Remark
Supplementary angles = 180°

Givens
Let the supplement = x
Let the original angle = 8x

Formula
x + 8x = 180°

Solve
9x = 180°  Divide by 9
x = 180/9
x = 20

Answer
The original angle = 8*20 = 160°
The Supplement = 20°

A countertop is 11 feet long and 4 fee t wide.
zloy xaker [14]

Answer:

4.09m^2

Step-by-step explanation:

A countertop is 11 feet long and 4 fee t wide.

Using the conversion

1foot = 0.305 meter

11fet = 11(0.305)

11feet = 3.355 m

4 feet= 4 * 0.305

4feet = 1.22m

Area of the countertop = Length * Width

Area of the countertop = 3.355 * 1.22

Area of the countertop = 4.0931m^2

Hence the required area is 4.09m^2 to 2 decimal places

What is the midpoint of the segment
Solnce55 [7]

(-3,4)(-6,-1)

The easy way

look at the y's = 4 and -1 the difference is 5 now /2 = 2.5

so the y midpoint is 2.5 from each point or 1.5

look at the x's = -3 and -6 the differebce is 3 now /2 = 1.5

so its 1.5 from each point or -4.5

so midpoint is (-4.5, 1.5) or (-9/2, 3/2)  or C


the formula way:

for x

x1+x2/2

-3+-6/2

-9/2 (which is -4.5)

for y

y1+y2/2

4+-1/2

3/2 (which is 1.5)
