First, let's find the scale of the smaller to the bigger triangle:
6:6+4 = 6:10 = 3:5
3/5 = x/2
6 = 5x
x = 6/5
(x+y) is the coefficient of xy
Answer:
m=5/2
Step-by-step explanation:
the equation of slope is (y2-y1)/(x2-x1)
here are the points given: (0,5), (2,10)
let's label the points:
x1=0
y1=5
x2=2
y2=10
now substitute into the equation (m is the slope)
m=(10-5)/(2-0)
subtract
m=5/2
the slope is 5/2
1 ft = 12 in
6 in = 6/12 = 0.5 ft
9 in = 9/12 = 0.75 ft
D = M/V ⇒ M = DV
V = 0.5 * 0.5 * 0.75 = 0.1875 cubic foot
M = 41.7 * 0.1875 ≈ 7.8 pounds
Answer: B.
