Find the area of the blue shaded region. Round your answer to the nearest hundredth.
SSSSS [86.1K]

Answer:

173.01

Step-by-step explanation:

To area of a sector or portion of a circle is found using:

A = \frac{N}{360} \pi r^2

Substitute N = 50 and A = 27.93.

It becomes 27.93 = \frac{50}{360} \pi r^2\\27.93 = 0.139 \pi r^2\\200.94 = \pi r^2

The area of the entire circle is 200.94. The area of the blue part of the circle can be found by subtracting the red section from the entire circle.

200.94 - 27.93 = 173.01

Danielle wants to leave a 15% tip on her restaurant bill. The total she pays with the 15% is $94.30. What is her restaurant bill
Vlad [161]

Answer:

$628.67

Step-by-step explanation:

15% of her restaurant bill is $94.30.

15 goes into 100, 6 2/3 times. so we multiply both 15% and $94.30 by 6 2/3 to get 100% and the restaurant bill.

15% x 6 2/3 = 100%

$94.30 x 6 2/3 =

628.666666

or

$628.67

I hope that this helps! :)

HELP THIS IS HARD SOMEONE pls
IrinaK [193]

Answer:

3rd option

Step-by-step explanation:

Since the centre of dilatation is at the origin then multiply the coordinates by \frac{1}{3}

K (- 3, 9 ) → K' (- 3(\frac{1}{3} ), 9(\frac{1}{3} ) ) → K' (- 1, 3 )

L (- 9, 0 ) → L' (- 9(\frac{1}{3} ), 0 (\frac{1}{3} ) ) → L' (- 3, 0 )

M (2, - 8 ) → M' (2 (\frac{1}{3} ), - 8 (\frac{1}{3} ) ) → M' ( \frac{2}{3} , - \frac{8}{3} )

N (6, 4 ) → N' (6 (\frac{1}{3} ) , 4 (\frac{1}{3} ) ) → N' ( 2, \frac{4}{3} )
