Answer:

x = 7

Step-by-step explanation:

All the angles in a triangle added together equals 180 so:

64 + 71 + 9x - 18 = 180

add like terms

9x + 135 - 18 = 180

9x + 117 = 180

subtract 117 from both sides

9x = 63

divide by 9

x = 7

A car travels a distance on a road of 12.42 miles at a slope of 6.4%. The car has a maximum speed of 203 mph. Assume the car wil

Neko [114]

Answer:

4 mins 31 seconds

Step-by-step explanation:

Maximum speed is 203 mph equivalent to

$203*\frac {5280}{3600}=297.73 ft/s$

Time taken to attain maximum speed, $t=\frac {v}{a}$ where v is velocity and a is acceleration hence

$t=\frac {297.73}{2.93}=101.6155 s$

The distance traveled when at top speed

$d=\frac {v^{2}}{2a}=\frac {(297.73)^{2}}{2*2.93}=15127.16 \approx 15127.2 ft$

Total distance is provided as 12.42 miles converted to ft is 12.42*5280=65577.6 ft

Total distance-distance moved to attain maximum speed will be

65577.6 ft-15127.2 ft=50450.44 ft

Time taken during maximum speed

$t=\frac {50450.44}{297.73}=169.45 s$

Total time=101.6155 s+169.45 s=271.06 s

271.06/60=4 mins 31 seconds
