Answer:
You didn't give the geometric sequence in question.
But to find the nth term of a geometric sequence, use the formula
Sn = ar^(n - 1)
Where a is the first term of the sequence
r is the common ratio of the sequence.
Example: To find the nth term of the geometric sequence
1/2, 1/4, 1/8, 1/16, ...
Here, a = 1/2
r = 1/4 ÷ 1/2 = 1/8 ÷ 1/4 = 1/16 ÷ 1/8 = 1/2.
Sn = (1/2)(1/2)^( n - 1)
Apply this method to the sequence you were given, it will be helpful.
Answer:
12 = 12
Step-by-step explanation: equal integer theorem.
Answer:
C
Step-by-step explanation:
If 9 members paid on the first day, this means they did not pay on the third day
The remaining people (everyone but the 9) paid on the third day
Therefore we must subtract to find out how many members paid on the third day
22 - 9 = 13
Each of the 13 members paid $12.80 which means we must multiply
13 × 12.80 = 166.40
In total, the grocery store collected $166.40 on the third day of the month
Answer:
1/18
Step-by-step explanation:
1/6 * 1/3
1 *1 = 1
6 * 3 = 18
1/18
Answer:
110 Degrees
Step-by-step explanation:
The sum is when different numbers are added.
When all angles are added it adds up to 180 Degrees for any triangle.
Triangles have three sides and two are given as 50 Degrees and 20 Degrees.
There is one angle remaining.
50 Degrees + 20 Degrees = 70 Degrees
Therefore, the last angle must be 110 Degrees. (180-70)
