Answer:
d = 576
Step-by-step explanation
Think of the two different speeds as belonging to 2 different cars going to the same place, taking the same route and going to the same place.
Let the time traveled by the fast car = t
Let the time traveled by the slower car = t+4
Let the rate of travel of the slow car = 36 mph
Let the rate of travel of the fast car = 48 mph
===========
d = 36*(t + 4)
d = 48 * t
Since the distance is the same, they can be equated.
48t = 36(t + 4) Remove the brackets.
48t = 36t + 144 Subtract 36t from both sides.
48t - 36t = 144 Combine
12t = 144 Divide by 12
t = 144/12
t = 12
Therefore the faster car takes 12 hours to get where it is going.
d = 48 * t
d = 48 * 12
d = 576
Answer:
The answer is "The Last choice".
Step-by-step explanation:
Please find the complete question in the attached file.
It is the phrase that perfectly represents the usage of a simulation for an estimate of the likelihood of the birthday of 2 randomly chosen persons on a Monday.
In a week there are 7 days, so seven choices are available, and just one Monday. Therefore, it is probable that
will occur on a Monday to a birthday individual.
The first person will have a probability
.
The second person also has a probability
.
Answer:
9 m³
Step-by-step explanation:
This block has the shape of a rectangular prism.
The volume of such a prism is A = (length)(width)(height).
Here, the volume is V = (3 m)(1.5 m)(2 m) = 9 m³
<span>8t-r=12t
Add r to both sides
8t=12t+r
Subtract 12t from both sides so that t can only be on one side
-4t=r
Divide both sides by -4
Final Answer: t= r/-4</span>
