403, 892 rounded to the nearest thousand is 404,000.
The three is in the thousands place, and the 8 in the hundreds place tells us us to round up. The three becomes a 4 and everything behind it a 0. :)
Least to greatest

Answer:
The tree is 17.5 ft tall
Step-by-step explanation:
We can use proportions to solve this.
Notice that Emily (5 feet tall) and her shadow (8 feet long) constitute the two legs of a right angle triangle (see attached image).
The nearby tree (unknown height H), will also cast a shadow (28 ft long) with the same inclination as Emily does due to the unique position of the sun relative to them.
Then we can use the proportion associated with the sides of similar triangles:
![\frac{5\,ft}{8\,ft} =\frac{H}{28\,ft}](https://tex.z-dn.net/?f=%5Cfrac%7B5%5C%2Cft%7D%7B8%5C%2Cft%7D%20%3D%5Cfrac%7BH%7D%7B28%5C%2Cft%7D)
Then, we can solve for H in the equation:
![\frac{5\,ft}{8\,ft} =\frac{H}{28\,ft} \\H=\frac{28*5}{8} \,ft\\H=17.5 \.ft](https://tex.z-dn.net/?f=%5Cfrac%7B5%5C%2Cft%7D%7B8%5C%2Cft%7D%20%3D%5Cfrac%7BH%7D%7B28%5C%2Cft%7D%20%5C%5CH%3D%5Cfrac%7B28%2A5%7D%7B8%7D%20%5C%2Cft%5C%5CH%3D17.5%20%5C.ft)
