The constant of proportionality in the inverse variation is 79.2
Constant of ProportionalityConstant of proportionality is defined as the constant value of the ratio between two proportional quantities. Two varying quantities are said to be in a relation of proportionality when, either their ratio or their product yields a constant. The value of the constant of proportionality depends on the type of proportion between the two given quantities:
Direct Variation Inverse Variation.This is often determined because of the formula used.
Given that the variation here is an inverse variation.
y ∝ 1/ x
y = k / x
k = y₁x₁ = y₂x₂ = y₃x₃
However, in this question, we can simply represent the constant of proportionality as
k = yx
Substituting the values given into the formula above;
k = 24 * 3.3
k = 79.2

Find the area of a regular octagon with a side length of 17 meters and an apothem length of 21
meters. Round your answer to the nearest meter. Be sure to label the unit.
Answer:
Step-by-step explanation:
An octagon is a 2-dimensional shape with 8 sides and the area is the space within the 8 sides of the shape. To calculate the area of the octagon we can use the area of an isosceles triangle. We divide the area of the shape into eight equal isosceles triangles and calculate it accordingly. A regular octagon has the length of the sides equal and the angles between these sides are equal. The measure of each interior angle is 135° and the exterior angles measure 45° each.
Area of Octagon Formula
The formula used to calculate the area of an octagon is:
2s2(1+√2), where s is the length of the side of the octagon.

You are selling hats and mittens at a craft fair. You hope to have $240 in sales. Hats cost $10 and mittens cost $6. a) write an equation in standard form. b) Graph the equation using x- and y- incercepts. (Show your work)
a) The linear equation is given as follows: 10x + 6y = 240.
b) The graph of the linear function is given by the image shown at the end of the answer.
How to define the linear function?The first step is defining the linear function is identifying the variables, which are given as follows:
Variable x: number of hats purchased.Variable y: number of mittens purchased.You hope to have $240 in sales. Hats cost $10 and mittens cost $6, hence the equation is given as follows:
10x + 6y = 240.
The x-intercept is the point (x,0), hence:
10x = 240
x = 24.
The y-intercept is the point (0,y), hence:
6y = 240
y = 40.
Then the line is traced connecting the points (0,40) and (24,0), with only positive values, as they represent countable amounts.

If you take a number, times by 3 then add 5. You get the same as if you took the
number, times by 7 then subtract 8. What is the number?
The number is 4.
If you take a number, times by 3 then add 5, you get (3x + 5).
If you take the same number and times by 7 then subtract 8, you get (7x - 8).
Set the equations equal to each other:
3x + 5 = 7x - 8
Subtract 3x from both sides:
5 = 4x - 8
Add 8 to both sides:
13 = 4x
Divide both sides by 4:
4 = x
Therefore, the number is 4.

What is the perimeter of triangles a, b, and c? DONT EXPLAIN, JUST ANSWER ROUNDED TO THE NEAREST TENTH.
The perimeter of the triangle passing through the points A, B, C is 27.5 cm.
What is a perimeter?A triangle's perimeter and side lengths are measured in the same unit. If the sides' lengths are measured in a different unit, first convert them to that unit. Example 1: Calculate the triangle's perimeter from the information provided. A perimeter is a closed path that encloses, surrounds, or delimits a one-dimensional length or a two-dimensional shape. The circumference of a circle or an ellipse is its outermost boundary.
There are many uses in real life for perimeter calculations. The length of fence needed to enclose a yard or garden is known as the calculated perimeter.
From the figure,
The triangle is passing through the points A(4, 0), B(-6, 5), C(3, 3)
By using distance formula, we have to calculate the lengths of AB, BC, CA
Length of AB=√(-6-4)²+(5-10)²
=√125
Length of BC=√(3+6)²+(3-5)
=√85
Length of CA=√(3-4)²+(3-10)²
=√50
The perimeter of a triangle=AB+BC+CA
=√125+√85+√50

Suppose S is the set of integers that are multiples of 3, and T is the set of integers that are odd. Prove that |S| = |T| by constructing a bijection between S and T.
The bijection could be defined from the set of numbers and it is proved.
We can define a bijection f from S to T as follows: for any integer x in S, let f(x) = x + 1.
To show that f is a bijection, we need to prove that it is both injective and surjective.
To prove that f is injective, suppose f(x) = f(y) for some x, y in S. Then x + 1 = y + 1, which means x = y. Thus, f is injective.
To prove that f is surjective, let y be an arbitrary element of T. Since y is odd, we can write y = 2n + 1 for some integer n. Now consider the element x = 3n in S. We have f(x) = x + 1 = 3n + 1 = y, so f is surjective.
Therefore, f is a bijection from S to T, so |S| = |T|.

Tickets to a basketball game can be ordered online for a set price per ticket plus a $5.50 service fee. The total cost in dollars for ordering 5 tickets is $108.00. Which linear function represents c, the total cost, when x tickets are ordered? (A service fee is a single fee applied to the total, no matter the number of tickets purchased).
c(x) = 5.50 + 20.50x
c(x) = 5.50x + 20.50
c(x) = 5.50 + 21.60x
c(x) = 5.50x + 21.60
Answer:
c(x) = 5.50 + 21.60x
Step-by-step explanation:
To start, we are told that the service fee of 5.50 is added to the set price per ticket. So we can automatically eliminate B and D
Now, to find how much it costs per ticket, we have to divide 108.00 by 5 since we are told that it costs $108 to buy 5 tickets
108.00/5 = 21.60
This means that it costs $21.60 per baseball ticket
