B.20 2/3
C.22 2/3
D.21 10/15
Answer:
A. 24+24+120+160+200
Step-by-step explanation:
Surface area of the triangular prism= addition of the area of each shape that forms the prism
There are two triangles
Area of a triangle=1/2*base*height
=1/2*8*6
=1/2*48
=24
Area of two triangles=24+24
There are 3 rectangles with different dimensions
Back rectangle=length×width
=20×6
=120
Bottom rectangle=length ×width
=20x8
=160
Top rectangle=length × width
=20×10
=200
Surface area =Area of two triangles + Back rectangle + Bottom rectangle + Top rectangle
=24+24+120+160+200
15-3n=n-1
The number of the pieces will be equal to 8.
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the ribbon size is 5(¹/₃) and the piece to be cut is 2/ 3 feet in size.
The number of pieces will be calculated by dividing the total size by the per piece size.
N = [ 5(¹/₃) / ( 2/ 3) ]
N = [ (16/3) / (2 / 3)]
N = 16 / 2
N = 8
Therefore, the number of pieces will be equal to 8.
