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
To simplify this expression, you have to remember that when
a number or a variable is raised to the negative exponent you have to
reciprocate the number. In this expression, c^-8 will be reciprocated so it
will become part of the numerator. Therefore, the final answer would be
12c^8/d^2.
Answer:
The third answer: x+1
Step-by-step explanation:
Remember when writing roots, the signs are backwards. This is because you start with (x-__) and fill in the root.
So for x = -1, it'll be written as (x+1) [aka (x- -1)]
For x = -3, it'll be written as (x+3)
For x = 5, it'll be written as (x-5)
The only answer that is one of these is the the third answer
