BY using a BAC calculator, it was found that the BAC would be 0.0172. <span>The basic formula for estimating a person's blood-alcohol content or BAC comes from The National Highway Traffic Safety Administration. Hope this answers the question. Have a nice day.</span>
There are 14 tables with 8 chairs and 26 tables with 6 chairs in the cafe.
Step-by-step explanation:
Given,
Total tables at the cafeteria = 40
Table with 8 chairs = 35% = 
Tables with 6 chairs = 65% = 
Number of tables with 8 chairs = 0.35*Total tables
Number of tables with 8 chairs = 0.35*40 = 14 tables
Number of tables with 6 chairs = 0.65*40 = 26 tables
Therefore,
There are 14 tables with 8 chairs and 26 tables with 6 chairs in the cafe.

A simple exponential function to graph is y=2x . Notice that the graph has the x -axis as an asymptote on the left, and increases very fast on the right. Changing the base changes the shape of the graph. Replacing x with −x reflects the graph across the y -axis; replacing y with −y reflects it across the x -axis
Assume P(xp,yp), A(xa,ya), etc.
We know that rotation rule of 90<span>° clockwise about the origin is
R_-90(x,y) -> (y,-x)
For example, rotating A about the origin 90</span><span>° clockwise is
(xa,ya) -> (ya, -xa)
or for a point at H(5,2), after rotation, H'(2,-5), etc.
To rotate about P, we need to translate the point to the origin, rotate, then translate back. The rule for translation is
T_(dx,dy) (x,y) -> (x+dx, y+dy)
So with the translation set at the coordinates of P, and combining the rotation with the translations, the complete rule is:
T_(xp,yp) R_(-90) T_(-xp,-yp) (x,y)
-> </span>T_(xp,yp) R_(-90) (x-xp, y-yp)
-> T_(xp,yp) (y-yp, -(x-xp))
-> (y-yp+xp, -x+xp+yp)
Example: rotate point A(7,3) about point P(4,2)
=> x=7, y=3, xp=4, yp=2
=> A'(3-2+4, -7+4+2) => A'(5,-1)
