Answer:

1948 cm

Step-by-step explanation:

First, calculate the circumference of the wheel with tire.  Since C = πd, the circumference in this particular case is C = π(62 cm), or approx. 194.8 cm.

Each time the wheel turns, the bike moves forward 194.8 cm.

If the wheel turns 10 times, the bike moves forward 1948 cm.

Let the graph of f(x) represent the cost in thousands of dollars to feed the zoo animals daily, where x is the number of animals
pickupchik [31]

Answer:

<u>There are 200 animals, and the cost is $8,000 daily</u>

Step-by-step explanation:

y=f(x) represents the cost in thousands

x is the number of animals measured in hundreds

so the point (2,8) means

x = 2

y = f(2) = 8

so it means  for 2*100=200 animals, the cost is 8*1000=8 000

The correct answer is then

There are 200 animals, and the cost is $8,000 daily

hope this helps
