Well the formula:
V = Bh
54= 3*w*8
54= 24w
24w=54
w= 54/24
w= 2.25
Answer:
<u>a(n)=80*(9/10)^(n-1)</u>
Step-by-step explanation:
I think u r confused
this sequence is geometric not arithmetic
HOw we know that ??
when we get a common difference <u>that must Be equal </u>
d=72-80=-8 not equal to d=64.8-72=-7.2
So it is not arithmetic
but when we get the common ratio that also must <u>be equal </u>
r=72/80=9/10 equal to r=64.8/72=9/10
So it is geometric
By using this equation:
a(n)=a*r^(n-1)
and we have <u>a=80 , r=9/10</u>
Then <u>a(n)=80*(9/10)^(n-1)</u>

Answer:
5,540
Step-by-step explanation:
think you just subtract
Well I Think it is 4 because it says round off
Total amount of money: 175
Owen's amount: x
Ethan's amount: x + 33
(x) + (x + 33) = 175
2x + 33 = 175
2x = 142
x = 71
Owen's amount: $71
Ethan's amount: $104
Hope this helps!! :)
