Hey there, the answer is C.

After multiplying, you will get .37278. However, it's asking you to consider the significant figure of 3 so you'll have to round it to .373. C has that only option

A cable is installed around two edges of the rectangular field that is 860 feet long and 340 feet wide, as shown below. Suppose
raketka [301]

Answer:

<em>a. 2,520,000.00</em>

<em>b. $1,942,017.51</em>

<em>c. $577,982.49</em>

Step-by-step explanation:

<u>Distances in a Rectangle</u>

a.

Running the cable along the edges of the field would need a total length of 860 ft + 340 ft = 1,200 ft of cable. The unit cost of the cable is $2,100 per foot, thus the cost of the total lenght of cable was 2,100*1,200= $2,520,000.

b. If the cable ran along the diagonal, the distance must be computed by

D=\sqrt{x^2+y^2}

where x = 860 ft and y = 340 ft, thus

D=\sqrt{860^2+340^2}=924.77

D = 924.77 ft. The cost of the cable would be 2,100*924.77= $1,942,017.51

c. The savings if the cable were installed along the diagonal of the field instead of around the edges of the field would be

$2,520,000 - $1,942,017.51 = $577,982.49

Which example shows the additive inverse of a number?
earnstyle [38]

An example of an additive inverse of a number is:

7 + (-7) = 0

No matter what, your sum needs to be 0, as the inverse of the number is the same number only with a different sum. (for example: -8 & 8, -10 & 10, etc)

hope this helps
