No it is not. A perfect square is a number that, if you take the square root of, gives you a whole number.
A perfect square would be :  1, 4, 9, 16, 25, 36, 49 etc.

No, 50 is not a perfect square.  A perfect square is any number that can be divided by any number to get the quotient as the same number AND the quotient must be rational.  When you divide 50 so that the quotient equals the divisor, you will get an irrational number.  Therefore, 50 is not a perfect square.

Katarina [22]

Answer:

34091 dollars per person

Step-by-step explanation:

In order to answer the question, you have to divide the amount of debt by the amount of population to obtain the amount of dollars per person.

The debt was $10.5 trillion. A trillion is a thousand billion  (1000 multiplied by a billion which is 10^{9} in scientific notation)

1000=10^{3}

One trillion is (10^{3})(10^{9})=10^{12}

The debt is: $ 10.5 x 10^{12}

The population is scientific notation is: 308.0 x 10^{6}

Dividing the amount of debt by the amount of population:

\frac{(10.5)(10^{12})}{(308.0)(10^{6})}=\frac{(10.5)(10^{12-6})}{308.0}=\frac{(10.5)(10^{6})}{308.0}

Simplifying and expressing it in standard notation:

34090.9 dollars per person

Rounding to the nearest dollar:

34091 dollars per person.

A certain natural number is not divisible by 7. Can it be divisible by 14, explain why or why not
Elanso [62]
For a number to be divisible by 14 it needs to be both divisible by 7 and 2 which are factors of 14. Every time you have a number (x) to check if it is divisible by some larger number you find the factor of that larger number and check is the x divisible by both.

Answer: it cannot be divisible by 14.
