Answer:</h2>
- How many hours does it take for 11 centimeter of snow to accumulate in Harper's yard? 2.2 hours which is 2 hours 12 minutes
- How many centimeters of snow accumulate per hour? 5 centimeter
<h2>
Step-by-step explanation:</h2>
We know, that d means depth. Also, we know that h means hour.
d=5h basically means this: depth is equal to 5cm times hours
We have to questions to answer here. We already answered the second question. To answer first question, we just divide 11/5 ...That is 2.2 hours. That is 2 hours and 12 minutes.

I hope I helped you. I will be grateful, if you mark my answer as the brainliest.
Answer: Train A = 50 mph; Train B = 30 mph
Step-by-step explanation:
In this case, let's call the speed of both trains as:
Va: speed of train A
Vb: speed of train B
As train A is faster than train B, let's call speed of train B as X; So if Vb is X, then Va would be:
Vb = X
Va = X + 20
If we combine both Speed, we have:
V = Va + Vb = X + X + 20 = 2X + 20
Now that we have an expression for the combined speed, let's recall the formula for speed in general:
V = d/t
Where:
d: distance = 240 miles
t: time = 3 hours
Combining all the data we have:
V = 240/3
but V is 2X + 20 so:
2X + 20 = 240/3
Solving for X:
2X + 20 = 80
2X = 80 - 20
2X = 60
X = 60/2
X = Vb = 30 mph
Now that we know speed of one train, we can know the speed of the other train:
Va = 30 + 20 = 50 mph
Answer:
1. X= 56
2. X= -11/2 (When you solve you get this if you need it as a mixed number it's X= -5 1/2
Step-by-step explanation:
simplifying means: Reducing to lowest terms.
To solve for x simplify both sides of the equation, then isolate the variable.
For this case, the first thing we must do is observe that the graph has two asymptotes.
A horizontal asymptote or equivalently:
A vertical asymptote or equivalently:
Therefore, the domain and the range of the function is the same:
All reals excluding zero.
Answer:
The domain and range is the mime:
All reals excluding zero.

<u>Question 5</u>
Lets plug in values of x and y into each equation to see which one works for the entire data set...
y=2x-4
1) Plug in -7 as x and -18 as y:
-18=2(-7)-4
2) Multiply:
-18=-14-4
3) Subtract:
-18=-18
The answers are the same, therefore the correct answer to question 5 is equation D. Keep in mind, you want to check ever single pair of points to make sure it works for all of them, I'm just not going to list that as it would make this answer a lot longer for no reason.
<u>Question 6:</u>
We know that the cost for the boat is $25 as a base price, and also costs an additional $1.30 per day for fuel.
The correct equation is C=25+1.30d, because we are adding 1.3 every single day.
