How to find the rule for the nth term of a geometric sequence with changing common ratio?

Hmmm... a geometric sequence MUST have a fixed common ratio. If it is changing, then the sequence you are looking at might not be a geometric sequence at all. We'd need to see an example to be sure.

Help. IM SO LOST ON THIS! ;(

Answer:

1. 4\frac{2}{3}

Step-by-step explanation:

For question 1, you need to know the ratio between the recipe and the amount in question.

So if in the recipe, it says it uses 3/4 cup of diced ham, and the question uses 1 cup of diced ham, you can divide 1 by 3/4 to get 4/3. This is how many times bigger the amount used in the question than the recipe.

Then it asks for how many cups of potatoes, to do this, you look at the recipe and how many potatoes it uses: 3.5 cups

To solve it then, you just do 3.5 x 4/3 to get 4\frac{2}{3} cups of potatoes

There's your answer.

What is 15 increased by 60%
vazorg [7]
What is 15 increased by 60 percent? Let's work it out!

First, you must know what 60 percent of 15 is.

<u>60 percent of 15
</u>   15 times .60 
<u />equals
9.

So 60% of 15 is 9.


<u /><u>Increased</u> is a word which<u> means added</u>.

So, 15 plus 9 (15+9) is 24.

Final Answer = 24.




Hope I could help!

<span>a.       </span>Let m = be the number of miles driven

Cost of NYC rentals: 525 + 0.21m

Cost of Metro Trucks: 585 + 0.13m

 

<span>b.      </span>525 + 0.21m = 850

0.21m = 325

M = 1,548 miles

<span>c.       </span>Initial cost for NYC rentals = $525

Initial cost for Metro Trucks = $585

<span>d.      </span>NYC rentals: 525 + 0.21 (500) = $630

Metro Trucks rentals: 585 + 0.13 (500) = $650

<span>e.      </span>525 + 0.21m = 585 + 0.13m

0.21m – 0.13m = 585 – 525

0.08m = 60

m = 750 miles
