Answer: a=2.72
Explanation:
Move all the terms containing a to the left side of the equation
-0.5a+4.96=3.6
Subtract 4.96 from right side
-0.5a=3.6-4.96
Would be
-0.5a=-1.36
Divide each term by -0.5 and simplify
a= 2.72
First, we would turn the number into a mixed, but unsimplified fraction of 12 and (28/100). Then, we would have to simplify the fraction into 7/25, at which point we can put the 12 with it and get an answer of 12 (7/25).
Hope this helps!
Given that most buildings average 12' per floor this building is likely to have approximately 62 floor
The parkers will pay A. $708.75
21 feet by 27 feet is 7 yards by 9 yards (3 feet per yard)
the area of the room is 7 yards * 9 yards = 63 square yards
if the carpet is $11.25 per square yard, multiply that number by the area
11.25 * 63 = 708.75
Well let's see.
If the figure is split up into 10 pieces, then
each piece is 1/10 of the whole figure.
If 2 of the pieces are shaded, then
2/10 of the whole figure is shaded.
How many pieces are left ?
There were 10 pieces all together, and
2 of them are shaded. Hmmm. I think
there are probably (10 - 2) = 8 of them left
that are not shaded.
8 pieces makes 8/10 of the whole figure.
