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

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 transactionThe 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.
