If the population of a certain town decreases by 4.5% each year, we form a geometric sequence with first term equal to 8,500 and r equal to 0.955.

<span>(a)   </span>The equation is then,

<span>                                          An = (8,500)(0.955)^n</span>

Where n is the number of years.

 

<span>(b)   </span>Substituting 7000 to An and solving for n,

7000 = 8500*(0.955)^n

<span>            The value of n from the equation is 4.2 years. </span>

The answer is 90/91. 6 1/2 - 7/8 divided by 5 11/16. Turn 6 1/2 and 5 11/16 to an improper fraction. 6 1/2= 13/2. 5/11= 91/16. Then you have to get each fraction to have equal denominators. All of them can have a denominator of 16. So you times everything to get a denominator of 16. 13/2= 104/16. 7/8=14/16. 91/16 stays the same because the denominator is already 16. Next you subtract 104/16 and 14/16 and get 45/8.( because you need to put it in simplest form.) Lastly you divide 45/8 by 91/16 and get 90/91.

You are making several purchases from the b-better electronics store. You can buy from this store online or in a physical store.
alexandr402 [8]

Answer:

Online Ordering is better.

Step-by-step explanation:

So you now that you save 20% if you to physical store and you save $20 if you go to the online store.

Say you are spending 100 dollars at the store to make it easy. 20% of one hundred is $20 so that is the same amount of money.

Now let’s look at the taxes and shipping so at the physical store you have to pay taxes no matter what but online you only do it if you purchase is less than $75 and we have $80 ($100–$20=$80) so at the physical store you have some amount of Mandy that is more than $80 because of taxes but if you buy online it will be exactly $80.
