Answer:
calories
Step-by-step explanation:
Given: The racer moves at 
miles per hour expends energy at a rate of 
calories per hour.
To find: Energy in calories, required to complete a marathon race 
miles at this pace.
Solution: We have,
The racer moves at miles per hour.
The racer expends energy at a rate of calories per hour.
So, energy expended while moving miles 
calories.
Now, energy expended while moving 
mile 
calories.
So, energy expended while moving miles 
calories.
Hence, calories of energy is required to complete a marathon race miles at this pace.
Answer:
Reflection

I think the answer is 31.75
Answer:
20°
Step-by-step explanation:
One way of doing this is to find the constant of proportionality, k:
8k + 6k + 4k = 90° Then 18k = 90°, and k turns out to be 90/18, or 5.
Then the angles are 8(5), 6(5) and 4(5). The smallest of these angles is thus 20°
