Answer:
Step-by-step explanation:
3. V triangular prism =B*h=18*12*35=7560 cubic feet
4. V cone= pi*r^2*h=pi*8^2*9=3.14*64*9=1808.6 cubic feet
5. V=B*h/3=15*9*13/3=5*9*13=585 cubic milimeters
There is not relationship between the size of a school building and the number of students who play an instrument because the scatterplot does not have a cluster.
Answer: Option A.
<u>Explanation:</u>
A scatterplot is a type of data display that shows the relationship between two variables. It makes use of the Cartesian coordinates to plot the values of the two variables for a set of data. This is used to show how much is one variable is affected by the other variable.
Since in the scatterplot which is being talked about in this question, it is scattered and is not clustered, this shows that there is no relationship between the size of the school and the number of the students who play instruments in the school.

Answer:
Step-by-step explanation:
Since we want to know the actual number of feet, we can write the proportion with that in the numerator.

The real caboose is 42 1/4 feet long.
The length of the major arc LNM is 
<h3><u>Length of an arc</u></h3>
From the question,
We are to determine the value of the length of the major arc LNM
The length of the major arc LNM can be calculated using the formula

Where r is the radius
First, we will determine the value of the reflex ∠LKM
Reflex ∠LKM + ∠LKM = 360° (<em>Sum of angles at a point</em>)
From the given information,
∠LKM = 70°
Then,
Reflex ∠LKM + 70° = 360°
Reflex ∠LKM = 360° - 70°
Reflex ∠LKM = 290°
Also, from the question
r = 3 cm
Now, putting the parameters into the formula, we get

Then,


Hence, the length of the major arc LNM is

<h2>Answer</h2>
1.5n-3.2
<h2>Explanation</h2>
First, we need to distribute -1.5. To do it we just multiply each term inside the parenthesis by -1.5:



Now we just need to combine like terms:
