Answer:
39.19 yards^2
25.15 yards
Step-by-step explanation:
To determine the squares square yards of carpet needed, we have to determine the area of the room
The room is shaped like a rectangle
area of a rectangle = length x breadth
5.7 x 6 7/8
To multiply, convert 6 7/8 to a decimal
to do this, divide 7 by 8. Add the value gotten to 6
5.7 x 6.875 =39.19 yards^2
To determine the yards needed for the border, calculate the perimeter of the room
Perimeter = 2 x (length + breadth)
2 x(5.7 + 6.875) = 25.15 yards
Answer:
-83n -99
Step-by-step explanation:
Do -3(n+3)-10(8n+9) which is -3n-9 ; -80n-90, and then combine like terms.
Answer:
a=12
b=9
Step-by-step explanation:
3/4 of 12 is 9 and 9 plus 12 is 21
-.25a-4=4
Add for on both sides
-.25a=8
Divide by -.25
A=
Angle R is an inscribed angle. By the inscribed angle theorem, angle O (which is a central angle corresponding to the same arc as angle R) will be double that of angle R.
So in short,
(central angle O) = 2*(inscribed angle R)
(central angle O) = 2*(23)
(central angle O) = 46 degrees
The final answer is 46 degrees
