60 the sum is 60? Right so I’m guessing this is a trick question
This is a combination in which you choose 4 from 10.
The formula is
combinations = 10! / 4! * (10-4)!
combinations = 10! / 4! * 6!
combinations = 10 * 9 * 8 * 7 * 6! / 4! * 6!
combinations = 10 * 9 * 8 * 7 / 4 * 3 * 2
combinations = 10 * 3 * 7
combinations = 210

<h3>Answer: Step-by-step explanation:
You have to make an addition with the individual times: 56.25+59.89+58.55+55.4=230.17 seconds. Now you should to convert it into a minutes and seconds. 1 minute= 60 seconds
2 minute= 120 seconds
3minute= 180 seconds
4minute= 240 seconds
In this way you they have 3 minutes and the remainder is 50 seconds.
So, the time for the team is 3 minutes and 50.17 seconds.</h3>
Answer:
Hello! The answer is 120.
Step-by-step explanation:
s = 10 and t = 2
Substitute:
(3)(2)(2)(10)
3 × 2 = 6
2 × 10 = 20
6 × 20 = 120
Circumerence=2pi(r)
circumerence=65pi
65pi=2pir
divide both sides by pi
65=2r
divide both sides by 2
32.5=r
area=pir^2
area=pi32.5^2
area=pi1056.25
area=1056.25pi
