Step-by-step explanation:

We will make use of the following rules in solving these questions:

Inverse Variation: ==>

Direct Variation: =>

Direct, then inverse variation: ==>

Joint Variation: ==>

The solution goes thus:

1. m varies directly to a

2. p varies inversely as q.

3. directly as s and inversely as t.

4. z varies jointly as

5. F varies directly as the

6. d varies jointly r and t

7. P is inversely proportional to h.

8. P varies directly as V

9. d varies directly as the square of  t

10. s varies jointly as  b and d and inversely as the  square L

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
