- Natural numbers will Always be whole numbers.
Natural numbers are positive integers (whole numbers), so, they are always whole numbers.
- Integers will Sometimes be natural numbers.
Not all integers are natural numbers. Negative integers are not natural numbers while positive integers are natural numbers.
- Irrational numbers will Always be real numbers.
Real numbers consist of both irrational and rational numbers. So, all irrational numbers are real numbers.
- Rational numbers will Never be irrational numbers.
Rational numbers and irrational numbers are two different types of real numbers.
- Rational numbers will Sometimes be integers.
Not all rational numbers are integers. there are some rational numbers that are not integers while some rational numbers are integers.

Answer:
Its C
Step-by-step explanation:
All you have to do is divide 90.2 by 11
1) the vertex of a parable is given for two points, ( -b/2a, -b2-4ac/4a)
2) Now substitute the values in the equation
x = - (-8)/2(-2) = 8/ -4 = -2
y = -(8^2-4(-2)(1)/ 4(-2) = -(64-8) /-8 = 56/8 = 7
v(-2,7)
Answer:
The visitor should run 13 km due west from the tent
Step-by-step explanation:
Here we have;
Location of island = 3 km North of point on shoreline
Location of tent = 13 km East of point on shoreline
Running speed of visitor = 8 km/h
Swimming speed = 1 km/h
Distance of island from tent = 
Since, time = distance/speed, it will take 13.34/1 hours or 13.34 hours to swim directly to the island.
However if the visitor first runs to the closest point on the shoreline to the island, then swims across to the island, it will take;
13/8 Hr + 3/1 hr = 37/8 hours or 4.625 hours only.
Therefore, to minimize the time it takes to reach the island, the visitor has to run 13 km west of the tent to first get to the closest point of the shoreline to the island before swimming across to the island.
