Answer:
y^6
Step-by-step explanation:
Answer:
Step-by-step explanation:
x = small barrettes
y = large barrettes
13x + 11y = 142.......multiply by -1
13x + 12y = 149
-----------------------
-13x - 11y = -142 (result of multiplying by -1)
13x + 12y = 149
------------------------add
y = 7..........large barrettes used 7 yards
13x + 11y = 142
13x + 11(7) = 142
13x + 77 = 142
13x = 142 - 77
13x = 65
x = 65/13
x = 5........small barrettes used 5 yards
100 - 17.01 - 5 - 2 - 3 + 5 + 2 =
100 - 17.01 - 3 =
100 - 20.01 =
$ 79.99 <===

Answer: First Option
Step-by-step explanation:
The surface area of a circular cone is equal to the area of the cone surface plus the area of the circular base
Where r is the radius of the base and s is the inclined height of the pyramid.
In this case we know that:
Then the surface area of the cone is:
