Answer:
The theater has 32 rows
Step-by-step explanation:
The rule of the sum of n terms of an arithmetic sequence is S
= 
(a + l), where
- n is the number of the terms
∵ The number of seats per row follows an arithmetic sequence
∵ The first row has 26 seats
∴ a = 26
∵ The last row has 150 seats
∴ l = 150
∵ The theater seats are 2,816
∴ S = 2,816
→ Substitute these values in the rule of the sum above to find n
∵ 2,816 = (26 + 150)
∴ 2,816 = (176)
∴ 2,816 = 88n
→ Divide both sides by 88
∴ 32 = n
∵ n represents the number of the rows
∴ The theater has 32 rows
Answer:
Net worth is defined as:
Assets - Liabilities.
Assets are what you own.
Liabilities are what you have to pay.
So, home + truck + investments are assets.
Likewise, mortgage + student loans + credit cards are liabilities.
Doing the math, Susan's net worth is
Assets - Liabilities
$143,392.90 - $98,077.12 =
$45,315.78
Susan's net worth is $45,315.78
Good luck!

Answer:
Step-by-step explanation:
Since we are given the hypotenuse which is 18 since it slanted, and leans on the house. And we are given one of the legs which is 15 since it is vertical. We can use the pythagorean theorem to solve for this problem.
where a and b are the legs and c is the hypotenuse l.
Let plug it in
