The time, in minutes, that it takes a
paperboy to complete his route can
estimated using the formula
(-3)' +10, where b is the
number of square blocks he delivers to
and h is the average number of houses
per block. What is the average number
of houses per block on a route that
contains 2 square blocks and takes 82
minutes to complete?

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

i think it is 18

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
