n=number of hours
inequality = 3n+10=40
Solution = n = 10. So 10 hours.
Area of a trapezoid: [(top +bottom)*height]/2
suppose the length of one base is x, then the other base is 5x-19
[(x+5x-19)*18]/2=477
[6x-19]*18=954
6x-19=53
6x=72
x=12
The longer base is 5*12-19=41
One ways is to find the factors of 36
1,36
2,18
3,12
4,9
6,6
add them
1+36=37
2+18=20
3+12=15 correct
4+9=13
6+6=12
the numbers are 3 nd 12
Step-by-step explanation:
here's the solution,
in the given figure , sum of all angles formed with O measures 360°
because, it forms a complete angle
so,
=》mPOQ + mQOR + mROS + mSOT + mTOP = 360°
=》mPOQ + mQOR + mROS + mSOT + mTOP = (90° × 4)
=》mPOQ + mQOR + mROS + mSOT + mTOP = 4 × right angle
(cuz.. right angle = 90°)
