Answer:

14

Step-by-step explanation:

Sin(∅) = Opposite angle ÷ hypotenuse.

Sin (45) = 7\sqrt{2} ÷ hypotenuse

hypotenuse = 7\sqrt{2} ÷ sin(45)

*********************

Keep in mind

sin(45) = √2÷2

*********************

so we have:  Hypotenuse = 7√2 ÷ (√2÷2)

Hypotenuse= 14.

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.
