Answer: a system of equations that could be used to find the cost of the wrapping papers are

2x + y = 41

7x + y = 106

Step-by-step explanation:

Let x represent the cost of one roll of plain wrapping paper.

Let y represent the cost of one roll of holiday wrapping paper.

Brenda sold 2 rolls of plain wrapping paper and 1 roll of holiday wrapping paper for a total of $41. This can be expressed as

2x + y = 41

Jessica sold 7 rolls of plain wrapping paper and 1 roll of holiday wrapping paper for a total of $106. This can be expressed as

7x + y = 106

Uma pessoa comprou um terreno quadrado 81 m2 e deseja aumentar 19 m2 na area dele de que maneira ele continue em forma de quadra
Likurg_2 [28]

Answer:

the new perimeter of the land is 40m

Step-by-step explanation:

The computation of the new perimeter of the land is given below:

Since the square plot is 81m^2

It could be increased by 19m^2

So the total would be

= 81m^2 + 19m^2

= 100m^2

Each side is 10m

Now the perimeter is sum of all sides

= 10m + 10m + 10m + 10m

= 40m

hence, the new perimeter of the land is 40m

The mean of the following frequency distribution is 25.2. Find the missing frequency x.
sattari [20]

Answer:

Solution:-

Frequency Distribution     Frequency     Mid values     F*M

0 - 10                                    8                     5                40

10 - 20                                  x                    15               15x

20 - 30                                 10                   25               250

30 - 40                                 11                   35               385

40 - 50                                  9                    45               405

_____________________________________________________

                                         Σf = 38+x                      Σfm = 1080+15x

______________________________________________________

Given Mean = 25.2

Mean = Σfm/Σf

25.2 = 1080+15x/38+x

25.2 × (38+x) = 1080+15x

957.6+25.2x = 1080+15x

25.2x - 15x = 1080 - 957.6

10.2x = 122.4

x = 122.4/10.2

x = 12

Missing frequency = 12  Answer

Gnesinka [82]

Answer:

Step-by-step explanation:

The highest power of x here is 3, so this is a third degree polynomial.  Since the coefficient of the highest power term is +, we know that the graph approximates that of the parent function y = x^3, and that this graph begins in Quadrant III, enters Quadrant I and continues to move upward in Quadrant I.
