Answers

Answer 1
You can see from the bar graph that the unit is meters per second, so the number listed on each material is equal to the distance in meters travelled in one second.

For 21., we see that sound travels 346 meters in 1 second, so we need to multiply that by 20.

346*20=6920

21. 6,920 m

We will use this to answer number 22. We see that stone travels 5,971 m/sec, so we multiply that by 12.

5971*12=71652

22. 71,652 m

For 23 it says estimate, but I will use the actual amounts instead.

Stone: 5,971*17=101,507
Aluminum: 5,000*17=85,000

To find the amount: 101,507-85,000=16507

23. 16,507, or if you want the “estimated” answer, 17000

Kendra buys 5 yards of yellow fabric and 8yards of purple fabric The yellow
costs $2 more per yard than the purple fabric,
She pays a total of 62.80 what
would be the combined cost of 2 yards of yellow and yards of purple
fabric?

Answers

The combined cost of 2 yards of yellow and 1 yard of purple fabric is  $17.69.

What is an expression?

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

Length of yellow fabric = 5 yards

Length of purple fabric = 8 yards

Let x be the cost of per yard purple fabric.

Then, cost of per yard yellow fabric = 2 + x

Now since, Total amount paid is $62.80

Therefore,

5(2 + x) + 8x = 62.8

expanding the brackets we get,

10 + 5x + 8x = 62.8

Solving we get,

10 + 12x  = 62.8

or, 12x = 52.8

⇒ x = 62.8/12

⇒ x = $5.23

Thus the cost of per yard purple fabric = $5.23

Similarly, cost of per yard yellow fabric = 2 + 5.23 = $7.23

Thus, combined cost of 2 yards of yellow and 1 yard of purple

fabric = 2*$5.23 + $7.23

= $10.46 + $7.23

= $17.69

Thus, the combined cost of 2 yards of yellow and 1 yard of purple fabric is  $17.69

A stop sign in the shape of a regular octagon is inscribed in a circle. Find following measure.
m < LRQ

Answers

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.

What is an Intercepted Arc?

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.

With the other method, the one-time fixed costs will total $17,174, and the variable costs will be $20 per book. For how many books produced will the costs from the two methods be the same?

Answers

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.

What is an equation?

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.

Simplify by combining like terms. -(3 z-5)+z

Answers

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.

A meeting room is set up with 16 rows of seats. The number of seats in a row increases by two with each successive row. The first row has 12 seats. What is the total number of seats?
a. How can you find the number of seats in each row using an explicit formula?

Answers

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 system of equations that can be used to determine the cost for each pound of jellybeans and almonds is

2x + 6y = 22

The cost of one pound of jellybeans is $1.25.

The cost of one pound of almonds is $3.25.

What is the cost of one pound of jellybeans and almonds?

Given this two equations:

5x + 3y = 16 equation 1

2x + 6y = 22  equation 2

Take the following steps to determine the required values:

Multiply equation 1 by 2

10x + 6y = 32 equation 3

Subtract equation 2 from equation 3

8x = 10

Divide both sides of the equation by 8: x = 10 / 8

x = 1.25

Substitute for x in equation 1:

5(1.25) + 3y = 16

6.25 + 3y = 16

Line segment AB has a length of 2 units. It is translated 6 units to the right on a coordinate plane to obtain line segment A′B′. What is the length of A′B′? (1 point) a 2 units b 4 units c 6 units d 8 units
Hep please T^T

Answers

The length of A'B' is 2 unit when Line segment AB has a length of 2 units. It is translated 6 units to the right on a coordinate plane.

What is Translation ?

Translation is a rigid transformation in which a figure or a line segment is shifted or moved without changing its shape and size.

That is, if the measurement of segment AB is 2 unit then after translation by any factor its measurement will not change,

So, the measurement of segment A'B' would be 2 unit.

Verification :

Let the coordinates of A and B are (x₁, y₁) and (x₂, y₂) respectively,

Also, the rule of translation 6 unit right is,

(x,y) → (x + 6, y)

By the distance formula,

The measure of segment AB = √(x₂- x₁)² + (y₂ - y₁)²

Thus, if A'B' is the transformed segment of segment AB,

Then, coordinates of A' and B' are (x₁ + 6, y₁) and (x₂ + 6, y₂)

So, the measure of segment A'B' =

√(x₂ + 6 - x₁ - 6)² + (y₂ - y₁)² = √(x₂- x₁)² + (y₂ - y₁)²

Hence, the measure of AB = measure of A'B'.

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) .
