Answer:
see explanation
Step-by-step explanation:
(a)
The shaded figure is a trapezium with area (A)
A = 0.5 h(a + b)
where h is the perpendicular height and a, b the parallel sides, thus
A = 0.5 × 10 × (8 + 14) = 5 × 22 = 110 cm²
(b)
The volume (V) of the prism is calculated as
V = area of end face × depth
= 110 × 3 = 330 cm³
Answer: the answer is D.108
Answer:
a
Step-by-step explanation:
4p=19-5
4p=14
p=14/4
p=3.5
Answer:
P = 4x - 2
Step-by-step explanation:
Perimeter is all the side lengths added together.
Step 1: Set up expression
P = 2x - 5 + 5 - x + 3x - 2
Step 2: Combine like terms
P = 4x - 2
2.56 times 0.03 is 0.0768 then round to hundredth is 0.08 i think
