2/5. You can check my answer by subtracting 1/5 from 3/5 and subtracting 3/5 from 5/5.
Answer:
a=8.182 and b=8
Step-by-step explanation:
Weight of the Empire State Building =
pounds.
Weight of the One World Trade Center building= 88,200,000 pounds.
=
The addition of the two:
Comparing with the form: 
a=8.182 and b=8
Answer:
k = - 14
Step-by-step explanation:
given that (x - 5) is a factor of the polynomial then x = 5 is a root and
x³ - x² + kx - 30 = 0 for x = 5, that is
5³ - 5² + 5k - 30 = 0
125 - 25 + 5k - 30 = 0
70 + 5k = 0 ( subtract 70 from both sides )
5k = - 70 ( divide both sides by 5 )
k = - 14
The distance covered by the hiker if he traveled a horizontal distance of 120 ft at and angle of 6° will be given by:
cos θ=adjacent/hypotenuse
let the hypotenuse be h, adjacent =120 ft, θ=6°, thus plugging in the values we shall have:
cos 6=120/h
h=120/cos 6
h=120.661 ft
Answer: 120.661 ft
