The first row of a section in a stadium has 10 seats. The second row has 11 seats. The third row has 12 seats. This pattern continues and the section has 24 rows.How many seats are in this section?

Answers

Answer 1
Answer:

1st row = 10 seats

2nd row = 10 + 1 = 11 seats

3rd row = 10 + 2 = 12 seats

nth row = 10 + (n-1) seats


Find the number of seats in the 24th row:

24th row = 10 + (24 - 1) = 33 seats


Find total number of seats:

Total number of seats = (n)/(2) (a_1+a_(24)) = (24)/(2) (10+33)= 516

because it can be expressed as a fraction of two integers (12/1).

a cereal box is 8 1/2 inches long, 3 1/2 inches wide, and 12 inches high. what is the volume of the the box?

Answers

Length of the cereal box = 8 1/2 inches
                                        = 17/2 inches
Width of the cereal box = 3 1/2 inches
                                      = 7/2 inches
Height of the cereal box = 12 inches
Then
Volume of the cereal box = Length * Width * Height
                                        = (17/2) * (7/2) * 12 cubic inches
                                        = 17 * 7 * 12 cubic inches
                                        = 1428 cubic inches
I think its 357 squared. Just multiply all of it together. I'd check the formula for finding volume if you want a reliable answer
