27 square yards roughly. 6*4.5=27 feet for one bulletin board. 27*3 is 81 for all three bulletin boards, then you divide by three to convert to square yards and get 27 square yards! Hope this helps!

Answer:
perimeter ≈ 12.4 units
Step-by-step explanation:
The side adjacent to the angle is given. The relationships useful for the other two sides are ...
Tan = Opposite/Adjacent
Cos = Adjacent/Hypotenuse
From these, we have ...
opposite = 5·tan(22°) ≈ 2.02
hypotenuse = 5/cos(22°) ≈ 5.39
Then the perimeter is ...
P = a + b + c = 2.02 + 5 + 5.39 = 12.41
The perimeter of ∆ABC is about 12.4 units.
Y is usage so set y to 0 and solve for x
y = -10x+100
0 = -10x +100
subtract 100 from each side:
-100 = -10x
divide both sides by -10
x = -100 / -10
x = 10 hours
Answer:
Slope is 1/2
Y- intercept is -2
Step-by-step explanation:
Re-write the equation so that u have y = x/2 -4/2
Then simplify into y = 1/2x -2
