Answer:
Well there aren't any options but a number line pointing right with the circle being empty (For example, ○) on the point -2.
Answer:
The answer is 12 because 2x is just 8 and 2y is just 6 so add that and get 14 then subtract 2.
Step-by-step explanation:
Three hundred and eightteen and twentyfive meters
Answer:
14 is a positive integer, then it belongs to the set of natural numbers.
1 and 5/9 are rational numbers. The second is already a fraction and the first one, 1, is a natural number, but all the natural numbers can be written as the result of a fraction. For example: 1=6/6.
About the last number, I don't know if it's written correctly. That should be pi maybe, that is 3.14159.... In that case it's an irrational number.
Irrational numbers are all those real numbers that are not rational.
In general you have that:
ℕ ⊂ ℤ ⊂ ℚ ⊂ ℝ
ℕ. Natural numbers. It's the "smallest" one.
ℤ. Integers. Made with positive and negative natural numbers. Includes the natural numbers then.
ℚ. Rational numbers. Everything that can be written as a fraction. Includes both ℕ and ℤ.
ℝ. Real numbers. Any kind of number, fraction or not.
Answer:
A
Step-by-step explanation:
The bottom side of the smaller rectangle is marked 10, and the bigger one is marked 20. 20÷10=2, making this a 2:1 scale. Simply multiply the 8 on the right of the smaller rectangle by 2 and you'll get 16, the answer for the similar rectangle.
