Answer: There are 9216 different ways.
Step-by-step explanation:
Since we have given that
Number of couples = 4
Number of people in couples = 8
Number of seats on each floor = 4
Number of ways to select a person from each to send him (or her) to the upper deck would be
Number of ways to select a person to send them to the bottom floor would be
Number of ways to select a person to send them to the upper floor would be :
So, the total number of different ways would be :
Hence, there are 9216 different ways.
Answer:
Rate of slower bus; 90 km/h
Rate of faster bus; 102 km/b
Step-by-step explanation:
We know that formula do distance is;
Distance = speed/time
We are told that One bus travels 12h slower than the other.
Let speed of slower bus be x.
Thus;
Speed of faster bus = x + 12
Speed of slower bus = x
After 3 hours, distance by faster bus = 3(x + 12)
Speed of slower bus = 3x
Since the towns are 576 km apart, then;
3(x + 12) + 3x = 576
Divide through by 3 to get;
x + 12 + x = 192
2x + 12 = 192
2x = 192 - 12
2x = 180
x = 180/2
x = 90 km/h
Faster bus speed = 90 + 12 = 102 km/h

Angle b is 22°
Step-by-step explanation:
- Step 1: Find angle b if a = 68°
Since they are complementary, a + b = 90°
⇒ b = 90 - 68 = 22°
