Natsumi went on a business lunch. The pretax bill was $55.60. She decided

1 answer:

5 0

8.25% of 55.60 = 4.58700

We round that number to 4.59

(I am assuming the tip is based on the amount of the pretax bill.)

15% of 55.60 = 8.34

So $55.60 + $4.59 + 8.34 = $68.53

The bill would be $68.53.

11. D'(2.9) is the image of D after a reflection

algol [13]

Answer:

D(- 2, 9 )

Step-by-step explanation:

Under a reflection in the y- axis

a pont (x, y ) → (- x, y )

Given D'(2, 9 ) is the image of D, then

D(- 2, 9 ) ← are the original coordinates

Since D(- 2, 9 ) → D'(2, 9 )

the coordinates of the vertices of a rectangle in order are (5,2), (-1,4), (-2,1) and (4,-1). what is the perimeter of the recta

Anna [14]

Answer:

19 units

Step-by-step explanation:

Plot points A(5,2), B(-1,4), C(-2,1) and D(4,-1) on the coordinate plane. Find lengths of all sides as distances between two points:

$AB=\sqrt{(-1-5)^2+(4-2)^2}=\sqrt{6^2+2^2}=\sqrt{36+4}=\sqrt{40}=2\sqrt{10}\ units\\ \\BC=\sqrt{(-2-(-1))^2+(1-4)^2}=\sqrt{1^2+3^2}=\sqrt{1+9}=\sqrt{10}\ units\\ \\CD=\sqrt{(4-(-2))^2+(-1-1)^2}=\sqrt{6^2+2^2}=\sqrt{36+4}=\sqrt{40}=2\sqrt{10}\ units\\ \\DA=\sqrt{(5-4)^2+(2-(-1))^2}=\sqrt{1^2+3^2}=\sqrt{1+9}=\sqrt{10}\ units$

The perimeter of the rectangle ABCD is

$AB+BC+CD+DA=2\sqrt{10}+\sqrt{10}+2\sqrt{10}+\sqrt{10}=6\sqrt{10}\approx 18.97\ units\approx 19\ units$
