12/15 i hope this helps , 20 goes into one hour 3 times so i multiplied 4/5 x 3
Your answer is 18 :)
work:
pi(2)d
pi(72)
72/2=36=d
2r=d
36/2=18=r
Answer:
he most important subsets of the set of real numbers include the rational and the irrational numbers. The set of rational numbers can be divided into further subsets, including the natural numbers, the whole numbers and the integers.
Step-by-step explanation:
The explicit rule for given sequence is:
Further explanation:
We have to determine first of all if the sequence is arithmetic or geometric.
- If the difference of two consecutive terms is same then the sequence is arithmetic sequence
- If the ratio of two consecutive terms is same then the sequence is geometric sequence
Given sequence is:
12,22,32,42
The common difference is 10 which is same for all consecutive terms. So the sequence is an arithmetic sequence.
The general formula for arithmetic sequence is:
Putting the values of a1 and d
The explicit rule for given sequence is:
