CAN SOMEONE HELP ME !!!!!!!!!
MissTica

Answer:

She will get <u>80mg</u> of dextromethorphan and <u>800mg</u> of guaifenesin. And the bottle last for <u>6 days</u> approximately.

Step-by-step explanation:

Given that the Robitussin DM contains dextromethorphan 10mg/5mL and gualfenesin 100mg/5mL. And we are also given that Mrs Smith took four doses and each dose is 2 teaspoons=2X5=10mL.

So, four doses=4X10=40mL.

So, dextromethorphan in 4 doses is = \frac{10}{5}X40=80mg

And Guaifenesin in 4 doses is = \frac{100}{5}X40=800mg

Dosage of medicine daily she has to take=40mL and the bottle contains 237 mL. Hence the number of days bottle last = \frac{237}{40}=5.925≈6 days approximately.

Una persona pensó hacer una obra en 15 días; pero tardó 10
Ivenika [448]

Answer:

<em>Trabajó 3 horas al día</em>

Step-by-step explanation:

<u>Proporcionalidad</u>

Una persona planeó terminar la obra en 15 dias, pero tardó 10 dias adicionales porque trabajó 2 horas menos por día.

Usaremos proporciones para calcular las horas de trabajo diarias.

Si 2 horas diarias representan 10 dias de atraso, entonces cada hora representa 5 dias de trabajo.

Si la obra tardaba 15 dias, entonces la persona trabajó 15/5 = 3 horas diarias.
