Answer:
a this is because bigger negative numbers are smaller
Answer:
θ = 85.93° (≈ 86°)
Step-by-step explanation:
arc length : 2πr = θ : 360°
7.5 : 2πr = θ : 360°
θ = (7.5 * 360°) / (2π*5) = 2700 / 31.42 = 85.93°
θ ≈ 86°
120=x+y and 10=.05x+.10y
120-x=y then subsitute 10=.05x+.10(120-x) distruibte and solve you can do it feel free to go off of my math.
x(nickels) y(dimes)
They would be:
Mabel
Liling
Peta
But Mabel’s answer is Liling’s answer if it was rounded. And for Peta: 8/9 is equal to both (either rounded up to or not)
