Amelia's reliable fencing co. prices fences based on the amount of fencing installed plus a fixed amount of $200. the company charges $4 per foot of standard fencing. which of the following scenarios is correct?

it costs $1480 to enclose an 80′ by 80′ rectangular area.
it costs $2600 to enclose a 10′ by 60′ rectangular area.
it costs $1040 to enclose a 90′ by 40′ rectangular area.
it costs $560 to enclose a 50′ by 40′ rectangular area.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

imma say 16%. sorry if its wrong. i'm doing the same stuff right now

step-by-step explanation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
