A solution strength of \(15 \mathrm{mg}\) of medicine in \(1 \mathrm{ml}\) of solution is available. If a patient needs \(12 \mathrm{mg}\) of medicine, how many \(\mathrm{ml}\) do you administer?

Solve each proportion for the given variable. Round the solution where indicated. $$ \frac{\frac{1}{3}}{\frac{3}{8}}=\frac{\frac{2}{5}}{n} $$

A solution strength of \(15 \mathrm{mg}\) of medicine in \(1 \mathrm{ml}\) of solution is available. If a patient needs \(33 \mathrm{mg}\) of medicine, how many \(\mathrm{ml}\) do you administer?

Solve each proportion for the given variable. Round the solution where indicated. $$ \frac{\frac{7}{9}}{\frac{8}{27}}=\frac{\frac{1}{4}}{n} $$

Solve each proportion for the given variable. Round the solution where indicated. $$ \frac{12}{n}=\frac{\frac{2}{3}}{\frac{6}{9}} $$

Solve. See Example 12. The playing field for football is a rectangle that is 300 feet long by 160 feet wide. Find the length of a straight-line run that started at one corner and went diagonally to end at the opposite corner. Round to the nearest foot, if necessary.

A solution strength of 8 mg of medicine in 1 ml of solution is available. If a patient needs \(10 \mathrm{mg}\) of medicine, how many \(\mathrm{ml}\) do you administer?

Solve each proportion for the given variable. Round the solution where indicated. $$ \frac{24}{n}=\frac{\frac{8}{15}}{\frac{5}{9}} $$

Write each rate as a unit rate. See Examples 9 and \(10 .\) Charlie Catlett can assemble 250 computer boards in an 8 -hour shift while Suellen Catlett can assemble 402 computer boards in a 12 -hour shift. a. Find the unit rate of Charlie. b. Find the unit rate of Suellen. c. Who can assemble computer boards faster, Charlie or Suellen?

A solution strength of 8 mg of medicine in 1 ml of solution is available. If a patient needs \(6 \mathrm{mg}\) of medicine, how many \(\mathrm{ml}\) do you administer?
