Three Arabs A,B and C were traveling
together. On the lunch time A and B
produce m and n loaves of bread respectively
for eating but C have no loaf of bread. All
the three ate together. After completing
lunch C gave A and B m+n darhams.
How shoud they divide this sum?
A molten plastic flows out of a tube that is 8.0cm long
at a rate of 13cm^3 /min, when the pressure differential
between the two ends of the tube is 18cm mercury.
find the viscousity of the plastic.
The internal diameter of the tube is 1.30mm.
the density of mercury is 13.6g/cm^3
If two forces P and Q acting at 0 are represented by line OA
and OB with φ being the angle between the two forces .
find their resultant in R in terms of P
A circle of radius r has a point O as its
centre. Points A and B are points on the
circumference.
For △OAB, OA^(−) =OB^(−) =r, AB^(−) =d, ∠AOB=θ.
What is (r/d)?
P and Q are partners in a venture, P contributed #20,000 for
nine month, and Q contributed #50,000 for one year. find each
person share of profit of #6,300
An MTN mask is erected at a point P in ilaro town. At a point
B due west, The angle of elevation of its top is β and at point
C due south, the angle of elevation is α. With the aid of an
appropriate diagam. show that the angle of elevation of the top
from a point due south of B and due west of C is
cot^(−1) [cot^2 (β) + cot^2 (α)]^(1/2)
