Answer:
The slope of the green line is 3.
Step-by-step explanation:
<em><u>Definition: </u></em>If the two lines are said to be perpendicular, than the multiplication of their slope is -1.
In other words, the slope of the perpendicular line is the negative reciprocal of the given slope of the line.
Here we are slope of the red line, which is -1/3
Let's take it as "m1"
Let's take "m2" the slope of the green line.
By the above definition,
Given:
Now plug m1 value in the above statement, we get
Multiply both sides by reciprocal of -1/3. The reciprocal of -1/3 = -3
Therefore, the slope of the green line is 3.

Answer:
x=15
Step-by-step explanation:
The given equation is
Here the variable is x and the terms with the variable are
Keep all the terms having variable on one side and all the constants terms on the other side as
Now, simplify the above equation to get the value of x as
In this way, the value of x is 15.
Answer: option D. 0.785
Explanation:
1) the probability will be equal to the area of the shaded region divided by the area of the rectangle:
area of the shaded region
probability = -------------------------------------
area of the rectangle
2) call r the radius of the circles (all are equal)
area of one circle = π (r^2)
area of the four circles = 4π(r^2) = area of the shaded region
3) area of the rectangle
length of the rectangle: 2r
height of the rectangle: 8r
area of the rectgangle = (2r)(8r) = 16 r^2
4) probability = 4π(r^2) /[(16)(r^2)] = π / 4
use π = 3.1416
probability = 3.1416 / 4 = 0.785
And you do not need to use the diameter given. The answer does not depend on this number.
