Number of seats = 42
Seats per row x row = 1302
s x r = 1302
rows + 11 = seats per row
r + 11 = s
s x r = 1302
(r + 11) x r = 1302
r^2 + 11r = 1302
r^2 + 11r - 1302 = 0
(r + 42) x (r - 31) = 0
r = -43 or 31
Cannot have negative rows so the number of rows is 31, and the number of seats per row is 31 + 11 = 42
Check: 31 x 42 = 1302 :)
h = 19 Meters

Step-by-step explanation:
27^1/3 = cuberoot(27) = 3
Answer:
$4,320
Step-by-step explanation:
I equals PRT. I is the interest. P is the principal, amount borrowed. R is the rate, percent. T is the amount of time in years. Principal in this is 16,000. Rate is 9%, or 0.09. Time is 3 years. So 16,000 times 0.09 times 3 equals 4,320. That is the interest.
Answer:
y≥ 23
Step-by-step explanation:
y/3 - 7 ≥ 2/3
Add 7 to each side
y/3 - 7+7 ≥ 2/3+7
y/3 ≥ 2/3+21/3
y/3 ≥ 23/3
Multiply each side by 3
y/3 *3 ≥ 23/3*3
y≥ 23
