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
Multiply by 3 so the answer is three
Size square × 4 = size triangle × 3
(2X × 4 ) = [(2X +1/3) × 3]
8X = [(6X+1)/3×3]
8X = 6X+1
8X -6X = 1
2X = 1
X= 1/2

A) <span>
The mass of the air freshener A decreases by 3.2 grams each day. Define a function, f, to represent this situation.In this function, the mass of the air freshener A (m)
is the dependent variable and the days (t) and the initial amount of the air freshener A (mi) are the
independent variables. If the mass decreases by a fixed amount each day, you only have to multiply this amount by the number of days:

B) The mass of the air freshener B decreases by 3.2% each day. Define a function, g, to represent this situation.
</span>
This function is trickier since there isn't a fixed amount of decreasing. Instead,
the rate of decreasing depends on the initial amount of the freshener (mi). You have to include this initial amount in the equation to correctly model it. This is how you do it:

Have a nice day!
Answer: x=66
explanation: x+(x-20)+(2x+10)+(x+40)=360
5x+30=360
5x=330
x=66
