Divide 132kg in a ratio of 3:3:5
borishaifa [10]
3 + 3 + 5 = 11 (11 total parts of the ratio.)

132 ÷ 11 = 12 (one part of the ratio)

Multiply 12 by the number of parts in the ratio:

12 × 3 = 36
12 × 3 = 36
12 × 5 = 60

Therefore, the final answer is 36:36:60 kg.

Someone please help! important.
IrinaVladis [17]

Answer:

x = 4.9t²

Step-by-step explanation:

x is directly proportional to t²

x = kt²

When t = 2 , x = 19.6

Substitute into the equation

x = kt²

19.6 = k * 2²

19.6 = k * 4

19.6 = 4k

k = 19.6/4

k = 4.9

Substitute the value of k into the equation:

x = kt²

x = 4.9t²
