Problem
QUESTION 7 10 points Save Answer Use a proportion to solve the problem. When a pole \( 6 \frac{1}{4} \mathrm{ft} \) high casts a shadow \( 1 \mathrm{ft} \) long, how long a shadow is cast by a tree \( 50 \mathrm{ft} \) tall? \( 9 \mathrm{ft} \) \( 8 \mathrm{ft} \) \( 9 \frac{1}{4} \mathrm{ft} \) \( 8 \frac{1}{4} \mathrm{ft} \)
Solution
Step 1 ：\(\frac{6 \frac{1}{4}}{1} = \frac{50}{x}\)
Step 2 ：\(x = \frac{50}{6 \frac{1}{4}}\)
Step 3 ：\(x = 8\)
