Answer:

[tex]-291[/tex]

Step-by-step explanation:

From the three terms, we can conclude that the arithmetic sequence for this sequence is [tex]a_{n}=4+(n-1)(-5)[/tex].

[tex]a_{60}=4+(60-1)(-5)[/tex]

[tex]=-291[/tex]

∴ The 60th term of the arithmetic sequence is [tex]-291[/tex].

The order is  Mr. Hill, Mrs. Maury, Mrs. Jackson, Mr. Douglas.

Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorise ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.

Given, table shows the portion of votes each candidate get,

Nominees             Voting Portion

Mr. Douglas             9/50

Mrs. Maury                26%

Mr. Hill                       7/20

Mrs. Jackson              0.21

converting the votes in equal ratio,

Mr. Douglas  =   9/50 votes

multiply and divide by 2

Mr. Douglas  =   9 x2/50 x 2 = 18/100

Mrs. Maury =  26% = 26/100

Mr. Hill = 7/20

multiply and divide by 5

Mr. Hill = 7 x 5/20 x 5 = 35/100

Mrs. Jackson  = 0.21 = 21/100

Mr. Hill is winner with most number of votes.

Hence the order beginning with winner is Mr. Hill, Mrs. Maury, Mrs. Jackson, Mr. Douglas.

The rates for both person are equal.

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, two ratios are in proportion when they are equal.

Two ratios or fractions are equal when an equation or a declaration to that effect is utilised.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Given:

Person 1 run 20 laps in 6 minutes.

Then the ratio = 20/6

                        = 10/ 3

Person 2 run 30 laps in 9 minutes.

Then the ratio = 30/9

                        = 10/ 3

So, the rates are equivalent.

Step-by-step explanation:

The next three terms are 15, 26 and 41.

The distance between succeeding terms in an arithmetic series is always the same.

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence.

For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6. An arithmetic progression is another name for an arithmetic sequence.

Given:

First term, a: 2

Common difference, d: 13

So, second term = a+ d

                            = 2 + 13 = 15

and, third term = a+ 2d

                            = 2 + 2(13) = 28

and, fourth term = a+ 3d

                            = 2 + 3(13) = 41

Hence, the next three terms are 15, 26 and 41.

Answer:

I don't know but this might be helpful add and multiply the numbers they give you and divide by 12%

Step-by-step explanation:

The amount of money Kevin earn = $ 232.60

The amount of money Kenneth earn = $ 207.12

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the amount of money Kevin earn = A

Let the amount of money Kenneth earn = B

Salary of Kevin = $ 135

Salary of Kenneth = $ 135

Now , the equation will be

Ratio of Kevin's and Kenneth's commission be = a : b

The value of a : b = 3 : 4

Now , Kevin earns 12 percentage commission

So , the value of a = 12 %

So , the commission earned by Kenneth b = 12 x ( 4 / 3 )

The commission earned by Kenneth b = 16 %

Now , the total amount of products sold by Kevin and Kenneth = $ 610 each

So , the commission of Kevin a = ( 12/100 ) x 610

The commission of Kevin a = $ 73.20

And , the total earning of Kevin = amount of Kevin's salary  + commission of Kevin a

Substituting the values in the equation , we get

The total earning of Kevin A = 135 + 73.2

The total earning of Kevin A = 207.12

Now ,

The commission earned by Kenneth b = ( 16/100 ) x 610

The commission earned by Kenneth b = $ 97.60

The total earning of Kenneth B = amount of Kenneth's salary  + commission of Kenneth b

Substituting the values in the equation , we get

The total earning of Kenneth B = 135 + 97.60

The total earning of Kenneth B = $ 232.60

Therefore , the value of A is $ 207.12 and the value of B is $ 232.60

Hence ,

The amount of money Kevin earn = $ 232.60

The amount of money Kenneth earn = $ 207.12
