Is Part A correct? And can someone please help me with part B? (Highlighted)
Masja [62]
Part A. Your model is as good as any. It is hard to tell if the label needs to include the descriptor (length = 12 ft, for example). Certainly your model is sufficient for Part B.

Part B. The total area is the sum of the areas of each of the 6 faces of the box. Opposite faces are the same area, so you have
  A = 2(LW +WD +LD) = 2(LW +D(L +W))
Subsituting the given dimensions, you get
  A = 2((12 ft)(6 ft) +(3 ft)(12 ft +6 ft))
  A = 2(72 ft² +(3 ft)(18 ft))
  A = 2(72 ft² +54 ft²) = 252 ft²

The least amount of paper required to cover the box is 252 ft².

A dragonfly flies 7/8 of a mile in 3/10 of an hour. At this rate, how far can the dragonfly fly in 1 hour?
Rainbow [258]

Answer:The dragon fly can fly 35/12 miles

Step-by-step explanation:

Speed   =distance / time

If the distance A dragonfly flies 7/8 of a mile

And

Time  =3/10 of an hour.  

Speed =7/ 8 ÷3/10 =7/ 8 x 10/3 =70/24  reducing to lowest term becomes 35/12 miles / hour

Now when the dragon fly flies in 1 hour, its distance covered becomes

Speed   =distance / time

35/12 miles / hour=distance / 1

distance =35/12 miles
