How many terms are there in a geometric series if the first terms is 2, the common ratio is 4, and the sum of the series is 2,73

arsen [322]

The sum of n terms of a geometric series is given by
$S_{n}=a_{1}\dfrac{r^{n}-1}{r-1}$

Substituting the given numbers, you have
$2730=2\dfrac{4^{n}-1}{4-1}\\\\2730\dfrac{3}{2}=4^{n}-1\\\\4096=4^{n}\\\\\dfrac{\log(4096)}{\log(4)}=n=6$

There are 6 terms in the series.

Tickets to a football game cost $15.00 each including tax and a bag of popcorn cost $2.25 and a soda cost $1.75 Xavier has $350.

adoni [48]

Answer:

18 (full answer: 18.4210526316)

Step-by-step explanation:

<em>I LOST MY ANSWER RIGHT WHEN I WAS ABOUT TO FINISH DUE TO BRAINLY ROBOT DETECTION </em>

This question seems incomplete. I dont know the tax, and what he wants to do with the $350, so I'll just work without them.

I'm going to assume that he wants to buy extra tickets, popcorn, and soda with the extra money.

1. add $15, $2.25, and $1.75

2. 15.00+2.25+1.75= 19.00

3. divide 350 by 19

350/19= roughly 18.42

So, Xavier can buy 18 tickets with food and drinks.
