Answer:
81
Step-by-step explanation:
27 total of pupils.
girls 1×27=27
boys 2×27=54
total 54+27=81
N-2= 1/16
⇒ n= 1/16+ 2 (inverse operation)
⇒ n= 2+ 1/16
⇒ n= 2 1/16
Final answer: n= 2 1/16.

Answer:
A
Step-by-step explanation:
Because the area of a square is the length of one side multiplied by itself, the area of this square would be 39.0625.
But, this is not the answer that is asked for. The problem gives you 3 significant digits, so we need to round 39.0625 to 3 significant digits. This would be 39.1 square feet.
