Let the question be,

A group of friends raised money for a charity by selling 11 packs of cookies. They sold a total of 546 cookies. How many 11-packs of cookies did they sell?

The act of charity is the selfless, voluntary assistance provided to those in need as a humanitarian act. There are several charitable ideologies, many of which are religious in nature.

In this problem, we can find the number of 11-packs of cookies by dividing the total number of cookies by the number of cookies in each pack.

We know that:

The number of 11 cookies pack can be determined by:

546 cookies / 11 cookies/pack = 49.63636...

So the number of packs of cookies is 49. This means that 49 is the number that has 11 as a factor.

We can see that:

Part A: 3 appointments

Part B: 5 appointments

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.

Part A

Let x = number of dog grooming appointments Macy had in one day.

Given information:

Charge per appointment = $60

Total amount earned = $220

Total amount of tips earned = $40

Create an equation with the given information:

⇒ 60x + 40 = 220

Solving the equation:

Subtracting 40 from bothsides, we have:

⇒ 60x + 40 - 40 = 220 - 40

⇒ 60x = 180

⇒ 60x ÷ 60 = 180 ÷ 60

⇒ x = 3 appointments.

Part B

Let x = number of dog grooming appointments Logan had.

Given information:

Charge per appointment = $70

Total amount earned = $300

Total amount of tips earned = $50

Rental fee per appointment = $20

Create an equation with the given information:

⇒ 70x - 20x + 50 = 300

Solve the equation:

⇒ 50x + 50 = 300

⇒ 50x + 50 - 50 = 300 - 50

⇒ 50x = 250

⇒ 50x ÷ 50 = 250 ÷ 50

⇒ x = 5 appointments.

Amber and Jeica go out for lunch. Amber’ lunch cot $11. 70, and he tip 18%. Jeica’ lunch cot $12. 30, and he tip 15%, then the percentage of tip is = 33.9%

Define Percentage :

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means.

Given that the Amber’ lunch cot is $11.70.

There is a 18% tax.

Therefore the tax on $11.70 is,

= $11.70×18%

= $2.106

The Amber’ lunch cot with tax is $(11.70 + 2.106)

= $13.806.

The Jeica’ lunch cot is $12.30.

There is a 15% tax.

Therefore the tax on $12.30 is,

= $12.30×15%

= $1.845

The Amber’ lunch cot with tax is $(12.30 + 1.845)

= $14.145.

The tip that is given is $(14.145 - 13.806)

= $0.339

The percentage of tip is

= $0.339 * 100

= 33.9%

Therefore,

Amber and Jeica go out for lunch. Amber’ lunch cot $11. 70, and he tip 18%. Jeica’ lunch cot $12. 30, and he tip 15%, then the percentage of tip is = 33.9%

The rectangle has a length of 222 feet and a width of 150 feet.

A quadrilateral with parallel sides equal to one another and four equal vertices is known as a rectangle. It is also known as an equiangular quadrilateral for this reason.

Rectangles can also be referred to as parallelograms since their opposite sides are equal and parallel.

We know that the perimeter of a rectangle is the sum of all four sides. So in this case:

Perimeter = 2(length) + 2(width)

Given that the perimeter is 446 feet, we can set up the equation:

446 = 2(13x-1) + 2(9x+4)

On Simplifying, we get:

446 = 44x + 6

Now we can solve for x by subtracting 6 from both sides:

440 = 44x

Finally, dividing both sides by 44:

x = 10 feet

Now that we know the value of x, we can substitute it back into the expressions for the length and width:

Length = (13x-1) = (13(10)-1) = 129 feet

Width = (9x+4) = (9(10)+4) = 94 feet

Therefore, the rectangle has a length of 129 feet and a width of 94 feet.

A bijective function is a function that is both one-to-one and onto, meaning that it assigns a unique output to each input, and every output in the codomain is assigned by some input in the domain.

If A has N elements and B has M elements, and we want to find the number of possible bijective functions from A to B, we can use the following formula:

Number of bijective functions = (Number of functions from A to B) / (Number of one-to-one functions from A to B)

The number of functions from A to B is given by the number of ways to assign each element of set A to set B, which is [tex]M^N[/tex].

The number of one-to-one functions from A to B is given by the number of ways to assign a unique element from set B to set A, which is[tex]M!/(M-N)![/tex]

An ordered pair is a set of two values, (x,y), that represents a point on a coordinate plane. To solve an ordered pair means to find the coordinates (x,y) of a point on a coordinate plane.

To solve two ordered pairs, you would need to know the coordinates of both points, and then you can graph them on a coordinate plane to visualize the relationship between the two points.

For example, if you have the ordered pairs (2,3) and (4,5), you can graph them on a coordinate plane with the x-axis and y-axis, where x represents the horizontal position and y represents the vertical position. The point (2,3) would be located at 2 on the x-axis and 3 on the y-axis, and the point (4,5) would be located at 4 on the x-axis and 5 on the y-axis.

Once you have plotted the points on a coordinate plane, you can use them to make a conclusion about the relationship between the two points, for example if they are in the same line, if the distance between them, if they form a slope, etc.

Let a be the amount of 30% copper alloy and b be the amount of 60% copper alloys. The combined alloys must be 50 kilograms.

a + b = 50 kg

The total copper in the mixture:

0.30a + 0.60b = 0.48(50)

Substitute by making use of the first equation

0.30(50-b) + 0.60b = 24

0.30b= 9

Divide both side by 0.30b

b = 9/0.30

b = 30

The amount of 30% copper alloy needed is:

a= 50-b

We know that the total calories she ate for 5 days was 9000 and the number of calories for breakfast is 2500.

The number of calories for dinner over 5 days is 9000 - 2500 = 6500 calories.

To find the average number of calories Tonia consumed for dinner each day over the 5 days, we need to divide the total number of calories for dinner by the number of days:
