Answer:
B.)8ft
Step-by-step explanation:
Set up a proportional to the roof slope:
2/5 = x/20
Cross multiply:
40/5 = 5x/5
x=8ft
Answer:
60.39 inches
Step-by-step explanation:
Given that:
A Pac-Man poster which is having three fourth of a circle and there are two sides.
Diameter of circle = 18 inches
Sides of Pac-Man poster = 9 inches
To find:
Perimeter of the Pac-Man poster.
Solution:
Perimeter of a figure is nothing but equal to the periphery i.e. the outer area of the circle/figure.
Perimeter of a circle is given by the formula:
Perimeter = ![2\pi r](https://tex.z-dn.net/?f=2%5Cpi%20r)
is the radius of the circle.
Radius is half of perimeter.
![r=\dfrac{18}{2} = 9\ inches](https://tex.z-dn.net/?f=r%3D%5Cdfrac%7B18%7D%7B2%7D%20%3D%209%5C%20inches)
Perimeter of the Pac-Man poster = Perimeter of
circle + 2 sides
Perimeter of the Pac-Man poster =
+ 9+9 = 42.39+28 = <em>60.39 inches</em>
Answer:
(1, 5 )
Step-by-step explanation:
Choose any value of x, substitute into the equation and solve for y
x = 1, then
4(1) + y = 9, that is
4 + y = 9 ( subtract 4 from both sides )
y = 5
Thus (1, 5 ) is a solution to the equation
