100 - 80% = 20 %
20% = $416
416 x 5 = $2080 = 100%
The volume of the prism shaped fish tank is: 408 in.³.
<h3>What is the Volume of a Prism?</h3>
Volume of prism = base area × height of prism.
The fish tank is a prism having a height of 8 inches. To find its volume, find the base area, which is the area of the composite figrue given.
Thus:
Base area = area of rectangle + area of triangle = (length × width) + (1/2(base × height).
Given:
- Length = 7 in.
- Width = 6 in.
- Base = 6 - 3 = 3 in.
- Height = 13 - 7 = 6 in.
Therefore:
Base area = (7 × 6) + 1/2(3 × 6)
Base area = 51 in.²
Volume of the prism shaped fish tank = 51 × 8 = 408 in.³.

Answer:
5120
Step-by-step explanation:
The recursive formula ...
a[1] = 5
a[n] = 4·a[n-1]
defines a sequence with first term 5 and common ratio 4. The explicit formula for a term in this sequence can be written ...
a[n] = 5·4^(n-1)
We can use this formula to find a[6]:
a[6] = 5·4^(6-1) = 5·1024
a[6] = 5120
_____
If you like, you can write out the first 6 terms of the sequence using the recursive formula. Each is 4 times the previous.
