Sergio wants to glue a ribbon around the top of a cube box with a volume of V. Which expression gives the length of the ribbon?

Length of ribbon = 4 ×  ∛(V)

Step-by-step explanation:

The question is incomplete without the options of the expression to choose from.

Find attached the diagram used in solving the question.

Volume of a cube = side × side × side

Let side = s

Volume of a cube = side³ = s³

Volume of cube box = V

V = s³

s = ∛(V)

The shape of the top of a cube box is a square.

Length of the ribbon to be used to glue round the top of a cube box = Perimeter of a square

Perimeter of a square = length + length + length + length  = 4× length

Length = side

Perimeter of a square = 4×s

Perimeter of a square = 4 ×  ∛(V)

Length of ribbon = 4 ×  ∛(V)

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
