I believe the answer is 12.56 due to the fact that you would use the formula v=3.14 x 2^2

To find the answer u are looking for we must first come up with out eqaution.
lets use the equation (3.14)(2^2)=30. first we must do the 2 squared which gives us 4 resulting in (3.14)4=30 now we multiply pi with 4 resulting in 12.56=30 now we do the division... and my answer is 2.39 i am not sure if this is right though so take caution when using my response

admission to a carnival is $5 and each game at the carnival cost $0.85. you have $15 to spend on admission and games. what is th
aleksandrvk [35]
So, you have $15 in total to spend.

1. Subtract your admission fee. 15-5=10
2. Divide 10 by .85 to get the number of games you were able to play. 10 divided by .85 = 11.76
3. Now, since it says the minimum you were able to play, round to the nearest digit. 11.76=11

You were able to play a minimum of 1 game and a maximum of 11 games.

Assume a and b are whole numbers, and a&gt;b. Which expression has the least value?
dedylja [7]

a > b

A . a^5b^3/ab^4 = a^4/b

B. a^4 / a*a*a*a = a^4 / a^4 = 1

C. ab^2 / a^2b = b/a

D. b*b*b/b^3 = b^3/b^3 = 1

B and D, doesn't matter what values of a and b it's always equal 1

Lets say a = 2 and b = 1

A. a^4/b = 2^4 / 1 = 16/1 = 16

C. b/a = 1/2 = 0.5

So C has the least value

Answer:

ab^2 / a^2b
