Answer:
(r + 20)t = r
Step-by-step explanation:
Distance is constant in the scenario above, distance from home to wedding and wedding back home is the same.
From wedding back home. :
Recall : Distance = speed * time
Distance = r * 1 hour
From home to wedding :
Speed = 20 mph more ; r + 20
Time = t
Distance = (r + 20)* t = (r +20)t
Since the distance are the same, we can equate both :
(r + 20)t = r * 1
= (r + 20)t = r
Answer:
29°: Acute 90°: Right 61°: Acute
Step-by-step explanation:
If an angle is less than 90 degrees, it is acute. If it is greater than 90 degrees, it is obtuse. If it is exactly 90 degrees, it is right.

Let us say the dog eats x pounds of dog food in one month.
There are 12 months in a year.
So applying unitary method:
Quantity of dog food required by dog in 12 months = 12x
Answer : The dog requires 12x pounds of dog food in a year.
