A recipe that makes 10 blueberry muffins calls for 1 1/4 teaspoons of baking powder. How much baking powder is needed to make 3 dozen muffins?

4 1/2 teaspoons

Step-by-step explanation:

First, divide 1.25, aka 1 1/4, by 10 to get .125, then multiply .125 by 36 because 12 x 3 = 36. Then, at the end you get 4.5 teaspoons (4 1/2)

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

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
