Rational number are numbers which can be expressed in a ratio of two integers. Both numerator and denominator are whole numbers<span>, where the denominator is not equal to zero.</span>
An irrational number<span> on the other hand is a </span>number which cannot be expressed in a ratio of two integers. However there are similarities between them. For example: the product of both irrational numbers of born rational numbers can be rational number, both irrational and rational numbers can be negative and positive, and both can be expressed as a fraction.
40-30=10 minutes more per day x 31 days = 310minutes in a month with 31 days.
Answer:
The snail will reach the top of the coconut in 18 hours.
Step-by-step explanation:
If the snail will climb 2 meters in 1 hour but it will slip down one meter for every 2 meters climbed, then the distance traveled will be:
Since in 1 hour, it climbs 2 meters minus 1 meter, the time in which the snail will reach the top is:
Therefore, the snail will reach the top of the coconut in 18 hours.

Diameter = 8 cm
radius = diameter/2 = 4 cm
A = pi * r^2
A = pi * (4 cm)^2
A = 16pi cm^2
