35 students would not know any of the three languages, because if 30 know French, 19 knew German, and 16 knew Russian, that must mean that 65 students know at least one of the three languages. So you subtract 65 from 100 and end up with 35
Assuming that the x is not part of the ^-1 the range would be
[0,π/2) U (π/2,<span>π]</span>
Answer:
D
Step-by-step explanation:
We require to calculate the volume (V) of the cone and sphere.
The volume of a cone is calculated as
V =
πr²h ( r is the radius and h the height )
Here diameter = 5, hence r = 5 ÷ 2 = 2.5, thus
V =
π × 2.5² × 8 ≈ 52.36 cm³
The volume of a sphere is calculated as
V =
πr³ ( r is the radius )
Here diameter = 5, hence r = 5 ÷ 2 = 2.5, thus
V=
π × 2.5³ ≈ 65.45 cm³
Since volume of the sphere is greater than the volume of the cone
Thus when the ice cream melts it will overflow → D
You move all the varibles to one side and then divide it by the number it has remember if you do it for one side you do it to the other
I believe it is 3 non-collinear points.
