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:
66°
Step-by-step explanation:
BAC angle is an inscribed angle, it is equal 1/2 of central angle, if inscribed and central angles have the same arc.
∡BAC=1/2 ∡BOC = 132/2= 66°

Is it the new album of BtS?
Based on the formula given of 27π = πn, we can find the value of n after substitution in an equation to be 27.
<h3>What is the value of n?</h3>
The value of n can be found by making n the subject of the formula as shown below;
27π = πn
n = 27π / π
Solving of n therefore gives:
n = 27π/π
n = 27
In conclusion, n is 27.

Answer:
97 degrees
Step-by-step explanation:
We know that U and W add up to 180 degrees so we can write:
8x+9+8x-5=180
Simplify:
16x+4=180
We can figure out x from here!
x=11
Since x=11, we can plug that in and get:
88+9=97
