Answer:
x=70
Step-by-step explanation:
sum is angles of a Pentagon=540°
x°+138°+2x°+80°+112°=540°
3x°+330°=540°
3x°=540°-330°
3x°=210°
3x°/3°=210°/3°
x=70

The number of seconds it takes for the waste to hit the ground for the given function is: 5 seconds.
<h3>How to Evaluate a Function?</h3>
We are given the function of height to time as, h(t) = -16t² + initial height, and we have the following:
- h(t) = 0 (height of the ground is 0)
- t = seconds the waste takes to height the ground
- Initial height = 400 feet
Plug in the values into the equation of the function
0 = -16t² + 400
Solve for t
0 - 400 = -16t²
-400 = -16t²
-400/-16 = t²
400/16 = t²
√(400/16) = t
20/4 = t
5 = t
t = 5
The number of seconds it takes is: 5 seconds.

Answer:
(a) 1.4 hours or 1 hour 24 minutes.
(b) 15 miles.
(c) (5/6)t miles.
(d) 70 - (5/6 t miles.
Step-by-step explanation:
(a) speed = distance / time
50 = 70 / t
t = 70/50
t = 7/5
t = 1.4 hours.
(b) 18 minutes = 18/60 = 0.3 hours.
50 = distance / 0.3
distance = 50 * 0.3
= 15 miles.
(c). 50 = d / (t/60)
50 = 60d / t
60d = 50t
d = (5/6) t miles.
(d) Number of miles remaining after t minutes = 70 - (5/6) t miles.
