The given sequence;–3.2, 4.8, –7.2, 10.8, is a geometric progression common ratio of -1.5.

<h3>What is a geometric series?</h3>

When all the terms of a geometric sequence are added, then that expression is called geometric series.

The given sequence ;

–3.2, 4.8, –7.2, 10.8, …

The common ratio

= -4.8/ 3.2

= - 1.5

The terms having a common ratio of -1.5 best describe the relationship between the successive terms in the sequence of the terms.

Answer:

53 1/3% for the first answer, and 33 1/3% increase for the second answer

Step-by-step explanation:

Ok, lets start up witht eh first question.

We need to find the percentage of studens that find math the be their favorite subject in elementary school.

We know that there are 15 kids in total.

We specificly see that 8 of those kids like math the most.

To find percentage, divide 8 by 15.

Using a calculator you should find 53 1/3% of the students found math to be their favorite subject.

Next we need to find the percentag eof change that history is over elementary school to high school.

This might sound confusing, but this is basically just a change of 3 students to 4 students.

To find percentage, just divide 3 by 4:

This gets you 33 1/3%

Hope this helps!

d = dimes

q = quarters

d+q = 38 coins

q=38-d

0.25q + 0.10d=6.95

0.25(38-d)+0.10d=6.95

9.5-0.25d+0.10d=6.95

-015d=-2.55

d=-2.55/-0.15 = 17

q=38-17 =21

21*0.25 =5.25

17*0.10 = 1.70

5.25+1.70 = 6.95

she had 21 quarters and 17 dimes

Can u help me answer this I’m so stuck

Slav-nsk [51]

Answer:

I learned a great formula for repeating decimals.

OK! Let's get started. For each decimal spot that is recurring, it is put over a 9, rather than a 10.

In your case, 0.142 would be 142 over 3 9s.

142/999 cannot be simplified.

Therefore, 142/999 is our answer.

Since the repentant is over only one digit, we have to solve another way.

We can represent it as "x"

10x = 5.66.... - x = 0.56.....=5.1

9x = 51/10

51/10/9 = 51/90 = 17/30 as our answer.

We can solve this next one the same way:

100x = 3.44444 - x = 3.41

999x = 341/100

341/100/999 = 31/900 as our answer.

Now! 1.52 can be solved the same way.

In doing so, we achieve the answer 151/99 as our answer

This one can be done the same way as well. I'll give you the answer, but next time try to solve it for yourself!

179/495 is our answer.

Now, you asked for 0.004 as a fraction.

That is equivalent to 4/999 as our answer.

Note: This is because each 0 can be counted as a 9, increasing in order. (i.e., over 100 is over 99 over 1000 is over 999 over 10 9)

There are 4 roads leading from Bluffton to Hardeeville, 6 roads leading from Hardeeville to Savannah, and 5 roads leading from

Dmitrij [34]

Answer:

120 ways.

Step-by-step explanation:

From the given information:

Total number of roads leading from Bluffton to Hardeeville = 4

Total number of roads leading from Hardeeville to Savannah = 6

Total number of roads leading from Savannah to Macon = 5

We need to find the total number of ways to get from Bluffton to Macon.

Total number of ways to get from Bluffton to Macon = $4\times 6\times 5= 120$

Therefore, there are 120 required number of ways to get from Bluffton to Macon.
