The wire used for the triangular pendant can have a cost more than 664.65 USD and less than 791.25 USD.

In this problem we find the case of a triangle, in which the length of two sides are known and we need to determine the range of costs associated to the set of all possible triangles. This can be derived by the geometric system described in the image attached below. The minimum and the maximum costs of the pendant:

θ = 0°

l = 10.5 cm - 2.5 cm

l = 8 cm

s = 10.5 cm + 8 cm + 2.5 cm

s = 21 cm

C = (31.65 USD / cm) · (21 cm)

C = 664.65 USD

θ = 180°

l = 10.5 cm + 2.5 cm

l = 13 cm

s = 10.5 cm + 2.5 cm + 12.5 cm

s = 25 cm

C = (31.65 USD / cm) · (25 cm)

C = 791.25 USD

Answer:

15x - y = - 126

Step-by-step explanation:

will make it simple and short

first we need to find the slope (m) first in order to get the equation

given: (-8,6) (-9,-9)

                     y2 - y1         -9  -  6

Slope = m = -----------  =  ------------------ =  15

                      -x2 - x1        -9  -  (-8)

so the equation of the line using point (-8,6) and slope 15 is y - 6 = 15( x + 8)

y - 6 = 15x + 120

using the form equation Ax + By = C,  15x - y = -120-6

therefore... 15x - y = - 126       is the answer

The number of people in the set C ∩ D (customers who purchased both cats and dogs) is obtained by adding the overlap of D and C (3) with the overlap of all 3 circles (1), resulting in a total of 4 individuals.

The correct answer is 4.

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to analyze the overlapping regions in the Venn diagram.

Given information:

- Circle C (cats): 15

- Circle D (dogs): 21

- Circle F (fish): 12

- Overlap of C and F: 2

- Overlap of F and D: 0

- Overlap of D and C: 3

- Overlap of all 3 circles: 1

- Number outside of circles: 14

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to consider the overlapping region between circles C and D.

From the information given, we know that the overlap of D and C is 3. Additionally, we have the overlap of all 3 circles, which is 1. The overlap of all 3 circles includes the region where customers have purchased cats, dogs, and fish.

To calculate the number of people in the set C ∩ D, we add the overlap of D and C (3) to the overlap of all 3 circles (1). This gives us 3 + 1 = 4.

Therefore, from the options given correct one is 4.

Answer:

A) \(x = \dfrac{\log_6(46) + 6}{4}\)

B) \(x = \dfrac{\ln(11)}{2}\)

C) \(x = \dfrac{11}{5}\)

Step-by-step explanation:

A) We can solve for x by taking log base 6 of both sides.

\(\log_6(6^{4x-6}) = \log_6(46)\)

\(4x - 6 = \log_6(46)\)

\(4x = \log_6(46) + 6\)

\(\boxed{x = \dfrac{\log_6(46) + 6}{4}}\)

B) First, we have to divide both sides by 2.

\(2e^{2x} / 2= 22 / 2\)

\(e^{2x} = 11\)

Then, we can solve for x by taking the natural log (log base e) of both sides.

\(\ln(e^{2x})= \ln(11)\)

\(2x= \ln(11)\)

\(\boxed{x = \dfrac{\ln(11)}{2}}\)

C) We can solve for x by raising 2 to the power of each side.

\(2^{\log_2(5x + 5)} = 2^4\)

This cancels the log base 2 on the left.

\(5x + 5 = 16\)

\(5x = 11\)

\(\boxed{x = \dfrac{11}{5}}\)

Step-by-step explanation:

20% off = 20 x 0.8 = 16

plus tax = 16 x 1.13 = 18.08

Answer:

$18.08

Step-by-step explanation:

20% of $20.00 = 0.2 x 20 = $4

Therefore, the sale price of the t-shirt with 20% off = 20 - 4 = $16

If a sales tax of 13% is then applied, final sale price = 16 x 1.13 = $18.08

Two triangles are congruent if they satisfy SSS or ASA or SAS or AAS or RHS criteria.

What is the meaning of congruent triangles?

If two triangles have both the same shape and the same size then it is said that the two triangles are congruent. In other words, two triangles are congruent if they are copies of each other.

We can prove that two triangles are congruent if they satisfy any one of the following criteria:-

SSS (side side side ):- If three sides of one triangle are equal to the corresponding three sides of the other triangle.

SAS ( side angle side ):- If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle.

ASA ( angle side angle ):- If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle.

