Answer:
2/13
Step-by-step explanation:
In a deck of 52 cards, there are 2 sets of red cards. Diamonds and Hearts. In each set of red cards, there are 4 fives. If there are 2 sets, that means that there are 8 red fives in the deck of 52 cards. This means that the probability is 8/52 which is simplified into 2/13.
Answer:
B) 43.82 feet/sec
Step-by-step explanation:
Fill in the number and evaluate:
v = √(64×30) = √1920 ≈ 43.82 . . . . ft/s
_____
Of course, √(64h) can be simplified to 8√h. You know that √30 lies between 5 and 6, so the velocity lies between 8·5 = 40 and 8·6 = 48. There is only one answer choice in that range.
General equation of a circle with centre (h, k) is given by:

Now, the origin is the centre and radius is 20, so substituting these points in yields:

C is the answer to your question
