Answer:
71 %
Step-by-step explanation:
Paper 1 :
65% of 120 = 0.65 X 120 = 78
Paper 2 :
80% of 80 = 0.8 X 80 = 64
Total Percentage:
Add the two scores 78 + 64 = 142
Add the what it was out of 120 + 80 = 200
Use (Score / Total marks available) X 100
(142 / 200) X 100 = 71

The average change of temperature per hour is the difference in temperature divided by the difference in hours.
3 a.m. 10 a.m. ----> difference in time: 10 - 3 = 7
-13 22 ----> difference in temperature: 22 - (-13) = 35
average change of temperature per hour: 35/7 = 5
Answer: 5 degrees per hour
Step-by-step explanation:
let
(-7,-8) =(x1, y1)
and (-6,7)=(x2, y2)
by the formula
d=√(y2-y1) ²+(x2-x1) ²
=√(7+8)²+(-6+7)²
=√15²+1²
= √225+1
= √226
