The answer will be B.
First you need to find the probability of the red marbles which is 5/12 because there is 5 marbles and if you add they up there would be 12. Then you find the probability of the green marbles which is 2/12. After that you need to multiply them. 5/12 × 2/12. Your answer will be 10/144 but then you can simply by 2.
So your answer will be 5/72.
Hope this helped.
Answer:
no x = -8/13
Step-by-step explanation:
6x – (3x + 8) = 16x
Combine like terms
6x -3x -8 = 16
3x-8 = 16
Subtract 3x from each side
3x-8-3x = 16-3x
-8 = 13x
Divide by 13
-8/13 = 13x/13
-8/13 =x
Answer:
Step-by-step explanation:
area including track=area of 2 semi circles+area of rectangle
=2×1/2×π×46²+86×65
=2116 π+5590
area of grass=2×1/2×π×40²+80×65=1600π+5200
≈10226.55 m²
area of track=2116π+5590-1600π-5200
=516π+390
≈2011.06 m²

This isn't the answer but if you can take a pic of this and put it in this app called "Math-way" or "Photo-math" those help me
Answer:
Step-by-step explanation:
b/c these are similar triangle we can say this ratio of the two triangles is true
15/x = 31/(44+x)
now just use algebra to solve for x
15*(44+x) = 31x
660+15x = 31x
660=16x
41.25 =x
41.3 looks good
