Volume of the bead = Volume of the sphere - volume of the cylindrical hole = 242.95 mm³.

<h3>What is the Volume of a Sphere and a Cylinder?</h3>
  • Volume of a sphere = 4/3πr³
  • Volume of a cylinder = πr²h

Volume of the bead = Volume of the sphere - volume of the cylindrical hole

= 4/3π(4³) - π(1²)(8)

= 268.08 - 25.13

Volume of the bead = 242.95 mm³

2(9x-5)=6(3x+4)<br> Solve for x <br> Algebra
andreyandreev [35.5K]

Answer:

No solution

Step-by-step explanation:

2(9x-5)=6(3x+4)

Step 1 is to do distributive property.

so you will get this:

18x-10=18+24

step 2 is combining like terms.

so you will subtract 24x from both sides.

(this:) 18x-10=18x+24

(into this:) -10=24

I got this because when you subtract 18 from 18 you will get zero (0).

So your answer will be:

No solution

Which of the following is a measurement conversion that you may need to make when comparing energy and mass in nuclear reactions
DiKsa [7]
The correct option is C. In Nuclear reactions, two nuclear particles collide to produce products that are different from the reactants. During nuclear reaction, a lot of processes take place. In nuclear reactions, the total energy is conserved. Thus, the missing rest mass energy can be accounted for by using the Einstein's formular  to find mass - energy equivalence.

The width of a rectangle is 4x-1 feet and the lenth is 2x+3 feet
KengaRu [80]
If you are asking for the area of the rectangle...

Let L = Length

Let W = Width

Let A = Area of rectangle

A = LW

A = ( 2x + 3 ) ( 4x - 1 )

A = 8x^2 - 2x + 12x - 3

A = 8x^2 + 10x - 3

If you are asking for the perimeter of the rectangle...

Let L = Length

Let W = Width

Let P = Perimeter of rectangle

P = 2L + 2W

P = 2 ( 2x + 3 ) + 2 ( 4x - 1 )

P = 4x + 6 + 8x - 2

Expanded form -

P = 12x + 4

Factorised form -

P = 4 ( 3x + 1 )

Hope this helps! :)
