Ryan earns $5 for each small dog he walks and $8 for each large dog he walks. Today he walked 8 dogs and made a total of $49. How many small dogs did Ryan walk?
Ryan walked
small dogs.

Answers

Answer 1

Answer:

small dogs= 5

large dogs= 3

Step-by-step explanation:

Step one:

given data

let the  number of small dogs be x

and the number of large dogs be y

Ryan earns $5 for each small dog he walks and $8 for each large dog he walks.

He walked 8 dogs and made a total of $49

so

5x+8y=49----------1

x+y=8---------------2

x=8-y

5(8-y)+8y=49

40-5y+8y=49

collect like terms

3y= 49-40

3y=9

divide both sides by 3

y=9/3

y=3

put y= 3 in eqn 2

x+3=8

x=8-3

x=5

Make a Matlab script to make row 2 of matrix A equal to first row of A multiplied by the negative of the first element of row 2 plus the original row 2.

A= [2 -1 10]
[-3 8 4]

Answers

Answer:

[tex]X=\begin{Bmatrix}2& 1 &10 \\-3 & 5 & 4\end{Bmatrix}[/tex]

Step-by-step explanation:

From the question we are told that

Matrix is given as [tex]A=\begin{Bmatrix}2 & -1 & 10\\-3 & 8 & 4\end{Bmatrix}[/tex]

Generally let the change in matrix be given as X

[tex]X_1_2 = 2*(-(-1)) + - 1 = 1X_2_2 = -3 * (-(-1))+ 8 = 5[/tex]

Matlab output

[tex]A=[2 -1 10;-3 8 4]\\a=(A(1,1)*-A(1,2))+A(1,2)\\b=(A(2,1)*-A(1,2))+A(2,2)\\X=[A(1,1) a A(1,3); A(2,1) b A(2,3)]\\[/tex]

Generally the matrix that makes row 2 of matrix A equal to first row of A multiplied by the negative of the first element of row 2 plus the original row is

[tex]X=\begin{Bmatrix}2& 1 &10 \\-3 & 5 & 4\end{Bmatrix}[/tex]

Answer: In 4

Step-by-step explanation: 8*4=32

or

32;8=4

The simplified form for the expression ln 32 - ln 8 is ㏑ 4.

What is Natural Logarithms?

Logarithms are generally inverse functions of the exponential functions. There are 2 main logarithms that we deal with. Logarithms with base 10 and logarithms with base [tex]e[/tex].

Logarithms with base [tex]e[/tex] is called Natural logarithms.

[tex]log_e[/tex] = ㏑

Given expression is ㏑ 32 - ㏑ 8.

We have to know the rule for logarithms to solve this.

We have the division rule of logarithms which states that,

㏑ (a / b) = ㏑ a - ㏑ b

Here, a = 32 and b = 8.

㏑ 32 - ㏑ 8 can be written as,

㏑ 32 - ㏑ 8 = ㏑ (32 / 8)

                    = ㏑ 4

Hence the simplified form is ㏑ 4.

Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form. 125, 25, 5, .. ..​

Answers

Answer:

Given sequence is an arithmetic sequence.

Step-by-step explanation:

Given sequence is:

125, 25, 5, .. ..​

Here

[tex]a_1 = 125\\a_2 = 25\\a_3 = 5[/tex]

A sequence is geometric sequence when the common ratio of consecutive terms is same. It is denoted by r.A sequence is an arithmetic sequence when the common difference of consecutive terms is same. It is denoted by d.

Finding the common ratio

[tex]r = \frac{a_2}{a_1} = \frac{125}{25} = 5\\r = \frac{a_3}{a_2} = \frac{25}{5} = 5[/tex]

As we can see that the common ratio is same, the given sequence is a geometric sequence.

Answer:

this is a geometric sequence and the common ratio is equal to 1/5.

Rectangle ABCD is graft in the coordinate plane. The following are the verticals of the rectangle A(2,0) B(6,0) C(6,7) D(2,7)

What is the rectangle of ABCD?

Answers

Answer:

28 unit^2

Step-by-step explanation:

The computation of the area of the rectangle is shown below:

As we know that

The Area of the rectangle is
