The total length of the rope = 32 ft
It is cut into two sections, say x and y
But one section is seven times the other, say y=7x (shorter section being x)
Solving for x
x+y =32
x+7x = 32
8x=32
x=32/8 = 4 ft.
Therefore, the shorter piece is 4 ft long.
d₁ = -16t² + 122t
d₂ = -16t² + 84t
d = d₁ - d₂
d = -16t² + 122t - (-16t² + 84t)
d = 38t
After five seconds, t=5,
d = 38(5) = 190
Answer: 190 feet
7 gallons of gasoline=350 miles
1 gallon of gasoline=50 miles
0.02 gallons =1 mile
4.00×0.02=0.08 cents per mile
1/8 the fraction?
two eighths = 2/8=1/4
