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:
the tree would be 45 feet tall
Step-by-step explanation:
so the house is 30 feet and 50 feet shadow, if you divide by 2 you can see that every 15 feet gives a 25 foot shadow, since 75-50 is 25 so in turn if the tree is 45 feet tall, it will make 75 foot shadow
1 represent the number of apples at the start.
