Answer:
Cos 74°= Sin 16°
Sin 20°= Cos 70°
Sin A°=Cos (90°- A°)
Step-by-step explanation:
This is because the three pairs are complementary i.e they add up to 90° and in trigonometric ratios, complementary ratios are equal.

solve for "k", to find the "constant of variation",
then plug it back in the y = kx, to get the equation
now
what's is y when x = -1?
well, just plug that in the equation with the found "k" value,
to get "y" :)

Answer:
Number of juice boxes people drank at Williams party = 91
Step-by-step explanation:
Total juice boxes Williams bought = 114
Juice boxes left over at the party = 23
How many juice boxes did people drink at William's party?
Number of juice boxes people drank at Williams party = Total juice boxes Williams bought - Juice boxes left over at the party
= 114 - 23
= 91
Number of juice boxes people drank at Williams party = 91
Since 3=30/10, (30+1)/10=31/10. 31s/10=(30+1)/5 ( we get 30 because 5*6=30) = 31/5. Multiplying both sides by 10, we get 31s=62 (since 5 is a factor of 10, we can do 10/5 =2 and multiply 2 by 31). Dividing both sides by 31, we get s =2
