Answer:
57 in³
Step-by-step explanation:
Since the volume of gas and the cube of its radius vary directly, we can set up an initial equation to find the constant of variation:
V = kr³, where v=volume, r=radius and k=contant of variation
Given that a balloon with a radius of 3 inches can hold a volume of 81 cubic inches, we can plug these values into the equation and solve for 'k':
81 = k3³ or 81 = 27k or k = 3
Given 'k', now we can find the volume of the balloon with a radius of 2:
V = (3)(2³) = 24 in³
Since the question asked how much gas must be released to reduce the radius, we would find the difference of 81 and 24:
81 - 24 = 57 in³
Answer:72 are boys.
Step-by-step explanation:
40%of 180 is 72.
Cost of chicken wings at Buffalo Bills = 8 wings for $7
Cost of 1 wing at Buffalo Bills = 
Cost of chicken wings at Buffalo Mild Wings = 12 wings for $10
Cost of 1 wing at Buffalo Mild Wings = 
Cost of chicken wings at Wingers = 20 wings at $17
Cost of 1 wing at Wingers = 
Hence, comparing all the three costs per wing, we can see that Buffalo Mild Wings is serving chicken wings at lowest price of $0.833 per wing.
2+32 would be 34 then 34+34 is 68 and 68-56 is 12 that’s your answer

Answer: 9,979,200</h3>
This is one single number. It's just a bit under 10 million
Delete the commas if necessary.
==================================================
Explanation:
If we could tell the repeated letters apart, then there would be
11*10*9*8*7*6*5*4*3*2*1 = 39,916,800
different ways to scramble up the letters.
However, we have 2 copies of b and 2 copies of i
So we have to divide by 2*2 = 4 to correct this overcounting
(39,916,800)/4 = 9,979,200
