The sides of a square aretwo to the power of four ninths inches long. What is the area of the square?

sergeinik [125]

Since the <span>sides of a square aretwo to the power of four ninths inches long.
</span>
Therefore, it can be written as :

The side of the square = $2^{ \frac{4}{9} }$

Now, area of square = (side)*(side) = $side^{2}$

Area, A = $(2^{ \frac{4}{9} } )^{2}$

or A = $(2^{ \frac{4}{9} } ) * (2^{ \frac{4}{9} } ) = (2)^{ \frac{4}{9} +\frac{4}{9} } = (2)^{ \frac{8}{9}$

Theresa has $12 in nickels amd quarters if she has the same number of each kind of coin how many nickels and quarters does she h

Bogdan [553]

n=# of nickels

q=# of quarters

$12 is 1200 cents

5n+25q=1200

n=q

substitute q for n or n for q

5q+25q=1200

30q=1200

q=1200/30

q=40 quarters and therefore n=40 nickels

40 quarters is $10 and 40 nickels is $2, therefore you have $12

Hope this helps.
