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']

We have been given that the weight of the steel beam is proportional to its length.

Therefore, w ∞ l

or, w = kl, where k is the constant of proportionality.

So, to know the relationship between the weight and the length, we need to know the constant of proportionality.

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).

answer: are you
