Answer:
836 m
Step-by-step explanation:
Given that the tracks are similar, therefore, the ratio of the lenght of all corresponding sides of the inside track to the outside track are equal, and have the same scale factor.
Only 1 side of the inside track is given as 395 m. It corresponds to the side of the outside that measures 553 m. Therefore:
scale factor = 395:553 =
Find the remaining two sides of the insider tracks by multiplying the lenght of the side of the outside tracks that corresponds to each by the scale factor.
Thus:
280*0.7 = 196 m
350*0.7 = 245 m
The remaining 2 side lengths of the inside tracks are 196 m and 245 m.
If Chang completes 1 lap around the inside tracks, he would have gone: 395 + 196 + 245 = 836 m.
Answer:
4500
Step-by-step explanation:
As long as your number isn't less than 500, it will always round up.
Let be the length of one leg, and be the length of the hypothenuse. Finally, let be the measure of the angle between them. Then, the following relation holds:
