Answer:
Step-by-step explanation:
Given that :
Jack had 4 hours of school.
He spent 45 minutes in the library
1/2 hour on a science lecture and;
had a lunch break of 25 minutes
The objective is to determine how much time is left for the school to get over and we are to write the answer as a fraction.
In order to do that, we will have to convert the minutes into hours,
we all know that; 60 minutes = 1 hour.
Then,
45 minutes = (45/60)hour = 3/4 hour
25/60 minutes = 1/4 hour
Therefore, the amount of time left for the school to get over is:
= 
= 
= 
=
The answer is a rectangle or a square.

Step-by-step explanation:
Given the polynomial

The rational zeros are all the possible factors of
dived by all the possible factors of
. Therefore we use the rational rots theorem to find all possible rational zeros.
To find all zeros we use the remainder theorem. Thus, we plug in all the rational zeros to determine which ones evaluate to zero. These are the real zeros. We could also use long division to find the remaining zeros as soon as we got the first zero with the remainder theorem.
Answer:
OPTION C
Step-by-step explanation:
78-39=39
so: 39+39=78 (b=39)
so: 39+b= 78
It is not true that line a intersects MN at the end point of MN.
The end points of MN are M and N. But given tha line a is a bisector of MN, then line a intersects MN at the midpoint of MN, and thus MN is splited into two congruent segments.
