To make 6 dozen cookies, you will need 2 1/2 cups of flour.

To find out how many cups of flour are needed to make 6 dozen cookies, we can set up a proportion:

1 2/3 cups / 4 dozen cookies = x cups / 6 dozen cookies

Cross multiplying, we get:

4 dozen cookies * x cups = 1 2/3 cups * 6 dozen cookies

Simplifying, we find that x cups = (1 2/3 cups * 6 dozen cookies) / 4 dozen cookies

Therefore, x cups = 2 1/2 cups

Final answer:

To make 6 dozen cookies, you would need 2.5 cups of flour.

Explanation:

To find out how many cups of flour are needed to make 6 dozen cookies, we can set up a proportion using the given information. We know that 1 2/3 cups of flour are needed to make 4 dozen cookies. So we can set up the proportion:

1 2/3 cups / 4 dozen = x cups / 6 dozen

To solve for x, we can cross multiply and then divide:

(1 2/3 cups) * (6 dozen) = (4 dozen) * x cups

(5/3) * (6) = (4) * x

30/3 = 4x

10 = 4x

x = 10/4 = 2.5

Therefore, you would need 2.5 cups of flour to make 6 dozen cookies.

n  = unknown number

5 less than 4 times a number = 4n-5

2 more than 3 times a number = 3n+2

 so you have 4n-5 = 3n +2

add 5 to both sides:

4n=3n+7

subtract 3n from both sides:

n = 7

To find the greatest number of pens or pencils that Louis can place in each bag, we need to find the greatest common divisor (GCD) of 45 and 75. Using the Euclidean algorithm, the GCD is determined to be 15.

In order to find the greatest number of pens or pencils that Louis can place in each bag, we need to find the greatest common divisor (GCD) of the given numbers, 45 and 75. The GCD represents the largest number that can evenly divide both 45 and 75.

We can find the GCD by using the Euclidean algorithm. Starting with the larger number (75), we divide it by the smaller number (45) and find the remainder (30). Then, we divide the divisor (45) by the remainder (30) and find the new remainder (15). We continue this process until we reach a remainder of 0. The last non-zero remainder (15) is the GCD of 45 and 75.

Therefore, the greatest number of pens or pencils that Louis can place in each bag is 15.

Final answer:

An obtuse angle is one measuring between 90 and 180 degrees. Without a diagram, one cannot name a specific obtuse angle with vertex 'n', but generally, any angle appearing to open wider than 90 degrees at vertex 'n' can be considered obtuse.

Explanation:

To determine an angle with a vertex named 'n' that is obtuse, you need to know that an obtuse angle is one that measures more than 90 degrees but less than 180 degrees. Unfortunately, without a diagram or more context, it's impossible to provide a specific example. However, if you're looking at a diagram where an angle is labeled with the vertex 'n', and you can see that the angle opens wider than a right angle (which is exactly 90 degrees), then that angle is likely obtuse.

For instance, let's consider an angle named angle XnY, where 'n' is the vertex or corner point. If the measure of angle XnY is say, 120 degrees, it is definitively an obtuse angle because it falls between 90 and 180 degrees. The notation for an obtuse angle with vertex 'n' could be written as angle XnY (where 'X' and 'Y' stand for the names of the other points that form the angle with vertex 'n').

Any angle with its vertex at point "n" that measures more than 90 degrees and less than 180 degrees would be considered an obtuse angle.

An angle is a measure of the amount of rotation needed to bring one line or plane into coincidence with another, generally measured in degrees or radians.

An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. Therefore, any angle with its vertex at point "n" that measures more than 90 degrees and less than 180 degrees would be considered an obtuse angle. An example of such an angle could be ∠ABC, where point B is the vertex and the angle measures, for instance, 120 degrees.

[tex]\(4.56 \times 10^3\) bulbs/week. After \(9.36 \times 10^2\)[/tex] weeks, approximately [tex]\(4.27 \times 10^6\)[/tex] bulbs produced.

To find the total number of light bulbs the company will produce in [tex]\(9.36 \times 10^2\)[/tex] weeks, you multiply the number of light bulbs produced each week by the number of weeks:

[tex]\[(4.56 \times 10^3) \times (9.36 \times 10^2)\][/tex]

When you multiply numbers in scientific notation, you multiply the coefficients and add the exponents. So:

[tex]\[(4.56 \times 10^3) \times (9.36 \times 10^2) = (4.56 \times 9.36) \times (10^3 \times 10^2)\]\[= 42.6816 \times 10^{3+2}\]\[= 42.6816 \times 10^5\][/tex]

Now, we rewrite [tex]\(42.6816\)[/tex] in scientific notation:

[tex]\[42.6816 = 4.26816 \times 10^1\][/tex]

So, the total number of light bulbs the company will produce is:

[tex]\[4.26816 \times 10^1 \times 10^5 = 4.26816 \times 10^{1+5} = 4.26816 \times 10^6\][/tex]

In scientific notation, the best estimate of the number of light bulbs the company will make in [tex]\(9.36 \times 10^2\) weeks is \(4.27 \times 10^6\).[/tex]

A man borrowed $500 at a 12% annual interest rate and repaid it after 18 months. The calculated simple interest on the loan is $6.00.

To calculate simple interest, you can use the formula:

Simple Interest = [tex]\frac{P \times R \times T}{100}[/tex]

where:

- P is the principal amount (the initial amount borrowed),

- R is the rate of interest per annum, and

- T is the time the money is borrowed for in years.

In this case:

- P = $500,

- R = 12%(or 0.12 as a decimal), and

- T = 18 months (which is 1.5 years since [tex]\( \frac{18}{12} = 1.5 \))[/tex].

Now plug these values into the formula:

Simple Interest = [tex]\frac{500 \times 0.12 \times 1.5}{100}[/tex]

Calculate this expression to find the simple interest.

Simple Interest = [tex]\frac{500 \times 0.12 \times 1.5}{100}[/tex]

Simple Interest = [tex]\frac{90}{100}[/tex]

Simple Interest = $6.00

Therefore, the simple interest on a $500 loan at an annual interest rate of 12% over 18 months is $6.00.

The complete question is:

A man borrows $500 and pays it back after 18 months at 12% per annum. Find the simple interest.

The simple interest is $90.

The formula for simple interest is:

I = PRT

Where:

I = the interest paid

P = the principal amount borrowed

R = the interest rate

T = the time period (in years)

We know that P = $500, R = 12% = 0.12, and T = 18 months = 18/12 = 1.5 years. We can now plug these values into the formula to solve for I:

I = $500 * 0.12 * 1.5 = $90

Therefore, the simple interest is $90.

To find the total cost, we must multiply the amount that was bought by the price of each individual item. So we need to multiply the price of one gallon by how many gallons Tina bought:

[tex] 15.25*2.31=35.227 [/tex]

However, the question says to round to the nearest hundredth, so we must round up. Therefore the total amount Tina paid for the gasoline was $35.23.

If Tina bought 15.25 gallons of gasoline at a price of $2.31 per gallon. The total cost of the gasoline rounded to the nearest hundred will be: $35.23

Using this formula

Total cost=Quantity ×price

Where:

Quantity=15.25 gallons

Price=$2.31 per gallon

Let plug in the formula

Total cost=15.25×$2.31

Total cost=$35.2275

Total cost=$35.23 (Approximately)

Inconclusion if Tina bought 15.25 gallons of gasoline at a price of $2.31 per gallon. The total cost of the gasoline rounded to the nearest hundred will be: $35.23

The commutative property of addition allows us to rearrange the order of terms without changing the sum. Demonstrating this property makes simplifying expressions easier by rearranging terms.

The commutative property of addition states that changing the order of the numbers being added does not change the sum. In the expression (-3 + i) + (18 + 5i), we can demonstrate the use of the commutative property in the first step by rearranging the terms as (-3 + 18) + (i + 5i).

Simplifying further, we get 15 + 6i as the result after applying the commutative property of addition.
