Answer:
20%
Step-by-step explanation:
Use the formula:
The "|" symbol represents absolute value and the dashed line represents a division line.
| Theoretical Value - Actual Value |
Percent Error = -------------------------------------------------- × 100
| Theoretical value |
- 100 students is the theoretical value
- 120 students is the actual value
100 - 120 = -20
-20 / 100 = -0.2
|-0.2| = 0.2
0.2 × 100 = 20
The answer is 20%

Answer:
239.34 ft²
Step-by-step explanation:
The lateral surface area of the entire cone is 188.40 ft² and the lateral surface area of the missing cone is 112.34 ft².
Therefore, the lateral surface area of the given stand cut from the right circular cone is (188.4 - 112.34) = 76.06 ft²
Hence, the total surface area of this given stand cut from the right circular cone = 76.06 + area of the two horizontal surfaces at top and at bottom.
= 76.06 + π × 4² + π × 6²
= 76.06 + 3.14(16 + 36)
= 76.06 + 163.28
= 239.34 ft² (Answer)
That is 8.51 which means it is over 4 dollars above the standard pay. All you have to do is mainly make the 15% into a decimal (which means to move the decimal places twice to the right so it is .15) and then multiplying it by 56.75. There it would show you how much it is for the supposed to be 15% tax which is 8.51. Since they gave her 12.45, then yes they gave her more than expected.
