The answer is choice A.

We're told that the left and right walls of the cube (LMN and PQR) are parallel planes. Any line contained in one of those planes will not meet another line contained in another plane. With choice A, it's possible to have the front and back walls be non-parallel and still meet the initial conditions. If this is the case, then OS won't be paralle to NR. Similarly, LP won't be parallel to MQ.

Option 3:

m∠ABC = 66°

Solution:

Given $\overline {F A D} \| \overline {E H C}$ and ABH is a transversal line.

m∠FAB = 48° and m∠ECB = 18°

m∠ECB = m∠HCB = 18°

Property of parallel lines:

If two parallel lines cut by a transversal, then the alternate interior angles are equal.

m∠FAB = m∠BHC

48° = m∠BHC

m∠BHC = 48°

Exterior angle of a triangle theorem:

An exterior angle of a triangle is equal to the sum of the opposite interior angles.

m∠ABC = m∠BHC + m∠HCB

m∠ABC = 48° + 18°

m∠ABC = 66°

Option 3 is the correct answer.

Answer:

The top one is 135 cm^2

Step-by-step explanation:

To find the area, all you need to do is multiply the 3 different measurements. For the one in the top corner we need to multiply the length by the width by the height. The work is done below for you on that one.

A = l * w * h

A = 15 * 3 * 3

A = 135 cm^2

A) The differential equation comes from the fact that the rate of temperature change is proportional to the difference in temperatures.
$\frac{dT}{dt} = \alpha(T -52)$

B) Find general solution by separating variables and integrating $\int\frac{dT}{T-52} = \alpha \int dt \\ ln (T-52) = \alpha t + C \\ T = C e^{\alpha t} +52$ :

C) Initial condition is t=0, T = 87
$87 = C +52 \\ C = 35$

D) Total time elapsed is 10 minutes, new temperature is 84
$84 = 35 e^{10\alpha} +52$
solve for alpha
$e^{10\alpha} =\frac{32}{35} \\ \alpha = \frac{ln(32/35)}{10} \\ \alpha = -.00896$

E) Temperature function is:
$T = 35 e^{-.00896 t} +52$
solving for t
$t = \frac{ln (\frac{T-52}{35})}{-.00896}$
Plug in T = 98.6
$t = -31.95$

This is approximately 32 minutes before he arrived or about 1:20 AM
