A Little League baseball stadium last row consists of 793 fans. The 11th row has 553 fans, the 12th row has 601 fans, the 13th row has 649 fans, and so on. How many rows are there?

I am pretty sure it is 16 rows.

Step-by-step explanation:

I subtracted 601 by 553, and got 48. I did the same with 649 and 601 and got 48. You would then add 48 to 649 and keep going until you get to 793. Then you would count how many times you added. The times you added plus 13, should get you 16. You should have added 3 times in all

b=8

Step-by-step explanation:

This is a right triangle, as we can see from the box in the corner.

We can use Pythagorean theorem to find the unknown side

a^2 +b^2 = c^2

where a and b are the legs and c is the hypotenuse

15^2 +b^2 = 17^2

225 + b^2 =289

Subtract 225 from each side

225-225 + b^2 = 289-225

b^2 =64

Take the square root of each side

sqrt(b^2) = sqrt(64)

b = 8
