Answer:

Blankets sell for $29 a piece, and hooded towels sell for $23 a piece.

Step-by-step explanation:

blanket = x

towel = y

5x + 13y = 444 -> x=(444-13y)/5

23x + 13y = 966

23[(443-13y)/5] +13y = 966

x = 29

y = 23

Answer:

is the name of your account from little mermaid?  :DDD

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

now just refer to the above ( also copy and paste the above on your computer some where so you have it always)

sin( D )= 28 / 53

sin( E ) = 45 / 53

cos(D) = 45 / 53

cos(E) = 28 / 53
