When baking cookies, a recipe calls for 2 cups of flour and 1 cup of sugar for every 12 cookies. How many cookies can you make with 28.2 cups of flour?

169

Step-by-step explanation:

12 cookies ÷ 2 cups of flour = 6 cookies per 1 cup of flour

28.2 × 6 = 169.2

Therefore, you can make 169 cookies with 28.2 cups of flour.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
