Answer:
They will be 140 miles apart 8 hours after the first boy started the trip or 6 hours after the second boy started the trip.
Explanation:
x = the time that the first boy travels at 14 mph
x - 2 = the time the second boy travels at 14 mph
140 the distance between them
Since one travels north and the other east (their roads are perpendicular) the distance between them can be calculated using Pythagorean Theorem
(14*x)^2 + ((x-2)*14)^2 = 140^2
the solutions of the quadratic equation are
x1 = - 6 is not the solution since x > 0
x2 = 8 h is the solution
It's a shield volcano, which is a broad, domed volcano with gently sloping sides, characteristic of the eruption of fluid, basaltic lava. Hope this helps! :)
Answer:
so you know the units in the problem and answer are the same, if they aren't you have to convert them to the same units.
Answer: Option (A) is the correct answer.
Explanation:
When more and more energy is provided to a gas then its atoms move more rapidly.
This rapid and continuous movement converts the gas into hot ionized ions which have positively charged ions and negatively charged electrons.
Therefore, we can conclude that as the atoms move faster, the gas can change into a plasma.
