Answer:
only students who have recess at 12 p.m. or later may go out
Step-by-step explanation:
Let the time after midnight be represented by t, and the temperature be y. Since the temperature increases by 1.2 degrees Fahrenheit each hour, the time taken to reach 32 degrees Fahrenheit can be gotten from:
y = 1.2t + 18
put y = 32
32 = 1.2t + 18
1.2t = 14
t = 14/1.2 = 11.67 hours
Since the recess starts at half hour or hour, hence the recess would start at t = 12 hours, i.e. at 12 p.m.
Hence only students who have recess at 12 p.m. or later may go out
Answer:
(a+b)2 = a² + b² + 2×a×b
Step-by-step explanation:
There are two shapes
rectangle and triangle
Rectangle area = Length × breadth
Triangle area = ( 1 / 2 ) × height × base
L = 12
W = 5
Area = 60
Height = 14
base = width of rectangle
base = 12
( 1 / 2 ) ( 12 ) ( 14 )
( 14 ) ( 6 )
84
Total area = 60 + 84
= 144
