In how many orders can four girls and four boys walk through a doorway single file if
RideAnS [48]

Answer:

(a) 40,320

(b) 576

Step-by-step explanation:

(a) We are asked to find the number of orders in which four girls and four boys can walk through a doorway single file if  there are no restrictions.

Since there are 8 people in total, so they can walk in 8! ways.

8!=8\cdot7\cdot6\cdot5\cdot4\cdot 3 \cdot 2\cdot1=40,320

Therefore, four girls and four boys walk through a doorway single file in 40,320 ways.

(b) To find the number of ways in which four girls and four boys can walk through a doorway single file if  the girls walk through before the boys.

The total number of ways would be equal to product of 4 girls walking first and 4 boys walking after.

4 girls can walk first in 4! ways and boys can walk after in 4! ways as well.

4!\cdot 4!=4\cdot 3\cdot 2\cdot 1\cdot 4\cdot 3\cdot 2\cdot 1=576

Therefore, four girls and four boys can walk through a doorway single file if  the girls walk through before the boys, in 576 ways.

Need help with math problem if do get 5 star
777dan777 [17]

Answer:

d) 63 square units

Step-by-step explanation:

x = 3 units (base - b)

y = 6 units (width - w)

h = 7 units (length and height - l and h)

  • Area of a rectangle: l*w
  • Area of a triangle: 1/2*b*h

For the triangles:

Area of a triangle: 1/2*b*h

A = 1/2 * 3 * 7

A = 1/2 * 21

A = 10.5

*Since there are two triangles, it would be 10.5 * 2 = 21

For the rectangle:

Area of a rectangle: l*w

A = 7 * 6

A = 42

Now, we add them together:

A = 42 + 21

A = 63 square units

Therefore, the area of the parallelogram is 63 square units

Hope this helps!
