Answer:

-24 < -2 < -7/4 < 1/2 < √5

Step-by-step explanation:

The simplification by combining like terms of -(3z -5) + z is -2z + 5.

According to the given question.

We have an expression -(3z -5) + z.

As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same.  when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.

Since, we have to combine the like terms of the given expression -(3z - 5)  +z.

Here -3z and z both are the like terms.

So, we subtract coeffcients of z to simplify the given expression.

Therefore, the simplification of the expression -(3z - 5)  +z is given by

-(3z - 5) + z

= -3z + 5 + z

= -3z + z + 5

= -2z + 5

Hence, the simplification by combining like terms of -(3z - 5) + z is -2z + 5.

The term "intercepted arc" refers to an arc that is "cut off" or "lies between" the specified angle's sides.

The measure of < LRQ is 112.5.

The term "intercepted arc" refers to an arc that is "cut off" or "lies between" the specified angle's sides.

An arc is a segment of a circle's circumference. An intercepted arc is thus one formed when one or two different chords or line segments cut across a circle and meet at a common point known as a vertex.

If an angle is inscribed in a circle, then the measure of the angle equals one half the measure of its intercepted arc.

So, [tex]$m \angle L R Q=\frac{1}{2}(m \overparen{L N Q})$[/tex]

The sum of the measures of the central angles of a circle with no interior points in common is 360 .

Here, 360 is divided into 8 equal arcs and each arc measures

360/ 8 = 45.

Then, m LNQ = m LM + m MN + m NO + m OP + m PQ = 5(45) = 225.

[tex]$m \angle L R Q=\frac{1}{2}(225)=112.5$[/tex].

Therefore, the measure of < LRQ is 112.5.

Step-by-step explanation:

You multiply by 3 each time.

The number of books published by a small publishing company is 3240.

Given that, a small publishing company is planning to publish a new book. The production costs will include one-time fixed costs and variable costs.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of books be x.

With one method, the one-time fixed costs will total $44,714, and the variable costs will be $11.50 per book.

That is, 44,714+11.50x

With the other method, the one-time fixed costs will total $17,174, and the variable costs will be $20 per book.

That is, 17,174+20x

Now, the number of books produced will the costs from the two methods be the same.

So, 44,714+11.50x=17,174+20x

⇒ 44,714-17,174=20x-11.50x

⇒ 8.5x = 27540

⇒ x=3,240

Therefore, the number of books published by a small publishing company is 3240.

The most commonly used explicit of an arithmetic sequence is given as,

an = a + (n - 1) d

Each term in the sequence can easily be solved/computed without knowing the other terms in the sequence. Now by using the given information, we can say that,

2nd row seat = 12+ 1x2

3rd row seat = 12 + 2 x2

nth seat = 12 + (n-1) x 2

16th row seat = 12 + (16–1) x2 = 42

Since the number of seats is increasing at a constant rate, we can calculate the average number of seats in each row by taking the average of the first and last rows

Average number of seats per row = (12 +42)/2= 27

So total seats = average per row x number of rows

= 27 x 16 = 432.

The summation notation for given arithmetic series is ∑21-2n , where n starts from 0.

The given series is 21+19+17+ . . .

On looking at the series we can easily notice that there is an decrease of 2 from one term to the next successive term.

So the formula will be (-2n +/- something).

Our first term is 21 and then decrease of 2, So we can say that the formula will be (21 - 2n) and n starts from 0.

So if n=0, our first term is 21

If n=1, our second term is 19

If n=2, our third term is 17

and so on.

So, we have the expression (21 - 2n).

The solution of the simultaneous equation is given by (-7 , 4) .

A pair of simultaneous equations is the most common representation of a pair of straight lines in the cartesian plane.

For solving a pair of simultaneous equation we can use various procedures such as the matrix method, substitution or the method of elimination.

The given pair of simultaneous equation is given as:

x=−2y+1

3x+8y=11

Let us solve the equations by the method of substitution:

From the first equation we take the value of x and put it in the second equation:

3x + 8y = 11

or, 3 ( -2y + 1 ) + 8y = 11

or, -6y +3 +8y = 11

or, 2y + 3 = 11

or, 2y = 8

or, y = 4

Substituting the value of y as 4 in the first equation we get:

x = − 2y + 1

or, x = - 2 × 4 +1

or, x = -8 +1

or, x = -7

Therefore the solution set of the pair of equations is given by (-7 , 4) .
