Answer:
The dimensions of the box are 12 cm , 12 cm , 12 cm
Step-by-step explanation:
Let x , y and z be the dimensions of box
Volume of box =xyz=1728

Surface area of box = 
Let 
To get minimal surface area
and 


----1


Using 1

x=0 and 
Side can never be 0
So,
x=12

y=12

z=12
The dimensions of the box are 12 cm , 12 cm , 12 cm

Also quick note 2269.95 is how much is made in a month! :)
Answer:
The correct options are 1, 3 and 4.
Step-by-step explanation:
We need to find the expressions whose simplified form is a rational number.
Rational number: If a number is defined in the form of p/q where p and q are integers and q≠0, then it is called a rational number.
For example: 0,2, 4.3 etc.
Irrational number: If a number can not defined in the form of p/q, where p and q are integers and q≠0, then it is called an irrational number.
First expression is

12 is a rational number.
Second expression is

is an irrational number.
Third expression is

21 is a rational number.
Fourth expression is

5 is a rational number.
Therefore, the correct options are 1, 3 and 4.
This is a two step problem. First, you need to find the difference (or increase) in the rent using subtraction.
616-560 = $56 increase
Now we need to figure what percent 56 is to the original amount (560)
We voice it like this:
56 is to 560 as x is to 100.
The equation looks like this:
56/560 - x/100
Cross multiply to cancel out the denominators.
56 x 100 = 560 x
5600 = 560 x
x = 10 percent.
Check it!
What is 10 percent of 560?
560 x .1 = $56
Was that your increase? ... yes.
