6 - 34 + 96 - 384 +...
a 1 = 6 , a 2 = a 1 * ( - 4 ) , a 3 = a 2 * ( - 4 ), a 4 = a 3 * ( - 4)...
a 5 = - 384 * ( - 4 ) = 1,536
a 6 = 1536 * ( - 4 ) = - 6,144
a 7 = - 6,144 * ( - 4 ) = 24,576
This is a sum of a geometric sequence:
S 7 = 6 - 24 + 96 - 384 + 1,536 - 6,144 + 24,576 = 19,662
Another way to solve this:
S 7 = a 1 * ( r^n - 1) / ( r - 1 ) = 6 * (( - 4) ^7 - 1 )/ (- 4 - 1)=
= 6 * (-16,385) / (-5 ) = 19,662
Huh, this is presented pretty interesting to me.
To start with, if you actually had no idea what the answer to this question was, you wouldn't pick B or C because x has to be close to 91°. In this particular quadrilateral, it's especially important that we focus on the fact, "x - 15." This means that x has to be higher initially to be subracted to equal 91, or the opposite angle.
In order to subtract to 91, the answer would have to be 106, or D. This is a hunch, but I have a suspicion that angle B and D are going to be the same, being that their on opposite sides of the figure.
Hope this helps! If you have further questions, let me know.
Answer:
<u>, where "n" is number of objects per page.</u>
Step-by-step explanation:
<em>The amount of objects each page could hold is given by dividing the amount of objects that you have, by the number of pages. </em>
<em>• Let the number of objects per page be "n".</em>
<em>Then, the equation that gives us the number of objects for each page, in such way that we have an equal amount of objects per page is:</em>
.
Answer:
2/6 is the answer you are looking for.
Step-by-step explanation:
The is 1 tile that is needed and two others that aren't so you would have 1/3 which means one out of three outcomes. And you have two spins which makes you multiply the fraction by two. Giving you 2 out of 6 outcomes.
Eight ones = 8
Six tens= 60
60 + 8 = 68
