You can use your calculator to divide it out and find that

or, you can make use of your knowledge of the decimal equivalent if 1/11 (=0.90909...) and multiply that by -8 to get -0.727272... as above.
25^(n-3)=5^(n+8)
Remember: 25=5²
Therefore:
5^[(n-3)²]=5^(n+8)
5^(2n-6)=5^(n+8)
Then:
2n-6=n+8
2n-n=8+6
n=14
Answer: n=14
Hello from MrBillDoesMath!
Answer:
9
Discussion:
Solution 1:
Distance between two points (x1, y1), (x2,y2) is given by the formula
sqrt( (x1-x2)^2 + (y1-y2)^2). In our case this becomes
sqrt( (0-0)^2 + (12 -3)^2 ) =
sqrt( 9^2) =
9.
Solution 2:
Note points D and E both have x = 0 so segment DE is a vertical segment. The length is simply the difference of the y coordinates: 12- 3 = 9 as before.
Thank you,
MrB
Answer:
its the 4th one . The one all the way to the bottom
Step-by-step explanation:
N x 100 = n%
An example:
<span>12 is 20% of 60. In order to get 12 percent of 60, all you need to do is to divide 12 with 60. To get the percent means to get the parts of 100. To get it in the form of percent, just multiply the quotient by 100. 12/60=.2 x 100 = 20% .</span>
