Volume of 1st aquarium = 11 * 13 * 14 = 2002
volume of 2nd aquarium = 21 * 14 * 30 = 8820
if 5 minutes = 2002
1 minute = 2002\5 = 400.4
minutes to fill the 2nd aquarium is 8820/400.4 = 22.028(approximately)
Answer:
side = 2x - 8
Step-by-step explanation:
An equilateral triangle has 3 equal sides.
The perimeter is 3 times one side
In this case P = 6x - 24
Side = p/3 = (6x - 24)/3
Side = 2x - 8
The first three terms of the sequence defined by the recursive formula are 2, -7/2 and -3/2
Given:
where,
n = number of terms
First term, a1 = 2
Second term, a2
a2 = {(2 - 1)/ 4} - 2
= 1/4 - 2
= (1-8) / 4
= - 7/4
Third term, a3
= {(3-1) / 4} - 2
= 2/4 - 2
= 1/2 - 2
= (1-4) / 2
= -3/2
Therefore, the first three terms of the sequence defined by the recursive formula are 2, -7/2 and -3/2
