The pancakes stall sells total 12 combinations of pancakes.

What is Combination?

Combinations are mathematical operations that count the number of potential permutations for a set of elements when the order of the selection is irrelevant.

According to the given data:

Savory pancakes can have 3 toppings in any combination.

Therefore, total number of savory pancake combinations = 3 x 2 x 1 = 6

For sweet pancakes jams can either have ice cream or fresh cream.

Therefore combinations with ice cream = 3

And combinations with fresh cream = 3

Hence total combinations for sweet pancakes = 3 + 3 = 6

Now, total pancakes combination = 6 + 6 = 12

So, the stall sells 12 combinations of pancakes.

let's recall the vertical line test, if a vertical line hits the graph or points twice, then is NOT a function.  Check the picture below.

A very easy way to find out if a graph is a function is to use the vertical line test.

Look at each graph and mentally draw a vertical line that goes through each of its points.

If that line goes through more than one point (2, 3, 4...) then that graph is not a function.

That's because a function, is an equation for which each input (x value) has exactly one output (y value). There cannot be two points of the same x value, with two different y values.

The coordinates of the point P lying between AB is found as (7, -2/5).

For the given question;

The two end coordinates are;

(x₁, y₁) = (8, 0)

(x₂, y₂) = (3, -2)

The ratio of the division is;

AP/PB = 1/4

OR

m:n = 1:4

The Formula for finding the coordinates of P for internally crossing is;

x = (mx₂ + nx₁)/(m + n)

y = (my₂ + ny₁)/(m + n)

Put the values;

x = (mx₂ + nx₁)/(m + n)

x = (1×3 + 4×8)/(1 + 4)

x = (3 + 32)/5

x = 7

Now for y coordinates.

y = (my₂ + ny₁)/(m + n)

y = (1×(-2) + 4×0)/(1 + 4)

y = -2/5

Thus, the coordinates of the point P lying between AB is found as (7, -2/5).

The figure's perimeter and area would be as follows.

Perimeter = 21.19 cm

Area = 25.501 cm²

A Cartesian coordinate system in some kind of a plane is a system of coordinates that uniquely identifies each point by a pair of numerical coordinates, which are the signed distances from two fixed perpendicular lines that are aligned to the point and are both measured in the same length.

point of the coordinates are as follows:

A(2, 1)

B(8, 6).

C(10, 1)

We know that the formula for finding for the distance is:

d=√((x2 – x1)² + (y2 – y1)²).

For Point AB:

X₁ = 2

Y₁ = 1

X₂ = 8

Y₂ = 6

putting the values onto formula we get:

d=√((x2 – x1)² + (y2 – y1)²).

d=√((8 – 2)² + (6 – 1)²).

d=√((6)² + (5)²).

d=√(36 + 25).

d=√(61).

AB =7.81

For Point BC:

X₁ = 8

Y₁ = 6

X₂ = 10

Y₂ = 1

putting the values onto formula we get:

d=√((x2 – x1)² + (y2 – y1)²).

d=√((10 – 8)² + (1 – 6)²).

d=√((2)² + (-5)²).

d=√(4 + 25).

d=√(29).

BC = 5.38

For Point CA:

X₁ = 10

Y₁ = 1

X₂ = 2

Y₂ = 1

putting the values onto formula we get:

d=√((x2 – x1)² + (y2 – y1)²).

d=√((2 – 10)² + (1 – 1)²).

d=√((-8)² + (0)²).

d=√(64 + 0).

CA = 8

The perimeter of the given figure is:

Sum of all the sides.

AB + BC + CA

7.81 + 5.38 + 8

21.19 cm

Now finding the area of the tringle we use Pythagoras formula:

H² = P² + B²

P² = H²  - B²

P² = (7.81)²  - (5.38)²

P = 9.4837

We know that the area of the triangle is: = 1/2(base * Hight).

                                                                    = 1/2(5.38  * 9.48)

We are looking for the point at which the compensation from Plan A is less than the compensation from Plan B.

Plan A = 850 +0.1x

Plan B= 1050+(x-7000)(0.14)

Plan A < Plan B

850 +0.1x <1050+(x-7000)(0.14)

then we sill simplify

850+0.1x < 1050+0.14x-980

850+0.1x<70+0.14x

then we isolate the x

11 is the greatest number of bags that Jason can fill with equal number of raspberry and blackberry scones.

In this question we have been given Jason has 22 raspberry scones and 55 blackberry scones.

We need to find the maximum number of bags Jason can fill with equal number of raspberry scones and blackberry scones.

We will be using Greatest common factor (GCF) for knowing the number of bags.

22 = 2 × 11

and 55 = 5 × 11

So, the greatest common factor of 22 and 55 is 11

GCF(22, 55) = 11

Therefore, 11 is the greatest number of bags that Jason can fill with equal number of raspberry and blackberry scones.

Step-by-step explanation: Edge

Interior Angle Theorem asserts that the alternate interior angles that result when two parallel lines are cut by a transversal are equivalent.

If m2 + m28 = 180 then we get ∠2 + ∠8 = 180°

Lines that are parallel to one another on a plane do not intersect or meet at any point.  They are always equidistant from one another and parallel. Non-intersecting lines are parallel lines.

Two lines are said to be parallel if a transversal and two matching angles it forms are congruent.

Verification of Parallel Lines

When two lines are intersected by a transversal and the opposing interior angles line up, the intersected lines are said to be parallel. Two lines are said to be parallel if they are divided by a transversal such that their opposing exterior angles are equivalent.

Therefore,

Given line m is parallel to line m

Interior Angle Theorem asserts that the alternate interior angles that result when two parallel lines are cut by a transversal are equivalent.

Alternate Exterior Angles are congruent if a transversal cuts two parallel lines. When a transversal cuts two parallel lines, the resulting angles are congruent.

Therefore, ∠2 = ∠6

∠2 + ∠4 = 180° ( Sum of the angles on a straight line is 180°)

∠6 + ∠8 = 180° ( Sum of the angles on a straight line is 180°)

∵  ∠2 = ∠6

∴ ∠6 + ∠8 = 180° ⇒ ∠2 + ∠8 = 180°

∠2 + ∠8 = 180° , Hence Proved.
