You could put into a calculator OR
a handy trick with 10's (10, 100, 1000, etc.) is that you take the number of 0's in the number and move the decimal to the right that many times!

7.5 x 1000 = 7,500
(as there are 3 zeros in 1000, you move the decimal to the right by 3)

Answer:

B. 1

Step-by-step explanation:

Multiply the first term by $x^a$ , the second term by $x^b$ , the third term by $x^c$ .

<u>The first term becomes:</u>

$x^a/(x^a+x^b+x^c)$

<u>The second term becomes:</u>

$x^b/(x^a+x^b+x^c)$

<u>The third term becomes:</u>

$x^c/(x^a+x^b+x^c)$

<u>Their sum is:</u>

$(x^a+x^b+x^c)/(x^a+x^b+x^c) = 1$

Correct choice is B

What is the 32nd term of 311, 305, 299

nata0808 [166]

Answer:

503

Step-by-step explanation:

For an arithmetic sequence, the n-th term is found by

$a_n = a_1 + (n - 1)d$

To find $d$ (the common difference) we can simply subtract one of the terms by the last, for example:

$d = 299 - 305 \\d = -6 \\$

The common difference must be the same throughout the entire sequence, so we can do it once more just to be sure:

$d = 305 - 311\\d = -6$

We also have to know that $a_1$ stands for the first term of the sequence, which in this case is 311.

Now that we know this, let's find the 32nd term

$a_{32} = 311 + (32 - 1)-6\\a_{32} = 311 + 192\\a_{32} = 503$

Good luck!
