In a game, 3 people are chosen in the first round. Each of those people chooses 3 people in the second round and so on. How many people are chosen in the 6th round?

729 people chosen

Step-by-step explanation:

4 calculations in head when 3^2 = 9

3 calculations in head when 3^3 = 27

2 calculations in head when 3^4 = 81

1 calculations in head when 3^5 = 243

Answer found 3^6 = 729.

3  = 1st       = 3^1

9  = 2nd    = 3^2         3(3)

27  = 3rd   = 3^3         9(3)

81  = 4th    = 3^4        27(3)

243 = 5th  = 3^5       81(3)

729 = 6th = 3^6        243(3)

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
