Answer:

  • 76 in³

Step-by-step explanation:

Volume of gas varies directly as the cube of its radius.

  • V = kr³

<u>Find k:</u>

  • 108 = k(3³)
  • k = 108/27
  • k = 4

<u>Volume of the smaller balloon:</u>

  • V = 4r³
  • V = 4(2³) = 32 in³

<u>The difference in volumes is the volume of released gas:</u>

  • 108 - 32 = 76 in³

Morgan, Dakota and Taylor showed their work solving the equation 7x+5x+1=73. Identify the student with the invalid first step an
antoniya [11.8K]

Answer:

Step-by-step explanation:

Given the equation solved by Morgan, Dakota and Taylor expressed as 7x+5x+1=73, to get the value of x, the valid steps are as shown;

7x+5x+1=73

take the sum of 7x and 5x

12x+ 1 = 73

subtract 1 from both sides

12x+1-1 = 73-1

12x = 72

Divide both sides by 12

12x/12 = 72/12

x = 6

Based on the calculation above, the students with invalid first step is Dakota.

<em>Dakota added 5x with 1 to get 6x which is an invalid step because 1 is not attached to a variable x. A function cannot be added to a constant hence making his first step invalid.</em>
