Answer:
(a) 2.6 m^2
(b) 3.9 m^3
Step-by-step explanation:
(a)
ABCD is a trapezoid.
A = (B + b)h/2
A = (1.7 m + 2.3 m)(1.3 m)/2 = 2.6 m^2
(b)
The skip is shaped like a prism with trapezoidal bases.
V = area of base * height
V = 2.6 m^2 * 1.5 m = 3.9 m^3
Answer:
9
Step-by-step explanation:
C. Ask every 12th person who leaves school one afternoon. Roll dice to determine which person to ask first.
The number of triangles in a polygon is found by taking the number of sides and subtracting 2. 8 - 2 = 6 triangles.
11>12c because 26-15>12c which equals 11>12c
