Assuming the question is what Ivan is saying possible the answer is no based on multiplication. He could get at most 8 12-inch fence posts. 

12 x 8 = 96 leaving him 8 more inches of board. 
12 x 9 = 108 meaning he would need 4 more inches of lumber to make his last fence post uniform with the rest.

Anastasy [175]

Answer and Step-by-step explanation:

Let's~solve~your~problem!

<em><u>Formula : </u></em>

<u></u>speed=\frac{distance}{time}

<em><u>Solving for time:</u></em>

Time~taken~to~cover~40~miles~on~local~ roads~= \frac{40}{20}  = 2~hours

Time~taken~to~cover~180~miles~on~the~highway~= \frac{180}{60}=3~hours

Total~Time~=~5~hours

<em><u>Solving for distance:</u></em>

<em><u /></em>Total~Distance=40 + 180 = 220<em><u /></em>

<em><u /></em>

<em><u>Average speed:</u></em>

<em><u /></em>\frac{Total~distance}{Total~time}  = \frac{225}{5}  = 44~miles~per~hour<em><u /></em>

Short answer
For 6: 72 ft^2
For 7: 650 m^2

Six
The base is a square. It's measurement is s = 4
Base = 4^2 
Base = 16 ft^2

One triangle 
A = 1/2 * b * h
A = 1/2 * 4 * 7
A = 14 tt^2

Four triangles
A = 4 * 14
A = 56 ft^2

Total Area = 56 + 16 = 72 ft^2
Answer 72 square feet

Seven
Triangles
Area of 1 triangle = 1/2 * 10 * 13
Area of 1 triangle = 65


Area of 6 triangles
Area of 6 triangles = 6 * area of 1 triangle
Area of 6 triangles = 390

Base
As near as I can tell, the base is a hexagon. It's using a rather out of the way method of drawing it. I will assume it is a regular hexagon. The area of a regular hexagon is 3 sqrt(3)/2 * S^2 where s is the side of the hexagon.

Area = 3sqrt(3)/2 s^2
s = 10
Area = 3sqrt(3)/2 10^2
Area = 5.1962 * 100 /2
Area = 259.81

Total area
Total area = area of the base + area of the triangles
Total area = 259.81 + 390
Total area (rounded ) = 650

Answer C <<<< answer 

I'll do one more in this batch and then you'll need to repost again.

Eight

If you draw two diagonals on the base of the figure, the intersection point will meet the base of the height. Read that a couple of times.
Join the intersection to the midpoint of the length of the square bottom.  You should get 3.5

x is found by using the pythagorean theorem.
h = 6
s = 3.5
x = ????

x^2 = 6^2 + 3.5^2
x^2 = 36 + 12.25
x^2 = 48.25
x = sqrt(48.25)
x = 6.95
