Answer:
Step-by-step explanation:
A shape exterior angles add up to 360.
All of these angles are exterior angles so we can add up all of them to and set it equal to 360 to find x.
N=28
cross multiply 7 and 36
cross multiply 9 and n
7x36=252
9xN=9n
9n=252

The probability of hitting the yellow square is 1/4.
The area of the yellow square is given by 3*3 = 9.
The area of the blue square is given by 6*6 = 36.
You have a 9/36 chance of hitting the yellow square; 9/36=1/4.
Answer:
y=-2x-1
Step-by-step explanation:
First we need to know the slope-intercept equation:
y=mx+b
m: slope
b: y-intercept
First we find the slope:
Slope = (y₂-y₁)/(x₂-x₁)
Use any two x and y values on the table:
Slope = [-5-(-3)]/(2-1) = -2/1 = -2
Now we find the y-intercept:
y=mx+b
y=-2x+b
We plug in a pair of x and y values into the equation:
-3=-2(1)+b
-3=-2+b
b=-1
So the slope-intercept equation is:
y=-2x-1
251.50 divided by 7.85 is 32 so she worked 32 hours.
