20 mins = 2/15 miles

----------------------------------
Find 1 min :
----------------------------------
1 min = 2/15 ÷ 20

1 min = 2/15 x 1/20

1 min = 1/150 miles

----------------------------------
Find 60 min :
----------------------------------
60 mins = 1/150 x 60 

60 mins = 2/5 miles

--------------------------------------------------------------------
Answer: 2/5 miles can be paved in 1 hour.

Given the line below.
Assoli18 [71]

Answer:

y + 1 = \frac{1}{2} (x + 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - y₁ = m(x - x₁)

where m is the slope and (x₁, y₁ ) a point on the line

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 2, - 1 ) and (x₂, y₂ ) = (2, 1 )

m = \frac{1-(-1)}{2-(-2)} = \frac{1+1}{2+2} = \frac{2}{4} = \frac{1}{2} and (x₁, y₁ ) = (- 2, - 1 ) , then

y - (- 1) = \frac{1}{2}(x - (- 2) ) , that is

y + 1 = \frac{1}{2} (x + 2)

if each interior angle of a regular convex polygon is three times the measure of each exterior angle, what kind of polygon is it
Julli [10]
The interior angle of a regular polygon is equal to 180(n - 2)/n. The exterior angle is always equal to 360/n. Using the given relationship from the item above, the equation that can be formed is,

     180(n - 2)/ n = 3(360/n)

The value of n from the equation is 8. The polygon with 8 sides is an octagon.

<em>Answer: OCTAGON</em>
