A party of 5 wants to add a tip of 20% to their total $175 bill

yulyashka [42]

Answer:

Hi, I think your question is incomplete. But I'll assume you're asking a party of 5 wants to add a tip of 20% to their total 175 dollars bill, how much do each person needs to pay?

Step-by-step explanation:

Firstly, calculate the percentage: 175 x 20% is 35, so 35 + 175 is 210.

210 ÷ 5 (Num. Of people in party)

Is 42 dollars. <em><u>Therefore each people need to pay 42 dollars. </u></em>

Match each quadratic equation with its solution set.

Marianna [84]

Answer:

( 8 , - 8) => x² - 55 = 9

( 4 , - 4) => 2x² - 32 = 0

(5 , - 5) => 4x² - 100 = 0

(11 , - 11) => x² - 140 = -19

( 3, - 3) => 2x² - 18 = 0

Step-by-step explanation:

1)

$2x^2 - 32 = 0\\\\2(x^2 - 16 ) = 0 \\\\x^2 - 16 = 0 \\\\x^2 = 16 \\\\x = \sqrt {16 } = \pm 4$

x = ( 4 , - 4)

2)

$4x^2 - 100 = 0 \\\\4(x^2 - 25 ) = 0\\\\x^2 - 25 = 0 \\\\x^2 = 25 \\\\x= \sqrt{25} = \pm 5$

x = ( 5 , - 5 )

3)

$x^2 - 55 = 9 \\\\x^2 = 9 +55\\\\x^2 = 64\\\\x = \sqrt{64} = \pm 8$

x= ( 8 , - 8)

4)

$x^2 - 140 = - 19\\\\x^2 = -19 + 140 \\\\x^2 = 121 \\\\x= \sqrt{121} = \pm 11$

x = ( 11 , -11)

5)

$2x^2 - 18 = 0\\\\2(x^2 - 9) = 0\\\\x^2- 9 = 0 \\\\x^2 = 9 \\\\x = \sqrt9 = \pm 3$

x = ( 3 , - 3)

Answer:

The center of the circle is (13.4, - 2.6).

Step-by-step explanation:

Circle:

The diameter of a circle is 2 times of its radius.
The area of a circle is $\pi r^2$ , where is the radius of the circle.

The circumference of a circle is $2\pi r$ , where r is radius of the circle.

We know that,the equation of circle is in the form

$(x-\alpha)^2+(y-\beta)^2= r^2$

where $(\alpha, \beta)$ is the center of the circle and r is the radius of the circle.

Given equation of circle is

$(x-13.4)^2+(y+2.6)^2=100$

The center of the circle is (13.4, - 2.6).

The radius of the given circle is $\sqrt{100}$ units=10 units.
