Answer: 200
Step-by-step explanation: to get the radius you divided by 2. bc there is only 2 sides , have a great day.
Answer:
420 Mile's.
Step-by-step explanation:
First you figure out the unit rate by dividing 360 by 6 which is 60. So that's 60 miles per hour. Now multiply 60 by 7 to find out how many miles she will drive in 7 hours. When you multiply you get 420.
-x/y is equivalent to x/-y according to the division rule a/b*d/c=a/b*c/d.
<h3>Describe division.</h3>
In division, a number is divided, which is an easy operation. In mathematics, division is the division of a sum into equal parts. A group of 20 people, for instance, could be divided into four groups of 5, five groups of 4, and so on. Division's opposite is multiplication. If 3 groups of 4 add up to 12, then 4 are in each group when 12 is divided into 3 equal groups.
According to the division rule a/b/c/d=a/b*d/c,
=1/(y/-x)
=1*-x/y
=-x/y
-x/y is equivalent to x/-y according to the division rule a/b÷c/d=a/b*d/c.

Find Slope:
--------------------------------------------------------------------------------------------------------
y = 1/4x - 7
Slope = 1/4
Perpendicular slope = -4 (Negative reciprocal)
--------------------------------------------------------------------------------------------------------
Substitute slope into the general equation y = mx + b:
--------------------------------------------------------------------------------------------------------
y = -4x + b
--------------------------------------------------------------------------------------------------------
Find y-intercept:
--------------------------------------------------------------------------------------------------------
at point (-2, -6)
-6 = -4(-2) + b
-6 = 8 + b
b = -6 - 8
b = -14
--------------------------------------------------------------------------------------------------------
Substitute b = -14 into the equation:
--------------------------------------------------------------------------------------------------------
y = -4x + b
y = -4x - 14
--------------------------------------------------------------------------------------------------------
Equation:
--------------------------------------------------------------------------------------------------------
y = -4x - 14
y + 6 = -4x - 8 \\add 6 to both sides
y + 6 = -4(x + 2) \\Take out common factor -4
--------------------------------------------------------------------------------------------------------
Answer: y + 6 = -4(x + 2) (Answer D)
