Find the common ratio of the geometric sequence: −320,80,−20,5,…

Answers

Answer 1

Answer:

With geometric sequences, if you divide a term by the term before it you'll get the common ratio. That's how they are all constructed, and in this problem:

$(80)/(-320)=-(1)/(4)$

So -1/4 is our common ratio.

Answer 2

Answer:

The common ratio of the geometric sequence −320, 80, −20, 5,… is -1/4 or -0.25.

What is a sequence?

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have a geometric sequence:

−320, 80, −20, 5,…

As we know, the geometric sequence or progression follows a certain rule of arithmetic.

The common ratio = second term/first term or

First term = -320

Second term = 80

= 80/(-320)

= -1/4

The common ratio = -1/4 or -0.25

Thus, the common ratio of the geometric sequence −320, 80, −20, 5,… is -1/4 or -0.25.

What is 84.5% as a decimal

Answers

To convert ANY percent into decimal form ALL we need to do is DIVIDE the percent by 100. So lets do that:-

84.5 ÷ 100 = 0.845

So, 84.5% as decimal is 0.845.

Hope I helped ya!!!!!!!

0.845 because A. I've done this before and B. because if you have a percentage sign you have to add the decimal at the front (i think don't quote me)

If 8 widgets equal 4 curlicues and2 curlicues equal 3 goof-ups,then
16 widgets equal how many goof-ups?

Answers

so 8w=4c and 2c=3g. divide the first equation by 2 and you get 4w=2c. merge the two equation give you 4w=2c=3g, or 4w=3g. multiply 4 on both sides give you 16w=12g. So 16 widgets equal how 12 goof-ups?

first you put the numbers in place of the letter so it looks like 3(5)-2(3)
now you do 3x times 5 which =15x and do -2y times 3 and you get -6y now it should be this 15-6=9
