Answer:
A =80.5 ft^2
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
The base is 14 ft and the height is 11.5 ft
A = 1/2 * 14 * 11.5
A =80.5 ft^2
right 3 units down 5 units
right 3 units = (3,0)
down 5 units = (0,-5)
vertex = (h,k) therefore.
Then convert the vertex form into standard form for the equation in the choice.
Thus, the answer is B.
Answer:
22
Step-by-step explanation:
The standard form for an equation of a circle is 
, where h is the x coordinate of the center of the circle, k is the y coordinate, and r is the radius of the circle. Therefore, the radius of this circle squared is 121, meaning that the radius of the circle is 11. Since the diameter of a circle is twice the radius, the radius of this circle is 22. Hope this helps!
Answer:
205 square ft
Step-by-step explanation:
1. Since his room is 12ft by 15.75ft, we can multiply to find the square ft needed to cover his room.
2. Since his closet is 2ft by 8ft, we can multiply to find the square ft needed to cover his closet.
3. Then, we add them to find how much carpeting is needed total.
4. (12*15.75)+(2*8)=189+16=205
