It will take 2.2 hours for the trains to meet.
Step-by-step explanation:
Given,
Distance between two trains = 396 miles
Speed of one train = 95 mph
Speed of other train = 85 mph
Combined speed of trains = 95+85 = 180 mph
Distance = Speed * Time
Time = 
Time = 
Time = 2.2 hours
It will take 2.2 hours for the trains to meet.

Answer:
Rational
Step-by-step explanation:
Two broad categories of Real Numbers is:
- Rational Numbers
- Irrational Numbers
Rational numbers are those which can be written in the form of a fraction. When written in form of a decimal, these numbers terminate after few decimals or have a pattern that runs throughout the decimals.
Irrational numbers cannot be written in form of fractions. When written in the form of a decimal numbers, these numbers do not terminate(end) and do not show any pattern.
So, from the above discussion, we can conclude that the answer in the blank will be Rational. Fractions or decimals that stop are known as Rational numbers.
Answer: The first one. 2 to the 20th power over 3 to the 8th power
Step-by-step explanation:
Answer:
( x +2)² + ( y - 4)² = 81
Step-by-step explanation:
The equation for a circle in standard form is ( x – h)² + ( y - k)² = r², where the center is (h, k) and the radius is r.
Putting the question's given information into the formula gives you
[ x – (-2)]² + ( y - 4)² = (9)²
( x + 2)² + ( y - 4)² = 81
They had the same quotient because both of those equations are equal
