Megan uses 2/3 cup of almonds to make 4 cups of trail mix. using this same proportion how many cups of almonds would megan need to make 9 cups of trail mix?

Megan needs 1 and 1/3 cup of almonds to make 9 cups pf trail mix.

Step-by-step explanation:

I'm not good with ratios and fractions so I drew an illustration.

I found out that 1/6 of almond cup is equivalent to 1 cup of trail mix.

So I add 2/3+2/3+1/6

I changed the denominator of 2/3 to 6 and divided 6 by 3 then multiply the answer by 2, then the product will be the numerator.

(6÷3) = 2 (2x2) =4

So, 4/6+4/6+1/6= 9/6

Simply the sum and it will be 1 and 1/3.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
