Your new job is 25 miles away from your house. If you drive to work at a rate of 50 miles per hour, how long does it take you to
sergeinik [125]

the time taken to get to your work place is 0.5 hour.

The given parameters;

  • distance between  your new job and your house  = 25 miles
  • speed to work, v = 50 mph

The time taken to get to work is obtained by dividing  the distance between your new job and your house, by speed of your motion to work.

Distance = speed x time

Time = \frac{Distance }{speed} \\\\T ime = \frac{25}{50} \\\\Time = 0.5 \ hour

Thus, the time taken to get to your work place is 0.5 hour.

Please help explain!!!!
Inessa [10]

Answer:

x=81 degrees z=99 degrees y=68 degrees

Step-by-step explanation:

first we know 36+63+x is 180 degrees by triangle sum ( the sum of the three angles of a triangle is 180)  so x would be 81 degrees. then we know x+z=180 degrees by sum of a line( a line is 180 degrees on either side) making z=99 degrees. Then doing triangle sum again we know 13+99+y=180 degrees making y=68 degrees
