Answer:
x=7/3
Step-by-step explanation:
3(x-4)=-5
3x-12=-5
3x=7
x=7/3
256. Since each side is congruent, the length equals 8. 8 times 8 equals 64. Divide it by 2 to find the area of the triangle. 64 divided by 2 equals 32. Since there are 8 congruent triangles, 32 x 8 equals 256.
The answer to your question is 8.9
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%
