We can easily break this down into four triangles.  There will be one on the top right, bottom left and also in opposite corners.  Using the formula A = 1/2bh, we can find that the area of the four triangles are 1120, 2063, 16091 and 21689. If we add up the area of the four triangles, we get 1120 + 2063 + 18091 + 21689 = 42963 ft^2.  Since the total cost $168,240, we know the cost per square foot is 168240/42963 = $3.92.  So in other words, Mr. Hewitt will get his land, but barely.

Are 3:5and 1:2 equivalent
german

Answer:

No. They are not equivalent.

Step-by-step explanation:

\frac{3}{5} \neq  \frac{1}{2}

=> \frac{6}{10} \neq  \frac{5}{10}

Therefore, 3/5 and 1/2 are not equivalent.

In example 4, the volume of the beach ball is 17,000 cubic inches. Find the radius to the nearest inch. Use 3.14 for pi
blagie [28]

Volume of a sphere formula is: V=4 /3 πr^3

You know v=17000 and pi=3.14

17 000 = 4/3 x 3.14 x r^3

(divide 17 000 by 4/3 x 3.14 ) --> r^3 = 4060.51 (2dp)

(cube root is to get just r) r = 15.95 inches (2dp)

There 15 inches to the nearest inch.

Hope this is correct! :D
