The clerk did not give Mary any change, so that is the correct response.

A price decrease from the normal or list amount or a proportional deduction from such a debt account, typically applied in exchange for on-time or cash payments.

The total cost of the shirt and three skirts before the coupon is:

$22.65 + 3($33.31) = $122.58

With the 10% discount, the total cost becomes:

$122.58 - 0.1($122.58) = $110.32

To find out how much change the cashier gave back to Mary, we need to subtract the total cost from the amount of money Mary's mom gave her:

$100.00 - $110.32 = -$10.32

Since the result is negative, it means Mary did not have enough money to pay for her purchases and would have to give the cashier an additional $10.32 to cover the full cost of her shopping.

Therefore, the answer is that Mary did not receive any change from the cashier.

The width of the rectangular prism shaped toolbox is 10 inches.

A prism is a three-dimensional geometric shape that has two parallel and congruent bases that are connected by a set of parallelograms or rectangles. A prism is named according to the shape of its base, such as triangular prism, rectangular prism, or hexagonal prism.

A prism is characterized by its length, width, and height, and it has a volume equal to the product of its base area and its height. The lateral faces of a prism are parallelograms or rectangles, and the edges of a prism where the lateral faces meet the bases are perpendicular to the bases.

Now,

To find the width of the toolbox, we can use the formula for the volume of a rectangular prism, which is:

Volume = length x width x height

We are given that the volume of the toolbox is 4,500 cubic inches, the length is 30 inches, and the height is 15 inches.

Then

4,500 = 30 x width x 15

Simplifying the right side, we get:

4,500 = 450 * width

Dividing both sides by 450, we get:

width = 10 inches

Therefore, the width of the toolbox is 10 inches.

From the given situation of equation Diamond worked 24 overtime hours that week.

The hourly rate that is paid for the typical hours worked within a pay period is known as regular pay. For full-time employees in the US, this is typically referred to as 40 hours a week. On the other hand, overtime pay is the hourly rate paid for any additional hours worked. Most businesses give time-and-a-half (1.5 times the usual pay rate) or double-time (two times the regular pay rate) for extra hours, which is often more than regular compensation.

Let us suppose the number of hours = x.

Let us suppose the overtime hours = y.

From the given situation we have:

7.5x + 11.25y = 352.5 (equation 1)

x + y = 35 (equation 2)

Substituting equation 2 into equation 1 and simplifying:

7.5x + 11.25(35 - x) = 352.5

7.5x + 393.75 - 11.25x = 352.5

Natural numbers are a set of positive integers that are used for counting and ordering. In other words, natural numbers are the set of numbers that are used to represent the quantity of objects, such as 1, 2, 3, 4, 5, 6, and so on. Some definitions include zero as a natural number, while others define natural numbers to start from 1. In mathematics, natural numbers are denoted by the symbol "N" or "N+", and are sometimes referred to as counting numbers.

Whole numbers are a set of non-negative integers that include all natural numbers (positive integers) and zero. Whole numbers are used to represent quantities that cannot be divided into smaller parts, such as the number of people in a room, the number of apples in a basket, or the number of books on a shelf.

In the given question,

We know that 105 is a multiple of 3, 5, and 7. Therefore, if 3^x+5^y+7^z is divisible by 105, it must also be divisible by 3, 5, and 7.

If 3^x+5^y+7^z is divisible by 3, then 3^x ≡ 0 (mod 3), which means x ≥ 1.

If 3^x+5^y+7^z is divisible by 5, then 5^y ≡ 0 (mod 5), which means y ≥ 1.

If 3^x+5^y+7^z is divisible by 7, then 7^z ≡ 0 (mod 7), which means z ≥ 1.

Therefore, we have x+y+z ≥ 3.

We also know that 105 is the smallest multiple of 3, 5, and 7. Therefore, we want to find the smallest values of x, y, and z that will make 3^x+5^y+7^z divisible by 105.

If we want 3^x+5^y+7^z to be divisible by 105, we need x, y, and z to be multiples of 4, 4, and 3, respectively.

The smallest such values are x=4, y=4, and z=3. Therefore, the smallest possible value of x+y+z is 4+4+3=11.

You should add 115.2 fluid ounces of oil to your 1.5 quarts of gasoline.

An expression is a group of symbols and/or numbers used to represent a quantity or a mathematical relationship between two quantities in mathematics. Variables, constants, as well as operators like addition, subtraction, multiplication, and division, can all be found in an expression.

Since there are 4 quarts in a gallon, 1.5 quarts is equal to 1.5/4 = 0.375 gallons of gasoline.

To determine how much oil to add, we need to use the ratio of 2.4 fl. oz. of oil for every gallon of gasoline.

First, we need to convert the amount of gasoline we have from gallons to fluid ounces:

0.375 gallons x 128 fluid ounces per gallon = 48 fluid ounces of gasoline.

Next, we can use the ratio to find how much oil to add:

2.4 fl. oz. oil: 1 gallon gasoline

x fl. oz. oil: 48 fl. oz. gasoline

Cross-multiplying, we get:

2.4 x 48 = 1 x (x)

115.2 = x

So you should add 115.2 fluid ounces of oil to your 1.5 quarts of gasoline.

If the original triangle has an area equal to 729 small dotty triangles. The original triangle has an area of 8 square units.

Let's first find the pattern of the number of small triangles in each row. The first row has 1 small triangle. The second row has 3 small triangles. The third row has 5 small triangles, and the fourth row has 7 small triangles. We can see that the pattern is that each row has 2 more small triangles than the previous row.

To find how many small triangles are in the third row, we add 2 to the number of small triangles in the second row:

3 + 2 = 5

So there are 5 small triangles in the third row.

