I'm going to try this one more time... Which of these characteristics of a star make it most likely to become a black hole? Select the TWO correct answers.

A. Its mass is equal to that of the sun.

B. It has an abundant supply of hydrogen.

C. Its mass is greater than 20 times the mass of the sun.

D. It is dying.

Answer and Step-by-step explanation:

C and D  is the answer.

It needs a lot of mass so that it can collapse on itself to form a black hole, and when it dies, it also collapses on itself, forming a black hole.

A is incorrect because the mass of our sun hasn't made it to collapse, and it still has some billions of years before the mass increases.

B is incorrect because the hydrogen needs to be depleted in order for the sun/star to start the nuclear process.

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
