To find how many seats in the 80th row, you need to figure out the pattern from the 8th row to the 20th row.
To do this, you can create a table showing possibilities from the 8th to the 20th.
I started with 32 at the 8th and added 2 each time. This was only 56 by the 20th.
Then I added 3, and this got me to 68 by the 20th row.
Then you can work backwards to find how many seats in the 1st row. I got 11.
From here you can create an equation that you could use to solve for the 80th row.
11 + 3(r - 1), where r is the number of rows.
Substitute in 80 for r.
11 + 3(80 - 1)
11 + 237
248 seats
There are 248 seats in the 80th row.
The circumcenter is the center of a triangle's circumcircle. It can be found as the intersection of the perpendicular bisectors.
The conditional statement is
if x < y:
result = x * 5
<h3>How to write the if/else statement as the conditional expression that performs the same option?</h3>
The statement is given as:
result = x < y ? x * 5
The above means that,
the variable result is assigned x * 5 if x < y
So, the conditional statement is
if x < y:
result = x * 5

Answer:29
Step-by-step explanation:
Since he has to give 50, and 12.25*p is the amount of money he has to spend (since it's 12.25 per pizza), we have 50-12.25=change
