X = 10 opposite sides are equal to eachother
Answer: probability for 1st marble being green is 2/9 and 2nd marble being red is 1/4
Step-by-step explanation:
I hope this is correct. since there are 9 marbles and 2 of them are green, you do 2/9 which is 2/9 in its simplest form. And since you didn't put back the first marble there are 8 marbles left and 2 of them are red. You do 2/8 which in its simplest form is 1/4. I hope this helps

Answer:
V = 16
Step-by-step explanation:
Put the given value into your equation and solve for the variable.
p = 8/v
1/2 = 8/v
It should be no mystery that 1/2 = 8/16, but we can show v=16 algebraically by multiplying both sides of this equation by the product of denominators (2v).
2v/2 = 8(2v)/v
v = 16 . . . . . . simplify
Answer:
7. 49
8. 10.4
Step-by-step explanation:
7) our hypotenuse is 8, and the side opposite the base of ladder and ground angle is 6, therefore we can use Sin
sin = opposite/hypotenuse
sin(x) = 6/8 = 3/4
sin-1(3/4) = 49
8) using the theorem that alternate exterior angles are congruent
the angle opposite side x is 30
tan = opposite/adjacent
tan(30) = x/18
x = 18tan(30) = 6√(3) = 10.4
you can also use 30-60-90 special right triangles.
the side opposite 30 is x
side opposite 60 is x√(3)
and side opposite 90 is 2x
