Two pyramids like the one below sit on top of the gates at the entrance to the bridge.
Which expression shows how to determine the minimum amount of cement used to make each of the pyramids?
1.1/3(10)(10)(12)
2.1/2(10)(10)(12)
3.4[1/2(10)(13)]+10(10)
4.4[1/3(10)(13)]+10(10)

step-by-step explanation: noo

which expression represents the approximate length of bc?

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
