A fraction is represented by the division of a term x by a term y, such as in the equation presented as follows:

Fraction = x/y.

The terms that represent x and y are listed as follows:

In this problem, we are given two fractions, and their decimal equivalents are given as follows:

Hence the numeric value of the expression is given as follows:

4×1+1×1/100+9×1/1000 = 4 + 0.01 + 0.0019 = 4.0119.

Which is the decimal number represented by the fraction.

Using the proportion rule, the ratios 1/3 and 2/5 does not form a proportion.

In the given equation,

We have to check the ratios 1/3 and 2/5 form a proportion or not.

As we know that proportion is a ratio in which both ratios are equal to each other.

So to check whether the given statement is proportion or not we put both equation equal to each other.

So the ratios are 1/3 and 2/5.

Now checking the proportion.

1/3=2/5

Multiply by 15 on both side.

1/3 ×15=2/5 ×15

Simplifying

1×5=2×3

5=6

As we can see that both side is not equal so the given ratio is not proportion.

Co-interior angles are the two angles that occur between two parallel lines intersected by a transversal.

The sum of the co-interior angles is 180 degrees.

The value of x is 15.

The angles that are in the same position on two parallel lines intersected by a transversal line on the parallel lines.

Corresponding angles are equal.

We have,

Co-interior angles are the two angles that occur between two parallel lines intersected by a transversal.

The sum of the co-interior angles is 180 degrees.

(8x + 9)° and 51° are co-interior angles.

So,

8x + 9 + 51 = 180

8x = 180 - 60

8x = 120

x = 120/8

x = 15

Thus,

The equation of the parabola from the vertex is f(x) = -3(x - 5)² + 9

The equation of the function is given as

f(x) = 3x²

Also, we have

Vertex = (5, 9)

The form of the equation is given as

f(x) = a(x - h)² + k

Where

Vertex = (h, k)

This means that

Vertex = (h, k) = (5, 9)

Substitute (h, k) = (5, 9) in the equation f(x) = a(x - h)² + k

So, we have

f(x) = a(x - 5)² + 9

This also means that

f(x) = -3(x - 5)² + 9

The -3 is gotten from f(x) = -3x²

Hence, the equation of the parabola is f(x) = -3(x - 5)² + 9

The probability of choosing a box and picking two quarter coins in a row is 1/108

Probability is the branch concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1. 0 indicates impossibility of the event and 1 indicates certainty.

Probability= sample space / total possible outcome

therefore probability of choosing two quarters in a row = 1/6×1/6= 1/36

The probability of choosing the first box =1/3

Therefore the probability of choosing the first box and picking two quarters In a row is 1/36×1/3= 1/108.

Since box two contain no quarter and box three has only one quarter , the probability of choosing two quarters in a row is 0.

Therefore the probability of choosing a box at random and picking two quarters in a row is 1/108.

Answer:

slope = 16/13, increasing

Step-by-step explanation:

solve for the slope

-1.2-(-2.8)/(6.4-5.1)

= 16/13

it's positive meaning it's increasing

The required expression 16m + 6n - 8 represents the perimeter of the triangle. which is the correct answer would be option (D).

A triangle has side lengths of (7m - 2) centimeters, (9m - 5) centimeters, and (6n - 1) centimeters.

The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.

The perimeter of the triangle = (7m - 2) + (9m - 5) + (6n - 1)

Rearrange the terms likewise in the above equation,

The perimeter of the triangle = 7m + 9m + 6n - 2 - 5 - 1

Apply the arithmetic operation to get the required expression

The perimeter of the triangle = 16m + 6n - 8

Therefore, the required expression 16m + 6n - 8 represents the perimeter of the triangle.

Answer:

BC = 7.9 cm

Step-by-step explanation:

To construct triangle ABC:

The answer is : p = -4

the following are the steps to solve it::

13 - 3p = -5 (3 + 2p)

calculate the area of the right hand first by multiplying the number 5 by the number in brackets

13 - 3p = -15 - 10p

move everything that contains p to the left side

13 - 3p + 10p = - 15

count all containing p

13 + 7p = -15

move the ones that don't contain p to the right

7p = -15 - 13

Graph will shift from(0,0) to (3,4) after the shifting happens due to change in expressions of the parent function.

Graph transformation is the process by which an parent graph, or graphed equation, is changed to produce a variation of the proceeding graph. It's a common type of problem in algebra, specifically the modification in algebraic equations.

The deduced parent function is [tex]\sqrt{x}[/tex]

So, Domain= (0 , ∞)

     Range= (0 , ∞)

Let us take (0,0) as the point and see the shifting of the point with respect to (0,0).

Step-by-step explanation:

To solve any equation/inequality:

1. get the variable to show up exactly once

2. isolate it

[tex]\frac{-10+r}{2} \ge -13[/tex]

Multiply both sides by 2 and simplify (note that we're multiplying by a positive, not a negative, so the direction of the inequality stays the same, whereas multiplying or dividing by a negative would have changed the direction of the inequality)

[tex]\frac{-10+r}{2} *2 \ge -13 *2[/tex]

The actual price of an item is $1371.49.

Given that, the discount percentage is 12.5% and the selling price is $1200.

A discount is the reduction of either the monetary amount or a percentage of the normal selling price of a product or service.

Let the actual price be x.

Now, x-12.5% of x =1200

⇒ x- 12.5/100 ×x=1200

⇒ x- 0.125x=1200

⇒ 0.875x=1200

⇒ x=1200/0.875

⇒ x=$1371.49
