cos 51° = (adjacent side)/(hypotenuse) = x/43
0.629320.91 = x/43
and x = 27.1

Answer:

1) Yes, 1/2 and 2

2) b=1/2 × t

t=2 × b

Step-by-step explanation:

1) Yes, because every package of a toy equals 2 batteries. The constant of proportionality is 1/2 and 2 because 1 ÷ 2 = 1/2 and 2 ÷ 1 = 2 (amount of toys divided by amount of batteries and vice versa)

2) b = 1/2t, because for every battery, there is 1/2 a toy.

t = 2b, because for every toy, there are 2 batteries

note: you can't actually have 1/2 a toy, but we write it like that for the sake of showing the relationship of toy to battery.
