Answer:

n = 12

Step-by-step explanation:

Rewrite it as \frac{(n+3)}{5} = 3

Multiply both sides by 5

(n+3) = 15

You can drop the parenthesis now.

n + 3 = 15

n = 12

Find the volume and round to the nearest tenth as needed
monitta

Answer: 1962.4 cubic mm

Step-by-step explanation:

The volume of the larger cone is V=\frac{1}{3}(\pi)(10^{2})(20)=\frac{2000\pi}{3}

The volume of the smaller cone is V=\frac{1}{3}(\pi)(3^{2})(14)=42\pi.

So, the volume is \frac{2000\pi}{3}-42\pi \approx \boxed{1962.4}

What is the solution of the system of equations?
umka21 [38]

No solution of the system of equations y = -2x + 5 and -5y = 10x + 20 ⇒ 2nd answer

Step-by-step explanation:

Let us revise the types of solutions of a system of linear equations

  • One solution
  • No solution when the coefficients of x and y in the two equations are equal and the numerical terms are different
  • Infinitely many solutions when the coefficients of x , y and the numerical terms are equal in the two equations

∵ y = -2x + 5

- Add 2x to both sides

∴ 2x + y = 5 ⇒ (1)

∵ -5y = 10x + 20

- Subtract 10x from both sides

∴ -10x - 5y = 20

- Divide both sides by -5

∴ 2x + y = -4 ⇒ (2)

∵ The coefficient of x in equation (1) is 2

∵ The coefficient of x in equation (2) is 2

∴ The coefficients of x in the two equations are equal

∵ The coefficient of y in equation (1) is 1

∵ The coefficient of y in equation (2) is 1

∴ The coefficients of y in the two equations are equal

∵ The numerical term in equation (1) is 5

∵ The numerical term in equation (2) is -4

∴ The numerical terms are different

From the 2nd rule above

∴ No solution of the system of equations

No solution of the system of equations y = -2x + 5 and -5y = 10x + 20
