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.

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.

Therefore, four girls and four boys can walk through a doorway single file if the girls walk through before the boys, in 576 ways.
It would be 30 because In the triangle the angle 2 is 75 so in the parallelogram it is 150. And that is the same for angle 1. And 150 plus 150 is 300. So u need 60 more. U would divide that by 2 because there are two more angles. So angle 3 is 30. And the one diagonal is also 30.
Answer:
Step-by-step explanation:
Volume is found by length multiplied by width multiplied by height. Therefore our first equation is 2 multiplied by 5 and 1/3 or 16/5 as a mixed number multiplied by 10 3/4 or 43/10 as a mixed number. This will give us the total volume. As there are 8 servings, we will need to divide by 8 or multiply by 1/8 to find the volume of each serving. The final answer is 86/25 which simplified to 3 and 11/25
Step-by-step explanation:
f(x) = x + 1
g(x) = -3x
h(x) = 5-x
find fogoh
first we find fog
f(g(x)) = -3x + 1
then we find fogoh = -3(5-x ) +1
= -15 + 3x +1
= 3x -14
X ≤ 19.2
