On solving the provided question, we can say that by permutation, 90  different 8-topping pizzas are possible

The permutation of a set in mathematics is essentially the rearranging of its elements if the set is already ordered, or the arrangement of its members in a linear or sequential order. The act of altering the linear order of an ordered set is referred to as a "permutation" in this context. The mathematical calculation of the number of possible arrangements for a given set is known as permutation. Permutation, in its simplest form, refers to the variety of possible arrangements or orders. The placement of the elements matters with permutations. The placement of items in a specific order is known as a permutation. Here, the set's components are sorted in either chronological order or linear order.

The system of equations 2x + y = 40 and x - 2y = -20 has a solution of x = 12 and y = 16. We can solve this system by using the method of substitution or elimination.

One way to solve the system is to use the method of substitution. We can first solve one of the equations for one of the variables and substitute that expression into the other equation.

For example, we can solve the first equation for y by isolating y on one side: y = 40 - 2x. Then we can substitute that expression into the second equation and solve for x:

x - 2(40 - 2x) = -20

x - 80 + 4x = -20

5x = 60

x = 12

Then we can substitute x = 12 into the first equation, or either equation to find the value of y:

2(12) + y = 40

y = 16

So the solution to the system of equations is x = 12 and y = 16.

Another way to solve the system of equations is to use the method of elimination. This involves adding or subtracting the equations to eliminate one of the variables. For example, we can add the equations and get:

3x - y = 20

Then we can solve for x or y and substitute it back into either of the equation to find the other variable.

The table represents a function. X y 0 6 2 8 4 10 6 12 complete the statement by selecting from the drop-down menu. The rate of change in the function y = x + 4 is  equal to the rate of change of the function represented in the table.

Consider the function shown in the table.

The table's coordinates are as follows:

(0,6) (2,8) (4,10) and (6,12) (6,12)

Take into account the first two coordinates (0, 6) and (2,8)

x₁=0, y₁=6, x₂=2, y₂=8

Linear equation is provided by (y-y₁) =m(x-x₁)

Where 'm' is the slope (rate of change), the following formula is used:

m = y₂ - y₁

      x₂ - x₁

So,

m = 8 - 6 = 1

      2 - 0

So, the line's equation is:

(y-6)= 1 (x-0) (x-0)

y-6=x

y=x+6

Putting it up against the common equation of the line y=mx+c with slope "m."

Thus, m(Rate of Change)=1 is obtained.

Now,

We will calculate the slope for the function y=x+4

Putting it up against the common equation of the line y=mx+c with slope "m."

Thus, m(Rate of Change)=1 is obtained.

Answer: To solve this problem, we can use the law of cosines. The law of cosines is a useful tool for solving problems involving distances and angles between points in two-dimensional space. We can use the law of cosines to find the distance between the starting and ending point of the hike, and the bearing to get back to camp.

The law of cosines states that:

c^2 = a^2 + b^2 - 2ab * cos C

where c is the distance between the two points, a and b are the distances of the two legs of the hike, and C is the angle between them.

Using the given information, we can set a as the distance traveled at 3.5 miles per hour for 2 hours, which is 3.5 * 2 = 7 miles,

b as the distance traveled at 3.5 miles per hour for 4 hours which is 3.5 * 4 = 14 miles,

C as the angle between the two legs of the hike which is (72 + 23) = 95 degrees.

Now we can substitute this values into the law of cosines formula:

c^2 = 7^2 + 14^2 - 2(7)(14) * cos 95

Solving this equation will give us the square of the distance between the starting and ending point of the hike. To find the actual distance, we'll have to take the square root of that.

The distance directly back to camp is √(196 - 98*(√2/2)) = √(196 - 98*(√2/2)) ≈ 8.14 miles

To find the bearing to head back to camp, we must know that the bearing of a line is defined as the angle between the line and the North direction, measured clockwise.

We can use the bearing of N72°W and S23°W to find the back bearing to camp.

The back bearing is (180 + 72 + 23) = 275 degrees. The hikers should take a bearing of 275 degrees to head back to camp.

Step-by-step explanation:

[tex]\dfrac{2}{3} (n-6)=5n-43[/tex]

Distribute:

[tex](\dfrac{2}{3} )(n)+(\dfrac{2}{3} )(-6)=5n-43[/tex]

Subtract 5n from both sides:

A quadratic inequality is an inequality that can be written in the form of "ax² + bx + c < or > 0" where a, b and c are real numbers and x is a variable.

The solutions to a quadratic inequality are the values of x that make the inequality true. To solve a quadratic inequality, we first set the expression equal to zero and then find the roots (also known as the zeroes or solutions) of the equation. We then use these roots to divide the number line into three regions: the region where the expression is less than zero, the region where the expression is greater than zero, and the region where the expression is equal to zero.

Two tiles will be left over. Jenny will have two square tiles left over after arranging her tiles into a rectangular array of four rows.

50 quare tiles divided by 4 rows = 12.5 quare tiles

12.5 quare tiles per row x 4 rows = 50 quare tiles

50 quare tiles used - 50 quare tiles = 0 quare tiles

Remaining tiles = 0 quare tiles

50 quare tiles - 0 quare tiles = 50 quare tiles

Left over tiles = 2 quare tiles

Jenny has 50 square tiles which she arranges into a rectangular array of four rows. To work out how many square tiles are left over, first divide 50 by 4. This gives us 12.5 tiles per row, however this is not possible so we need to round this number down to 12. Multiplying 12 by 4 gives us 48 tiles used in the rectangular array. Subtracting the 48 tiles used from the 50 tiles that Jenny had originally gives us a result of 2 square tiles left over. In conclusion, Jenny will have two square tiles left over after arranging her tiles into a rectangular array of four rows.
