In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, two ratios are in proportion when they are equal.

According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Given:

we can use the property similar triangle which states the the ratio of corresponding sides of similar triangle are in proportion

Using proportion

x / 20 + x  = 9 / 24

24x = 180x + 9x

24x -9x = 180

15x = 180

x= 12

Again, Using proportion

y/ y+9 = 4/ 10

10y = 4y + 36

6y = 36

y= 6

None of the given polygons appears to be regular.

A regular polygon is a polygon with all sides and angles of equal measure. In other words, a regular polygon is a shape with straight sides that has all angles and sides of equal length.

The simplest example of a regular polygon is a equilateral triangle, which has three sides of equal length and three angles of equal measure. Another example is a square, which has four sides of equal length and four right angles of equal measure.

Figure A is a rhombus, which has opposite sides parallel and all sides equal, but it has two acute angles and two obtuse angles, so it is not regular.

Figure B is a parallelogram, which has opposite sides parallel, but not all sides and angles equal, so it is not regular.

Figure C is a right-angled triangle, which has one right angle, but not all sides and angles equal, so it is not regular.

Answer:

Step-by-step explanation:

Let's call the number of cups sold in April "x".

The total sales in April were $31,250, so we can set up an equation to find x:

2.50 * x = 31,250

Dividing both sides by 2.50, we get:

x = 12,500

So in April, 12,500 cups of coffee were sold.

The total sales in May were 10,150 cups * $2.50 per cup = $25,375.

The average of the sales in April and May was $31,250 + $25,375 / 2 = $28,312.50.

So in June, they sold $28,312.50 / $2.50 per cup = 11,250 cups of coffee.

Answer: There were 12,500 cups sold in April. In May they made $25,375. They sold 11,325 cups and made $28,312.50 in June.

Step-by-step explanation:

       To find the cups of coffee sold in April, we will divide the total sales by price per cup.

    $31,250 / $2.50 = 12,500 cups

       To find the total sales for May, we will multiply the cups sold by the price per cup.

       10,150 * $2.50 = $25,375

       If they sold the average of April and May in June, we will find the average of April and May.

       12,500 cups in April + 10,150 cups in May = 22,650

       22,650 / 2 = 11,325 cups sold in June

       Then, to find the dollar sales, we will multiply by the price per cup again.

11,325 * $2.50 = $28,312.50

Take A, B, C, and D as the quadrilateral's vertices, and BA is created to E. The value of x = 40.

Draw the above diagram and add the angles that are missing.

To determine the value of x, use the information provided in the accompanying diagram.

Take A, B, C, and D as the quadrilateral's vertices, and BA is created to E. (say).

Observe the illustration.

[tex]$& \Rightarrow \angle \mathrm{EAD}=70 \\[/tex]

[tex]$& \Rightarrow \angle \mathrm{EAD}+\angle \mathrm{DAB}=180 \\[/tex]

[tex]$& \Rightarrow \angle \mathrm{DAB}=180-70=110[\because E A B \text { is a straight line and } \mathrm{AD} \text { stands on it. }] \\[/tex]

Apply the total of internal angles in step two.

We are aware that a quadrilateral's inner angle total is 360.

Option (4):  The inverse of the function tells us the number of visits m that can be made for a cost of c.

What is meant by the inverse of a function?

A function takes in values, applies specific operations to them, and produces an output. The inverse function acts, agrees with the outcome, and returns to the initial function.

A function that can reverse into another function is known as an inverse function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. When a function is written as "f" or "F," its inverse is written as " f ⁻¹ " or " F ⁻¹."

Given a function,

  c(m) = 60 + 10m

where c = cost of visiting the gym

            m = number of visits

Then the Inverse function is:

   c(m) - 60 = 10m

m = (c(m) - 60) / 10

Therefore the inverse of the function tells us the number of visits m that can be made for a cost of c.

Answer: C

Step-by-step explanation:

The two variables need to be eliminated. You can do this by multiplication or subtraction.

Multiply by -3 to the top equation will eliminate the x variable in the system

The IQR is the best measure of variability, and it equals 4.

Unit vector notation is a way of representing vectors in which magnitude of vector is equal to 1. A vector is mathematical object that has both magnitude (length) and direction, and can be represented as an arrow.

In unit vector notation, a vector is represented as a combination of a scalar (a numerical value) and a unit vector (a vector with a magnitude of 1 in the same direction).

The most common notation for unit vectors is to use a hat symbol (^) to indicate that a vector is a unit vector. For example, if we have a vector v, then its corresponding unit vector in the same direction would be represented as v. The unit vector in the x-direction is typically denoted as i, and the unit vector in the y-direction is denoted as j.

Unit vector notation is useful in many applications, including physics and engineering, where it is used to describe the direction of forces, velocities, and accelerations. It is also commonly used in computer graphics and game development, where it is used to represent the direction of movement or rotation of objects in a 3D space.