AAS ( angle angle side ):- If two angles and a none included side of a triangle are equal to the corresponding angles and side of another triangle.

RHS (right hypotenuse side ):- If the hypotenuse and one side of the right triangle are equal to the corresponding side and the hypotenuse of another triangle.

Hence, two triangles are congruent if they satisfy any one of the criteria of congruence (SSS, ASA, SAS, AAS or RHS).

Answer:

  a = -5/11

Step-by-step explanation:

You want to solve the equation -1/4-a-4=7/4a-3.

The first step in solving this 3-step equation can be to add the opposite of (-a) so that the variable 'a' appears only on one side of the equation:

  -1/4 -a -4 +a = 7/4a -3 +a

  -17/4 = 11/4a -3 . . . . . . . . . . . simplify

The second step is to add the opposite of the constant (-3) so that the constant is on one side of the equation, and the variable is on the other side.

  -17/4 +3 = 11/4a -3 +3

  -5/4 = 11/4a . . . . . . . . . . simplify

The third step is to multiply by the inverse of the coefficient of the variable:

  (4/11)(-5/4) = (4/11)(11/4a)

  -5/11 = a . . . . . . . . . . . . . . . simplify

  -1/4 -(-5/11) -4 = (7/4)(-5/11) -3

  -17/4 +5/11 = -35/44 -3

Equating the mathematical expressions, we can determine that the siblings need to sell 12 bags of cookies for them to raise the same amount of money.

Mathematical expressions are the combination of variables, constants, numbers, and values using mathematical operands like addition and subtraction.

Mathematical expressions are also described as algebraic expressions.

The initial amount that you have = $24

Your selling price per bag of cookies, c, = $3

The total amount you will make is given by Expression 1: 24 + 3c

Your sister's selling price per bag of cookies, c, = $5

The total amount your sister will generate is given by Expression 2: 5c

To determine the number of bags of cookies you must sell to raise the same amount of money between the two siblings, we equate the two expressions as follows:

24 + 3c = 5c

24 = 2c

12 = c

Check:

5c = 60 (5 x 12)

24 _ 3c = 60 (24 + 36)

Answer:

m<3 = 66°

Step-by-step explanation:

<3 is an angle with its vertex inside the circle shown in the diagram. This, it's an internal angle.

The measure of an internal angle is equal to half the sum of the measure of the arcs intercepted.

Thus, the equation that shows relationship between <3 and arc WX and arc YZ is shown below:

m<3 = ½(40 + 92)

m<3 = ½(132)

m<3 = 66°

The measure of m<3 = 66°

Since  arc WX = 40' and arc Y Z = 92

So we know that

The measure of an internal angle should be equivalent to half the sum of the measure of the arcs intercepted.

So based on this

m<3 =0.50 (40 + 92)

m<3 = 0.50(132)

m<3 = 66°

hence, The measure of m<3 = 66°

Step-by-step explanation:

tan65 = 27/d , value of tan65 is 2.1445

The based on this example, we can see that the converse of the Pythagorean theorem does not hold for this particular triangle.

To prove the converse of the Pythagorean theorem, we need to show that if the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.

In the given triangle AABC, with vertices at A(1,6), B(1,1), and C(5,1), we can calculate the lengths of the sides using the distance formula or Pythagorean theorem.

AB = sqrt((1-1)^2 + (6-1)^2) = sqrt(25) = 5

BC = sqrt((5-1)^2 + (1-1)^2) = sqrt(16) = 4

AC = sqrt((5-1)^2 + (6-1)^2) = sqrt(40) = 2sqrt(10)

Now, let's check if AB^2 + BC^2 = AC^2:

AB^2 + BC^2 = 5^2 + 4^2 = 25 + 16 = 41

AC^2 = (2sqrt(10))^2 = 4(10) = 40

Since AB^2 + BC^2 is not equal to AC^2, the given triangle AABC does not satisfy the condition for the converse of the Pythagorean theorem.

In accordance with functional theory, definition of functions and kinds of functions, the function is not injective but surjective. (Correct choice: C)

In accordance with functional theory, functions are relations in which each element of the domain is related to only one element of the range. There are three kinds of functions: (i) Injective - Each domain element is related to one distinct element of the range, (ii) Surjective - There are at least two domain elements that are related to an element of the range, (iii) Bijective - The function is both injective and surjective.

Based on all these information, we conclude that the given function has at least two values of the x-axis (domain) related to one value of the y-axis (range). In a nutshell, the function is not injective but surjective. (Correct choice: C)
