Answer:
1120 possible ways
Step-by-step explanation:
In order to find the answer we need to be sure what equation we need to use.
From the given example, let's consider initially only men. Because you have a total of 8 men and we need to chose only 3 men, let's suppose that the 3 chosen men are A, B, and C.
Because A,B,C is the same as choosing C,B,A, which means it doesn't matter the order of the chosen men, we need to use a 'combination equation'.
Because we have two groups (women and men) then we have:
Possible ways = 8C3 * 6C3 (which are the combinations for women and men respectively). Remember that:
nCk=n!/((n-k)!*k!) so:
Possible ways = 8!/((8-3)!*3!) * 6!/((6-3)!*3!) = 56* 20 = 1120.
In conclusion, there are 1120 possible ways.

Step-by-step explanation:
The answer is c
Answer:
Length = 13 cm
Width = 10 cm
Step-by-step explanation:
We are told that;
- The length of the rectangle is 3 cm more than the width
- Thus taking, the width as x cm
- Then, the length will be (x+3) cm
- The perimeter of the rectangle is 46 cm
We are required to determine the dimensions of the rectangle;
We know that the perimeter of a rectangle is given by the formula;
P = 2(l+w)
In this case;
46 = 2 ( x + x + 3)
Thus;
4x + 6 = 46
Solving for x,
4x = 40
x = 10
This means, the width is 10 cm, while the length is 13 cm
Therefore, the dimensions of the rectangle is length 13 cm and width 10 cm
Its also 40°30' because the median is also a bisector in isosceles triangle
