If we are to choose any number from 100 to 500, you may take any other number but for the purpose of showing how things are done here, let me choose 100 gallons. Similarly, we choose 2 gallons to be drain out each day.
The equation that would best represent the relationship between the given parameters is,
y = 100 - 2x
where y is the volume of water after x days.
Answer:
1.6 ft
Step-by-step explanation:
Each time the wheel does a complete turn, the bike moves forward a distance equal to the wheel's circumference. Since the bike moves 200 ft after 40 rotations, the length of the wheel's circumference is:
C = 200 ft / 40
C = 5 ft
Circumference is π times the diameter. So the diameter of the wheel is:
C = πd
5 ft = πd
d = 1.6 ft
