Answer to Problem 30PPS
15.6 feet
Explanation of Solution
Given:
Height of an office building: b
Height of the granite statue: g
Total height of the building and the statue: 326.6 feet
Difference in heights between the building and the statue: 295.4 feet
Calculation:
Let b be the height of the building and g be the height of the granite statue.
The total height of the building and the statue can be represented by the equation:
The difference in heights of the building and the statue can be represented by the equation:
To find the height of the statue use elimination method as follows:
Subtract equation (2) from equation (1), so that b can be eliminated.
Conclusion:
Therefore, the granite statue is 15.6 feet tall .

To find the height of the building
b.
Answer to Problem 30PPS
311 feet
Explanation of Solution
Given:
Height of an office building: b
Height of the granite statue: g
Total height of the building and the statue: 326.6 feet
Difference in heights between the building and the statue: 295.4 feet
From subpart (a), the height of the granite statue is 15.6 feet.
Calculation:
Let b be the height of the building and g be the height of the granite statue.
The total height of the building and the granite statue is 326.6 feet, which can be represented as follows:
