Answer:
x = 16
Step-by-step explanation:
Given that the sum of the exterior angles is 360°
Sum the given exterior angles and equate to 360
47 + 93 + 46 + 3x + 62 + 4x = 360, that is
248 + 7x = 360 ( subtract 248 from both sides )
7x = 112 ( divide both sides by 7 )
x = 16
Answer:
10 degrees
Step-by-step explanation:
The angle between hour and minute hand in 4:20 is 10 degrees. For a minute, the hour hand rotates by 30/60 = 1/2 degrees. hence, for 20 minutes it rotates by an angle of 20*1/2 = 10 degrees.
Answer: 23.2 miles per hour
Step-by-step explanation:
He ran 100 meters in 9.63 seconds.
First convert the number of meters he ran to miles:
= 100 * 3.28
= 328 feet
= 328/5,280
= 0.062121212 miles
Convert the seconds to hours:
= 9.63 / 60
= 0.1605 minutes
= 0.1605/60
= 0.002675 hours
Speed in miles per hour is:
= 0.062121212 / 0.002675
= 23.22
= 23.2 miles per hour
