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.

Use the number line below, where RS=5y+5, ST=2y+5, and RT=52. a. What is the value of y? b. Find RS and ST.

Alchen [17]

Answer:

y = 6, RS = 35 and ST = 17

Step-by-step explanation:

Given that,

RS = 5y+5

ST = 2y+5

RT = 52

If we consider a number line,

RT = RS + ST

52 = 5y+5 + 2y+5

52 = 7y + 10

7y = 52-10

7y = 42

y = 6

RS = 5y+5

= 5(6)+5

= 35

ST = 2y+5

= 2(6) +5

= 17

Hence, this is the required solution.
