Answer:
16.67%
Step-by-step explanation:
initial rate=30
final rate =25
decreased rate = 30 - 25= 5
Now,
Decreased % = (5 / 30) * 100%
= 16.67%

Step-by-step explanation:
Yes you could because the obtuse angle is greater than 90 degrees so if the acute angle is inside the obtuse you could get an right angle or an 90 degree angle
Answer:
90 mph
Step-by-step explanation:
Against wind DATA:
distance = 600 miles ; time = 5 hrs. ; rate = 600/5 = 120 mph
With wind DATA:
distance = 600 miles ; time = 2 hrs ; rate = 600/2 = 300 mph
Equations:
p + w = 300
p - w = 120
2p = 420
p = 210 mph (speed of the plane in still air)
Since p+w = 300, w = 300-210 = 90 mph (speed of the wind)
