Ineed a walkthrough on this, i have tonight to get it finished and i'm not sure where to begin..a steel beam can be cut to different lengths for a project. assuming the weight of a steel beam is proportional to its length, what information would you need to know to write an equation that represents this relationship? [following a lesson titled 'solving problems about proportional relationships']

Which of the following is the shape of a cross section of the figure shown below

*let m∠cob = 50°30’, m∠aob = 70° and m∠aoc = 20°30’. could point c be in the interior of ∠aob? why? a. point c could be the interior of aob but it is not the only case b. point c is the interior of aob c. point c is not the interior of aob d. the given is not possible for the plane geometry answer

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
