The dose of a strong cough medicine might be which of the following? 2mL, 200mL, 2L

1 answer:

6 0

To find the answer,we can picture how much the above value is by objects in real life.

2mL = about two drops of water

200mL = about a carton of milk/ a box of ornage juice

2L = 2000 × 10 mL = 20000 mL = The bottle of drinks that are in family/party size.

As we only take in small dosages of medicine, the best option would be 2mL.

Hope it helps!

If sin(x) = squareroot 2 over 2 what is cos(x) and tan(x)

Bumek [7]

Answer:

cos(x) = square root 2 over 2; tan(x) = 1

Step-by-step explanation:

$\frac{\sqrt{2} }{2}$

was, before it was rationalized,

$\frac{1}{\sqrt{2} }$

Therefore,

$sin(x)=\frac{1}{\sqrt{2} }$

The side opposite the reference angle measures 1, the hypotenuse measures square root 2. That makes the reference angle a 45 degree angle. From there we can determine that the side adjacent to the reference angle also has a measure of 1. Therefore,

$cos(x)=\frac{1}{\sqrt{2} }=\frac{\sqrt{2} }{2}$ and

since tangent is side opposite (1) over side adjacent (1),

tan(x) = 1

15) The diameter of a cylinder is 12 and height is 11. Find the surface area of the figure.

kirza4 [7]

Answer:

A=640.88

Step-by-step explanation:

if the diameter is 12, the radius , r=12/2=6

we have r=6, h=11

Surface area, A= 2πrh+2π r^2

A=2*3.14*6*11+2*3.14*(6)^2=640.88
