Answer:
There are 9 terms, and the common difference is 11.
Step-by-step explanation:
The sum of the first n terms of an arithmetic sequence is:
S = n (a₁ + aₙ) / 2
where a₁ is the first term and aₙ is the last term.
252 = n (-16 + 72) / 2
n = 9
The nth term of an arithmetic sequence is:
aₙ = a₁ + d (n−1)
where d is the common difference.
72 = -16 + d (9−1)
d = 11
There are 9 terms, and the common difference is 11.
Answer:
500
Step-by-step explanation:
just multiply 50 by 15 and get 750
and then multiply 50 by 25 and get 1250
then do 1250-750 and get 500 cause thats the remaining area
Sale price = overall price for something
EX:
Shoes: $75.24
Tax (florida) 7%
7 turns to .07
.07 * 75.24 = 5.2668
round to nearest tenth
5.30
add this amount to total amount
75.24 + 5.30 = 80.54
And der u go
