HELP A recipe calls for 1/2 cup ingredient a for every 1 2/3 cups of ingredient b. you use 2 cups of ingredient a. how many cups of ingredient b do you need?

A : B :: 1/2 : 4/3   proportion

4 : B :: 1/2 : 4/3   substitution

(1/2)B = (4/3)(4)  product means/extremes

4/(1/2) = 8

8 * 1 1/3 = 8 8/3 = 10 2/3 cups of B

Step-by-step explanation:

THIS IS PROBALY NOT RIGHT! DONT COPY!

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

you,

mrb

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
