Answer:

3.70

Step-by-step explanation:

9 divided by 2.43

To divide decimal numbers we need to remove the decimal point

$\frac{9}{2.43} =\frac{9 \ times \ 100}{2.43 \ times \ 100} =\frac{900}{243}$

Now use long division to divide the numbers

3.70370

--------------------------------

243 900

729

---------------------------(subtract)

1710 (add decimal point at top)

1701

---------------------------

900 (add 0 at top)

729

---------------------------(subtract)

1710 (add decimal point at top)

1701

---------------------------

So answer is 3.70

Just do normal division, just like ignore the decimal point. for a moment once you got your answer bring back the decimal point back up to your answer. You would get 0.27 as your answer.

Answer:

Hello There!!

Step-by-step explanation:

You order the number on the list but they are already in order so pick the middle number but in this case there are 2,so you add 33 with 34 which equals 67.Then you divide 67 by 2 which is 33.5. Therefore,33.5 is your answer.

hope this helps,have a great day!!

Find the sum of the first 20 terms of the arithmetic sequence 4, -4, -12, -20

Vsevolod [243]

Answer:

The sum of the first 20 terms is -1440.

Step-by-step explanation:

We want to find the sum of the first 20 terms of the arithmetic sequence:

4, -4, -12, -20...

The sum of an arithmetic sequence is given by:

$\displaystyle S=\frac{k}{2}(a+x_k)$

Where k is the number of terms, a is the initial term, and x_k is the last term.

Since we want to find the sum of the first 20 terms, k = 20.

Our initial term a is 4.

Our last term is also the 20th term as we want the sum of the first 20 terms.

To find the 20th term, we can write an explicit formula for our sequence. The explicit formula for an arithmetic sequence is given by:

$x_n=a+d(n-1)$

Where a is the initial term, d is the common difference, and n is the nth term.

Our initial term is 4. From the sequence, we can see that our common difference is -8 since each subsequent term is eight less than the previous term. Therefore:

$x_n=4-8(n-1)$
