Question 257360: #1)Research for a given orchard has shown that, if 100 pear trees are planted,then the annual revenue is $90 per tree. If more trees are planted they have less room to grow and generate fewer pears per tree. As a result, the annual revenue per tree is by $0.70 for each additional tree planted. No matter how many trees are planted, the cost of maintaining each tree is $7.40 per year. How many pear trees should be planted to maximize the profit from the Orchard for 1 year?

Question 259923: The legs of the triangle are 18 inches and 2 feet. The hypoteneuse is shown as a broken post. What was the original height of the post. Justify your answer.
18^ + 24^ = c^
324 + 576 = 900
c^=900
c^ = the square root of 900
c = 30"
Therefore, the original height of the post is 30".
Is this right?
