40 * 7.85 = 314
32.24 + 24.02 + 24.53 = 80.79
314 - 80.79 = 233.21

Answer:
Step-by-step explanation:
Given:
Number of feathers = 
Number of caps = 
Number of feathers in each cap = 3
Now, solving by setting up a proportion.
1 cap has 3 feathers. 'c' caps has 'f' feathers.
This gives,
Solving by cross multiplication, we get:
Therefore, the equation representing the number of feathers 'f' Erica needs to make 'c' caps is given as:
Answer:
(9b + 3c + 10d)cm
Step-by-step explanation:
Given the sides of a triangle expressed as (2b+c), (7b + 4d) and (6d+2c). The perimeter of the triangle is the sum of all the sides of the triangles.
Perimeter of the triangle = 2b+c + 7b+4d + 6d+2c
Perimeter of the triangle = 2b + 7b + c + 2c + 4d + 6d
Perimeter of the triangle = 9b + 3c + 10d
Hence the perimeter of the triangle is (9b + 3c + 10d)cm
