Answer:

x=1/8

Step-by-step explanation:

First we need to isolate the variable. We can do that by subtracting 3 from each side. You then get: 24x-2=1. Then, to completely isolate it, add 2 to each side. We get 24x=3. Now divide 24 from each side to get only x. We get 3/24, which can be rewritten as 1/8.

Fit-quest charges a one-time registration fee of $50 plus $5 per fitness class. Fitnasium charges no registration fee, but charges $8 per fitness class. For how many fitness classes does Fitnasium cost less than or the same as Fit-quest?

What are Arithmetic operations?

Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

We have been given that Fit-quest charges a one-time registration fee of $50 plus $5 per fitness class. Fitnasium charges no registration fee, but charges $8 per fitness class.

Let the number of classes would be x

⇒ 50 + (5x) = 8x

Rearrange the terms of x in the above equation,

⇒ 8x - 5x = 50

⇒ 3x = 50

⇒ x = 50/3

Apply the division operation,

⇒ x = 16

Therefore, 16 of the fitness classes do Fitnasium cost less than or the same as Fit-quest.

Which relationship is an inverse variation?

x 1 2 3 4
f(x) 4 16 36 64



x 2 4 6 8
f(x) 6 12 18 24

Answers

The relation that is an inverse variation is the one in the first table:

x 2 4 6 8

f(x) 12 6 4 3

Which relation is an inverse variation?

An inverse variation between two variables x and y can be written as follows:

y = k/x

Where k is a constant.

Notice that x is on the denominator, so, as x increases, the value of y decreases.

Now, for example if we use the values of the first table:

x 2 4 6 8

f(x) 12 6 4 3

The first pair is (2, 12)

Replacing that in the inverse variation formula we get:

12 = k/2

12*2 = k

24 = k

For the second pair (4, 6) we will get:

6 = k/4

6*4 = k

24 = k

And so on for all the pairs. If the variation is inverse, you should always get the same value of k (like in this case).

So this is the correct answer.

Step-by-step explanation:

Well, the equation format your question is asking for is Point-slope form which is represented by:

[tex]y - y^{1} = m (x - x^{1})[/tex]

[tex]y^{1}[/tex] = y in point

[tex]x^{1}[/tex] = x in point

m = slope

A regular hexagon is inscribed in a circle with radius 9 cm. Find the area

Answers

Answer:

121.5sqrt(3)

Step-by-step explanation:

Ok, so all regular hexagons are made out of 6 equilateral triangles. If the hexagon is inscribed in the circle, the radius lines up with a side of one of the 6 equilateral triangles and you get 6 equilateral triangles with a side length of 9.

The formula for an equilateral triangle's area is (a/2)^2 * sqrt(3) where a = side length. That means we just plug in 9 to find the area of one of these six triangles. We get 20.25sqrt(3).

We multiply this by 6 (to find the sum of the areas of 6 equilateral triangles) and get 121.5sqrt(3)

The area of the hexagon will be 210.4 cm².

What is a hexagon?

The definition of a hexagon in mathematics and geometry is a polygon with six straight sides that is closed in two dimensions.

Given, a circle with a radius of 9 cm. which have a regular hexagon whose all corner touch the circle. If we draw a radius of a circle at the corner of the hexagon. then we get six equilateral triangles.

A regular hexagon is 6 equilateral triangles of side r and area

Area of triangle  = (r/2)(√3r/2)

so the total area is

A(hex ) =  (6/4) √3r²  =  3√3(r²)/2

r = 9m so

A = 210.4m²

Hence the Area of the given hexagon is 210.4 square meters.

One person suggests that Paul can make the diameter of the hole 1 inch greater than that of the ball. Another suggests the diameter should be 2inches greater. Which suggestion should Paul choose? Explain Use the excerpt from Benjamin Franklins letter to James Parker to answer the question.Excerpt from a letter by Benjamin Franklin to James Parker, March 20, 1751I have, as you desire, read the Manuscript you sent me; and am of Opinion, with the publick-spirited Author, that securing the Friendship of the Indians is of the greatest Consequence to these Colonies; and that the surest Means of doing it, are, to regulate the Indian Trade, so as to convince them, by Experience, that they may have the best and cheapest Goods, and the fairest Dealing from the English; and to unite the several Governments, so as to form a Strength that the Indians may depend on for Protection, in Case of a Rupture with the French; or apprehend great Danger from, if they should break with us. . . .A voluntary Union entered into by the Colonies themselves, I think, would be preferable to one imposd by Parliament; for it would be perhaps not much more difficult to procure, and more easy to alter and improve, as Circumstances should require, and Experience direct. It would be a very strange Thing, if six Nations of ignorant Savages should be capable of forming a Scheme for such an Union, and be able to execute it in such a Manner, as that it has subsisted Ages, and appears indissoluble; and yet that a like Union should be impracticable for ten or a Dozen English Colonies, to whom it is more necessary, and must be more advantageous; and who cannot be supposed to want an equal Understanding of their Interests.Were there a general Council formd by all the Colonies, and a general Governor appointed by the Crown to preside in that Council, or in some Manner to concur with and confirm their Acts, and take Care of the Execution; every Thing relating to Indian Affairs and the Defence of the Colonies, might be properly put under their Management. Each Colony should be represented by as many Members as it pays Sums of Hundred Pounds into the common Treasury for the common Expence; which Treasury would perhaps be best and most equitably supplyd, by an equal Excise on strong Liquors in all the Colonies, the Produce never to be applyd to the private Use of any Colony, but to the general Service. Perhaps if the Council were to meet successively at the Capitals of the several Colonies, they might thereby become better acquainted with the Circumstances, Interests, Strength or Weakness, &c. of all, and thence be able to judge better of Measures proposd from time to time: At least it might be more satisfactory to the Colonies, if this were proposd as a Part of the Scheme; for a Preference might create Jealousy and Dislike.Analyze the excerpt from Benjamin Franklins letter to explain how competition among European powers led to the French and Indian War and encouraged unity among the colonies.
