A thermometer is removed from a room where the temperature is 70° F and is taken outside, where the air temperature is 40° F. Af

fgiga [73]

Answer:

53.3324

Step-by-step explanation:

given that a thermometer is removed from a room where the temperature is 70° F and is taken outside, where the air temperature is 40° F.

By Newton law of cooling we have

T(t) = $T+(T_0-T)e^{-kt}$

where T (t) is temperature at time t,T =surrounding temperature = 40, T0 =70 = initial temperature

After half minute thermometer reads 60° F. Using this we can find k

$T(0,5) = 40+(70-40)e^{-k/2} = 60\\e^{-k/2} =2/3\\-k/2 = -0.4055\\k = 0.8110$

So equation is

$T(t) = 40+(30)e^{-0.8110t}\\$

When t=1,

we get

$T(1) = 40+(30)e^{-0.8110}\\\\=53.3324$

A big movie theater had 1,200 seats. 864 of the total number of the seats were sold. what percentage of the seats was sold

Reil [10]

Answer:

72%.

Step-by-step explanation:

We have been given that a big movie theater had 1,200 seats. 864 of the total number of the seats were sold.

To find what percentage of the total seats were sold we will find 864 is what percent of 1200.

$\text{ Percentage of sold seats}=\frac{864}{1200}\times 100$

$\text{ Percentage of sold seats}=0.72\times 100$

$\text{ Percentage of sold seats}=72$

Therefore, 72% of the total seats were sold.
