(9×10)+(7×1)+(3×0.1)+(5×0.01)+(6×0.001)
For these problems you'll need to know that the volume on a triangle can be figured out by plugging in given information into the equation: v=1/2 bxh
Answer:
C 14
Step-by-step explanation:
7 ×4 ×1/2=14
because triangle area formula is A=1/2×B×H
B= base
H= height
Answer:
9 sq ft
Step-by-step explanation:
H of ABC =
(3 * h)/2 = 18 sq ft
3 * h = 18 * 2
h = 36/3
h = 12
3/12 = 2/x
(12 * 2)/3 = 8
Area of EFG = (2*8)/2
= 9 sq ft
