During a day a student spends 7 hours sleeping, ¹/4 of the day studying and of the time travelling. What fraction of the day is
1 answer:
Answer:
Step-by-step explanation:
- Time Spent Sleeping=7 hours
- Time Spent Studying=
of the day
- Time Spent Travelling=
There are 24 hours in a day, therefore:
- Time Spent Studying=
- Time Spent Travelling=
The total hour used for sleeping, studying and travelling=7+6+6=19 hours
Hours used for other things=24-19=5 hours
Therefore, the fraction of the day used for other things=

Answer:
m<X =
Step-by-step explanation:
From the given isosceles triangle, we have;
<W and <V as the base angles
So that,
m<W = m<V = 27 (base angles of an isosceles triangle are equal)
Thus,
m<X + m<V + m<W = 180 (sum of angles in a triangle)
m<X + 27 + 27 = 180
m<X + 54 = 180
m<X = 180 - 54
= 126
m<X =
<u>Given</u>:
The coordinates of the points A, B and C are (3,4), (4,3) and (2,1)
The points are rotated 90° about the origin.
We need to determine the coordinates of the point C'.
<u>Coordinates of the point C':</u>
The general rule to rotate the point 90° about the origin is given by
Substituting the coordinates of the point C in the above formula, we get;
Therefore, the coordinates of the point C' is (-1,2)
