Answer: c
Step-by-step explanation:
just did it
Newton's cooling model is ΔT = ΔTo * e ^ (-k t)
ΔTo = 200°F - 70°F = 130°F
k = 0.6
t = 2 hours
=> ΔT = 130 * e ^ (-0.6 t) = 130 * e^ (-0.6 * 2) = 130 * e ^ (-1.2)
ΔT = 39.15°F
ΔT = T - Tenvironment => T = ΔT + Tenvironment = 39.15°F + 70°F = 109.15°F ≈ 109 °F.
Answer: T = 109 °F
Answer:
0.375
Step-by-step explanation:
1/4= 0.25
0.25/2=1/8
0.125=1/8
0.125x3=3/8
0.375=3/8
The area would be 1/2 the original
