Answer:
≈ 0.9 cm²
Step-by-step explanation:
I don't know if there is any easier way to solve this, I use 8th grade slope and line method to solve. suppose A is on origin, then the coordinates of triangle ABC are (0,0) (1,3) (4,1) and polygon DEFGH intersect line BC at F and G.
F is the intersect of y=2 and line BC, while G is intersect of x=3 and line BC.
Line BC: pass (1,3) and slope (m) = (1-3)/(4-1) = - 2/3,
F(x,2)
(2-3) / (x-1) = -2/3
2x-2 = 3 x = 2.5
*<u>F (2.5 , 2</u>)
G (3,y)
(y-3) / (3-1) = -2/3 y = 5/3
*<u>G (3 , 5/3)</u>
*<u>point I (3 , 2</u>)
segment FI = 3-2.5 = 0.5 = 1/2
segment GI = 2 - 5/3 = 1/3
area ΔFIG = (1/2 * 1/3) / 2 = 1/12 = 0.083
area of polygon DEFGH (region colored RED) = 1 - 0.083 = 0.917 ≈ 0.9 cm²
Answer:
87.5 ft^3
Step-by-step explanation:
Formula:
Volume = length x width x height.
Dimensions:
Length = 3 1/2 ft = 7/2 ft
Width = 5 ft
Height = 2 1/2 ft = 5/2 ft
Substitute and Find Volume:
Volume = (7/2 ft) x (5 ft) x (5/2) ft
Volume = 87.5 ft^3
B it is similar but not congurent
Answer:
I believe it is 3.3881318e-21 but you could round that
Step-by-step explanation:
Answer:
kgm/s² or Newton
Step-by-step explanation:
According to Newton's second law of motion, F = ma
Force = mass × acceleration
Unit of mass is kilogram (kg)
Unit of acceleration is m/s²
According to the formula, we can say:
Unit of force = unit of mass × unit of acceleration
Unit of force = kg×m/s²
Unit of force = kgm/s² or Newton
