First, you must find the tip. Multiply 55.50 by 0.2 (the decimal form of 20%). 55.50*.2=11.10. Next, find the sales tax. You don't pay tip on tax as the hint declares, but you also don't pay tax on the tip. Therefore, you must find 7% of 55.50 by multiplying 55.50 by 0.07 (the decimal form of 7%). 55.50*.07=3.885. You don't want to round until the very end, so we leave that in full form for now. Finally, add all your expenses: 55.50+11.10+3.885=70.485. Now to figure out how much each person will pay. There are six people paying, so 70.485/6= 11.7475. Finally, round to the nearest hundredth, otherwise known as the nearest cent, to get the answer of $11.75, or C.

What is the slope? What is the y-intercept? What is the equation of the line (slope intercept form?)
yawa3891 [41]

Answer:

                The slope is: m = -²/₅

               The y-intercept is:  b = -2

               The equation of the line: y = -²/₅x - 2

Step-by-step explanation:

  The equation of a line in slope intercept form: y = mx + b

The slope:   m=\dfrac{y_2-y_1}{x_2-x_1}

(-5, 0)   ⇒  x₁ = -5,  y₁ = 0

(0, -2)   ⇒  x₂ = 0,  y₂ = -2

So:

     m=\dfrac{-2-0}{0-(-5)}=-\dfrac25

Give the equation of the circle centered at the origin and passing through the point (0,5)
Julli [10]

Answer:

x^{2} +y^{2}=25

Step-by-step explanation

The standard equation of a circle centered at origin is  x^{2} +y^{2} =r^{2}

r = radius of the circle

The circle is passing through the point (0,5)

∴ radius  r=\sqrt{(0-0)^{2}+(5-0)^{2} }

               r=\sqrt{0+25}

               r=\sqrt{25}

               r^{2}=25

∴ The equation of the circle is

     x^{2} +y^{2} = 25
