Answer:
C = π(6)
C = 6π
C = 18.84
Step-by-step explanation:
The circumference is the distance around the circle. It relates the number of times the diameter will encircle the circumference as 3.14 or π. As a result, the formulas for the circumference of a circle are C = 2πr or C = πd. The information given is the diameter so use C = πd by substituting d = 6.
C = π(6)
C = 6π
C = 18.84
Plug in 4 for X and you get 44
Answer:
Answer is D (got it right on plato)
Step-by-step explanation:
There are 4 of each king and queen in each standard deck of 52 cards.
4+4=8
8/52=0.1538 or 15.38%
Twenty cards are chosen from a pack of cards at random
In A there are 0 kings and 1 queen
0+1= 1; 1/20=.05 or 5%
In B there are 2 kings and 4 queens
2+4=6; 6/20=0.3
In C there are 0 kings and queens
0/20=0
In D there are 2 kings and 1 queen
2+1= 3; 3/20=0.15 or 15%
D is your answer because it is the closest to the probability (0.1538 or 15.38%)
Use the formula r = d/t. Your rate is 24 miles divided by 2 hours, so: ... d = 10 miles per hour × 4 hours = 40 miles. Next, you ride 18 miles and travel at a rate of 12 miles per hour.
