Answer:
6
Step-by-step explanation:
this question is basically asking you to find the HCF of 30 and 36
step 1 : draw prime factor tree diagrams and write the numbers out as the product if their prime factors
step 2: multiply the prime factors they have in common
30 = 2 x 3 x 5
36 = 2 x 2 x 3 x 3
HCF = 2 x 3 = 6
Answer:
He must lose 4.4 pounds per week.
Step-by-step explanation:
Buffalo Bill currently weighs 202 lb. He wants to weigh 180 lbs for his reunion.
This means that he needs to lose 202 - 180 = 22 lb.
35 days from today.
Each week has 7 days. So this is 35/7 = 5 weeks from now.
How many pounds per week must he lose?
22 pounds in 5 weeks, that is 22/5 = 4.4 pounds per week.
Answer:
natural numbers
Step-by-step explanation:
As it is for any sequence, the domain of term numbers (n) is the positive integers, the natural numbers.
_____
When the common ratio is positive, the expression for the n-th term can be evaluated for non-integer values of n. In the context of "term number n", that makes no sense, but you can do it.
When the common ratio is negative, you can also evaluate the expression for the n-th term for non-integer values of n. In such cases, you get a complex number result. That, too, makes no sense in the context of a sequence, but you can do it.
In general, the domain of any "n' that represents something being counted, the domain of n will be the counting numbers.
