Answer:

More clarification

Step-by-step explanation:

2 of a white ball =2/30 =1/15;

This is the probability of picking a black ball.

Let the number of black ball be X

x/(x +20)= 1/15[ probability of picking black ball ]

15x = x + 20 ; by cross multiplication

14x=20; x = 20/ 14 =1.42 = 1 [ approximately]

But to satisfy the premise given above; we have to approximate the no of balls to 2

Y = 6x
Illusion [34]
<span> Not to worry, Anarkee, it's easy. They just dress it up in tech-speak. What it means is "For what pair of numbers in the list is the statement "Y = 6x" true, if the first number is x and the second is y".

You will notice that in every pair, one number is 6 times the other, but if the numbers are arranged as ORDERED pairs, the convention is that x comes before y. therefore only B, C and E satisfy the equation.

Simple but sneaky, huh? </span>

Once again super confused
Katena32 [7]
Well, you see the yellow colored "face" Think of it as area. So we got a smaller square next to it right...just ignore it and look at the yellow square. So, how do you find the area? Length times width right? So, since this cube has 4 inches all over it, what do you think you have to do if a square has equal sides/measurements. You multiply 4*4, which is 16! NOTE: It is NOT asking for volume! Hope this helps!
