13/13=1 you have to do 13/13 which is really 1
It needs more information for someone to answer sorry:/
Area of rectangle: b*h
12*5=60
10*5=50
(60*4)+(50*4)=440
The total surface area of the visible sides of the boxes would be 440 square inches.
Hope this helps!
Answer:
Any whole number is over one...so if the whole number was 5 it would be 
bkuz the line in between the numerator and denominator is a dividing sign and 5 divided by 1 is 5
So you put the whole number whatever it is over 1 then multiply that by the fraction
Example:
6 x 
is the same as saying 
x which equals 
because 6 times 3 equals 18 and 4 times 1 equals 4
Now you need to simplify or divide...
So, is the same as 
or 
bkuz 4 goes into 18 4 and a half times
Evaluating the given sequence, it is evident that the next number is twice the number prior to it. Thus, the given is a geometric sequence with first term (a1) equal to 1 and common ratio of 2. The geometric series may be calculated by the equation,
Sn = a1 x (1 - r^n) / (1 - r)
where Sn is the sum of n terms in this case, n = 11.
Substituting the known values,
<span> Sn = 1 x (1 - 2^11) / (1 - 2) = 2047
</span>
Thus, S11 is 2047.
