A. A 5in radius ball is in a

abruzzese [7]

Answer:

52.33%

Step-by-step explanation:

Since, all six sides of the box are touching the ball.

So, all the three dimensions of the box are equal.

Hence, it is a cubical box.

Side length of the box (l)

= diameter of the ball

= 2*radius of the ball

= 2*5

= 10 In.

$V_{ball} = \frac{4}{3} \pi r^3$

$V_{ball} = \frac{4}{3} \times 3.14(5)^3$

$V_{ball} = \frac{4}{3} \times 3.14\times 125$

$V_{ball} = \frac{1,570}{3}\: In^3$

$V_{box} =l^3$

$V_{box} =(10)^3$

$V_{box} =1000\: In^3$

Percentage of the space in the box occupied by the ball

$= \frac{V_{ball}}{V_{box} } \times 100$

$= \frac{\frac{1,570}{3}}{1000} \times 100$

$= \frac{1570}{3000} \times 100$

$= \frac{157}{3}$

$= 52.33\%$

To solve -3 = -19 + d/5, what steps would you use?

Phantasy [73]

Answer:

1)Add 19

2)Multiply by 5

Step-by-step explanation:

$-3=-19+\frac{d}{5}$

Adding 19 to both sides.

$-3+19=-19+19+\frac{d}{5}\\\\16=\frac{d}{5}$

Multiplying 5 to both sides.

$16\times5=\frac{d}{5}\times 5\\80=d\\\\$

∴ $d=80$
