Just say if a lb cost $2.17 divide 2.17 by 4 which is 0.5425 and 0.5425 times 3 = 1.6275 and 2.17 + 1.63 which is rounded = 3.7975
So you want to find how many miles are being flown in one hour.
There are 60 minutes in one hour so you want to find how many times 15 goes into 60 so you can then multiply that by 115.
60 / 15 = 4.
Now multiply 115 by 4,
115 x 4 = 460
Therefore the plane is flying at B. 460 mph.
Hope I helped!
Answer:
The passenger train is moving at 45 miles per hour
Step-by-step explanation:
Let the amount of time it took the two trains to travel the distance = t.
Since the two trains traveled the distance at the same time,
Rate of the passenger train =
Rate of the freight train =
<em>Where t is in hours.</em>
From the problem, we can see that the rate of the freight train was 15 miles per hour slower than the rate of the passenger train. Mathematically, we can represent this as
from the above equation, we can now get our value for t as
We have our time of travel for the two trains as 4 hours.
The rate of the passenger train can now be calculated by 180/4 = 45 miles per hour
Answer:
70 degrees
Step-by-step explanation:
rectange angle total = 360
1 corner = 90
90-20 = 70
The answer is [ all real numbers ]
The domain are the input values which makes the function defined and real.
Since we don't have any constraints or any undefined points, the domain could be literally anything. Thus proves out answer.
Best of Luck!
