582.74 square inches of glass is required to construct the tank
Step-by-step explanation:
Base dimensions= 22 x 12 inches
Volume of the fish tank = 3960 cubic inches
Volume = l x w x h
3960 = 22 x 12 x h
h = 3960 /(22 x 12)
h = 3960/462
h = 8.57 inches
The glass used = lateral surface area of the rectangular prism
= 2(lh + wl)
= 2(188.57 + 102.8)
= 2(291.37)
= 582.74 square inches

Answer:
a) Ans: 8.5 miles per hour
b) Ans: 46.75 miles
Step-by-step explanation:
a) Speed = Distance/Time
8.5/1h = 8.5 miles per hour
b) Distance = Speed x Time
8.5 miles per hour x 5.5h = 46.75 miles
Z = -2/3a
divide by -2/3 on both sides
a = z divided by -2/3
a = -3/2z
