Answer:
3√11
Step-by-step explanation:
You use the Pythagorean Therom, 18^2-15^2 give you 99. You find the square root of 99, you break it down into 9 and 11. Take the square root of 9, which is three, and you cant seperate 11. So thats how you get 3√11

Answer:
(- 5, 5 )
Step-by-step explanation:
5x + 7y = 10 → (1)
- 9x + y = 50 ( add 9x to both sides )
y = 9x + 50 → (2)
substitute y = 9x + 50 into (1)
5x + 7(9x + 50) = 10
5x + 63x + 350 = 10 ( subtract 350 from both sides )
68x = - 340 ( divide both sides by 68 )
x = - 5
substitute x = - 5 into (2)
y = 9(- 5) + 50 = - 45 + 50 = 5
solution is (- 5, 5 )
The ratio of the volume of the cylindrical tank to its surface area will be r / 2.
<h3>What is a cylinder?</h3>
A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.
Let r be the radius and h be the height of the cylinder.
Then the volume of the cylinder will be
V = π r²h cubic units
Then the surface area of the cylinder will be
SA = 2πrh square units
Then the ratio of the volume of the cylindrical tank to its surface area will be
V / SA = π r²h / 2πrh
V / SA = r / 2
The ratio of the volume of the cylindrical tank to its surface area will be r / 2.

Answer:
Y-intercept is (0, 100) and the X-intercept is (-250, 0)
Step-by-step explanation:
For the y-intercept the line from the origin does not move left or right and stays at 0 but it goes up by 100.
For the x-intercept the line does not go up and down but it goes to the left -250.
