Remember: They are supplementary, add the two values and set it equal to 180.
16) The graph is not labeled so I’m not sure where ABC is.
Answer:
Circumference=16pi
Arc Length=8pi
Step-by-step explanation:
Circumference formula=2(pi)(r), or d(pi)
The arc is only half of that in this case, therefore you would only pi(r) or 1/2(d)(pi).
Answer: The distance between A and B is 300 miles.
Step-by-step explanation:
Hi, to solve this problem we have to analyze the information given.
We know that when he was 15 miles away from point B, he was traveling at 60mph. if we apply the formula : time= distance /speed;
- Time: 15 miles / 60 miles per hour = 1/4 hour (15 minutes).
So, he traveled that distance in 15 minutes.
That means that he returned to point A in 3.75 hours (4 hours -15minutes) at a speed of 80 mph.
Applying the formula again to calculate the distance:
- Distance: time x speed: 3.75 hours x 80 mph = 300 miles
The answer is the second one
