Acity dumps plastic shade balls into a reservoir to prevent water from evaporating during a drought. it costs $5760 for 16,000 shade balls. how much does it cost for 12,000 shade balls?

$4320

Step-by-step explanation:

If it costs $5760 for 16,000 shade balls, then it would cost for 1 ball.

Hence to find cost of 12,000 balls, we need to multiply $0.36 with 12,000.

So

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

to complete this square you have to rotate about the origin 270 degrees clockwise.
