A certain drug is made from only two ingredients: compound A and compound B. There are 6 milliliters of compound A used for every

5 milliliters of compound B. If a chemist wants to make

726

milliliters of the drug, how many milliliters of compound B are needed?

A certain drug is made from only two ingredients: compound A and compound B. There are 5 milliliters of compound A used for every 4 milliliters of compound B. If a chemist uses 255 milliliters of compound A, how many milliliters of the drug will be made?

4:5 is the same as 4x:5x where 4x is compound A and 5x is compound B.

---

Solve for "x":

If amount of compound A is 4x = 255

x = 255/4

Then amount of compound B is 5x = 5(255/4) = 318.75 ml

oak trees? ? what was listed

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
