The designers of a skateboard park are building a ramp and need a scaled-down model of one of their ramps. The side view of the actual ramp, labeled JKL, and the side view of the model, labeled PQR, is shown below. What would be the coordinates of a new point R that will make the model version of the ramp similar to the actual ramp? Explain your reasoning using complete sentences.

The given ration, for prototype to model is = 2: 12 = 1: 6 Now, difference of x points.. (34 -10) = 24 so divide this by 6.. 24/6 =6 .. so r point will be p + 6 on right.. = 30 + 6 = (36, 20)

thank u but now how wud i explain it??

OpenStudy (ganpat):

explanation will be in ur language.. what u have written.. you have dimensions of same side of model and prototype.. get the ratio for same. It means the prototype is manufactured with a ration of 1: 6.. All the dimensions for the prototype are in the ratio 1:6... From the graph you come to know, the distance of side JL it is 34 - 10 = 24.. divide it by 6 to get the corresponding size of prototype = 24/6 = 6 ... and point P is located at 30... so R will be 30 + 6 = 36.. Convert in your language.. its all abt what u sell

@ganpat wouldn't 24/6 be 4??

OpenStudy (ganpat):

@dellzasaur: oh yes mam`.. that would be 4.. typo error !!

OpenStudy (anonymous):

@ganpat It's okay!! :)

I hope I didn't come off as mean!
