Answer:

Answer: arithmetic

Step-by-step explanation:

An arithmetic sequence is when you ADD a number (d) to the previous number to create the next numbers in the sequence.

A geometric sequence is when you MULTIPLY a number (r) to the previos number to create the next numbers in the sequence.

$n_1 = 3+(1)a\nn_2=3+(2)a\nn_3=3+(3)a$

Notice that "a" is added to each term in the sequence.

Write the ratio in three different formats: In a year, there are 4 months that have 30 days. Write a ratio of the months with 30 days to the months with other than 30 days. A.1 to 3, 1:3, 1/3B.1 to 2, 1 :2, 1/2C.2 to 1, 2:1, 2/1
D.3 to 1, 3:1, 3/1

Answers

This problem is an example of ratio and proportion. A ratio is a comparison between two different things. You are given 4 months that have 30 days. You are required to get the ratio of the months with 30 days to the remaining months that have a different number of days. First, you will get the ratio as 4/30 = 2/15. Assuming that the other months also has 30 days. Then the second ratio is 8/30 = 4/15. Multiply 2/15 to 15/4 you will get ½. Other forms of this is 1:2 or 1 is to 2. The answer is B.

so find the amount of months that don't haave 30 days
12 months total
4 have 30 days
12-4=8
so the ratio of months that have 30 days to the months that do not havve 30 days is 4 to 8 or 4:8
this can be simplified like a fraction
4:8 4/8=1/2
ratio is
1 to 2, 1:2, 1/2

answer is B
