Answer: 
Step-by-step explanation:
Using the data given in the exercise, we can draw the diagram attached, where "h" is the height of the building reached by the top of the ladder.
Notice that there are two similar triangles.
So, you can set up the following proportion:

Finally, in order to calculate the height on the building reached by the top of the ladder, you must solve for "h".
Therefore, the value of "h" is :

Answer:
B
Step-by-step explanation:
Because there is three numbers
Answer:
b = $375
Step-by-step explanation:
b = cost of the bench
t = cost of the table
t = b - 78
b + b - 78 = 672
2b = 750
b = $375
Answer:
The area of the cone is "1,695.6 cm³".
Step-by-step explanation:
The given values are:
Diameter of cone,
d = 18 cm
then,
Radius,
r = 
= 
= 
Height,
h = 20 cm
As we know,
⇒ Area of a cone = 
On substituting the given values in the above formula, we get
⇒ = 
⇒ = 
⇒ = 
⇒ = 
The question is asking you to organize the data in line plot form. to do so you must create a number line (which in this case is provided for you) and put X's above the numbers. for example lets say your given the following data :
1, 2 ,2 , 4 , 1 , 3 , 2 , 5
this is how you would graph it in line plot form
x . x
x . x . x . x . x
_________________________________________
1 . . . 2 . 3 . 4 . 5
but in your case not al the numbers listed are on the plot so instead you do this:
x . x
x . x . x . x . x
___________________________________
1 . 3 . 5 .
plot as if the numbers are there. ( as usual spacing is important)
