Answer:
a = 2 , r = 5
Step-by-step explanation:
The n th term of a geometric progression is
= a![r^{n-1}](https://tex.z-dn.net/?f=r%5E%7Bn-1%7D)
where a is the first term and r the common ratio
Given the 4 th term is 250, then
ar³ = 250 → (1)
Given the 7 th term is 31250, then
a
= 31250 → (2)
Dividing the 2 equations gives
=
, that is
r³ = 125 ← take the cube root of both sides
r =
= 5
Substitute r = 5 into (1)
a × 5³ = 250, that is
125a = 250 ( divide both sides by 125 )
a = 2
Find volume of each bill and each room
v=lwh
vbill=6.14*2.61*0.0043=0.06890922 in^3
must convert room dimientions to inches
25*12=300in
23*12=276in
15*12=180in
Vroom=300*276*180=14904000in^3
now 1 billion bills
move decimal place over 9 places to right
1 million bills takes about 68909220 in^2
how many rooms to fit them all?
vbillionbills/v1room=number of rooms needed=
68909220/14904000=4.623
round to 1 deicmal
4.6 rooms needed (actually, it would be 5 since you can't use the 0.4 room left over very efficiently)
answer is 4.6 rooms
392 / 500 double and take one decimal place to see percentage
52/500
56/500 e.g. 56*2 = 112 now take 1 decimal so it is 11.2%
now divide each by 20
