Construction In the remodel of a two-story home, a stairwell opening, S, is determined by the formula
where Uru is the unit run, Uri is the unit rise, H is the head clearance, and T is the floor thickness. The quantity in brackets must be rounded up to the next whole number before multiplying by Uru. Find the stairwell opening if Uru = 9 in.,

Unfortunately, sometimes inaccurate information can get entered because the statementhas a “True” truth value even if there is incorrect information in part of the statement. For eachstatement below, determine if the entry will get past the automated system or will be labeled with a“False” truth value and end up being returned to the sender.Notes:1.
