Answer:
17.7
Step-by-step explanation:
This figure is a pentagon - a shape with 5 sides. In a pentagon, the figure's angles add to 540.
100 + 7x-4 + 3x + 23 + 9x - 6 + 90 = 540
190 +19x + 13 = 540
203 + 19x = 540
19x = 337
x = 17.7
Answer:
1/4(8/3+9)-3
Step-by-step explanation:
1/4(8/3+9)-3
The number of arrangements is an illustration of permutations.
The number of arrangement is 5040
The given parameter is:
<em />
<em> --- number of days</em>
<em />
<em> --dinners for 7 days</em>
<em />
So, the number of different arrangement is
Substitute known values
Hence, the number of arrangement is 5040

First of all, find the first number more than 100 that can divided by 9, and it's 108 (we'll call it as 'a') then, find the number less than 2000 that can divided by 9, it's 1.998 (we'll call it as 'Un')
Un = a + (n-1).b
1998 = 108 + (n-1).9
1998 = 108 + 9n -9
1899 = 9n
211 = n
and the total is
Sn = n/2 (a+un)
s211 = 211/2 (108+1998)
= 222.183
Hey there!
Here is your and for this question.
Answer: n=-7
All you have to do is move all of your terms that are not containing the variable n to the right side of the equaion.
