Which equations are true? Choose all answers that apply: Choose all answers that apply: (Choice A) A -x +0+(- x) = 0−x+0+(−x)=0m

lora16 [44]

Answer:

(B)-x-(-x) =0

Step-by-step explanation:

Option A

Our equation is: -x +0+(- x) = 0

Left Hand Side:

-x +0+(- x) = -x-x=-2x

$($Left Hand Side) $-2x\neq 0$ (Right Hand Side)$

Option B

Our equation is: -x-(-x) =0

Left Hand Side:

-x-(-x) =-x+x=0

$($Left Hand Side) 0 = 0 (Right Hand Side)$

Therefore, the equation in Option B is true.

I need help find the volume of the composite solid use 3.14 for pi

Evgen [1.6K]

Answer:

$222.312\:\mathrm{in^3}$

Step-by-step explanation:

The composite solid consists of a cylinder and a cone. Therefore, its total volume will be the sum of the volumes of the cylinder and cone:

Volume of the cone: $\frac{1}{3}\cdot 2^2\cdot 3.14\cdot 8.1 =33.912$

Volume of the cylinder: $2^2\cdot 3.14 \cdot 15=188.4$

Thus, the total volume of the solid is:

$33.912+188.4=\boxed{222.312\:\mathrm{in^3}}$
