IT IS A NUMBER LINE SO IT IS JUST BASIC ADDITION AND SUBTRACTION.
Answer:
$ 12.6 / h
Step-by-step explanation:
5% of 12 = 0.05 * 12 = 0.6
Now adding it to the amount he makes, since it is a raise:
0.6 + 12 = 12.6 $ / h
Another (and faster) way to calculate it:
1.05 * 12 = 12.6
Answer:
y=44
Step-by-step explanation:
1/2y=22
y=22/(1/2)
y=(22/1)(2/1)
y=44/1
y=44
Answer:
{ x : x = 2^n -1 , n ∈ N}
Where N is the set of natural numbers
Step-by-step explanation:
Mathematically, we can rewrite each term in the set as follows;
1 = 2^1 - 1
3 = 2^2 -1
7 = 2^3 -1
15 = 2^4-1
31 = 2^5-1
63 = 2^6 -1
so we can conclude that the nth term is 2^n -1
So writing this in set builder notation, we have;
{ x : x = 2^n -1 , n ∈ N}
Where N is the set of natural numbers
