Answer:

1/ 112

Step-by-step explanation:

1-½ = ½ ( Mr. Daniel's leftover)

½×½= ¼ ( Mr. Richie)

½×¼= 1/8 ( Ms Laura)

½×1/8 = 1/16 ( Ms. Kimberly)

1/7 × 1/16 = 1/ 112 (the last turn)

so, Ms. Sarah eats 1/ 112 of a piece.

Measurement of a circle<br><br> (Giving brainliest for the correct answer)

docker41 [41]

Answer:

A. $\frac{5}{6}\pi x^2$

Step-by-step explanation:

Central angle of shaded part

$\theta = 360\degree-60\degree= 300\degree$

Radius (r) = x unit

Area of the shaded part of $\odot K$

$= \frac{\theta}{360\degree} \times \pi r^2$

$= \frac{300\degree}{360\degree} \times \pi x^2$

$= \frac{5}{6}\pi x^2$

Complete the point slope equation of the line through(-1,-10)and(5,2).<br>y-6=

Lynna [10]

Answer:

Step-by-step explanation:

The point-slope of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the poinys (-1, -10) and (5, 2). Substitute:

$m=\dfrac{2-(-10)}{5-(-1)}=\dfrac{12}{6}=2$

Put the value of the slope and the coordinateso f the point (5, 2), to the equation of a line:

$y-2=2(x-5)$

In the question we have y - 6 = ...

Therefore

$y-2=2(x-5)$ <em>subtract 4 from both sides</em>

$y-6=2(x-5)-4$ <em>use the distributive property</em>

$y-6=2x-10-4$

$y-6=2x-14$ <em>distributive</em>

$y-6=2(x-7)$
