Answer:
8th term of geometric sequence is 312500
Step-by-step explanation:
Given :
and common ratio (r) = 5
We have to find the 8th term of the geometric sequence whose
and common ratio (r) = 5
Geometric sequence is a sequence of numbers in which next term is found by multiplying by a constant called the common ratio (r).
......(1)
where
is nth term and a is first term.
For given sequence
a can be find using
and r = 5
Substitute in (1) , we get,
Thus, 8th term of the sequence denoted as 
Substitute n= 8 in (1) , we get,

Thus 8th term of geometric sequence is 312500
Answer:

Step-by-step explanation:
<h2>
This problem bothers on the mensuration of solid shapes.</h2>
In this problem we are to find the volume of the first cylinder and compare with the second cylinder.
Given data
Volume v = ?
Diameter d=
?
Radius r = 
Height h= 
we know that the volume of a cylinder is expressed as

Substituting our given data we have

The first cylinder as a volume of 
The change in volume is 
percentage = 

%
Answer:
A. 5 1/2 and D. 11/2
Step-by-step explanation:
Make improper fraction
8*1+3=11/8
Solve by multiplying:
4*11/8
44/8
Simplified is 11/2
We can turn it back into a mixed number
2*5+1=11 so 5 1/2