To find how many small triangles are in the fourth row, we add 2 to the number of small triangles in the third row:

5 + 2 = 7

So there are 7 small triangles in the fourth row.

To find the total number of rows, we can count the number of rows from the top of the triangle to the bottom. Alternatively, we can use the formula for the sum of an arithmetic series to find the number of terms in the sequence. In this case, the first term is 1, the common difference is 2, and the last term is 7. Using the formula:

n = (last term - first term) / common difference + 1

n = (7 - 1) / 2 + 1

n = 4

So there are 4 rows in the triangle.

Finally, we can use the formula for the sum of an arithmetic series to find the total number of small triangles in the original triangle. In this case, the first term is 1, the common difference is 2, and the number of terms is 4. Using the formula:

sum = (n / 2) * (first term + last term)

sum = (4 / 2) * (1 + 7)

sum = 4 * 4

sum = 16

So there are 16 small triangles in the original triangle. Since each small triangle has an area of 1/2, the total area of the original triangle is:

area = 16 * (1/2)

area = 8

Therefore, the original triangle has an area of 8 square units.

The ratio for the area and the ratio for the circumferences of the circles are 9 : 1 and 6 : 1 respectively.

What is a circle?

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the centre.

If the radius of one circle is three times the radius of another circle, then we can use this information to determine the ratio of the areas of the circles and the ratio of the circumferences of the circles without knowing their actual measurements.

Let's call the radius of the smaller circle "r" and the radius of the larger circle "3r".

Ratio of areas -

The area of a circle is proportional to the square of its radius, so the ratio of the areas of the two circles is -

= (area of larger circle) / (area of smaller circle)

= (π(3r)²) / (πr²)

= 9r²/r²

= 9/1

Therefore, the ratio of the areas of the two circles is 9:1.

Ratio of circumferences -

The circumference of a circle is proportional to its radius, so the ratio of the circumferences of the two circles is -

= (circumference of larger circle) / (circumference of smaller circle)

= 2π(3r) / 2πr

= 6r/r

= 6/1

Therefore, the ratio of the circumferences of the two circles is 6:1.

Answer: C

Step-by-step explanation:

The equation of the line that represents the total cost is c = 4d + 8 and the total cost when 1 drink is bought is $ 12.

The slope-intercept form of a line has used to form a linear equation in two variables. It is called the slope-intercept form because it gives us two pieces of information about the line its slope and y-intercept.

The slope-intercept form of a line is given by the equation:

where:

m is the slope of the line

b is the y-intercept of the line

Here we have

The graph shows the total cost c of buying one large bucket of popcorn and d large drinks.  

From the graph, the line passes through points (0, 8) and (1, 12)  

Hence, slope of the line (m) = [(y₂ - y₁) / (x₂ - x₁) ]

= [(12 - 8) / (1 - 0) ] = [4 / 1] = 4

Let y = mx + c be the lines

=> y = 4x + c

Since the line passes through (0, 8)

=> 8 = 4(0) + c

=> c = 8

Hence, the required equation is y = 4x + 8  

From the data,

The y-axis represents the total cost 'c' and the x-axis represents the number of drinks 'd'

=>  Total cost c = 4d + 8

Hence,

The equation of the line that represents the total cost is c = 4d + 8

If we bought 1 large drink

=> c = 4(1) + 8 = 12

Therefore,

The equation of the line that represents the total cost is c = 4d + 8 and the total cost when 1 drink is bought is $ 12.

The required slope of the tangent line to the graph of the function at the point (-1, 5) is -2.

A line that only touches a circle or an ellipse at one place is said to be tangential in geometry. If a line touches a curve at point P, that place is referred to as the point of tangency. In other words, it is described as the line that, at that particular point, depicts the slope of a curve.

The slope of the tangent line to the graph of a function at a given point is equal to the derivative of the function at that point.

So, to find the slope of the tangent line to the graph of the function f(x) = -2x at the point (-1, 5), we need to find the derivative of the function at x = -1.

Using the power rule for derivatives, we can find the derivative of f(x) = -2x as:

Therefore , the solution of the given problem of square comes out to be the square's perimeter is higher than the number of square units for the square's surface.

A square, according to Euclidean mathematics, is a quadrilateral with four equal sides and four equal angles. Another term for a rectangle is a shape with two neighboring sides that are the same length. A quadrilateral is said to be equilateral if one of its 4 triangular edges and four equal corners is a square. A cubical angle refers to one that's 90 ° or straight. The square's diagonals are evenly spaced and split in half at a 90-degree angle.

Here,

We can use the formulas for area and perimeter of a square to decide which is greater: its area or perimeter with sides that are 10 units long.

A = s², where s is the extent of one edge, calculates the area of a square. The square's size in this instance is

=> 102 = 100 square units.

P = 4s, where s is the length of one edge, calculates the perimeter of a square. In this instance, the square's circumference is

=> 4(10)

=> 40 units.

We can see that the perimeter is larger than the area by comparing the two values.

Consequently, we can draw the conclusion that the number of units for the square's perimeter is higher than the number of square units for the square's surface.

The combination of numerical variables and operations expressed by the addition, subtraction, multiplication, and division signs is known as a mathematical expression.

Given is that the starting balance is 62. As a result, the sum rises by 4%.

The time period is 12, but he will pay for 11 extra months, not including the first month's 62 dollars.

The formula is: y=62(1+0.11

y=62(1.04) ^11

The amount to be paid in the previous month is: y=95.45$

This geometric sequence has r equal to 1.04 in this case. The total will be determined as follows:

Sum = 62(1.04¹¹-1)/1.04-1

Sum = $836

Hence, $836 will be paid in total throughout the first 12 months.
