cL is the SI unit "centiliters." The prefix "centi-" mean 1/100 or 0.01 units. Then 18 cL = 18 × 0.01 L = 0.18 L.
mL is the SI unit "milliliters." The prefix "milli-" means 1/1000 or 0.001 units. Then 9 mL = 9 × 0.001 L = 0.009 L.
First we convert feet into meters, since 1 feet is 0.3048 m: 275 feet * 0.3048 = 83.82m.
Then we do: 83.82m / 3.23s = <span>25.9504644 m/s.
Then we convert that into miles per hour by </span>2.23694, so we do:
25.9504644 * 2.23694 = <span>58.0496318.
Then we round it to 58 mph.
So the answer is: The cheetah was running at 58 mph.

Answer:
∠B = 60°
Step-by-step explanation:
They are supplementary angles, which means they add up to 180°.
∠B + ∠A = 180
? + 120 = 180
? = 180 - 120
? = 60°
