Answer:
1.324
Step-by-step explanation:
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 : 0.125
explanation: it’s actually really easy all you have to do is
take the fraction and divide it like :
1/8 = 1 divided by 8 = 0.125
Answer:67 is correct D
Step-by-step explanation:use parallel, so 71+x=180-42 x=67 67+71=138, 67= to your answer
First you add all of them and then divide by how much numbers you have
