In a certain chemical, the ratio of zinc to copper is 3 to 11. A jar of the chemical contains 385 grams of copper. How many grams of zinc does it contain?

35 grams

Step-by-step explanation:

The ratio of zinc to copper is 3 to 11

A jar of chemical contains 385 grams if copper

Therefore the number of grams of zinc it contains can be calculated as follows

3/11= x/385

11x= 385

x= 385/11

= 35 grams

Hence the chemical contains 35 grams of zinc

be more specific

step-by-step explanation:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
