Answer:
54 movies
Step-by-step explanation:
shelving unit has 4x + 6 movies
and each holds 12 movies,
then x =12
Then solve 4x + 6 for x= 12
4(12) + 6 = 54
Answer:
Step-by-step explanation:
Coordinates of point B = (8, -6)
<u>Reflection across the x-axis results in:</u>
<u>Coordinates of B'</u>
- (8, -6) → (8, -(-6)) = (8, 6)
Answer:
Angle Z wil change because the side length is getting longer and tbe triangle would no longer fit the conditions
Divide 2 cakes by 2/3 serving:
2 / 2/3 = 2 x 3/2 = 6/2 = 3 servings.
Answer:
The refrigerator was at around 13 ∘C
Step-by-step explanation:
Newton's Law of Cooling:
The rate of change of a body temperature (amount of heat loss/time of loss) is directly proportional to the difference between its own temperature and the surroundings.

T ⇒ temperature
t ⇒ time
Tenv ⇒refrigerator temperature
⇒ rate of change of he temperature
-h ⇒ constant of proportionality (negative because the temperature is decreasing inside the refrigerator)
We have 3 points:
time (minutes) - Temperature (∘ C)
0 (when the pan was put in the refrigerator) - 46
15 (after 15 minutes) - 27
30 (15 minutes after the first 15 minutes) - 19
= -h (27 - Tenv)
= -h (19 - Tenv)
Now we have a system of two equations and two variables


The refrigerator was at around 13 ∘C
