A softball fits snuggly inside a cubical box that is 4 inches on each side. What is the volume of the softball that fits snuggly

Natali5045456 [20]

Answer:

33.5 cubic inches.

Step-by-step explanation:

If the softball fits perfectly inside the cubical box, the softball is a sphere with diameter of 4 inches (radius os 2 inches).

The volume of a sphere is given by:

$V= \frac{4}{3}\pi r^3$

For r = 2 inches:

$V= \frac{4}{3}*3.14* 2^3\\V=33.5\ in^3$

The volume of the softball is 33.5 cubic inches.

Solve the following equation algebraically 4x^2 = 100

Licemer1 [7]

Answer:

x = ±5

Step-by-step explanation:

4x^2 = 100

Divide each side by 4

4/4x^2 = 100/4

x^2 = 25

Take the square root of each side

sqrt(x^2) = ±sqrt(25)

x = ±5

The drawing shown contains the intersection of two lines.

Phantasy [73]

Answer:

$\Huge \boxed{x=5}$

$\Huge \boxed{121\°}$

Step-by-step explanation:

∠1 and ∠2 are vertical angles.

∠1 = ∠2

Part A:

Create an equation and solve for x.

20x + 21 = 30x - 29

Add 29 and -20x on both sides.

20x + 21 + 29 - 20x = 30x - 29 + 29 - 20x

Simplify the equation.

50 = 10x

Divide both sides by 10.

$\frac{50}{10}$ = $\frac{10x}{10}$

Simplify the equation.

5 = x

Switch sides.

x = 5

Part B:

Let x = 5

20(5) + 21

Distribute.

100 + 21

Add.

= 121

Since both angles are vertical angles, they are equal.

∠1 = 121°

∠2 = 121°
