Answer:
m =
Step-by-step explanation:
Given
c = 2m - 2c ( isolate 2m by adding 2c to both sides )
3c = 2m ( divide both sides by 2 )
= m
7² + 10² = c² where c = hypotenuse
49 + 100 = c²
149 = c²
c = √149 feet
Answer:
26 cm^3
Step-by-step explanation:
volume of cylinder = (pi)r^2h
volume of cone = (1/3)(pi)r^2h
Since (pi)r^2h = volume of cylinder, then you get
volume of cone = (1/3)(volume of cylinder) = (volume of cylinder)/3
The difference between the volume of a cylinder and the volume of a cone is that a cone with the same radius and height has 1/3 the volume of the cylinder.
If you know the volume of a cylinder, then the volume of a cone with the same radius and height is 1/3 the volume of the cylinder, or simply, divide the volume of the cylinder by 3.
volume of cylinder = 78 cm^3
volume of cone = (78 cm^3)/3 = 26 cm^3
Answer:
x = 4.
Step-by-step explanation:
2x + 4 = 5x – 8
Subtract 2x from both sides:
4 = 5x - 2x - 8
Add 8 to both sides:
4 + 8 = 3x
3x = 12
x = 4.
