Answer:
If you had a bill of $45.00 and left an 18% tip then you would have left an $8.10 tip.
The slope is the change in y over the change in x, so it's (4-2)/(6-7)=2/-1=-2. Point slope form is y<span> – </span>y1<span> = </span>m(x<span> – </span>x1<span>), so we can plug in a point (6,4) to get
y-6=-2(x-4)</span>
Answer:
put the numbers in order from least to greatest and then cross them out til you get to the center number
Answer:
D(4,-3)
Step-by-step explanation:
Given three of the vertices of the square: A(4, -7), B(8, -7),C(8, -3)
Let the coordinate of the fourth vertex be D(x,y).
We know that diagonals of a square are perpendicular bisector. So, the midpoint of both diagonals is the same.
The diagonals are BD and AC
Midpoint of BD = Midpoint of AC

The coordinates of the fourth vertex is D(4,-3)
The total area of the blades is the area of a triangle multiplied by 4.
We have then:

Where,
b: base of the blades
h: height of the blades
Substituting values we have:

Doing the calculation we have that the area of the blades is given by:

Answer:
The total area of the blades is:
