We can estimate that after 5 years, there will be approximately 215 stores remaining.

Assuming a 5% decline in the number of stores each year, the function to approximate the total number of stores remaining after x years is exponential, and can be written in the form:

g(x) = a *[tex](0.95)^x[/tex]

where g(x) is the total number of stores remaining after x years, and a is the initial number of stores (278 in this case).

Therefore, the equation for the function is:

g(x) = 278 * [tex](0.95)^x[/tex]

This function takes into account the compounding effect of the 5% decline each year on the initial number of stores and can be used to estimate the number of stores that will remain after any number of years. For example, after 5 years, the number of stores would be approximate:

g(5) = 278 *[tex](0.95)^5[/tex]

g(5) ≈ 214.5

Therefore, we can estimate that after 5 years, there will be approximately 215 stores remaining.

There are 4060 different groups of 3 pictures that can be displayed on the frame.

A combination is a method of choosing a subset of items from a bigger set when the order of the items is irrelevant. For instance, the two-letter possibilities for a set of three letters A, B, and C are AB, AC, and BC. Combinations are employed in many different mathematical and practical situations, including combinatorial optimization, statistics, and probability theory. Choosing a password with a specific amount of characters, picking a combination of things from a menu, and assembling a team from a group of players are all examples of how they are utilised in daily life.

Given that, from 30 pictures we need to form groups of 3.

The combination of selecting groups is given as:

nCk = n! / (k! * (n - k)!)

Substituting the values we have:

30C3 = 30! / (3! * (30 - 3)!)

= 30! / (3! * 27!)

= (30 * 29 * 28) / (3 * 2 * 1)

1)  5/8 × 2 1/2 is slightly more than 1/4. Therefore, the correct option is:

C.

2) The area of the fortune cookie is: B. 1 25/16 square inches.

In mathematics, area is the measure of the size or extent of a two-dimensional shape or surface, such as a rectangle, triangle, circle, or any other closed figure. It is the amount of space inside the boundary of a shape, usually measured in square units.

For example, the area of a rectangle can be found by multiplying its length and width. The formula is:

Area = length × width

The area of a circle can be found by multiplying the square of its radius by pi (π). The formula is:

Area = πr²

where r is the radius of the circle.

Part A:

To estimate whether 5/8 × 2 1/2 is more or less than 1/4, we can round 5/8 to 1/2 and round 2 1/2 to 2. Then we have:

1/2 × 2 = 1

So, 5/8 × 2 1/2 is slightly more than 1/4. Therefore, the correct option is:

C. 5/8 × 2 1/2 is more than 1/4.

Part B:

The area of the fortune cookie can be found by multiplying its length by its height. The length is given as 2 1/2, which can be written as an improper fraction:

2 1/2 = 5/2

The height is given as 5/8. So, the area can be devised as:

Area = length × height

Area = (5/2) × (5/8)

Area = 25/16

Therefore, the area of the fortune cookie is:

B. 1 25/16 square inches.

The equations that arise when the steps of the Euclidean algorithm are reversed to express the greatest common divisor of each of these pairs of integers as a linear combination of these integers are:

1 = 10 - 3.3, 1 = 37.10 - 3.123, and 1 = 37.2347-706 - 123.

The Euclidean algorithm is a recursive method for finding the greatest common divisor (GCD) of two positive integers. When we divide the larger number by the smaller number, we obtain the remainder. The smaller number and the remainder are then passed on as input to the next round. The process continues until the remainder is zero, at which point the GCD is obtained.

The solution to the given problem is as follows:

We will use the Euclidean algorithm to compute gcd(123, 2347).

123 ÷ 2347 = 0 remainder 123.2347 ÷ 123 = 19 remainder 106.123 ÷ 106 = 1 remainder 17.106 ÷ 17 = 6 remainder 4.17 ÷ 4 = 4 remainder 1.4 ÷ 1 = 4 remainder 0.The last nonzero remainder we get is 1.

Therefore, the greatest common divisor (GCD)(123, 2347) = 1.

The greatest common divisor of 123 and 2347 can be expressed as a linear combination of the two numbers in the following ways:1 = 10 - 3.3, 1 = 37.10 - 3.123, and 1 = 37.2347-706 - 123.

Answer:

To sketch the given region on the Argand diagram, we need to find the intersection of the three conditions:

-3i < Im(z) < 3i (the imaginary part of z lies between -3 and 3 on the vertical axis)

1 < Re(z) ≤ 6 (the real part of z lies between 1 and 6 on the horizontal axis)

|z - 4| ≥ 1 (the distance between z and 4 is greater than or equal to 1, which means z is outside or on the boundary of the circle centered at 4 with radius 1)

The first two conditions define a rectangle in the complex plane with vertices at (1,-3i), (1,3i), (6,3i), and (6,-3i). The third condition excludes the inside of a circle centered at 4 with radius 1, which means the region we want is the rectangle with a circular hole in the middle.

