Answer:
60 seconds, 7715 feet
Step-by-step explanation:
Plane A and B start out 615 feet apart, and we find this by subtracting the height of plane A from plane B, getting 5000-4385=615. Now we have to find how many more feet of altitude plane A is gaining per second over plane B.
To find this we subtract 45.25 from 55.5 and get 10.25 feet per second. Now to find out how many seconds until they'll be at the same altitude we simply divide 615 by 10.25, getting 60 seconds.
For the second part, to find the altitude at this point, we simply multiply the altitude gain of one of the planes per second by the time of 60 seconds to get how much altitude they gained over that time, and add it to the starting altitude. Doing this with plane B we get 45.25*60=2715, and we add that to 5000 to get the final answer of 7715.
The answer is 2-7=5 is the answer
In my opinion the ages for drinking/smoking should not be raised to 21. While I am not a fan of either and they almost never lead to good things, it just seems odd to me that a person can fight for his country at 18, but can't smoke or drink.
Answer:
Angles 5 and angle 2 are supplementary angles
Step-by-step explanation:
Angle 2 and angle 6 are corresponding angles and corresponding angles are equal when we have parallel lines
Angles 5 and angle 6 are supplementary angles since they form a line
Replace angle 6 with angle 2 since they are equal
Angles 5 and angle 2 are supplementary angles
