Answer:
Step-by-step explanation:
Let he speed of the boat on the lake is x.
<u>Considering the speed of the current it will take him:</u>
- 22.5/(x + 6) + 22.5/(x - 6) = 9
- 2.5 / (x + 6) + 2.5 / (x - 6) = 1
- 2.5(x - 6 + x + 6) = (x + 6)(x - 6)
- 2.5*2x = x² - 36
- x² - 5x - 36 = 0
- x = (5 ± √(5² + 4*36))/2 = (5 ± 13) / 2
- x = (5 + 13)/2 = 9 mph (negative root is discarded as the speed should be positive)
Well you know that this stadium holds 50,000 people, you also know that it has 250 different seating sections. so you take 50,000 and divide that by 250 and your answer is 200. So there are 200 seats in each section. :)

Answer: 125.6 ml
Step-by-step explanation:
V = (3.14) (2^2) (10)
V = (3.14) (4)(10)
V= 125.6 cm^3
1 cubic centimeter = 1 milliliter
