Answer:
18 rubber band bracelets
Step-by-step explanation:
1 hour = 4 bracelets
4.5 hours = ?
4.5 hours/× 4 bracelets
_______
1 hour/
4.5×4 bracelets = 18 bracelets
In an hour Jessica makes four bracelets and in 4.5hours she makes how many bracelets ,we don't know , obviously in 4.5hours she would make more so if more less will divide.
so 4.5hours over 1hour times 4 bracelets. so hour will cancel hour and now 4.5 times 4 bracelets is equal to 18 bracelets
Perimeter=4*side so
side=p/4 and we are told p=16x+32y so
s=(16x+32y)/4
s=4x+8y
s=4(x+2y)

Answer:
32.7°
Step-by-step explanation:
Use the formula for law of cosines, for this question we need so solve for angle B, so use...
b² = a² + c² - 2(a)(c)Cos B
We are given a, b, and c, so plug them in...
55² = 90² + 50² - 2(90)(50)Cos B
Now simplify...
3,025 = 8100 + 2500 - (9000)Cos B
-7,575 = -(9000)Cos B (subtract 8100 and 2500 from both sides)
0.841666667 = Cos B (divide both sides by -9000)
Cos^(-1) 0.841666667 = B (use cosine inverse function on calculator)
