Answer 4

Q4 choose one of the responses

Answer 5

For Question 4, the best response given the options you provided would be:

• Response: \( r = \frac{C}{2 \pi} \)

This response implies isolating the radius (r) in the formula for the circumference of a circle. If this specific option was not listed, the closest correct response would likely involve isolating the variable \( w \) in some way related to the box volume formula. Please specify the exact options available if needed.

Answer 6

Q4 is Given the formula for the volume of a box, V=lwh , which equation best represents the remaining units when justifying your rearrangement to solve for the width?(1 point) Responses in.3in.2=in. Start Fraction in. cubed over in. squared End Fraction equals in. in.3=in.3 in. cubed equals in. cubed in.=in. in. equals in. in.3in.2=in.3in.2

Answer 7

Thank you for providing the response options.

For Question 4, given the formula for the volume of a box \( V = lwh \) and the goal to rearrange to solve for the width \( w \), the best response that represents the remaining units when justifying this rearrangement is:

• Response: \( \text{in.}^3 = \text{in.}^2 \cdot \text{in.} \)

This indicates that volume (cubic inches) is equal to area (square inches) multiplied by width (inches), effectively justifying the rearrangement when solving for width \( w \).
