Answer:
Step-by-step explanation:
Since this is a system with two equations, we can easily use a graphing calculator to find the solution
The intersection between the graphs of the equations
y = 3x + 10
2y = 6x – 4 (if we divide by two)
y = 3x - 2
However, we can see that the graphs have the same slope m = 3
Since both equations are not equal, there is no solution for this system
Please see attached graph. The lines are parallel and they never touch each other.
Answer:
226.19 
Step-by-step explanation:
Vol. of cone = Bh/3 where B is the area of the base(circle) and h is the height of the cone.
r = 3 h = 3
V =
= 9π
Vol. of the cylinder = Bh where B is the base(circle) and h is the height of the cylinder.
r = 3 h = 10 - 3 = 7
V =
= 63π
Total volume = 9π + 63π = 72π = 72(3.1416....) = 226.19
I don’t really get what exactly you need help with, maybe put a picture?
Answer: 90
Step-by-step explanation:
216/36 is 6. Then, on average, it's 15 weeks. So 6x15 is 90. There's your answer. I think.
