Mary will be 24 years old when she will be twice as old as her brother.

Here's how this has been calculated:

If Mary is 16 years old and 4 times older than her brother, her brother's age

= 16/4

=4

Mary’s brother is therefore 4 years old.

Now let’s calculate the difference between Mary and her brother’s age through subtraction:

 Mary’s age- her brother’s age= 16-4

                                                 =12

 

Therefore, Mary is 12 years older than her brother

 

So, for Mary to be twice as old as her brother, the formula will be= 12*2

                                                                                                         =24

Therefore, Mary will be 24 years old when she will be twice as old as her brother.

Over the long term, the most significant threat to U.S. interests in the Indian Ocean region is ______________.
Mila [183]

Answer:

India

Explanation:

India is the most significant threat to U.S. interests in the Indian Ocean because it is the only country of the region that has the potential of becoming a superpower.

This is because India is the second-most populated country in the world (after China) with a population of over 1,300 million people. Besides, because India has a higher population growth than China, it will become the most populated country in the near future.

The country is also developing fast after undergoing liberal economic reforms in the last decades.

The increased wealth and development will allow Indian governments to invest more in the military, and perhaps, become a real adversary for the U.S. in the long-term.
