Since Mark's brother is five years older than Mark and their combined ages add up to 23 than Mark must be 9.
Since 9 + 14 = 23, and 14 - 9 = 23
Mark brother is 14 but Mark is 9
Mark is 9 years old.

In this question, the oil production at 2004 (which was 731000barrel/day) was reduced at 2005(into 537500 barrel/day). You are asked the percentage reduction. To answer this, you need to determine how much the decrease in barrel/day then divide it by the initial production before reduced(production at 2004)
The reduction would be: 731,000 barrels/day - 537,500 barrels/day = 193,500 barrels/day
Then divide it with initial production: (193,500barrels/day )/(731,000 barrels/day) * 100% = 26.47%
Answer:
The area is 154 cm²
Step-by-step explanation:
Since the formula for the area of a circle is pi times the radius squared, divide the diameter in half to get the radius (7). Then, square the radius (49). Next, multiply that by pi (153.938). After that round to the nearest whole number (154). Hope that helps!
