Answer:

C. 50 (.20) + 20

Step-by-step explanation:

50 is the numbers of cookies so in order to find the total cost of JUST cookies we multiply 50 by .2 which is each cookies cost.

Then we add an additional 20 for the box.

So we get 50 (.2) + 20.

*BONUS* The total cost for one box is $30

What is the area of a sector<br> when r = 3 and 0 = 2.75 radians?

Ivahew [28]

Area of circle: A=pi×r². This area coresponds to 360degrees, or 2×pi radians.

2×pi ....... pi×r²

t radians....x

where t=2.75rads

Area of t: x=pi×r²×t/2/pi=r²×t/2

Area of t: 3²×2.75/2=9×2.75/2=12.375

Answer: the area of 2.75 radians is 12.375

What is the equation of the line?

hjlf

Answer:

$c)y=\frac{1}{2}x+2$

Step-by-step explanation:

$We\ know\ that,\\The\ equation\ of\ a\ graph\ is\ given\ by\ the\ formula:\\y=mx+b,\ where\ m\ is\ the\ slope\ of\ the\ graph,\ and\ b\ is\ the\ y-intercept;\\Here,\\First,\\Lets\ calculate\ the\ slope\ of\ the\ graph:\\We\ also\ know\ that,\\Slope(m)=\frac{rise}{run}=\frac{y_2-y_1}{x_2-x_1}\\Lets\ consider\ any\ two\ points\ which\ lie\ on\ the\ line:\\(2,3),(-2,1)\\Hence,\\The\ slope\ of\ the\ given\ line=\frac{1-3}{-2-2}=\frac{-2}{-4}=\frac{1}{2}\\Hence,\\m=\frac{1}{2}\\$

$Now,\\The\ y-intercept\ is\ the\ point\ at\ which\ the\ graph\ intersects\ the\ whole\ y-axis.\\Hence,\\Here,\\The\ line\ of\ the\ graph\ cuts\ the\ y-axis\ at\ (0,2).\\The\ y-intercept\ of\ the\ line=2\\Hence,\\The\ equation\ of\ the\ line:\\y=(\frac{1}{2})x+(+2)\\y=\frac{1}{2}x+2$
