"T varies jointly as O and M”
1. Translate into variation equation
2. If T = 36 when 0 = 3 and M = 2, find k.
3. O is 4 when M = 3 and T = 2. What is T if 0 =
8 and M = 6.
The area (A) of a triangle varies jointly as its base (b) and height (h).
4. Express the relation as a variation statement.
5. If the area is 15 cm² when the base is 5 cm and the height is 6cm, find k.
6. if A=65 cm² when b=10 cm and h=13 cm, find A when b=8 cm and h=11 cm.


E 8
B A=kb/h
D 1/2
F T=KO/M
U 6
N A=kbh
A 44 cm²
H T=KOM​

Answer:

1. H. T=KOM

2.U. 6

36=K(3)(2)

36=k6

k=36/6

k=6

3.E. 8

2=K(4)(3)

2=K12

k=2/12

k=1/6

T=1/6(8)(6)

T=1/6(48)

T= 8

4. N. A=kbh

5. D. 1/2

15=k(5)(6)

15=k30

k=15/30

k= 1/2

6. A. 44 cm²

65=k(10)(13)

65=k130

k=65/130

k= 1/2

A=1/2(8)(11)

A= 1/2(88)

A=44
