how did the environment shape seljuk empire?

Answers

Answer:

By the second quarter of the 13th century, the Seljuks had become an export nation, although they still imported more that they exported. They also developed many local industries and traded their own goods among the cities of the Empire. These industries included the production of alum and refined sugar.

Answer:

The Great Seljuk Empire emerged in the midst of division and chaos in the Islamic world. From migratory people, they transformed into conquerors that gave unity in the Middle East for a time. Some settled in a land they called their home even to this very day – Turkey

The table shows the types of information collected by a store regarding customer purchases. Which of the following data could be used in a geographical information system (GIS) to increase sales?

Answers

A geographical information system (GIS) is an information system that is used to manage data. They are also used to create and organize data. The total transaction amount can be used by the GIS to increase sales

From the attached table, we have the following data:

Zip code areaNumber of customersNumber of transactionsTotal transaction amountAmount per transaction

The usage of each data is as follows:

The zip code can be used to determine the region of the customers.

The number of customers and the number of transactions can be used to determine the rate of transactions per customer

We observe that, the total transaction amount is the product of the number of transactions and the amount per transaction.

This means that the total transaction amount is a summary of two other columns which deals directly with sales.

Information about total transaction amount can then be used independently to determine, predict and increase the sales of the store.

The length of a new rectangular playing field is 7 yards longer than triple the width. If the perimeter of the rectangular playing field is 438 ​yards, what are its​ dimensions?

Answers

Explanation:

L = 7+ 3W

the perimeter = 438

2(L+W) = 438

by using substitution :

2(7+3W+W) = 438

2(4W+7) = 438

4W+7 = 438/2

4W+7 = 219

4W = 219-7

4W = 212

W = 212/4 = 53

L = 7 + 3(53)

L = 7 + 159 = 166

so, the dimensions : the length = 166 yards

and the width = 53 yards

L = 7+ 3W

the perimeter = 438

2(L+W) = 438

by using substitution :

2(7+3W+W) = 438

2(4W+7) = 438

4W+7 = 438/2

4W+7 = 219

4W = 219-7

4W = 212

W = 212/4 = 53

L = 7 + 3(53)

L = 7 + 159 = 166

so, the dimensions : the length = 166 yards

and the width = 53 yards

What is the area of rectangular field?

Width = w

triple the width = 3*w = 3w

Length = 7 yards longer than triple the width = 3w + 7

Perimeter = 438 yards

2*(length +width) = 438

2*(3w+ 7 + w) = 438       {Combine like terms}

2 * (4w + 7)     = 438

2*4w +2*7 = 438       {Use distributive property}

8w + 14 = 438          {Subtract 14 from both side}

8w = 438 - 14

8w = 424          {Divide both sides by 8}

w = 424/8

w = 53 yards

Length = 3*53 +7 = 159 + 7 = 166 yards

Width = 53 yards

Length = 166 yards

The length and width of another rectangular field with same perimeter but a larger area is 80 m by 70 m.The perimeter of the existing field is

2(l + b)

= 2(90 + 60) = 2(150) = 300 yards

So we want another field having the same perimeter but a larger area.

Therefore, L = 7+ 3W

the perimeter = 438

2(L+W) = 438

by using substitution :

2(7+3W+W) = 438

2(4W+7) = 438

4W+7 = 438/2

4W+7 = 219

4W = 219-7

4W = 212
