Divide the shape into a rectangle and a triangle.
A(rectangle) = bh
A = 8*3
A = 24
A (triangle) = (bh)/2
A = (3*3)/2
A = 4.5
24 + 4.5 = 28.5
The domain of A is {-3, 0, 2, 5}.
Answer:
<h2>174ft²</h2>
Step-by-step explanation:
Area of a Rectangle = L x W
L = 8
W = 6.5
Area of a Rectangle = 8 x 6.5 = 52
Surface Area = Area of a Rectangle x Number of Rectangles
Surface Area = 52 x 2 = 104
Area of a Rectangle = L x W
L = 8
W = 5
Area of a Rectangle = 8 x 5 = 40
Surface Area = Area of a Rectangle x Number of Rectangles
Surface Area = 40 x 1 = 40
Area of a Triangle = B x H x 1/2
B = 5
H= 6
Area of a Triangle = 5 x 6 x 1/2 = 15
Surface Area = Area of a Triangle x Number of Triangles
Surface Area = 15 x 2 = 30
Surface Area = Sum of Surface Areas =
104 + 40 + 30 = 174ft²
Answer:
50%
Step-by-step explanation:
500 guitar picks
order 15 boxes with 9 picks each
sell 19 boxes with 10 picks each
-> the store ordered about 150 picks (15 x 9 -> 15 x 10)
-> the store sold about 200 picks (19 x 10 -> 20 x 10)
it is reasonable, since they have 50 fewer picks which is about 450.
