Step-by-step explanation:
(given)
Let us consider :
= 
= 
=
=
=
Now, by substituting the above considerations in the above equation, we get:
where,
1
then it follows
n = 20
r = 4
then no. of solutions for the eqn = 
= 
= 10626
Answer :
no. of solutions for the eqn 10626
Use the Circumference Formula of a Circle: C=2(pi)(r). The radius is the length from the center to a point on the circle. The circumference is essentially the perimeter of the circle, so the “edge” around the circle is the circumference.
The stock of cat food will last for 149 weeks.
Step-by-step explanation:
Given,
Bags of cat food in stock = 112
Bags used each week = 
Let,
x be the number of weeks.
Therefore,

Multiplying both sides by 4/3

Rounding off to nearest whole number;
x=149
The stock of cat food will last for 149 weeks.

Step-by-step explanation:
sin15
=sin(45-30)
=sin45.cos30-cos45.sin30
=(0.707×0.86)-(0.707×0.5)
=(0.6082)-(0.3535)
=0.25
