Given ADEF, which is not equal to cos(F)?<br> sin(F).<br> sin(D).<br> tan(F).<br> COS(D).
lorasvet [3.4K]

Answer:

tan(F)

Step-by-step explanation:

This is an isoceles triangle, both sides are the same so both the angles are the same as well. The sine and cosine of angles D and F are going to be the exact same because of the same sides. The only one that would be different would be the tangent of F or D.

cylinder with height 9 inches and radius is filled with water, it can fill a certain pitcher. How many of these pitchers can a c
larisa [96]

Answer:

4

Step-by-step explanation:

The 1st cylinder used to fill the pitcher has:

height:

h = 9 in

radius:

r = r

The volume of a cylinder is given by:

V=\pi r^2 h

Therefore, the volume of the 1st cylinder is

V=\pi r^2 9=9\pi r^2

We are told that the water inside this cylinder can fill a certain pitcher, so this is also the volume of the pitcher.

Then, we have a second cylinder, which has height

h = 9 in

and radius

r' = 2r

So the volume of this cylinder is

V'=\pi r'^2 h = \pi (2r)^2 9 =9\pi (4r^2)=36\pi r^2

This means that the number of pitchers that can be filled by this 2nd cylinder is

n=\frac{V'}{V}=\frac{36\pi r^2}{9\pi r^2}=4

frez [133]

Answer:

1 inch =  3 feet

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

6 /2 = 3

1 in = 3 feet
