The rate of change is given a 5 / 6. The values we have here are not linear

The rate of change (r.o.c) is the change in y (or the dependent variable) for every unit change in x (or the independent variable). In this case, the r.o.c is

(10-5) / (12-6) = 5/6.

This is not linear because linear is a relationship between a variable and a constant, here the relationship between y and x is not linear because the change in y is not constant with respect to the change in x.

The perimeter of triangle NPQ is calculated to be 72 when NPQ is given congruent to RSQ.

Perimeter of triangle NPQ = 7x + 2

Triangle perimeter: RSQ = 10x - 4

As triangle NPQ is given congruent to triangle RSQ, we have,

NQ / RQ = PQ / SQ = 24 / 32 = 21 / 28 = 3 / 4

The above ratio can be equated to the ratio of perimeters of the triangles NPQ and RSQ.

Perimeter of triangle NPQ/Perimeter of triangle RSQ = 7x + 2/10x - 4 = 3/4

7x + 2/10x - 4 = 3/4

To solve this system of equations, we can use the method of elimination. The goal is to eliminate one of the variables, such as x or y, by adding or subtracting the equations.

First we can eliminate the y variable by adding the two equations together:

X + 3y = 14

2x - 3y = -8

3x = 6

Dividing both sides by 3:

x = 2

Now we have the value of x, we can substitute it back into one of the original equations:

X+3y=14

2 + 3y = 14

Subtracting 2 from both sides:

3y = 12

Dividing both sides by 3:

y = 4

So the solution of the system of equations is (x,y) = (2,4)

To check the solution, we can substitute the values back into the original equations:

x + 3y = 14

2 + 3(4) = 14

2 + 12 = 14

14 = 14

and

2x - 3y = -8

2(2) - 3(4) = -8

4 - 12 = -8

-8 = -8

As the equation holds true, the solution (2,4) is correct.

The four inequalities are a + c ≤ 400, 10a + 5c ≥ 3000, a ≥ 0 and c ≥ 0. The club must sell 200 children tickets and 200 adult tickets.

What is an inequality?

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.

The value for one ticket is - $10

The value for one children's ticket is - $5

The total amount that need s to be earned is - $3000

The number of seats in the auditorium is - 400

Let the number of children be = c and the number of adults be = a.

Then the inequality will be -

a + c ≤ 400

10a + 5c ≥ 3000

a ≥ 0

c ≥ 0

The inequalities will have a straight line as (≤,≥) symbols are used in the inequalities.

Write the two inequalities in equation form -

a + c = 400....(1)

10a + 5c = 3000 or 2a + c = 600....(2)

Subtract equation (1) from (2) -

2a + c - (a + c) = 600 - 400

2a + c - a - c = 200

a = 200

a = 200

Substitute the value of a in equation (1) -

200 + c = 400

c = 400 - 200

c = 200

So, the intersection point is (200,200) and the number of children is 200 whereas the number of adults is 200.

Therefore, the graph is obtained.

The required selling price of the game after two discount is $63.75.

The term discount designates a sum or a percentage subtracted from an item's usual selling price. Make sure you need all of the items you plan to get before waiting until after the holiday to make a purchase. A discount is a decrease in the cost of a commodity or service. ​

Discount = 25%,

Additional discount = 15%

Then,

Net discount is = 36.25%

We have,

Price of game = $100

Discount amount = 36.25% of $100 = $36.25

So, the selling price of the game after discount = $100 - $36.25

= $63.75

Thus, required selling price of the game is $63.75.

The equation of the total cost for the cover charge and drinks in point-slope form is y = 6x + 5.

The point-slope form of a linear equation is given by -

 [tex]y - y_1 = m(x- x_1)[/tex]

where m is the slope and [tex](x_1, y_1)[/tex] is a point on the line.

Here, the total cost for the cover charge and drinks can be represented by the equation y = mx + b, where y is the total cost, x is the number of drinks, m is the cost per drink, and b is the cost of the cover charge.

We know that the cover charge is $5 and drinks are $6 each, so, we can find the slope (m) of the equation by using the cost per drink which is m = 6.

We can also find the point [tex](x_1, y_1)[/tex] by using the cover charge cost which is (0,5).

Therefore, the equation in point-slope form of the total cost for the cover charge and drinks will be -

y - 5 = 6(x-0)

y - 5 = 6x

y = 6x + 5

The bag can hold a maximum of 53 pounds before breaking, and Ani has already placed 29 pounds in the bag. To find out how many more pounds she can place in the bag, we can subtract the weight already in the bag from the maximum weight the bag can hold:

53 - 29 = 24

So Ani can place 24 more pounds in the bag before it breaks.

The inequality to represent this situation is:

weight in bag + x <= 53 (x represents the amount of weight Ani can put in the bag before it breaks)

To find the solution, we can substitute the value of weight in bag and get

29 + x <= 53

Now we can solve the inequality for x

x <= 24

The solution is x <= 24, which means Ani can place 24 more pounds or less in the bag before it breaks.

To graph the solution, we can start with the number line, and plot the point 24 to the right of the origin, and shade the region to the left of the point. This represents the solution set of x <= 24, which means Ani can place 24 more pounds or less in the bag before it breaks.

In the right-angle triangle RQS the measure of m∠R = 90°, m∠Q = 59° and m∠S = 31°.

What is a right-angled triangle?

Any two sides of a triangle's three sides must always add up to more than the third side since a triangle is a regular polygon with three sides. This distinguishing characteristic of a triangle. A right-angle triangle is one that has angles between its two sides that equal 90 degrees.

A right-angled triangle RQS is given.

The measure of ∠R is given as = 90°.

The measure of ∠Q is given as = (2x + 33)°.

The measure of ∠S is given as = (5x - 34)°.

According to the properties of the triangle, the sum of all angles of a triangle equals 180°.

So, the equation will be -

∠R + ∠Q + ∠S = 180°

Substituting the values into the equation -

90° + (2x + 33)° + (5x - 34)° = 180°

Combining the like terms -

90° + 2x + 33° + 5x - 34° = 180°

7x + 89° = 180°

7x = 180° - 89°

7x = 91°

x = 13°

The measure of ∠Q - (2x + 33)°

∠Q = 2(13°) + 33°

∠Q = 26° + 33°

∠Q = 59°

The measure of ∠S - (5x - 34)°

∠S = 5(13°) - 34°

∠S = 65° - 34°

∠S = 31°

Therefore, the measures of angles are 90°, 59° and 31°.

P(boy | picked up boy) = P(picked up boy | boy) * P(boy) / P(picked up boy)
