Answer:
1240.4 mm²
Step-by-step explanation:
The surface area of a pyramid = Area of the all sides + Area of base
Each side is a triangle.
With a regular pentagonal pyramid, the area of each triangle is
For the 5 triangles,
Substituting given values,
Area of base = 440.4 mm²
Surface area of a pyramid = 800 + 440.4 mm² = 1240.4 mm²
You already know that y equals -4. It says that x equals 3, so multiply the -4 by 3 and because it has a negative number and a positive number it will equal -12. Remember anytime you see a letter after a number it means multiply. The complete problem should be -10 because 2 is a whole number you subtract it from -12. Hope that helped you out some.
Answer:

Total cost job=
Retail price of parts+labor cost+manufacturing overhead
Total cost job 82
Retail price of parts 0
Labor cost=7.5×6.5=48.75
Manufacturing overhead ?
82=0+48.75+?
?=82−48.75
?=33.25
Manufacturing overhead is 33.25
Now find manufacturing overhead rate from the cost of labor
33.25÷48.75=0.682×100=68.2%
The answer 68.2%
