Step-by-step explanation:

Given equation of circle (in general form) is:

8 {x}^{2}  + 8 {y}^{2}  - 16x - 32y + 24 = 0 \\  \\ dividing \: throughout \: by \: 8 \: we \: find :  \\  {x}^{2}  + {y}^{2}  - 2x - 4y + 3 = 0  \\ equating \: it \: with :  \\  {x}^{2}  +  {y}^{2}  + 2gx + 2fy + c = 0 \\ 2g =  - 2 \implies \: g =  -  1\\  2f =  - 4 \implies \: f =  - 2 \\ c = 3 \\   \therefore \:center =  ( - g, \:  \:  - f) = (1, \:  \: 2) \\  \\ radius \: r =  \sqrt{ {g}^{2} +  {f}^{2}  - c }  \\  =  \sqrt{ {1}^{2}  +  {2}^{2}  - 3}  \\  =  \sqrt{1 + 4 - 3}  \\  =  \sqrt{5 - 3}  \\  =  \sqrt{2}  \: units

At Ree Ski Center, the most people will pay for a neck warmer is $10. The manager of Ree Ski Center knows he needs a 30% markup
taurus [48]

Let x be the most the manager can pay the suppliers.

Then, we know from the information given in the question that the manager needs a 30% markup based on cost.

Therefore, the guiding equation will be:

x+\frac{30}{100}x\leq 10

because $10 is the most people will pay for a neck warmer.

Thus, the above equation will become:

x+0.3x\leq 10

1.3x\leq 10

x\leq \frac{10}{1.3}=7.69

\therefore x\leq 7.69

Thus, the most a manager can pay the suppliers for neck warmers and still keep the selling price at $10 is $7.69

What is the common difference or common ratio of the sequence 2, 5, 8, 11, ...?
dem82 [27]
Answer: 
B. 3

Explanation: 
2 + 3 = 5 
5 + 3 = 8 
8 + 3 = 11 

This is how you find the common rate between a sequence of numbers. If you find how to get to on number, you see if it works on another, and so on. If it does, that is the rate.

Complete the proof....
abruzzese [7]

Answer:

The correct options are;

1. Definition of supplementary angles

2. m∠1 + m∠2 = m∠1 + m∠3

3. m∠2 = m∠3

4. Definition of Congruent Angles

Step-by-step explanation:

The two column proof is presented as follows;

Statement           {}                                  Reason

1. ∠1 and ∠2 are supplementary    {}     Given

 {} ∠1 and ∠3 are supplementary

2. m∠1 + m∠2 = 180°        {}                    Definition of supplementary angles

{}   m∠1 + m∠3 = 180°

3. m∠1 + m∠2 = m∠1 + m∠3      {}          Transitive Property

4. m∠2 = m∠3       {}                               Subtraction Property of Equality

5. ∠2 ≅ ∠3       {}                                    Definition of Congruent Angles

Given that angles ∠1 and ∠2 are supplementary angles and angles ∠1 and ∠3 are are also supplementary angles, then the sums of m∠1 + m∠2 and m∠1 + m∠3 are equal, therefore, ∠2 and ∠3 have equal quantitative value and therefore ∠2 = ∠3 and by definition, ∠2 ≅ ∠3.

If the first of three consecutive integers is subtracted from 138, the result is the sum of the second and third. What are the i
Murljashka [212]

Answer:

<h2>45, 46, 47</h2>

Step-by-step explanation:

n, n + 1, n + 2 - three consecutive integers

The equation:

138 - n = (n + 1) + (n + 2)

138 - n = n + 1 + n + 2                 <em>combile like terms</em>

138 - n = 2n + 3           <em>subtract 138 from both sides</em>

-n = 2n - 135               <em>subtract 2n from both sides</em>

-3n = -135            <em>divide both sides by (-3)</em>

n = 45

n + 1 = 46

n + 2 = 47

An expression is defined as a set of numbers, variables, and mathematical operations. The value of the expression (√2)π/(√5) is 2.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The value of the expression (√2)π/(√5) can be written as,

\dfrac{\sqrt2 \pi}{\sqrt5}\\\\= \sqrt{\dfrac25}\pi\\\\=\sqrt{0.4} \times \pi\\\\

= 0.6324 × π

= 1.9869 ≈ 2

Hence, The value of the expression (√2)π/(√5) is 2.
