To solve this problem, we need to use combination which is statistical tool to determine the number of ways an event may occur. The combination to select a 5 a side team from 12 students is 792.

<h3>Combination</h3>

This a mathematical technique that is used to determine the number of possible arrangements in a collection of items where the way they're arranged does not matter.

Data;

  • Number of Students = 12
  • Team = 5

The combination for this would be

C = ^1^2C_5 = 792

The combination to select a 5 a side team from 12 students is 792.

What is the area of the figure below please explain!
jeyben [28]

I don't know the area of a parallelogram off the top of my head but you can use the area of the rectangle and the area of the triangle and add those. The area of the triangle is 1/2*base*height and use the pythagorean theorem to find the base. 3² + b² = 5²; 9 + b² = 25; b² = 16; b = 4. The area of the triangle is 1/2*4*3 or 6 in. Since there are two of them, the total area of the triangles are 12 in. The area of the rectangle is length*width or (12 - 4) * 3 which is 8 * 3 or 24in. Add these areas together to get 36in total

The area of a square field is 841m.A rectangular field whose length is twice it's breath has its perimeter equal to square field
lubasha [3.4K]
<h2>Answer with explanation:</h2>

Given: The area of a square field is 841 sq.m

Since side of square = √Area

So, side of square field = \sqrt{841} =29

Thus , side of square field = 29 m

Perimeter of square = 4( side) = 4(29) = 116 m

Let x be the breadth of rectangle then 2x be the length

Perimeter of rectangle = 2 (length+breadth) = 2(2x+x)= 2(3x)=6x

As per question, perimeter of rectangle=  Perimeter of square

\Rightarrow\ 6x=116\\\\\Rightarrow\ x=\dfrac{116}{6}=\dfrac{58}{3}\ m

Length : 2x =2\dfrac{58}{3}=\dfrac{116}{3}\ m

Area of rectangle =  length x breadth

=\dfrac{116}{3}\times\dfrac{58}{3}=\dfrac{6728}{9}\\\\=747\dfrac{5}{9}\ m^2

Area of rectangle = 747\dfrac{5}{9}\ m^2

X+y=2 and x+y=-1 solve by graphing please and show the solution
Sergeu [11.5K]

Answer:

The answer to your question is There is no solution, the lines are parallel.

Step-by-step explanation:

Data

Equation 1     x + y = 2

Equation 2    x + y = -1

Solve for y

Equation 1          y = -x +2

                          y = - x + 2

Equation 2         y = - x - 1

See the graph below

These lines do not cross, so there is no solution. They are parallel.

If the lines have crossed, there  would be a solution.
