PLEASE HELP I WILL MARK AS BRAINLIEST

Answer 1

Answer:

$\large \boxed{\text{1. 24 doses; 2. 4614 mL}}$

Step-by-step explanation:

1. Prescription

(a) Calculate the volume of the mouthwash

Tetracycline              0 mL (it's a solid)

Nystatin                   40

Diphenhydramine   60

Dexamethasone    140        

TOTAL                   240 mL

(b) Calculate the number of doses

1 tsp = 5 mL, so a dose of

2 tsp = 10 mL

$\text{No. of doses} = \text{240 mL} \times \dfrac{\text{1 dose}}{\text{10 mL}} = \text{24 doses}\\\\\text{There are \large \boxed{\textbf{24 doses}} in the prescription.}$

2. Punch

You must convert gallons, pints, and cups to millilitres.

The conversion factors are

1 US gal = 3785 mL

 1 US pt =   473 mL

  1 US c =   237 mL

(a) Gallons to millilitres

$\text{No. of millilitres} = \frac{3}{4}\text{ gal} \times \dfrac{\text{3785 mL}}{\text{1 gal}} = \text{2839 mL}$

(b) Pints to millilitres

$\text{No. of millilitres } = \text{3 pt} \times \dfrac{\text{473 mL}}{\text{1 pt}} = \text{1419 mL }$

(c) Cups to millilitres

$\text{No. of millilitres} = \text{1.5 c } \times \dfrac{\text{237 mL}}{\text{1 c}} = \text{356 mL}$

(d) Volume of punch

Orange juice     = ¾ gal = 2839 mL

Ginger ale         = 3  pt    =  1419

Pineapple juice = 1½ c  =   356            

                         TOTAL =  4614 mL

$\text{The final volume of the punch is \large \boxed{\textbf{4614 mL}} }$
