While Preparing For A Morning Conference, Principal Corsetti Is Laying Out 8 Dozen Bagels On Square Plates. Each Plate Can Hold
USPshnik [31]
We have 8 dozen bagels, or 8*12=96 bagels.  Each plate can hold 14 bagels, so we have enough bagels to fill 96/14=about 6.86 plates.  However, we cannot have a fraction of a plate, so we round up to have a total of seven plates.  To fill all seven plates fully, 7*14=98 bagels would be needed, which is two more than we have.

To summarize, Mr. Corsetti has seven plates of bagels, and would need two more bagels to fill the last one up.

Which of the following is equivalent to<br> (16 3/2)^1/2 ?<br><br> O 6<br> O 8 <br> O 12<br> O 64
Galina-37 [17]

Step-by-step explanation:

=  { ({16}^{ \frac{3}{2} } )}^{ \frac{1}{2} }

=  { ({( {2}^{4}) }^{ \frac{3}{2} } )}^{ \frac{1}{2} }

=  {2}^{4 \times  \frac{3}{2} \times  \frac{1}{2}  }

=  {2}^{ \frac{12}{4} }

=  {2}^{3}

= 2 \times 2 \times 2

= 8

The answer is B.
