This is because the original probability of getting a green marble is 1/3. There are 7 green marbles out of 21 which simplifies to that ratio. 

The second probability is 3/10 since there will be 6 green marbles left out of 20 total marbles. This simplifies to that ratio. 

Now we multiply the two ratios together. 

1/3 * 3/10 = 3/30 or 1/10, which is equal to 10%

If a 30-foot silo casts a 20-foot shadow, what is the approximate measure from the tip of the shadow to the top of the silo?
KATRIN_1 [288]

9514 1404 393

Answer:

  (d)  36 feet

Step-by-step explanation:

Use your sense of geometry.

The hypotenuse of a right triangle will never be less than the longest side, and will never be greater than 1.5 times the longest side*.

That means the only reasonable answer choices will be between 30 and 45 feet. There is only one such choice.

The measure is about 36 feet.

__

If you like, you can find a more exact value using the Pythagorean theorem. The distance d of interest is ...

  d^2 = 20^2 +30^2 = 1300

  d = √1300 = 10√13 ≈ 36.0555 ≈ 36 . . . feet

_____

* The longest hypotenuse will be √2 ≈ 1.4142 times the longest right triangle leg when the two legs are equal length.

otez555 [7]

So since he eats a pound of food when he weighs 3 ounces he eats about 5 and 1/3 times more than his own size. That means if we ate like shrews and we weighed 80 pounds we would eat about 426 pounds of food.
