozen * Number of dozens sold

Total sales = $6.99 * 100 = $699

The difference in total sales between the two periods is $699 - $699 = $0. Therefore, there is no difference in the total sales between the new box sold over 6 months this year and the original box sold over 6 months last year, assuming both periods had the same number of dozens sold.

The conversion of a unary one-to-one relationship, a unary one-to-many relationship, and a unary many-to-many relationship into relational tables have in common the creation of a separate table to represent the relationship.

This table will have a foreign key referencing the primary key of the entity involved in the relationship.

In each case, the entity is represented by a single table with one or more attributes, and the relationship between the entity and itself is represented by one or more columns in that table. The differences between these types of relationships lie in the cardinality of the relationship and how it is represented in the table structure.

For a unary one-to-one relationship, the entity table will have a foreign key column that references itself, which enforces the one-to-one relationship between two instances of the same entity.

For a unary one-to-many relationship, the entity table will have a foreign key column that references itself, but multiple instances of the same entity can reference a single instance of the same entity.

For a unary many-to-many relationship, the entity table will need to be split into two tables, with a third "junction" table linking them together. The junction table will have two foreign key columns, each referencing the primary key of one of the two entity tables, to represent the many-to-many relationship between instances of the same entity.

So, the commonality is that a single entity table is required to represent the entity in each case, with the differences in the relationship cardinality and structure determining how the entity table is designed and linked to itself.

First, we need to calculate the daily interest rate on the credit card. We can do this by dividing the annual percentage rate (APR) by the number of days in a year:

Daily interest rate = APR / 365

Daily interest rate = 0.2445 / 365

Daily interest rate = 0.00067 or 0.067%

Next, we can calculate the interest that will accrue over the course of one month, which is approximately 30 days:

Interest = Balance * Daily interest rate * Number of days

Interest = $1,359 * 0.00067 * 30

Interest = $27.42

Adding the interest to the outstanding balance, we get:

Balance after one month = $1,359 + $27.42

Balance after one month = $1,386.42

Therefore, the balance on the credit card after one month will be approximately $1,386.42.

The expression for the total number of seats in the center section is 12c² +29c - 8

From the question, we are to determine the expression for the total number of seats in the center section

From the given information,

The theater has a center seating section with 3c + 8 rows and 4c - 1 seats in each row

The number of seats in the center section is the product of 3c + 8 and 4c - 1

Thus,

Number of seats in the center section = (3c + 8)(4c -1)

Number of seats in the center section = 12c² - 3c + 32c - 8

Number of seats in the center section = 12c² +29c - 8

Hence, the expression for the total number of seats in the center section is 12c² +29c - 8
