Answer:1695.75
Step-by-step explanation:
We know that there are 7 days in a week. Since 57 people rent skates each day, we know that 57*7=399 skates are rented each week. Since one skate cost 4.25, we know that 399*4.25 is the cost, which is 1695.75. (If you are not allowed to use a calculator, you can do 400*4.25-4.25, to make it easier to compute)

Step-by-step explanation:
The common difference d of an arithmetic sequence is
d = 
- 
= 
-
Substitute in values and solve for k, that is
5k - 1 - 2k = 6k + 2 - (5k - 1)
3k - 1 = 6k + 2 - 5k + 1
3k - 1 = k + 3 ( subtract k from both sides )
2k - 1 = 3 ( add 1 to both sides )
2k = 4 ⇒ k = 2
--------------------------------------------------------
The n th term of an arithmetic sequence is
= + (n - 1)d
= 2k = 2 × 2 = 4 and
d = 5k - 1 - 2k = 3k - 1 = (3 × 2) - 1 = 5
Hence
= 4 + (7 × 5) = 4 + 35 = 39
<h2>Answer:
</h2><h2>
Techno ∩ (European ∩ Dutch)'</h2>
Step-by-step explanation:
According to sets theory ;
Intersection ( ∩ ) - e.g (European ∩ Dutch) represents both European and
Dutch , while (European ∩ Dutch)' represents neither
European nor Dutch .
Union ( ∪ ) - e.g (European ∪ Dutch) represents either European or Dutch .
So , Techno ∩ (European ∩ Dutch)' represents set notation of techno musics that is neither European nor Dutch .
