The sum of the first 12 terms of a geometric sequence with 10 as the first term and a common ratio of 0.3 is __________.

BaLLatris [955]

Answer: 14.2638366937

Step-by-step explanation:

A geometric sequence is a sequence in which each term is multiplied by a number, called the common ratio, to get the next term.

So, if the first term of the geometric sequence is 10 and the common ratio is 0.3, the sequence would be 10, 0.3(10), 0.3 x 0.3 x 10... and so forth. This becomes:

10, 3, 0.9, 0.27, 0.081, 0.00243, 0.00729, 0.002187, 0.0006561, 0.00019683, 0.000059049, 0.0000177147...

You add these first 12 terms to get 14.2638366937.

An angle measures 47.2° less than the measure of its supplementary angle. What is the measure of each angle? on ixl

SVEN [57.7K]

Answer:

The measure of one angle is $113.6^o$ , and the measure of the other one is $66.4^o$

Step-by-step explanation:

Recall that supplementary angles are those whose addition renders $180^o$

We need to find the measure of two such angles whose difference is precisely $47.2^o$ .

Let's call such angles x and y, and consider that angle x is larger than angle y, so we can setup the following system of equations:

$x+y=180^o\\x-y=47.2^o$

We can now solve this by simply combining term by term both equations, thus cancelling the term in "y", and solving first for "x":

$x+y=180^o\\x-y=47.2^o\\\\2x=180^o+47.2^o\\2x=227.2^o\\x=113.6^o$

So, now we have the answer for one of the angles (x), and can use either equation from the system to find the measure of angle "y":

$y=180^o-x\\y=180^o-113.6^o\\y=66.4^o$
