Answer:
It is contained in the set of natural numbers, whole numbers, integers, and rational numbers, but it is not contained in the set of irrational numbers.
Step-by-step explanation:
The given number can be expressed as:
Then is contained in all the set an exception of irrational and complex numbers.
The set of natural numbers is:
Then 15
The set of whole number is the same but with 0, then also is inside that set.
The set of integers is:
And at the same time contain the set of whole and natural numbers then 15 is also in the integers.
And the set of rational numbers is:
And at the same time contain the set of whole, natural numbers and integers then 15 is also in the rational numbers.
Now 15 is not an irrational number because don't have a infinity growth of numbers after the decimal point and neither complex because isn't in the options.
Answer:
1.5 hours
Step-by-step explanation:
we know that
1) Martha can paint a room in 2 hours
so
Martha can paint the 100% of the room in 2 hours
Find out what percentage of the room she can paint in an hour
using proportion
2) Jamie can paint a room in 6 hours
so
Jaimie can paint the 100% of the room in 6 hours
Find out what percentage of the room she can paint in an hour
using proportion
3) In one hour Martha and Jamie can paint
so
using proportion
Find out how long will it take them to paint the 100% room together
Answer:
