Answer: 7+0.7+0.05
Since 7 is in the ones place it goes in front of the decimal. .7 is in the tenth place because it's behind the decimal. .05 is also behind the decimal so it's in the hundredths place.
Answer:
a8 = 512.
Step-by-step explanation:
This is geometric sequence with common ratio r = 2 and first term a1 = 4.
nth term = a1 r^(n-1)
So a8 = 4 2(^8-1)
= 4 * 2^7
= 4*128 = 512.
Answer:
4.5
Step-by-step explanation:
4n - 6 = 12

4n = 18
divide by 4
4/4n = 18/4
n = 4.5
