What is the solution of 3x + y = 9 and 3x − 5y = 15?

erma4kov [3.2K]

Answer:

Multiply the first equation by five to yield, 15x + 5y = 45. Add this equation to the second equation from the given,

15x + 5y = 45

+ 3x - 5y = 15

The answer would be 18x = 60. The value of x is 10/3. Therefore, the answer to this item is letter A.

The formula for the volume of a cone is V = jarh, where V is the volume, r is the radius, and h Is the heightWhat is the volume

olga nikolaevna [1]

Given:

The radius, r=4x

The height,

$h=21xy^2$

To find the volume of the cone:

The volume of the cone formula is,

$V=\frac{1}{3}\pi r^2h$

Substitute the values of r and h in the above formula we get,

$\begin{gathered} V=\frac{1}{3}\pi\times(4x)^2\times21xy^2 \\ =\frac{1}{3}\pi\times16x^2\times21xy^2 \\ =\pi\times16x^2\times7xy^2 \\ =112\pi x^3y^2 \end{gathered}$

Hence, the volume of the cone is

$V=112\pi x^3y^2$

Thus, the correct option is option D.
