The notation of a bar (vinculum, or overbar) over a whole number
doesn't seem to be very common. Here are some possibilities as to
what it could mean:
It is sometimes used as a grouping symbol, as in a fraction:
_____ __
3 + 1 x 5 = 20 so 67 = 67
I have also seen it used to refer to the average:
_ __
x = {1,2,6}, x = 3 so 67 = 67
(the average of one number is itself, of course).
I have also heard that it can be used to mean "1000 times whatever is
underneath", especially with Roman numerals - see the following Web

Answer:
b=3a/8
a=8b/3
Step-by-step explanation:
b/a=k ( k is the constant proportional)
3/8=9/24=15/40
b/a=3/8
b=3a/8
a=8b/3
I hope this is right answer
<u>Add</u> them all up, 3.2 + 1.75 + 1.9 = <u>6.85</u>
The total weight is <u>6.85</u> pounds.
Check the picture below.
so, to get the area of the triangles, we can simply run a perpendicular line from the top to the base, and end up with a right-triangle with a base of 22 and a hypotenuse of 34, let's find the altitude.
so then the surface area of the triangular prism is,

Answer:
A)
$13.79 per ticket
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential increase function:
A = P (1 + r) t
Where:
p = original price
r = increase rate (decimal form)
t= years
A = price after t years
Replacing with the values given:
A =7.50 (1+ [7/100]) ^9
A = $13.79 per ticket
