a metal bar weighs 8.15 ounces. 93% of the bar is silver. how many ounces of silver are in the bar? (round to the nearest thousa
2 answers:
Answer: 7.560 ounces
Step-by-step explanation:
Given : The weight of a metal bar = 8.15 ounces
Also, it is given that : 93% of the bar is silver.
We can write 93% as 0.93 [To convert percent into decimal or fraction , we divide it by 100.]
Now, the amount of silver in the metal bar = 93% of 5.15 ounces
Replace 'of' by '×' and '93%' by '0.93' , we get
The amount of silver in the metal bar =
Hence, there are 7.560 ounces of silver in the metal bar.

Answer:
You gave the explicit form.
Step-by-step explanation:
You gave the explicit form.
The recursive form is giving you a term in terms of previous terms of the sequence.
So the recursive form of a geometric sequence is and they also give a term of the sequence; like first term is such and such number. All this says is to get a term in the sequence you just multiply previous term by the common ratio.
r is the common ratio and can found by choosing a term and dividing by the term that is right before it.
So here r=-3 since all of these say that it does:
-54/18
18/-6
-6/2
If these quotients didn't match, then it wouldn't be geometric.
Anyways the recursive form for this geometric sequence is
