Diana baked 39 cookies with 3 scoops of flour. How many scoops of flour does Diana need in order to bake 169 cookies? Solve using unit rates.

Diana needs 13 scoops of flour to bake 169 cookies.

Step-by-step explanation:

well, first you need to find the unit rate.

if 3 scoops of flour makes 39 cookies,

then 1 scoop of flour makes 13 cookies. (39/3)

next, since the unit rate is 13 cookies per flour-scoop, divide 169 by 13 to get your answer.

169/13 = 13

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

other answer is correct. i had used the radius of the radius somehow. a website:
