Quotients can sometimes be irrational so it is necessary to estimate them, products on the other hand are only rational, provided they aren't multiplied by an irrational, so it is not necessary to estimate
$23.58 divided by 12 = $1.965
Each roll is about $1.97 (if you round up)
The answer is 78. This is because you change 8 2/3 into a improper fraction which is 26/3. Then do 26/3×9/1. You should cross cancel so cancel out 3 and change it into 1 and change 9 into 3. So now your problem is 26×3=78.

Answer:
The z-score of a teenage with waist size 33 inch is 2
Step-by-step explanation:
Mathematically, the z-score can be calculated using the formula;
z-score = (x- mean)/SD
where mean = 29 inches , SD = 2 inches and x = 33 inch
Plugging these values, we have
z-score = (33-29)/2 = 4/2 = 2