To find the area of this region, we can subtract the area of the circle from the area of the rectangle. The area of the rectangle is:

A_rect = length x width = (6 - 1) x (3i - (-3i)) = 30i

The area of the circle is:

A_circle = πr^2 = π(1)^2 = π

Therefore, the area of the region is:

A_region = A_rect - A_circle = 30i - π

So the area of the region is 30i - π, written in terms of π.

Answer:42.06

Step-by-step explanation:

The distance Mrs. Smith covers is 3520 yards during the duration of the week by Friday morning.

One week has seven days in total.

Mrs. Smith walks half a mile each day after work, she walks a total of

0.5 miles/ day × 7 days/ week = 3.5 miles/ week

Now, if we calculate the distance on Friday morning, she must have walked four times till Friday morning since she has to walk after her work.

Therefore,

0.5 miles/ day × 4 days = 2 miles

To convert miles to yards, we can use the fact that there are 1760 yards in one mile:

2 miles/week × 1760 yards/mile = 3520 yards/week

To solve for y, we need to isolate the variable y on one side of the equation. We can do this by multiplying both sides by 8:

-24 x 8 = y

Simplifying the left side:

-192 = y

Therefore, the solution is y = -192.

Answer: 9, 10, and 11

Step-by-step explanation:

If the sum of three consecutive natural numbers is 30, then we can represent the smallest of the three numbers as x. The next two consecutive natural numbers would be x+1 and x+2. Therefore, we can form the equation:

x + (x+1) + (x+2) = 30

Simplifying the left-hand side, we get:

3x + 3 = 30

Subtracting 3 from both sides, we get:

3x = 27

Dividing by 3, we get:

x = 9

Therefore, the three consecutive natural numbers are 9, 10, and 11.

b) The maximum profit of $5200 achieved.

Selling profit is the profit that a business makes on the sale of its products or services. It is the difference between the selling price and the cost of product.

a) Let x be the number of boards of mahogany sold and y be the number of boards of black walnut sold. Then, the constraints of the problem can be represented by the following system of inequalities:

x ≥ 0 (non-negative constraint)

y ≥ 0 (non-negative constraint)

x ≤ 260 (maximum number of mahogany boards available)

y ≤ 320 (maximum number of black walnut boards available)

x + y ≤ 380 (maximum number of boards that can be sold)

To graph this system of inequalities, we can plot the lines x = 0, y = 0, x = 260, y = 320, and x + y = 380 on a coordinate plane and shade the feasible region that satisfies all of the constraints. The feasible region is the area that is bounded by these lines and includes the origin (0, 0).

b) The profit function P(x, y) can be defined as follows:

P(x, y) = 20x + 6y

To maximize the profit, we need to find the values of x and y that satisfy all of the constraints and maximize the profit function P(x, y).

One way to do this is to use the corner-point method. We can evaluate the profit function at each of the corners of the feasible region and find the corner that gives the maximum profit.

The corners of the feasible region are (0, 0), (0, 320), (260, 0), and (120, 260).

P(0, 0) = 0

P(0, 320) = 6(320) = 1920

P(260, 0) = 20(260) = 5200

P(120, 260) = 20(120) + 6(260) = 4720

Therefore, the maximum profit of $5200 can be achieved by selling 260 boards of mahogany and 0 boards of black walnut.

Answer:

To use an area model to determine the quotient of 556 and 16, we can divide a rectangle of area 556 into 16 equal parts. Each part will have an area of 556/16.

We can start by dividing 556 into 16 groups of 10 (160), and then into 16 groups of 3 (48). That leaves us with a remainder of 4.

So we have:

556 = 16 x 34 + 48 + 4

This shows that 556 can be written as 16 times some whole number (34) plus a remainder of 48 + 4/16.

Simplifying the remainder, we have:

48 + 4/16 = 48 + 1/4 = 48.25

Therefore, the quotient of 556 and 16 is:

556/16 = 34 1/4

The quotient of 556 and 16 using an area model can be determined by producing a rectangle with the total area of 556 and one side of 16. The length of the other side will be the quotient. In this case, the quotient is 34 3/4.

When asked to determine the quotient of 556 and 16 using the area model, one way to think of this is making a rectangle. The total area is 556 and one side is 16. The length of the other side will be the quotient.

Start by first estimating how many times 16 could fit into 556. Let's take 30 as an estimate, because 30*16 = 480, which is relatively close to 556. Draw a rectangle with the width of 16 and the length of 30.

Find the difference between the rectangle's area and 556. So, 556 - 480 = 76. Now, 76 is our remaining area to fill. 16 goes into 76 four more times, adding up to 64.

There is still a leftover area, which is 76-64 = 12. This is smaller than our width of 16. So, your final answer is 34 12/16 or 34 3/4 in simplest form.
