Mr. Patrick teaches math to 1515 students.
katrin2010 [14]
Sum of all grades / number of students = average grade

Average grade = 80
number of students = 1514 (excluding payton)

80 * 1514 = 121120

Average grade = 81
number of students = 1515

81 * 1515 = 122715

Sum of 1515 students = 122715
Sum of 1514 students = <u>121120</u>
Difference:                          1595   *Paytons grade

OlgaM077 [116]

The change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.

Given that a weather balloon is descending from the atmosphere, and its altitude changes by -6 meters every second, to determine what is the change in altitude after 135 seconds the following calculation must be performed:

  • Amount of time x change per second = total change
  • 135 x (-6) = X
  • -810 = X

Thus, the change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.
