Answer:
3?
Step-by-step explanation:
im not 100% sure
First we have to know the formula of the volume f each of the solids,
<span>V of sphere = 4/3 pi r^3
</span><span>Volume of Cylinder = pi r^2(2r)=2pi r^3
</span><span>Volume of cone = 1/3 pi r^2(r)=1/3 pi r^3
</span>
The surest and easiest way we can answer this is actually assigning values. We first assign values to r hence we would get the volume of the sphere and rest of the solids (cylinder and cone). You then compare your answers to that of the sphere, and you should get your answer.
Answer:
It is proved that
.
Step-by-step explanation:
We already have the identity of x as
.......... (1) .
So, from equation (1) we can write that

⇒ 
⇒ 
⇒
Hence, it is proved that

Answer: false
Step-by-step explanation:
The exponents would have to have a different sign from each other (positive or negative), not the integer.
Answer:
the number is 10
Step-by-step explanation:
3x + 10 = 6x-20
20+10=6x-3x
30=3x
x=10
