Answer:
27
Step-by-step explanation:
Let the radius of the smaller sphere is x.
Then the radius of the larger sphere is 3x.
The volume of a sphere is given by
Hence, the volume of the smaller sphere is
And the volume of the larger sphere is
Divide both volumes, we get
Hence, the volume of the smaller sphere is 27 times smaller than the volume of the larger sphere.
Answer:
(x-5)(x+1)
Step-by-step explanation:
Since the highest power of x is 2, u can assume the equation to be (x +/- A) (x +/- B), whereby A and B are unknowns.
Since the coefficient of X^2 is 1, and the number in the equation is - 5, the only possible values for A and B to get - 5 is either - 5 and 1 or 1 and - 5.
Since coefficient of x is - 4 and number in equation is - 5, imagine inserting those numbers in the equation and cross multiplying back. You would realise that the answer should be as listed above.
