Well on this problem recall area of a rectangle is defined by:
A = lw our w = 1/6 and our l = (x +
) we have let 'x' represent our original length.
12x + 8 = 11
12x = 11 - 8
12x = 3
x =
So our original length is
Answer:
the height of the porch is H=1.91 m
Step-by-step explanation:
neglecting friction and assuming that the porch is horizontal, then the horizontal speed is v₀= 4 m/s and it does not change , thus he hits the base at
t= L/v₀ , L= horizontal distance
then for vertical motion , since the vertical velocity vy is 0 , the initial height is H ( the height of the porche) and the final height hf is 0 , we have
hf = H + vy*t - 1/2*g*t²
0 = H + 0 -1/2*g*t²
H = 1/2*g*t² = 1/2*g*(L/v₀)²
replacing values with g= gravity = 9.8 m/s²
H = 1/2*g*(L/v₀)² = 1/2*9.8 m/s² *( 2.5 m/ 4 m/s)² = 1.91 m
therefore the height of the porch is H=1.91 m
<span>10/9, or 1 1/9 lbs of walnuts.
The original ratio of walnuts to fruit is (2/3)/(3/5) and we wish to retain that ratio. So let's set up an equality to express that.
(2/3)/(3/5) = X/1
Now solve for X.
(2/3)/(3/5) = X/1
(2/3) * (5/3) = X/1
10/9 = X/1
10/9 = X
So we need 10/9 pounds of walnuts.</span>
