Answer:
Option 4. Perimeter = 30 units
Step-by-step explanation:
Since the volume of a pentagonal prism is 840 cubic units.
Perpendicular distance between the bases = 14 units
We know volume of a pentagonal prism = Area of base × distance between the bases
840 = Area × 14
Area = 840/14 = 60 square units
Now area of a pentagon
Therefore perimeter of the pentagon = 5×a = 5×5.91 = 29.54 ≈ 30 units
Answer:
Step-by-step explanation:
A car can travel for a distance of 350 miles in = 20 gallons
The car can travel for a distance of 1 mile in = (20/350) gallons
= 2/35 gallons
Then
The same car can travel for a distance of 875 miles in = (2/35) * 875 gallons
= 1750/35 gallons
= 50 gallons
So it can be seen that 50 gallons of gasoline is required to travel for a distance of 875 miles. I hope the procedure is clear enough for you to understand.
Your answer should be 3.75
